BASS V-AMP/BASS V-AMP PRO
8. INSTALLATION
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.
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, 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.
8. INSTALLATION
8.1 Rack mounting (BASS V-AMP PRO)
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.
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.
8.3 Audio connections
The input of the BEHRINGER BASS V-AMP/BASS V-AMP PRO
is laid out as a mono 1/4" TS connector. Line Out, Aux In as well
as headphones output are laid out as stereo 1/4" TRS connectors.
Line outputs can be connected to both balanced and unbalanced
jacks. The DI OUT connectors of the BASS V-AMP PRO are
available as balanced XLR connectors. Digital outputs are
available as a cinch connector (S/PDIF) and XLR connector (AES/
EBU). The BNC connector is used to feed in an external
worldclock signal.
