BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual
(12) DISPLAY shows the selected effects 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 BASS V-AMP PRO should be synchronized to an external wordclock
signal. Connec-ted input signals are displayed with the green SIGNAL LED;
distorted signals are marked with the red CLIP LED.

(13) The EFFECTS control lets you select an effects preset or a combination of
several effects. This continuously turnable control is surrounded by a circle of
16 LEDs. Each effect has a corresponding LED.
(14) The COMPRESSOR control lets you compress or limit your sound. When you
turn the COMPRESSOR control as far left as possible without triggering
off a LED, the dynamic characteristics of the signal are not changed.
The compressor on the BASS V-AMP/BASS V-AMP PRO controls two
important functions:
• You set the compression sensitivity by turning the COMPRESSOR control.
The more you turn the control, the more pronounced the compression.
When the last LED lights up while turning the control to the right, the effect
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 effect is selected using the EFFECTS control (13) , the proportion
with which this effect influences the entire sound is regulated using
the EFFECTS MIX control. As long as no LED lights up while turning the
control leftwards, no effect is mixed in. This is also called an effect bypass,
and mutes all effects 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/
BASS V-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.

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) )
is routed to the processor (par-ticularly useful for keyboards).
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.
BASS V-AMP PRO. The SEND/LINE OUT connector is connected to the input
of your effects 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 effects portion).
Please connect the RETURN/LINE IN connector with the output of your
external effects 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.

this is how you connect an external stage amp when performing live.
to the outputs of your external stereo effects processor. The signal taken at
the POST DSP SEND (OUT) outputs (25) is brought back into these jacks.
with the GROUND LIFT switch. This way, rumble noise and ground loops
can be avoided. The ground connection is interrupted when the switch is
depressed (LIFT).
