BASS V-AMP/BASS V-AMP PRO

2. CONTROL ELEMENTS

Compressor: The compressor control regulates the

attack time when the TAP key is kept pressed (see

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.

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.
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.
When an effect is selected using the EFFECTS control

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)

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.
The connector labeled INPUT is the 1/4" TS jack input of

the BASS V-AMP/BASS V-AMP PRO, which is where an

electric bass, an acoustic guitar, a keyboard etc. can be

connected. Use a common 1/4" mono jack cable for this

purpose.
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,

) is routed to the processor (par-

ticularly useful for keyboards).
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.

You can insert external effects into the serial insert loop

featured on the 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

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.
The stereo signal of the BASS V-AMP PRO without analog

speaker simulations can be taken at the ANALOG LINE

OUTPUTS. For example, this is how you connect an

external stage amp when performing live.
The POST DSP INSERT RETURN (IN) stereo jack pair is

used for connecting to the outputs of your external stereo

effects processor. The signal taken at the POST DSP SEND

(OUT) outputs

is brought back into these jacks.

The ground connection on the DI OUT outputs

can be

interrupted with the GROUND LIFT switch. This way,

rumble noise and ground loops can be avoided.
