Important Safety Instructions
Read these instructions:
Please read all Safety and Operating instructions before connecting and operating this
product. This manual should be kept for future reference.
Verify AC Circuit Capacity Before Use:
Your new Bergantino B|AMP comes equipped with a UPS (Universal Power Supply) capable
of operating from 100 – 240VAC (~), 50/60Hz with no user adjustments or switching
necessary. The high power output of your amplifier may require heavy current draw under Full-
Load conditions. Connecting multiple amplifiers to the same circuit, or connecting the amplifier
to the same circuit used by other heavy power devices, such as high-wattage lights, may
cause circuit breakers to trip. It is always a good idea to avoid using any audio equipment on
the same AC circuit as equipment with motors, such as air conditioners or refrigerators. This
will lessen the possibility of power variation and electrical start-up noise affecting your sound.
Earth Grounding Connection:
To prevent electric shock, do not remove the grounding plug on the power cord, or use any
plug or extension cord that does not have a grounding plug provided. Make certain that the AC
outlet is properly grounded as well. Do not use an adapter plug with this product.
Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus:
To avoid safety hazards, use only the power cord supplied with your unit. We do not
recommend using an extension cord with this product. Damaged power cords should be
replaced immediately with cords meeting factory specifications. If a replacement cord is used,
make certain that it is of consistent quality and gauge as the original and is UL/IEC Certified.
When disconnecting the power cord from an AC outlet, always pull the plug, never pull the
cord. If you do not intend to use the amplifier for a considerable length of time, disconnect the
plug from the AC outlet.
Do not use this apparatus near water:
Never expose the amplifier to rain, moisture, dripping or splashing water. Do not place objects
filled with liquids on or nearby the amplifier.
Do Not Open The Amplifier Enclosure:
There are no user-serviceable components inside this product. Opening the amplifier
enclosure may present a shock hazard, and modification to the product will void your warranty.
If liquid enters the unit, or any metal object such as a piece of wire accidentally falls inside the
enclosure, disconnect the unit from the AC power source immediately and consult an
authorized service station.
Unpacking:
The carton and packing materials used in shipping your new amplifier were specially designed
to cushion it from the shocks and vibration that occur during transport. We suggest that you
save the carton and packing materials for use in shipping, in the event you move, or the
amplifier needs repair.

Speaker Profiles = Intelligent Equalization:
Having your speaker cabinet EQ’d and matched to the acoustic environment frees up your
tone controls to be creative elements, rather than being used to ‘fix’ a speaker design or a bad
acoustic space.
Cool Running = Reliability:
The B|AMP uses a Class D amplifier topology that generates less than half the heat of
conventional amplifiers. This keeps the amp running a lot cooler and makes it much more
reliable. To cool the amp when it’s being driven hard, we’ve incorporated a temperature
sensitive fan cooling system. When the amp is under a light load, the fan is off. If the amp
should reach a specified operating temperature, the micro-controller in the B|AMP will turn the
fan on automatically until it is cooled to a safe operating temperature. This type of thermal
management will ensure years of trouble free use.

Quick Start
The Bergantino Audio Systems’ B|AMP is designed to be incredibly flexible, yet simple to
operate. All controls have a well-defined purpose and are designed to be as intuitive as
possible. These directions will help take you through the basics and give you a good start for
setting up your sound, especially if you own a currently available, Bergantino speaker cabinet.
However, it is highly recommended to read on to learn all the features of the B|AMP in order to
realize all its very useful features and benefits!
1. Plug the B|AMP in:
With the power switch in the Off position, connect the supplied power cord from the amplifier
AC receptacle, to an AC power outlet of proper voltage and power rating (see safety
information for more details).
2. Connect your speaker cabinets:
Connect your speaker cabinet(s) to either of the SpeakOn outputs (these are wired in parallel
so you can use either one). Be sure not to exceed the minimum recommended speaker load.
The minimum recommended speaker loads for the B|AMP is user programmable in the
software program menus for 2-Ohm, 2.67-Ohm and 4/8-Ohm operation. The initial default
setting is 4/8-Ohm.
3. Plug in your bass:
Using an instrument cable, connect your bass to the Input jack and turn the power switch on. If
you have active tone controls on your bass, turn all of the controls to the middle or flat position
and adjust the volume to the maximum point you would normally use. If you have a passive
bass, turn all tone and volume controls all the way up.
4. Front panel control settings:
When you first turn on the B|AMP the tone controls will be set flat and no speaker profiles will
be installed. Set the Instrument Gain and Master Volumes at 0 (off).
5. Select Speaker Profile
If you’re using a currently offered Bergantino speaker model, push and hold the Prog button to
the right of the LCD display for 3 seconds to get into Program Mode. Quickly push the Prog
button 3 times to get to the Profile Select screen. Turn the Bass/Filters knob (right or left)
until your speaker model appears on the display. Once your speaker is displayed on the LCD
display you can either press and hold the Prog button for 3 seconds to get back to the home
screen, let it time out automatically after 15 seconds, or press the Mute button 2 times
consecutively. Your speaker profile is now loaded into the Profile EQ section of the B|AMP’s
DSP processor.
The screen below shows the CN212 profile being selected and loaded into the B|AMP’s Profile
EQ section.

!
6!
If you’re not using a currently offered model, you can download the Profile for many of our
older, discontinued Bergantino cabinets as well as some Bergantino cabinet combinations from
our website (www.bergantino.com) onto a FAT32 formatted thumb drive, and load it into one of
the 12 dedicated Profile memory slots via the USB port (see Profile Select menu below).
!The currently selected Profile will be loaded into the DSP profile filters
upon each recycling of power until a new one is selected.
6. Input level and Master Volume settings:
For proper operation, it is very important to adjust all gain levels properly. To adjust the Input
gain level, first turn the Master volume and Input Gain of the B|AMP all the way down (CCW).
Next, put the volume controls on your instrument at the maximum level you will be using them
at and play your bass like you normally would, including hard dynamic attacks. Gradually
increase the Input Gain control (clockwise) until the OL (overload) indicator just begins to flash.
Once flashing, reduce the Input Gain (CCW) by 1/8 of a turn for some additional headroom
before clipping.
If the OL led doesn’t come on at all with the Input gain turned all the way up, chances are
you’re either using a more traditional, single coil, low output bass, or you enjoy playing with a
lighter touch. That’s ok and perfectly normal. If this is the case, keep the input gain turned all
the way up for best S/N ratio and select Lo Output for Instrument Level in the Extended
Amplifier’s Feature section under Program Mode to compensate for overall gain.
Important!: If using an active bass and the Input gain level of the B|AMP is near or below 9:00
in order to keep the OL led from flashing, it is highly recommended you turn down the volume
on your bass, or preferably if equipped, turn the gain down on your onboard preamp. This is
very important as to not overdrive the input of the B|AMP. Some onboard preamps have
internal adjustable gain controls. If you have active/passive switching capabilities on your bass,
it is best to adjust the active gain such that it matches the passive gain with all tone controls
set flat. In other words, you want to adjust your onboard preamp to have unity gain. This will
ensure maximum headroom for you onboard preamp as well as best gain matching of your
bass to the B|AMP’s input stage.
!Remember, the purpose of an onboard preamp is to buffer the pickups from long cable
runs and to provide active tone controls for tone shaping, not to increase your overall
output level and volume. That is what your amplifier is for!
Once you’ve matched the maximum signal from your bass without overloading the input stage
of the amplifier, increase the Master volume of the B|AMP by turning the Master volume knob
in a clockwise direction to the desired level. You should be hearing your bass quite well at this
point. You should now only use the Master volume now to achieve your desired sound level.
!For clear, undistorted sound, it’s very important not to overdrive the input stage of the
B|AMP. If you increase in level any tone or volume control on your bass after adjusting
the input gain, you should check to make sure the OL indicator isn’t flashing.

Front Panel Controls and Operation
1. Aux Input:A standard 1/8” mini stereo jack to plug in an external sound source (iPod, MP3
player, etc.). The Aux Input does not go to the DI. Maximum, unclipped input level is 2Vrms.
2. Aux Gain: Gain control for the Aux input device. Adjust this knob to achieve the desired
level of your Aux Input source and to obtain the relative balance between this source and your
instrument. If the OL indicator illuminates, turn down Aux Gain level on B|AMP until it no
longer flashes. If it still flashes with level all the way down, turn level down from device
connected to Aux input and then readjust Aux Gain level.
3. Input:A 1/4” unbalanced input jack to plug in an active or passive bass into a studio quality,
high impedance, input buffer.
4. Input Gain:Gain control for the Instrument input. Adjust this level to obtain maximum input
gain before any flashing of the OL indicator occurs.
5. OL (overload) Indicator: Indicates the input stage of the B|AMP is being overdriven when
flashing yellow. If an overload condition is indicated, turn appropriate gain knob (Aux or Input)
counterclockwise to reduce gain until no flashing occurs and adjust Master volume to achieve
desired volume. Also learn more about properly adjusting the Input gain of the B|AMP in the
Instrument Level section of the Program Mode part of this manual.
6. Master (volume): This control raises and lowers the Master volume of the B|AMP.
7. Protect (indicator): Should the amp experience a fault (over heat, over current) the amp
will mute the output and this LED will turn red until the condition is corrected. Check and make
sure there are no obvious conditions causing the amp to enter protect mode such as a shorted
speaker cable or the fan or vent holes being blocked on the outside of the unit.

!
8!
8. Clip (indicator): This indicator will flash yellow when the B|AMP senses an overdriven or
clipped signal at its output. This is an indication that the amplifier is being driven beyond its
ability to produce a clean, undistorted output signal. It’s ok and normal to see the flashing of
this indicator on loud peaks. However, continuous, sustained illumination of this indicator
should be avoided.
!There are Proprietary and musical Compressor/Limiters programmed into the B|AMP’s
DSP to help prevent the B|AMP from being overdriven to a point of audible distortion.
9. LCD Display: The LCD (liquid-crystal display) display serves many functions and displays
everything from basic tone control settings (home screen) to the many levels of software based
menu screens in the B|AMP.
10. Filters/BASS Control: This control has multiple functions:
As a Tone Control, turning the control Left or Right from the home screen will decrease or
increase the level of the Bass frequencies in 1dB increments, from -9db to +9db. The level in
dB will be shown above on the LCD display.
!The screen below shows an example of the B|AMP’s home screen where the gain of all
4 tone controls can be adjusted.
If you push and hold the Filters/BASS control for 2 seconds, you will be able to adjust the
center frequencies of all 4 tone controls. The frequency range of the Bass control is from 40Hz
to 120Hz, variable in 5Hz increments. You can return to the home screen by pressing any of
the 4 tone control knobs, or if left idle for 5 seconds, the LCD display will return to the home
screen automatically.
!The screen below shows the B|AMP’s semi-parametric EQ screen after pressing and
holding any of the 4 tone controls for 2 seconds.
When the Filters/BASS control is pressed and released, it displays the filter’s screen that
includes a VHPF screen (Variable High Pass Filter) and Variable Feedback filter.

!
!
9!
The VHPF (turn Bass/Filters knob to adjust frequency) allows frequencies above the displayed
frequency to pass while cutting frequencies below. Factory default is 40Hz. Turning this knob
adjusts the cut-off frequency from 32Hz – 80Hz in 2Hz increments. Use this control to clean up
the very low end of the bass frequencies, which can often muddy the low-end program
information and needlessly stress your speaker system and waste amplifier headroom.
!To help minimize needless stress on speakers and maximize amplifier and overall
system headroom, it is advisable to set this control at 40Hz (factory default setting) or
higher, if further low frequency attenuation is needed.
The Variable Feedback filter is intuitively designed to help you identify and sweep the note
frequencies from E1 (41Hz) – G3 (196Hz) in single note (1/2 step) increments, and adjust the
gain from OFF to -6db to -12dB in level to help eliminate or minimize problem feedback issues
with electro-acoustic instruments.
To use, try to identify the note on your instrument that is feeding back the strongest from the
location in which you will be playing (very important as feedback is affected by the
proximity of the instrument to the boundaries and sound source in which it is near). While
muting your instrument or amp, press and release the filter knob and then turn the L/Mid or
H/Mid knob to the note (i.e. E1) that is feeding back the strongest. Turn the TRBL knob CCW
to set the cut level between -6db and -12db, then un-mute the amp or instrument and go back
to the same location you will be playing from and see if the feedback has been eliminated or
reduced. You may need to try this a few times and adjust the amount of cut in gain
accordingly.
"The green Filters LED indicates that either one or both of the filters are engaged.
While in the Filter screen, you can return to the home screen by pressing any of the tone
controls, or if left idle for 10 seconds, the LCD display will return to the home screen
automatically.
11. Mem1/LMID Control: This control has multiple functions:
As a Tone Control, turning the control Left or right from the home screen will decrease or
increase the level of the Lo-Mid frequencies in 1dB increments, from -9db to +9db. The level in
dB will be shown above on the LCD display.
Push and hold this control for 2 seconds, and you will be able to adjust the center frequencies
of all 4 tone controls. The frequency range of the LMID control is from 150Hz to 800Hz,
variable in 50Hz increments. You can return to the home screen by pressing any of the tone
controls, or if left idle for 5 seconds, the LCD display will return to the home screen
automatically.
If a tone setting has been previously stored in this location, when quickly pushed and released,
that tone setting will be loaded into the DSP’s tone filters, including the state of the bright

switch. (See Mem1/Mem2 Save on how to save settings to this location). Push this knob
again, and you will be taken back to the previous home screen.
12. Mem2/HMID Control: This control has multiple functions:
As a Tone Control, turning the control Left or Right from the home screen will decrease or
increase the level of the High-Mid frequencies in 1dB increments, from -9db to +9db. The level
in dB will be shown above on the LCD display.
Push and hold this control for 2 seconds, and you will be able to adjust the center frequencies
of all 4 tone controls. The frequency range of the HMID control is from 800Hz to 3kHz, variable
in 100Hz increments. You can return to the home screen by pressing any of the tone controls,
or if left idle for 5 seconds, the LCD display will return to the home screen automatically.
If a tone setting has been previously stored in this location, when quickly pushed and released,
that tone setting will be loaded into the DSP’s tone filters, including the state of the bright
switch. (See Mem1/Mem2 Save on how to save settings to this location). Push this knob
again, and you will be taken back to the previous home screen.
13. Bright/TRBL Control:This control has multiple functions:
As a Tone Control, turning the control Left or Right from the home screen will decrease or
increase the level of the Treble frequencies in 1dB increments, from -9db to +9db. The level in
dB will be shown above on the LCD display.
If you push and hold this control for 2 seconds, you will be able to adjust the center
frequencies of all 4 tone controls. The frequency range of the TRBL control is from 3kHz to
9kHz, variable in 500Hz increments. You can return to the home screen by pressing any of the
tone controls, or if left idle for 5 seconds, the LCD display will return to the home screen
automatically.
When this control is quickly pressed and released, it activates the Bright filter. Use this control
to add some sparkle or snap to your final tonal contour. (See Bright Adjust Menu in Program
Mode on how to program the frequency and gain of this filter)
14. Prog (Program Button): From the Home Screen, press and hold the Prog button for 3
seconds to enter Program Mode. The green Prog LED will illuminate (See Program Mode).
Or while pressing and holding the Prog button, press Mem1 or Mem2 to save a tone setting in
that location (See Mem1/Mem2 Save in Extended Amplifier Features).
15. Mute: When Mute is engaged, the red Mute LED will illuminate and the amplifier’s Main
output, DI output, and Line output (except when tuner is selected for the Line out) will be
muted.
If the B|AMP’s tuner is disabled (see Tuner section in Program Mode), the following screen
will be shown on the LCD display.

!
!
11!
If the B|AMP’s tuner is enabled, a fully digital chromatic tuner is activated and displayed on the
LCD display.
The first screen indicates there is no signal detected by the B|AMP’s tuner. The second
screen indicates a properly tuned A1 string. The third and fourth screens show a sharp F#2
and a flat G2 respectively.
16. USB Port: This port will support a FAT32 formatted thumb drive to load speaker profiles
into program memory and also perform firmware updates when or if they become available.
!WARNING!!! The USB port is not designed or intended for charging USB devices
such as cell phones, ipods, etc. Plugging in any device other than a thumb drive could
adversely affect the operation of the B|AMP.

10: Cooling Fan: The onboard microcontroller monitors the amplifier temperature and
engages the cooling fan when needed to reduce the amplifier temperature. The fan can be
turned from Auto to On in Program Mode for extreme usage conditions.
Note: The fan is automatically set to Auto upon each power recycle.
Extended Amplifier Features
Mem1/Mem2 Save
You can save and store 2 independent tone settings in memory for future recall. The
parameters that are saved are the BASS, LMID, HMID, TRBL (center frequency and gain), and
Bright settings.
Once you’ve determined the tone setting you want to save, while pressing and holding the
Prog button, press the desired Mem location where you would like to store that tone setting
(Mem1 or Mem2). The green LED over that memory location will illuminate indicating the tone
setting is now saved in that memory location.
To recall these setting at a later time, just push the appropriate Mem control knob and release.
The saved settings will now be loaded into the DSP and the green LED will illuminate. To go
back to the previous home screen, just push the same Memory control knob again.
Program Mode
Most of the B|AMP’s extended and unique features are accessed in the Program Mode. To
enter program mode, from the Home Screen, press and hold the Prog button for 3 seconds.
The green Prog LED will turn on and the first menu screen will appear on the LCD display
(Instrument Level Menu). The green Prog LED will stay on for the duration of the time you’re
in program mode. By quickly pressing and releasing the Prog button while in program mode,
you will be able to cycle through the various program menus until you reach the desired menu.
To leave program mode and go back to the Home Screen, press and hold the Prog button
again for 3 seconds, or the Program Mode will eventually time out to the home screen after 15
seconds of no activity. You can also press Mute 2 times to quickly return to the Home
Screen.
Screen 1 – Instrument Level
This menu allows you to select between using a Hi Output instrument (> 0.3 Volts) and a Lo
Output instrument (< 0.3V). When Lo Output is selected, an increase in gain is programmed
into the B|AMP to compensate.
Turn the Bass/Filters Knob to select the desired Instrument output level:
Hi Output #Lo Output
!Note: Some active basses may have outputs comparable to a single coil, passive bass
while some passive basses may have outputs comparable to a more traditional active
bass. Be sure to select Instrument Level accordingly.

!
14!
Properly Adjusting Input Gain
If using an active bass, start in Hi Output mode (Factory default setting), and with the input
gain fully off, play your bass like you normally would, including hard dynamic attacks.
Gradually turn the input gain up until you can see the OL led flash on the front panel of the
B|AMP. Once the OL led flashes, back off the knob 1/8 of a turn for additional headroom
before clipping. This is the optimal input level for your bass and playing style. Keep the
Instrument Level in Hi Output mode for this instrument.
If you can’t get the OL led to flash when the input gain is turned all the way up, that’s ok.
Leave the input gain turned all the way up and select Lo Output for Instrument Level and re-
adjust Master volume accordingly.
If using a passive instrument, start in Hi Output mode also and follow procedure described
above. If the OL led flashes under your normal playing conditions, stay in Hi Output mode. If
not, select Lo Output for Instrument Level, keeping the Input gain turned all the way up.
!For best S/N ration, when Lo Output mode is necessary, the instrument gain should
be turned all the way up.
!If the OL indicator flashes before reaching 9:00 on the Input gain knob, turn the
volume down on your bass, or, if your bass has a gain adjustment on its onboard
preamp, turn that gain down instead. Failure to do so could allow the input stage of the
B|AMP to be overdriven, limiting the dynamic range of your signal and creating
unnecessary distortion. In addition, if the output of your active bass is too hot, you
could unnecessarily and unknowingly be clipping your onboard preamp, introducing a
distorted signal to your amplification system right out of the gate! Try to adjust your
bass’ active output level to be the same as its passive level to ensure maximum
dynamic range and headroom before clipping. Remember, if your overall gain is set
too high, boosting any of your tone controls could easily clip your overall signal at the
output of your onboard preamp!
Screen 2 – DI Select menu
This menu allows you to select whether the Pre EQ or Post EQ signal is sent to the DI output.
•Turn the Bass/Filters Knob to select DI Output:

!
!
15!
Pre-EQ #Post- EQ
Pre-EQ: This signal includes input gain and effects loop, but no tone controls
Post-EQ: This signal includes input gain, effects loop and tone controls.
!The B|AMP’s Profile EQ section will never go to the DI!output, thus never to the FOH
system. This is an important feature of the B|AMP’s architecture, as it allows the
profiles to properly EQ your stage system without interfering with the FOH system.
Your Post EQ DI contains only your tone adjustments, not your speaker EQ!
Screen 3 – Bright Filter Adjust Menu
This menu allows you to adjust the center frequency and gain parameters of the Bright filter.
When the bright function is engaged from the home screen by pushing the Bright control knob,
the parameters you adjust in this menu will be loaded into the DSP’s Bright filter.
!Be sure to engage the Bright function while in the Home Screen before entering
program mode so you can test the results of your adjustments in real time while in this
screen.
•Turn the Bass/Filters knob to adjust frequency from 2kHz to 10kHz in
increments of 500Hz.
•Turn the Trbl/Bright knob to adjust gain in increments of 1dB from +3dB
to +12dB.
Below shows the Bright filter adjusted to a center frequency of 4.5khz and a gain of +6db.
Whenever the Bright function is engaged from the home screen, these parameters will be
loaded into the B|AMP’s Bright filter EQ.
Screen 4 – Profile Select
This menu allows you to select one of the B|AMP’s stored speaker Profiles and load it into the
Profile EQ section of the B|AMP’s DSP processor.
Turn the Bass/Filters knob (Left or Right) until the desired Profile appears on the LCD display.
Once displayed, the selected profile will be loaded into the Profile EQ section of the B|AMP’s
DSP processor. The following screen shows the CN212 profile being selected and loaded into
the B|AMP’s Profile EQ section.

!
16!
Screen 5 – Profile USB Load
This menu allows you to load new profiles, via the B|AMP’s USB port, from a FAT32 formatted
thumb drive into one of the twelve dedicated Profile memory locations of the B|AMP. In this
menu, the B|AMP will read any file off the thumb drive with a .PRF extension. You will be able
to scan and select which speaker profile you would like to import from the thumb drive and
choose which dedicated profile memory location you would like to store it in for future recall.
You can also overwrite any currently saved profile with a new one. Once stored and power is
recycled, you will be able to load this new profile into the DSP’s profile filters from the Profile
Select menu above.
To load speaker Profiles:
•Insert thumb drive loaded with .prf files into B|AMP’S USB port
•Turn the Bass/Filters knob to select Profile on your USB thumb Drive
you want to store in memory
•Turn the Treble/Bright knob to select which memory location to store
the profile
•Press any knob to Store Profile.
The first screen below shows the software prompting the user to insert a USB thumb drive into
the B|AMP’s USB port in order to load a new speaker Profile (*.PRF file). The second screen
shows the CN212 profile being loaded into memory slot 3 of the B|AMP’s profile memory.
!Once loaded into one of the twelve B|AMP’s Profile memory slots, the new
speaker profile can be loaded into the B|AMP’s Profile EQ filters from the Profile
Select menu above.
!Important! After loading Profiles and removing thumb drive from USB port,
you must recycle power.
Screen 6 – Line out Select
This menu allows you to select which signal is routed to the line out jack on the back of the
B|AMP. You have 2 choices, the preamp out signal (which is post Master volume), or tuner
out, which will allow you to hook up your own tuner to the Line out jack and receive an
unprocessed signal from the input stage of the B|AMP.

•Turn Bass/Filters Knob to select Line out
Pre-Out #Tuner
Note: If Tuner is selected, this output will not be muted when the B|AMP’S Mute function is
engaged, allowing music signal to pass to a user supplied tuner during system muting. If Pre-
Out is selected, this output will be muted along with the B|AMP’s Main and DI outputs.
Screen 7 – Speaker Impedance Select
This menu allows you to condition your B|AMP to be safely used with various speaker loads. It
can select between 4/8-Ohm, 2.67-Ohm and 2-Ohm loads. The 4/8-Ohm setting is the
default setting and should be used for both 4-Ohm and 8-ohm speaker loads.
**Warning! Selecting an impedance higher than the one plugged into the B|AMP can allow
the amp to enter protect mode, reducing the output level of the amp or muting the output all
together until the underlying condition is rectified.
!Conversely, selecting an impedance lower than the one plugged into the B|AMP will
limit you from utilizing the B|AMP’s full power capabilities.
Be sure to calculate your speaker impedances properly!
4-Ohm = 1 x 4-Ohm or 2 x 8-Ohm;
2.67-Ohm = 1 x 8-Ohm +1 x 4-Ohm or 3 x 8-Ohm;
2-Ohm = 2 x 4-Ohm or 4 x 8-Ohm
•Turn Bass/Filters knob to select desired Impedance
4/8-Ohm #2.67-Ohm #2-Ohm
!Below are three screens indicating the impedance options of the B|AMP.
!When 2-Ohm operation is selected, the fan is automatically engaged.

Screen 8- Main Phase Menu
This menu allows you to reverse the phase of the main amplifier’s output (including pre-out, if
selected as the line out) to help eliminate any possible feedback or phasing issues
experienced in a live or recording environment. It does not affect the phase of the DI out.
•Turning the Bass/Filters knob
Normal #Reverse
Screen 9 – Tuner Frequency, Instrument Select and Enable Menu
This menu allows you to choose the A4 reference frequency for instrument tunings. Ranges
from A432 – A448 can be selected using the BASS/Filters knob.
It also allows you to optimize the tuner’s speed and accuracy for either Bass or Guitar by
turning the LMID/Mem1 knob to the desired instrument. And, you can enable or disable the
tuner function in this menu by turning the TRBL/Bright knob to the desired selection. If
enabled, when Mute is engaged, the LCD display will turn into a very fast and accurate
chromatic tuner optimized for the instrument selected.
The factory default is A=440.

Screen 10 – Fan Menu
This menu allows you to select Auto or On for fan control. Although not recommended, it can
be useful if you’re playing an outside venue in direct sunlight such that the case temperatures
can get unusually warm just by the effects of the direct sun. Turning the fan on will keep air
circulating through the case minimizing any heating issues under these extreme conditions.
Auto only turns the fan on when a specified temperature is reached and is the default setting.
It will be selected automatically upon power up.
