Front Panel Features
Channels 1 to 4 have the extra benefit of built-in
signal in-line compressors [33]. These may be adjusted
to add just the right amount of compression to your
vocals and help prevent distortion and the effects of
tonsillitis.
The mic inputs may employ high or low gain based
upon the setting of the switch [32]. Please review the
gain switch settings on page 18 for more information.
PHANTOM POWER
Most modern professional condenser mics are
equipped for phantom power, which lets the mixer
send low-current DC voltage to the mic’s electronics
through the same wires that carry audio. (Semi-pro
condenser mics often have batteries to accomplish the
same thing.) “Phantom” owes its name to an ability to
be “unseen” by dynamic mics (Shure SM57/SM58, for
instance), which don’t need external power and aren’t
affected by it anyway.
The mixer's phantom power is globally controlled
by the phantom [46] switch on the front panel. (The
phantom power for all channels is turned on and off
together.)
Patchbay section
This is where you plug in things such as: microphones,
line-level instruments, guitars, and effects, a recorder,
PA system, powered monitors, powered subwoofer etc.
(The speaker-level outputs from the internal power
amplifiers are on the rear panel.) Check out the hookup
diagrams for some connection ideas. See Appendix B
(page 25) for further details and some rather lovely
drawings of the connectors you can use with your mixer.
7. MIC INPUTS
We use phantom-powered, balanced microphone
inputs just like the big studio mega-consoles, for
exactly the same reason: This kind of circuit is
excellent at rejecting hum and noise. You can plug in
almost any kind of mic that has a standard XLR-type
male mic connector.
Professional ribbon, dynamic, and condenser mics all
sound excellent through these inputs. The mic inputs
will handle any kind of mic level you can toss at them,
without overloading.
