Operating Instructions
Setting Value
The value “4.0” flashes on the display
but rotating the knob from the “3
o’clock” position to the “11 o’clock”
position does not change anything.As the knob goes past the “11
o’clock” position and its position
matches that of the value, the
value will then stop flashing and
start changing according to the
knob’s position.
Storing and Recalling Patches
After creating a sound that you like, you can store its settings in the
unit’s internal memory. Sound setting data (individual knob settings) is
called a Patch. Saving a patch to the unit’s internal memory is called
Store.
The BBT500H provides five memory locations for storing patch data.
Patch data in the memory is stored even when the power is switched
OFF, and can be recalled at any time by pressing the patch’s corre-
sponding switch. Take note that unless the changes are saved to memory,
any changes made to the patch will be lost when another patch is se-
lected or when the power is switched OFF.
Storing a Patch
After creating a sound you want to keep for later use, press and hold
any one of the Memory Switches (1-5) until all of the front panel indica-
tors light.
Ex.) Press and hold Memory Switch [1] until all indicators light.
* INPUT LEVEL and OUTPUT LEVEL settings are not stored in memory.
Recalling a Patch
To use one of the patches stored in memory, just press the Memory
Switch [1]-[5] to which the data is stored.
The indicator of the selected Memory Switch lights.
Ex.) Recalling the patch stored to Memory Switch [2].
Knob Position and Settings
When a patch is recalled from memory, etc., it may be that the
knob’s actual position differs from the value set in the recalled
patch.
In this case, the BBT500H is programmed to flash the patch’s
value on the display without changing it or the sound until the
knob’s position corresponds to the value in the recalled patch
setting.
If the display flashes when rotating the knob, continue rotating
the knob until its position matches the flashing value. When the
position and value match, the value will stop flashing on the
display and change as the knob is turned.
Ex.) If the GAIN knob is pointing at the “3 o’clock” posi-
tion and a patch with a GAIN setting of 4.0 is recalled.
After you recall or store a patch, the value for each knob will appear in
the display when the knob (COMP - TREBLE) is used.However, if the value set in the patch is different than the knob’s actual
position, the patch’s value will flash in the display but it will not change,
nor will the sound, even though you are turning the knob. For more infor-
mation on this situation, refer to the “Knob Position and Settings” sec-
tion below.
The Useful “Undo” Function
Press and hold the [MANUAL] switch activates the “Undo” func-
tion, which returns settings to the condition they were in prior to
pressing a Memory Switch [1]-[5] or the [MANUAL] switch.
This function is useful in cases such as:
Yo u’ve just made some changes to the patch saved in Memory
Switch [1] but pressed Memory Switch [2] before you could save
the changes to memory. Press and hold the [MANUAL] switch to
return the settings to the same condition they were in before you
pressed Memory Switch [2].
In the same manner, you made some changes to a patch but
pressed the [MANUAL] switch before you could save those
changes to memory. Press and hold the [MANUAL] button to re-
store your changes. 
						

							12
The BBT500H also features more precise settings for defining the fre-
quencies for each of the Tone Control knobs, operating the Compressor
and Noise Gate, or setting the Blend Level of the effect loop, etc.
To access these settings, press the [FUNCTION] switch and use the
four Modes described below.
•Amp Mode
In this mode, each knob functions in the manner it is labeled on the
front panel.
•Equalizer Mode
This mode is used to set the 1-band parametric equalizer and the
center frequency for each of the Tone Controls (Bass – Treble).
•Compressor Mode
This mode is used to set the Compressor’s blend level, noise gate
level, and effect loop.
•Utility Mode
This mode is used to set the crossover filter, and individual MIDI
settings.
Individual settings in the Amp Mode, Equalizer Mode, and Compressor
Mode are saved when patch data is saved to the unit’s memory.
Individual parameter settings in the Equalizer Mode and Compressor
Mode are set to their default values when the power is switched ON.
Individual settings in the Utility Mode are saved when exiting the Utility
Mode, and they are retained even if the power is switched OFF.
Detailed Parameter Settings
Amp Mode
Each knob functions in the manner it is labeled on the panel.
In the Amp Mode, the knob’s value (or patch’s setting value) is shown
on the display when the knob is turned.
* After the BBT500H’s power is switched ON or the [MANUAL] switch is
pressed, nothing is shown in the display until a Memory is recalled, or a
mode other than the Amp Mode is selected.
Enter the Amp Mode using one of the following methods.
•The Amp Mode is the default mode when the BBT500’s power is
switched ON.
•Press the [MANUAL] Switch to enter the Amp Mode.
•Press a Memory Switch [1] – [5] to recall a patch. Or, press and
hold a Memory Switch to save a patch to memory.
•In the Equalizer, Compressor, or Utility Mode, press the [FUNC-
TION] switch.
How Knobs Function in the Amp Mode
The knob’s value is shown on the display
when the knob is turned.

Compressor Mode
The Compressor Mode provides settings for the Compressor, Noise Gate,
and Blend Level for the effect loop.
To enter the Compressor Mode, press and hold the [FUNCTION] switch
until the knob functions are displayed in the upper row of the panel dis-
play above the knobs (the row above that used by the Equalizer Mode).
How Knobs Function in the Compressor
Mode
qINPUT LEVEL: Sets the Input Level
wSOUND TYPE: No function.
eCOMP (RATIO): Compression ratio (1.0 - ∞, 16 steps) *operates the same
as COMP in the Amp Mode.
rGAIN (THRSLD): Compressor threshold level (-54dB to 0dB, 1dB step)
Sets the signal level from which the compressor will activate. Compres-
sion is applied to signals that exceed this level.
tMASTER (ATTACK): Compressor attack time (0msec to 120msec, 1msec
step).
Sets the amount of time required for application of the compressor from
the time the signal exceeds the threshold. When a slow attack time is set,
the beginning of the attack will not be compressed.
yBASS (RELEASE): Compressor release time (5msec to 42.3 sec, 160
steps).
Sets the amount of time required for the compressor to switch off after the
signal goes below the threshold level. This smoothes gain changes to
keep the sound natural.
uLOW MID (C. GAIN): Compressor gain (0dB to 18dB, 0.1dB step)
This parameter works in conjunction with the compressor ratio setting
which is set with the 
e COMP (RATIO) control knob. In other words, gain
is automatically adjusted along with amount of compression applied to
the signal. If the Ratio = “1.0”, Gain = “0”. If the Ratio = “∞”, Gain = the
setting determined with the control knob.
iMIDDLE (KNEE): Compressor knee (Hd (Hard), 1, 2, 3, 4, 5)
Sets the depth of signal compression after the input signal exceeds the
threshold level. When set to Hd (hard), compression starts soon with the
ratio you have set. However, when set to 1-5, compression startup is
gradual, creating a more natural sound (soft knee compression).
oHIGH MID (N. GATE): Noise gate threshold level (OFF, -53dB to 0dB,
1dB step)
When the input signal’s level falls below this set level, the noise gate acti-
vates cutting off the signal.
!0TREBLE (BLEND): Blend level between the effect loop’s RETURN signal
and the dry signal (the sound created in the BBT500H) (0% (Return 0%,
Dry 100%) to 100% (Return 100%, Dry 0%)).

Individual MIDI
Settings
Crossover Filter
By connecting two BBT500Hs as shown in the illustration below, you
can create a bi-amplified system, where one amplifier is used to drive
high frequencies and a second amplifier drives low. This system uses
the amplifier’s onboard crossover filter (LPF or HPF) to determine the
range of frequencies that each amplifier will deliver.
Setting the Crossover Filter
1 Press and hold the [FUNCTION] switch for more than three sec-
onds (until “utL” appears on the display) to enter the Utility
Mode.
2 Rotate the COMP knob to set the Crossover filter’s cutoff fre-
quency.
* Range of cutoff frequencyL10 (LPF 100Hz) to L00 (LPF 1000Hz), byP (Bypass),
h10 (HPF 100Hz) to h00 (HPF 1000Hz), 93 steps
When using a bi-amplified system, make sure
that the INPUT LEVEL control knob on the
second BBT500H is set to its minimum level.
Ex.) Operating a bi-amplified system in which the crossover fil-
ter on the first amplifier is set to h50 (HPF 500Hz) to pro-
duce high frequencies, and the crossover filter on the sec-
ond amplifier is set to L50 (LPF 500Hz) to produce low fre-
quencies.

Detailed Parameter Settings
MIDI Settings
The BBT500H is MIDI* compatible and equipped with MIDI IN and MIDI
OUT jacks.
* What is MIDI?
The acronym for Musical Instruments Digital Interface, MIDI is a world-
wide standard communication interface that allows MIDI compatible mu-
sical instruments, computers, and other MIDI devices to share musical
information and control one another regardless of instrument type or
maker.
With MIDI functions you can do things like select a patch from the
BBT500H’s memory using an external MIDI device like the MFC10
Yamaha MIDI Foot Controller, etc. You can also backup data by sending
the contents in the unit’s memory to a device that is capable of saving
MIDI data (Yamaha MDF3, etc.).
Selecting a Patch with MIDI
1 Using a MIDI cable, connect the MIDI IN jack on the BBT500H to
the MIDI OUT jack on the external MIDI device.
* Use only a standard MIDI cable that is less than 15 meters in length. Use
of a longer cable can result in trouble such as abnormal operation, etc.

2 Set the MIDI receive channel on the BBT500H and the MIDI trans-
mit channel on the external device to the same MIDI channel.
(Default channel: 1)
* MIDI data can not be transmitted or received if the MIDI channels are
not properly matched.
2-1 Press and hold the [FUNCTION] switch for more than three
seconds (until “utL” appears on the display) to enter the
Utility Mode.

→ Program Change No: Memory No = 1:1, 2:2, 3:3, 4:4,
5:5, 6:1, 7:2, 8:3 …)
* What is a Program Change Map?
A Program Change Map assigns a program change number (re-
ceived via MIDI) to a memory number. For example, when the
BBT500H receives “Program Change Number 1” from an external
MIDI device, it will recall memory number “3”. This is also called a
Program Change Table.
3-1 Press and hold the [FUNCTION] switch for more than 3 sec-
onds (until “
utL” appears on the display) to enter the Utility
Mode.
3-2 While holding the [MANUAL] switch, press Memory Switch [1].
The currently assigned MIDI program change number appears
on the display (after a few seconds, the display will return to
“
utL”).
3-3 Use Memory Switches [1] and [2] to set the program change
number (1-128) that is received by the BBT500H.
Use Memory Switch [2] to increase the value and Memory
Switch [1] to decrease the value.
3-4 While holding the [MANUAL] switch, press Memory Switch [2].
The memory number that will be recalled when the program
change number that was set in step 3-3, appears on the dis-
play. (After a few seconds, the display will return to “
utL”).
3-5 Use Memory Switches [1] and [2] to set the memory number
(1-5) that corresponds to the program change number re-
ceived by the BBT500H.

Switch [1] to decrease the value.
3-6 If necessary, repeat steps 3-2 through 3-5.
3-7 Press the [FUNCTION] switch to enter the Amp Mode.
4 Now, when a program change number transmitted from an ex-
ternal MIDI device is received by the BBT500H, it will recall the
corresponding memory number that is set in the program
change map you just created will be recalled.
* Refer to the Owner’s Manual that came with your MIDI device on how
to receive or transmit program change data.

About MIDI Control Changes
You can control the overall volume of the BBT500H by con-
necting an external MIDI device’s MIDI OUT jack to the
BBT500H’s MIDI IN jack, and transmit Number 7 Control
Change Messages (Main Volume) to the BBT500H.
* With the exception of the Number 7 Control Change, the BBT500H
does not recognize any other MIDI Control Change messages.
* The Main Volume data will not change, even if a different memory
number is selected.
* When the POWER is switched ON, the Main Volume data is set
to its MAX value.
*
After the Main Volume data is changed, and the external MIDI device
is disconnected, the pre-amp’s volume level may not be sufficient. If
this case occurs, transmit a Control Change with a higher volume
setting again, or switch the POWER OFF and then back ON.
About MIDI Bulk In
Using a MIDI cable, connect the MIDI IN jack on the BBT500H
to the MIDI OUT jack on an external MIDI device to return data
that has been stored on the external device, to the BBT500H’s
memory. This operation is referred to as MIDI Bulk In.
* The device number becomes the MIDI receive channel number
(→ pg. 15). When the MIDI receive channel is set to “ALL” (Omni
ON), the channel is set to 1. When set to “oFF” (OFF) data will
not be received.
* “Ld” appears on the display while receiving MIDI Bulk data.
