15 BASS V-AMP LX1B/BASS V-AMP PRO LX1B PRO User Manual
6.3.3 Special eects
VCF+FLANGER: The combination of lter and anger eect.
VOICE BOX: This vocal simulation fades between various vowels (a/e, a/i, a/oetc.)
by using a LFO (Low-Frequency Oscillator). You can control this eect via a MIDI
footcontroller.
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 ampliers have no
subharmonic function. The ULTRABASS processor, which has also found home in
various BEHRINGER bass amps, makes creating this eect 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 eect gives you a rad three-voice synthie bass and has many
parameters that are pre-congured 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,thereis
an “intelligent” envelope follower based on key and interval, whereas the
VCO 1 (Voltage Controlled Oscillator) is set up for specic intervals, and the
BASSV-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 oers 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,
EFFECTmax.= 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 eect that is normally achieved
with a terribly heavy casing and slowly or quickly rotating speakers. The physical
principle of the Doppler eect is used to modulate the signal.
7. Tuner
The integrated tuner is activated by pressing the TUNER key.
7.1 Tuning instruments
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.
7.2 Setting up the “a” reference tone
To put complete freedom at your disposal when tuning your instrument,
youhave 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 rst measured: tuning forks of Bach, Handel or Mozart were at 415,
420or421 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 rst 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.
8. Installation
8.1 Rack mounting (BASS V-AMP PRO)
Your BEHRINGERBASS 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
BASSV-AMP PRO on top of an amp, for example, to avoid the danger of
overheating the unit.
8.2 Voltage (BASS V-AMP PRO)
Before you connect your BASS V-AMP PRO to the mains, please check
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
120 V, for example!
◊ If you use the unit with a different voltage, you must change the fuses
accordingly. The correct value of the fuses needed can be found in the
chapter “Specifications.”
◊ Faulty fuses must be replaced with fuses of appropriate rating without
exception! The correct value of the fuses needed can be found in the
chapter “Specifications.”
Power is delivered via the cable that was delivered with the unit. All requiered
safety precautions have been adhered to.
◊ Please make sure that the unit is grounded at all times. For your own
protection, you should never tamper with the grounding of the cable or
the unit itself.
