The MV-C is a 2 channel MIDI controllable volume attenuator. With it's
variety modes it can be used for a lot of applications. Even mixing automation
via MIDI is possible. The MV-C sends and receives PHANTOM Power so that
it is possible to stack several MV-C's together. An external expression pedal
can control the volume or pan.
1 ) INPUT A and B
2 ) OUTPUT A and B
3 ) MODE selector Stereo - Dual - Pan.
4 ) MIDI RECEIVE CHANNEL selector (1-16)
5 ) CONTROL selector Prg. - Data - Byp.
6 ) INPUT for a Expression pedal
PHANTOM POWER:
Some other manufacturer are also using the MIDI jacks to distribute power from one unit
to another (Phantom power). This is easy to handle and you can probably save nerves,
time and money which means you need one power adaptor less. The required power may
now be supplied from your MIDI effect or keyboard.
The idea of the polarity and the connection is described in the ELECTRONIC MUSICIAN
issued #12/89. Some other manufacturer are also using this idea!
This is not a standard. Please check your equipment before using it!
MV-C BLOCK DIAGRAM
1 ) If INPUT B is not connected, channel B will be supplied with the signal of INPUT A.
2 ) If OUTPUT B is not connected the signal of
channel B is switched to OUTPUT A.
3 ) You can mix two different input sources to
OUTPUT A.
4 ) You can mix one input signal to OUTPUT A and
B.
5 ) The connected expression pedal controls either
volume or pan depen-
ding on the MODE
setting.

Thank you for purchasing this product!
7 ) Connect a 9V (9V up to 12V) to this jack.
Please check the correct polarity before.
8 ) POWER LED : Lit when power is supplied
and flashes on each incoming MIDI signal:
- Slow: Midi data accepted - Fast: Midi data ignored.
9 ) MIDI IN and MIDI THRU jacks.
MIDI-IN receives and MIDI-THRU sends PHANTOM
Power.
MIDI RECEIVE CHANNEL
1 ) Choose a MIDI receive channel (1-16) and adjust the
4 switches (4) regarding to the imprint on the unit or
the table:
CONTROL SWITCH:
1 ) P r g . :
The MV-C recognizes MIDI program changes
1-127 to adjust the volume or pan (balance).
2 ) D a t a : The MV-C recognizes MIDI control data to
adjust the volume (control # 7) or pan
(control # 10) or balance (control # 8).
3 ) B y p . : No MIDI data may change the volume. The MV-C is set to maximum volume (Attenuation = 1:1).
MODE SWITCH
1 ) S t e r e o : The volume of channel A and B will be adjusted with
MIDI program changes or MIDI volume data.
2 ) D u a l : The volume of channel A will be separetely adjusted
with MIDI program changes or MIDI volume data on
the set MIDI receive channel. The volume of channel
B will be adjusted with the MIDI program changes or
MIDI volume data on the 2.nd MIDI receive channel.
(Below the set channel number.) E.G. Ch.3 is below
Ch.4!
3 ) P a n . : The volume of channel A and B will be simultaneously
adjusted with MIDI program changes or MIDI volume
data on the set MIDI receive channel. The Pan /
Balance will be adjusted on the 2.nd MIDI receive channel. (Below the set channel number.) (CH.16
= Below Ch.1)
Switching to any mode will initialise the
volume and pan data to "64".
EXPRESSION PEDAL
1 ) Connect an expression pedal to jack (6).
2 ) You can control the volume or pan / balance
according to the diagram:
