Behringer Virtual Amplification Bass V-AMP Manuel D’Utilisation

BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual

6.3.3  Special effects
VCF+FLANGER: The combination of filter and flanger effect.
VOICE BOX: This vocal simulation fades between various vowels (a/e, a/i, a/o etc.) 

by using a LFO (Low-Frequency Oscillator). You can control this effect via a MIDI 

foot controller.
ULTRABASS: A very low bass sound that lies an entire octave beneath the lowest 

bass frequency present in the mix is currently very popular. However, this sound 

can often only be created at the studio because most bass amplifiers have no 

subharmonic function. The ULTRABASS processor, which has also found home in 

various BEHRINGER bass amps, makes creating this effect a no-brainer. You will 

be amazed how ultra-low the sounds created with the ULTRABASS function are.

6.3.4  Virtual analog bass synth
SYNTH: This effect gives you a rad three-voice synthie bass and has many 

parameters that are pre-configured in 9 variants and can be selected via TAP and 

EFFECT. The TAP key can be used to control the envelope (ADSR) of the synthie 

sounds (short tap = short tone, slow tapping = long tone). Additionally, there is 

an “intelligent” envelope follower based on key and interval, whereas the 

VCO 1 (Voltage Controlled Oscillator) is set up for specific intervals, and the 

BASS V-AMP/BASS V-AMP PRO produces bass overtones that match the particular 

key. The EFFECTS control regulates the ratio between the bass synthie and the 

bass signal with all amp and cabinet combinations.
MIDI SYNTH: The absolute highlight of your BASS V-AMP/BASS V-AMP PRO is 

our MIDI SYNTH: With 40 parameters (already described), it offers you the best 

possible sound. You get a virtual analog MIDI synthesizer equipped with powerful 

features. It is ideal for hardware and software sequencers, keyboards and for 

live applications. By using the EFFECTS control, you can mix the completely 

modelled instrument signal (EFFECT min. = modelled instrument signal only, 

EFFECT max. = bass synth only). 
We equipped the MIDI synthesizer with a complete reverb section as an 

additional feature. Of course, you can access this section via MIDI.
ROTARY CAB.: A simulation of a classic organ effect that is normally achieved 

with a terribly heavy casing and slowly or quickly rotating speakers. The physical 

principle of the Doppler effect is used to modulate the signal.

The integrated tuner is activated by pressing the TUNER key.

The chromatic tuner automatically recognizes the frequencies of all the standard 

bass notes. When you connect your instrument to the BASS V-AMP/BASS V-AMP 

PRO and strike a string, the tuner tries to recognize the tone and shows it in 

the display. Because the tuner functions chromatically, it can also recognize 

semitones. These are shown in the display with a “b” accompanying the value.
However, it may be the case that that a played note (shown in the display as 

for example “a”) slightly deviates from the ideal tone. This will be indicated by 

lighting up at least one of the four arrow LEDs at the lower edge of the display. 

When the note played lies between the deviations shown by means of the 

individual LEDs, two LEDs may light up. If the circular middle tuner LED lights up, 

the played note is identical to the note shown in the display.

To put complete freedom at your disposal when tuning your instrument, 

you have the option to change the preset of the reference tone “a”. Here is a quick 

intro to the subject.
The so-called “chamber tone a” has been continually revised upwards ever 

since it was first measured: tuning forks of Bach, Handel or Mozart were at 415, 

420 or 421 Hz (vibrations pro second). 
Nowadays, orchestra set the “a” with 444 Hz, and the Berlin Philcharmonic 

wishes to stay ahead still: their “chamber tone a” lies at a full 447 Hz.
The reference tone “a” of the BASS V-AMP/BASS V-AMP PRO is programmed 

at 440 Hz. Let’s say, you want to work with a big orchestra that works with 

the chamber tone “a” set to 444 Hz. To activate the function that changes the 

chamber tone, do the following: activate the tuner by pressing the TUNER key 

and immediately switch over into the EDIT mode by simultaneous pressing both 

arrow keys. “40” appers in the display, which responds to 440 Hz. By pressing the 

arrow keys, you can adjust the “a” reference tone up or down in 1 Hz increments 

for a maximum of 15 Hz. The last two digits of the frequency value are always 

shown in the display, since the first digit is always a 4. For example, when you 

start with the 440 Hz basic tone, and then press the right arrow key four times, 

the display shows 44, which corresponds to a frequency of 444 Hz. 
To quit the EDIT mode, press the TUNER key. Your changes are automatically 

stored. Ideal tones for the remaining strings are automatically set up using the 

newly adjusted frequency as a reference. 

Your BEHRINGER BASS V-AMP PRO needs two rack units to be installed in a 

19-inch rack. Please keep in mind that you need an extra 10 cm depth for 

accessing the cables running into the back.
Assure that appropriate ventilation is provided, and never position your 

BASS V-AMP PRO on top of an amp, for example, to avoid the danger of 

overheating the unit.  

carefully if your unit is set to the correct voltage! The fuse mount near the 

power cord connector has three triangular markings. Two of these three triangles 

are facing opposite one another. Your BASS V-AMP PRO is set up for the voltage 

indicated near these markings, and can be altered by turning the fuse mount by 

180 degrees. ATTENTION: This does not apply to export models built for 

Power is delivered via the cable that was delivered with the unit. All requiered 

safety precautions have been adhered to.
