Operating The C valve
Setting Up the C valve (continued)
6. Plug the C valve power pack into a wall outlet and switch the unit on by pressing the power switch.
7. If you are using an instrument with your C valve, press the MIC/INST switch in to set the C valveOs input to
accept instrument levels. The LED will illuminate. If you are using a microphone skip this step and go on to the
next step.
8. The C valve features on board 48-volt phan-
tom power supply for connecting condenser
microphones.
IMPORTANT NOTE: With all phantom power sup-
plies, you can get an annoying POP when you engage
the phantom power supply, or when you unplug a
cable that has phantom power on it. Depending how
loud you are monitoring, this POP can cause damage
to your speakers, and even to your hearing. Be sure to
turn your speakers, and/or headphone levels, all the
way down when switching the phantom supply on and
off or plugging and unplugging cables.
If you are using a condenser microphone, turn
down your monitor speakers and/or headphones,
and then press the front panel 48 VOLT switch to
engage the phantom power.
9. Now, set a level by playing your instrument or
singing into your mic, and slowly raise the INPUT
GAIN control until you see the LED VU meter
reach a level of about O0dB�.
10. Be sure that your mixer or recorderOs input is
enabled and turned up. Now, slowly raise the
output VOLUME control until you reach a good
level, about O-3dB�, on the analog output VU
meter. Then, set a good level on your mixer or recorder.
At this point you should be sending a clean signal to your mixer or recorder and you can experiment with the
SATURATION, VOCAL EQ and ENHANCER features for fun. A detailed explanation of these functions will be
covered in the following sections of this manual.
