7 BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual
(12) DISPLAY shows the selected eects bank and gives information about the
changes occurring while editing. When the tuner is enabled, the display
shows the tuning of the connected instrument. When one of the amp
simulations numbered 17 - 32 is selected, the LED located in the lower left
corner of the DISPLAY lights up.
The display on the BASS V-AMP PRO gives additional information about
the digital format and the sample rate of the unit, and indicates that
the BASSV-AMP PRO should be synchronized to an external wordclock
signal. Connec-ted input signals are displayed with the green SIGNAL LED;
distortedsignals are marked with the red CLIP LED.

(13) The EFFECTS control lets you select an eects preset or a combination of
several eects. This continuously turnable control is surrounded by a circle of
16 LEDs. Each eect has a corresponding LED.
(14) The COMPRESSOR control lets you compress or limit your sound. Whenyou
turn the COMPRESSOR control as far left as possible without triggering
o a LED, the dynamic characteristics of the signal are not changed.
Thecompressor on the BASS V-AMP/BASS V-AMP PRO controls two
important functions:
• You set the compression sensitivity by turning the COMPRESSOR control.
Themore you turn the control, the more pronounced the compression.
Whenthe last LED lights up while turning the control to the right, the eect
acts as a limiter.
• Turning the COMPRESSOR control while keeping the TAP key pressed lets you
set the attack parameter of the com-pressor.
◊ More detailed information about how a compressor works can be found
in chapter 5.3.
(15) When an eect is selected using the EFFECTS control (13), the proportion
with which this eect inuences the entire sound is regulated using
theEFFECTS MIX control. As long as no LED lights up while turning the
control leftwards, no eect is mixed in. This is also called an eect bypass,
and mutes all eects accross the board.
◊ When the TAP key is kept pressed, a second effects parameter can be
regulated using the EFFECTS control (see tables 6.1 and 6.2).
(16) The MASTER control regulates the overall volume of your BASS V-AMP/
BASSV-AMP PRO.
◊ In addition to the AUX LEVEL control on the BASS V-AMP, this is the
only non-programmable control of the BASS V-AMP/BASS V-AMP PRO.
All additional controls are infinitely turnable, and their positions can
be saved in a preset.
◊ The LED circles surrounding the VOLUME, BASS, MID, TREBLE, GAIN,
EFFECTS MIX and COMPRESSOR controls each have nine LEDs. Either one
LED or two adjacent LEDs light up in each LED circle at any one time.
This occurs when the control is in an in-between position. This way,
a total of 17 positions can be displayed.
(17) The connector labeled INPUT is the ¼" TS jack input of the BASS V-AMP/
BASSV-AMP PRO, which is where an electric bass, an acoustic guitar,
akeyboard etc. can be connected. Use a common 1/4” mono jack cable
forthispurpose.
(18) The LINE IN switch regulates which signal source of the BASS V-AMP PRO
is processed. When the switch is not pressed, this refers to the the signal
connected to the input connector (e.g. electric bass). When the switch is
depressed, the line signal connected to the PRE DSP INSERT (LINE IN, (20))
isrouted to the processor (par-ticularly useful for keyboards).
(19) You can connect standard headphones to the PHONES connector of your
BASS V-AMP/BASS V-AMP PRO.
◊ When headphones are connected to your BASS V-AMP/BASS V-AMP
PRO, studio mode 1 (S1) is automatically activated. If you opted not
to select a loudspeaker type in your setup and then connect a set of
headphones, your BASS V-AMP/BASS V-AMP PRO automatically selects
a speaker simulation. This improves the subjective listening impression
while using headphones. To look up which speaker simulation is paired
to which amp, please see table 5.1. However, you can deactivate a
simulation while listening to headphones by selecting “-” in CABINETS
mode. Conversely, it is possible to freely select the global output
configuration when a set of headphones is connected, so that you can
for example check the effect various modes have on your sound.

(20) You can insert external eects into the serial insert loop featured on the
BASS V-AMP PRO. The SEND/LINE OUT connector is connected to the input
of your eects unit for this purpose. The SEND/LINE OUT output is tapped
into directly before the digital signal processor (PRE DSP). This connector is
therefore ideal for recording “dry” signals (i.e. without the eects portion).
Please connect the RETURN/LINE IN connector with the output of your
external eects processor or recorder.
◊ When using the serial insert loop, please make sure that your effects
processor is not set to 100% effect signal (“wet”), because otherwise
the direct signal is missing.
◊ Pressing the LINE IN switch (22) routes the signal connected to the
RETURN/LINE IN connector to your BASS V-AMP PRO. This function may
be of use when for example listening to a “dry” recording of a guitar
signal on your BASS V-AMP PRO before running it through the effects.
(21) The stereo signal of the BASS V-AMP PRO without analog speaker
simulations can be taken at the ANALOG LINE OUTPUTS. For example,
thisis how you connect an external stage amp when performing live.
(22) The POST DSP INSERT RETURN (IN) stereo jack pair is used for connecting
to the outputs of your external stereo eects processor. Thesignal taken at
the POST DSP SEND (OUT) outputs (25) is brought back into these jacks.
(23) The ground connection on the DI OUT outputs (24) can be interrupted
with the GROUND LIFT switch. This way, rumble noise and ground loops
can beavoided. The ground connection is interrupted when the switch is
depressed (LIFT).
