BURWEN BOBCAT TONE BALANCER is a unique tone control and high frequency reverberation system that consists of two parts.

BURWEN BOBCAT TR performs digital signal processing as a plug-in for the Windows Media Player.  When open, it processes recorded sound
during ripping, playing, or burning, and converts multiple WAV, MP3 and WMA music files to Burwen processed MP3 or WMA lossless files.   
Its Pure Bobcat button selection uses patent pending high-frequency reverberation to restore the original intended sound.  Its Smooth button
adds fixed equalization and NO SCREECH dynamic equalization to reduce shrillness without muffling high frequencies.

BURWEN TONE BALANCER.xls generates filter coefficients from 6 tone sliders and 3 high frequency reverberation button selections.  It sends
them to the digital signal processing program, BURWEN BOBCAT TR to substitute your own sound.  For each change in sound It utilizes the
huge calculating power of Microsoft Office Excel to evaluate 1,400,000 long formulas that control the sound of 1 to 7 output channels either
locally or by wireless remote control.
INSTALLATION AND ACTIVATION
  1. Only one Burwen digital signal processing product can be installed on your computer at any given time.  Before installing BURWEN BOBCAT TONE
    BALANCER, go to the Control Panel, Add/Remove Programs or Uninstall a Program and properly uninstall your previous product.  This applies to
    BURWEN BOBCAT RE, BURWEN BOBCAT DX, or BURWEN AUDIO.
  2. AUDIO SPLENDOR.xls and BURWEN BOBCAT TONE BALANCER.xls are Excel workbooks and more than one can be installed at the same time.  
    More than one can be open at the same time, provided they all have different names.
  3. Place your setup file BBTBsetup.exe in a new folder C:\BURWEN BOBCAT.  Be sure your Internet connection is still working.
  4. Double click BBTBsetup.exe to open the installation window.
  5. Install BURWEN BOBCAT TR first by clicking the BURWEN BOBCAT TR button.  Folow the instructions at www.burwenbobcat.
    com/BBTR_Instructions.html.
  6. Click the BURWEN BOBCAT TONE BALANCER.xls button to start its installation.  In all security dialog boxes that pop up, allow setup to run.
  7. BURWEN BOBCAT TONE BALANCER.xls is an Excel workbook.  It functions only with BURWEN BOBCAT TR or BURWEN AUDIO digital signal
    processing products and does not require separate activation.
FOR MULTICHANNEL OUTPUT
  • Firewire (IEEE 1394) connector
  • Audio Interface, Mark of the Unicorn, MOTU 828MK3 FireWire only.
  • Firewire cable for Notebooks, Comprehensive FW6P-FW4P-25ST 6 pin to 4 pin, 25 ft or shorter
TWO ACTIVATIONS
Your serial number is set to allow one extra activation in case your computer fails or you want to transfer your BURWEN BOBCAT software to a new
computer.  Your license does allow use on two different computers operated by the same one person.  The BURWEN BOBCAT TONE BALANCER which
includes BURWEN BOBCAT TR can be installed on your main computer and on a remote control laptop.  Both parts of the program are needed on each
computer and they must be the same version.  You might want to use the programs both at home and at your office.

If you have used both activations and experience a computer failure, Burwen Technology, Inc. can help you.  Contact us and request an extra activation
for your serial number.
PROCESS AUDIO
Clicking PROCESS AUDIO sends the calculated filter coefficients to BURWEN BOBCAT TR to change the sound processing to your latest control
settings.  The VOLUME slider, 4 reverberation buttons, and 2 CH BYPASS work independently and do not require clicking PROCESS AUDIO.

GRAPH
Clicking GRAPH opens the GRAPH window which shows a plot of the overall frequency response due to the combined tone slider settings.  If you want to
see the action of each slider, set all the others at 0.0 dB (flat), move the slider up or down, and click GRAPH.  The frequency scale is logarithmic from 10
Hz to 31.6 kHz and the dB scale automatically adjusts to encompass the boost or attenuation.

Automatic volume adjustments associated with each tone slider are included in each plot.

The frequency response plot is perfectly accurate up to 22 kHz when your sound card is set at 44.1 kHz sample rate.  At higher rates there will be a small
error at the highest frequencies.

REVERBERATION BUTTONS
BURWEN BOBCAT reverberation is very different from the many reverberation systems devised to date.  They all attempt to emulate real reverberation
that occurs when direct sound is reflected many times from the boundaries of a room or concert hall.  In real reverberation physical dimensions prevent
any significant reflections above 10 kHz.  With this in mind most electronic reverberation systems deliberately roll off the high frequency reverberation
content.

Dick Burwen discovered that the missing extreme high frequency reverberation content is what your ear really likes to hear.  In particular the thousands of
extreme high frequency reflections (mirror images of the high frequency direct sound) overcome high frequency recording imperfections and get rid of
what many people think of as annoying "digital sound".  Equalizing up the high frequencies in sampled real reverberation does not work.  The
reverberation has to be generated electronically.  Burwen spent many years perfecting over 300 different high frequency reverbs in his AUDIO
SPLENDOR mastering software. The BURWEN BOBCAT TONE BALANCER offers 3 of the most useful patented reverbs.

BASIC
This 400 millisecond reverb can be used for all types of music from rock to classical, vocals, and most speech.  It smooths the high frequencies, slightly
widens the stereo image, provides a fuller sound, but no effect on low bass.  It is the most neutral and subtle reverb, except for that used in PURE in
BURWEN BOBCAT TR which is just slightly different.

RECITAL
Add a little excitement to your music with a longer 1.5 second reverb that hints of a small hall.  It has its greatest effect at extreme high frequencies and
no effect on low bass which could become muddy.  RECITAL is useful for medium tempo music, including many vocals.

EXTREME
In Normal reverbs like BASIC and RECITAL the direct (original) signal component is larger than the reverb.  EXTREME is just the opposite.  At high
frequencies the reverb signal is bigger than the direct signal and effectively substitutes for it.  At 20 kHz the direct signal may be less than 1/50 of the
reverb.  The tonal balance has been compensated to nearly match the original.

EXTREME is most useful on classical music where it completely removes roughness, and makes the sound more live.  In two channel systems the 1
second reverb cleans up gritty sounding jazz.  In multi-channel systems EXTREME adds ambiance in the rear and side channels that lasts 3 seconds for
a glorious concert hall effect.

LEFT-RIGHT BAL
Slight mismatch between your speakers, room asymmetry, and occasional left-right unbalance in recordings necessitate this control.  It provides +/- 6 dB
left-right gain difference in 0.1 dB steps.  It is surprising how much difference only 0.1 dB (1.1%) makes.

INPUT CH - SPKRS
This switch selects any of 43 7.1 channel output mixes made from 1 to 8 channels input.  In a 2-channel stereo system only some are useful and normally
you will select 2 - 2.  This means 2 input channels produce 2 output channels to stereo speakers.  Below are the 43 switch selections

By blending the left and right channels in-phase or out-of phase, the perceived width of the stereo image is made wider or narrower than the speaker
spacing in some of the mixes.
Open BURWEN BOBCAT TR first.  It does not open from the Start Button.
  1. Open the Windows Media Player by inserting a CD or DVD in the drive or by double clicking its icon.
  2. Go to the menu item View, Plug-ins, Other, Burwen Bobcat and click to place a check mark at Burwen Bobcat.  The Burwen Bobcat
    window will open.
If the menu is not visible, in Windows Media Player 11, open the Library window and click the leftmost of two down arrows next to the search box at
upper right.  Click Show Classic Menus.  In Windows Media Player 12, open the Library window and click Organize, Layout, Show Menu Bar.

Open BURWEN BOBCAT TONE BALANCER.xls
  1. In Windows Explorer or My Computer go to C:\BURWEN BOBCAT.  Double-click the file BURWEN BOBCAT TONE BALANCER.xls.  This will open
    the workbook in Microsoft Office Excel.
  2. Zoom or size the window so the sliders are almost as tall as the screen on a 1920 x 1080 pixel display or as tall as possible while still leaving the
    buttons in the right column accessible.  View the Windows Media Player full screen.  Then use the Taskbar buttons to select either window.
  3. Play a track.  For quickest setting, click each of the 3 buttons in the BURWEN BOBCAT window of the BURWEN BOBCAT plug-in.  By listening for
    imperfections in the sound this will give you an idea of how to set the controls in the BURWEN BOBCAT TONE BALANCER.xls window to improve
    the sound.
4. Set the controls in the BURWEN BOBCAT TONE BALANCER.xls window and click PROCESS AUDIO.  
5. When you move the sliders, except for the VOLUME slider, the sound does not change until you click PROCESS AUDIO.  Your computer does not
    have even 1/100th the processing power needed for real-time operation of the controls.  An fractional-second hour-glass appears after you operate
    a control indicating calculation.  Selecting a different reverberation may require around 3 seconds for calculation of all 1,400,000 long equations.
6. Slow operation is really an advantage.  Tenths of a dB are important when the sound is near optimum balance.  They are too difficult to perceive
    unless you know the exact moment when the sound changes due to clicking PROCESS AUDIO.
THE CONTROLS
Unlike graphic equalizers the 6 TONE sliders are completely independent and non-interacting   The LOW, BASS, and MIDDLE controls boost or
attenuate low frequencies while the TREBLE, MID HIGH, and HIGH controls boost or attenuate high frequencies.  The sliders behave as either 401 or
601 position switches, providing perfectly flat response at center and +/- 20 dB or +/- 30 dB ranges in 0.1 dB steps.  Volume is automatically
compensated for each control to maintain nearly constant subjective loudness.  It is possible to boost as much as 73 dB at 15 Hz while attenuating 72 dB
at 20 kHz.

Classic bass and treble controls use a simple resistor-capacitor circuit and the boost frequency response is a mirror image of the attenuation response.  
The BURWEN BOBCAT TONE BALANCER digital controls deliberately produce more complex response curves for better sound, and boost and
attenuation curves are unsymmetrical.

LOW
This slider provides a peak or dip at 15 Hz.  At 30 dB boost 100 Hz is up only 6.5 dB.  It can add an octave to your speaker's bass response.

BASS
BASS is like a conventional shelf-type bass control with a +/- 20 dB range.  Half the boost or attenuation occurs at 120 Hz.

MIDDLE
Although operation is similar to a bass control that works higher in frequency, this slider is designed to simultaneously boost bass and attenuate high
frequencies, or the opposite.  It has a +/- 20 dB range.  At a typical setting of 3 dB boost it produces a more gradual slope in the 800 Hz region than a
simple bass-type control.

TREBLE
When attenuating high frequencies the TREBLE slider produces a faster slope than a simple shelf-type control and a little dip at 3700 Hz where many
recordings sound screechy.  Boost is a gradual shelf.  Your settings will typically be in the + 1 dB to -3 dB range.  The extreme range of +/- 20 dB is
capable of taming the most excruciating recordings so they become listenable.

MID HIGH
The MID HIGH slider has an extreme range of +/- 30 dB.  Half the boost or attenuation occurs at 5 kHz.  A few very old screechy recordings need
extreme high frequency attenuation, as much as 40 dB - that takes more than one slider.  Sometimes it is useful to push the MID HIGH slider up or down
while an adjacent slider is pushed in the opposite direction to obtain a broad dip or peak.

HIGH
The HIGH slider produces a peak at 22 kHz and has a range of +/-30 dB.  It provides the fine adjustment of highest harmonics that affect presence,
cleanliness, and width of the stereo image.

MULTI-CHANNEL OUTPUT FROM STEREO
Dick Burwen discovered more than 35 years ago that he could get better sound from 2 microphones than from 5 by processing the 2 channel signal into 5
channels.  Today with his patent pending high frequency reverberation producing ambiance in rear and side channels this is more true than ever. The front
center channel in the mixes above is made from the front left and front right inputs.  A lot of ambiance is added into all three front channels too to clean up
the sound.

The amount of direct sound fed to rear and side speakers is very small compared with the front speakers.  Reverberation is greatest at extreme high
frequencies and there is practically none at extreme low frequencies, avoiding muddy bass.  So you do not need a huge powerful amplifier-speaker
combination to reproduce music in your rear and side speakers.  It should be capable of reproducing extreme low frequencies at reduced levels.  Of
course, if you use the same system to produce explosions from movies in the rear channels, you should have a powerful system for every channel, at
least 5.

Windows XP allows 5.1-channels output.  Vista and Windows 7 allow 7.1 channels.  Unless your listening room is more than 70 feet long there is no
advantage from side speakers for music.  The mixes above have a subwoofer output mix on channel 4.  It has a bandwidth of 3,000 Hz.  So you need to
use your speaker manufacturer's low-pass filter that matches the subwoofer.

MULTI-CHANNEL MIX
The normal mix you should use for multi-channel output is 2 - ALL.  Other mixes can widen or narrow the stereo image.

REAR
Use the REAR slider to adjust the gains of the rear and side channels for best concert hall effect.  It will have some effect on the optimum tone slider
settings.  More REAR sound can make the music smoother at the expense of reduced presence.

PAGE DOWN - SETUP
By default there is nothing you have to do to set the operation of the BURWEN BOBCAT TONE BALANCER.  The only option available with BURWEN
BOBCAT TR is REMOTE CONTROL.

REMOTE CONTROL
Be sure your wired or wireless network is working.  In the address box fill in the name of your main computer and then click the REMOTE CONTROL
check box.  BURWEN BOBCAT TR must be open on your main computer and preferably closed on thiis REMOTE CONTROL computer.   Set the
controls and click PROCESS AUDIO.  BURWEN BOBCAT TONE BALANCER.xls can be open on your main computer and the computer you operate will
control the sound.  

If your network uses static IP addresses you can fill in the IP address of your main computer instead of its name.  The IP address is likely to change from
time to time if it is not static.  So it is best to fill in the main computer's name instead.

Any number of remote control computers can be used, one at a time, but your license allows installation on only two computers operated by the same one
person.

To control the sound when the Windows Media Player plays the black cell at left must say
WMP.

To control the sound when playing on this computer, uncheck REMOTE CONTROL.  It is not necessary to change the computer name to
localhost.

WMP, OFF, ANALOG
If the black cell at left does not say WMP, click the WMP button.  You can use the OFF button to mute the sound.  To restore the sound click WMP.  The
ANALOG button cannot be used with BURWEN BOBCAT TR.  It applies to BURWEN AUDIO.  These buttons determine where PROCESS AUDIO will
send your sound.

DIRECTX
Be sure this box is not checked.  It is for use with BURWEN AUDIO.  If checked with BURWEN BOBCAT TR it will prevent PROCESS AUDIO from
working.

OPERATING TIPS
  • Remember pushing up the 3 left Tone sliders boosts low frequencies.  Pushing up the 3 right sliders boosts high frequencies.
  • Nothing happens until you click PROCESS AUDIO.
  • Use all the Tone sliders, first in increments of 1 or 2 dB, finally in tenths of a dB as you perfect the sound.
  • If you push both MIDDLE and TREBLE up the same number of dB, the canceling effect produces a dip at 1400 Hz.
  • If you push BASS down and MIDDLE up an equal number of DB you will create a broad peak at 300 Hz.
  • Many recordings sound good when MID HIGH is pushed down and HIGH is up.
IN CASE OF NO EFFECT
  • Be sure BURWEN BOBCAT is open.
  • Click PROCESS AUDIO to set the address, then test for communication with the VOLUME SLIDER.
  • Page down.  Click WMP.
  • Be sure REMOTE CONTROL is not checked unless you are using it.  DIRECTX must not be checked.
  • For REMOTE CONTROL the name of the MAIN computer must show in the right hand black cell.
RIPPING, BURNING, RECORDING, CONVERTING
If you want processing to occur during any of these operations Click either Pure Bobcat or Smooth Bobcat in the BURWEN BOBCAT window.  Custom
settings are not available for these operations.  For no processing, close BURWEN BOBCAT.

We recommend ripping CDs to WMA lossless with BURWEN BOBCAT closed.
QUICK START
  • Open BURWEN BOBCAT in the Windows Media Player from View, Plug-ins, other.
  • Open C:\BURWEN BOBCAT, BURWEN BOBCAT TONE BALANCER.xls in Excel.
  • Play a track, set the Controls, and click PROCESS AUDIO.
IDENTIFYING BURWEN BOBCAT PROCESSED FILES
In the Windows media Player a file processed by Burwen Bobcat has a subtitle “BURWEN BOBCAT BC” if processed using Pure Bobcat.  It has a
subtitle "BURWEN BOBCAT SH" if processed using
Smooth.Bobcat.  Files with BURWEN BOBCAT in the subtitle (or showing the Bobcat icon in
Windows explorer) will automatically play in
Bypass.  Clicking PROCESS AUDIO will override Bypass and produce your new sound until track changes
detect another subtitle.

BURWEN BOBCAT PROCESSED FILES PLAY IN NO BOBCAT AUTOMATICALLY
Commercial CDs produced with Bobcat processing will play in Bypass if the Album name shown in the Windows Media Player contains a caret (^).  For
compilations only individual tracks will play in Bypass if the track title contains a caret (^).  To make this work the mastering engineer must insert the ^ at
the beginning of the album or track name and notifiy the internet database from which the Windows Media Player gets its album information.  CDs and
files ripped from them do not show the Bobcat icon in Windows Explorer or My Computer.  Clicking PROCESS AUDIO will override Bypass and produce
your new sound until track changes detect another ^ at the beginning if the track or album name.
MOTU 828MK3 INSTALLATION
Download and install the latest MOTU driver software for your product from the MOTU website.  Follow the on-screen prompts and select installation of
FireWire USB Drivers.  Allow restart at Finish.

SET UP THE MOTU 828MK3
Connect your audio inputs and outputs according to the following:  For single-ended systems it is OK to use mono phone plugs which short one side of the
audio output to ground.













Connect the Firewire cable.  Then power on the MOTU 828MK3 to install its driver.  If hardware detection opens a dialog box, when asked, select
“Continue Anyway”.  

Go to Start, All Programs, MOTU, MOTU Audio Console and click to open.  Set the options as below.  When using the Windows Media Player in Windows
7, if you hear stuttering, close the Player and open the MOTU AUDIO Console.  Uncheck Use WaveRT for Windows Audio.
