V-TONE GMX110/GMX210/GMX212/GMX1200H
6. INSTALLATION
You determine the input volume of the effect module by
using MIDI controller #7. This lets you adjust the volume of your
V-TONE to your own requirements. Since this controller does
not control master volume, you should first adjust the maximum
volume you need by using the master volume control, and then
use MIDI controller #7 to lower the volume. This function is also
called volume controller.
The operating range of the Wah effect is adjusted using MIDI
controller #15.
Furthermore, if youre using LFO-controlled modulation effects,
you can deactivate LFO and implement modulation via MIDI
controller #15. To activate this MIDI controller, you should first
set up the LFO velocity either directly on your V-TONE or set the
respective MIDI controller to value 0.
Of course, you can use a MIDI sequencer or a computer-
based MIDI editor for MIDI remote control, particularly in the home
recording environment.
5. TUNER
s The integrated tuner is activated by pressing the CHANNEL
key for about 2 seconds (directly on the amp or on the
footswitch).
5.1 Tuning your guitar
The chromatic tuner automatically recognizes the frequencies
of guitar notes. For A string, this means a frequency of 110 Hz.
When you connect your guitar to the V-TONE and strum 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 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 red tuner
LEDs (HIGH/LOW) near the FX display. The faster the LED blinks,
the harsher the deviation of the played tone from the note shown
in the display. If the middle LED (green) lights up, the tone you
played is completely in tune with the tone indicated in the display.
When the tuner is active, the loudspeaker outputs are typically
muted. However, sometimes it is preferable not to mute the signal
in order to let you have acoustic control of what you are doing
while you are tuning your guitar. For this reason, the V-TONE
has an integrated tuner level function.
s You can adjust tuner volume from 0 to 99 by using the FX
control. At 0 the guitar signal is completely muted. After a
successfully implemented adjustment, the display auto-
matically goes back to tuner mode.
5.2 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, orchestras set the a with 444 Hz, and the Berlin
Philharmonic Orchestra wishes to stay ahead: their chamber
tone a lies at a full 447 Hz.
The reference tone a of the V-TONE is programmed at
440 Hz. Lets 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:
s Activate the tuner by keeping the CHANNEL key pressed
for a few seconds.
s By turning the PRESET control, 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.
After about 5 seconds, the display goes back to tuner mode.
Your changes are automatically stored. Ideal tones for the
remaining strings are automatically set up using the newly
adjusted frequency as a reference.
A quick hit on the CHANNEL key lets you leave tuner mode and
go back to amp mode.
6. INSTALLATION
6.1 Audio connections
With the exception of the headphone output and the AUX input
(stereo jacks), audio inputs and outputs of your BEHRINGER
V-TONE are provided in the form of mono jack connectors. Tape
inputs and outputs are provided as RCA connectors.
+ Please keep in mind that your V-TONE should be
installed and operated only by those who possess
sufficient technical knowledge about its installation
and operation. Everyone dealing with your V-TONE
should be sufficiently grounded both during the
installation as well as during actual usage. Failure
to do so may cause undesirable or faulty operation
due to electromagnetic discharges and similar.
