CONTROLS AND CONNECTIONS
| 1. MONO INPUT SECTION |
| (1) MIC INPUT |
| The Mic input is an electronically balanced XLR type designed to |
(1) | accept signals from any balanced low impedance (Low Z) |
microphone. To accommodate condenser microphones, this input | |
| is also equipped with +48VDC phantom power globally switchable |
| to all XLR input jacks with the Phantom Power switch (22) on |
| the front panel. Dynamic or |
| require phantom powering. It will be necessary to adjust the |
| channel gain with the input Trim control (3) to achieve a nominal |
(2) | operating level. The XLR jack is configured for: Pin1 = ground, |
| Pin2 = positive (+), Pin3 = negative |
(4) |
[Note: The Mic inputs are more sensitive than the Line inputs.
(3)Also, do not connect mics with the power switched on, as indicated by the Phantom Power On LED (25) in the Master
Section of the front panel. Never use unbalanced mic cables with the Phantom Power switched on. Never short the +48VDC to ground, as that can cause serious damage to your mixer. Also, mute the Monitor/PA speakers when turning the phantom power on or off.]
(2) LINE INPUT
The Line input is designed to accept balanced or unbalanced line- level signals such as those from keyboards, drum machines, or samplers. There is enough gain available on the line input to accept even lower level signals, such as those from an unbalanced microphone or guitar output. Use the Trim control (3) to adjust for the desired level. If a balanced signal is to be connected to the line input, then a 1/4" TRS (stereo) phone plug should be wired for: Tip = positive (+), Ring = negative
