CONTROLS AND CONNECTIONS

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 ribbon-type microphones do not

 

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 (-), Sleeve = ground.

(5)

 

 

 

 

 

 

 

 

 

 

(Note: Only either the Mic or the Line input of a given channel can

 

 

 

 

 

 

 

 

 

 

be connected at one time. Never connect both simultaneously to

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

the same channel.)

 

 

 

 

 

 

 

 

 

 

 

(3) TRIM CONTROL

(6)

 

 

 

 

 

 

 

 

 

(7)

The trim control adjusts the input sensitivity (channel gain) of the

 

 

 

 

 

 

 

mic and line inputs on the mono input channels. This control can

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

be adjusted to accommodate input signals from a wide variety of

 

 

 

 

 

 

 

 

 

 

 

sources, from the high outputs from keyboards or drum machines

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

to the small signal outputs of microphones. This wide range

 

 

 

 

 

 

 

 

 

 

 

eliminates the need for Mic/Line switching. The best balance of

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(8)

 

 

 

 

 

 

 

 

 

 

S/N and dynamic range will be achieved if you adjust the TRIM

 

 

 

 

 

 

 

 

 

 

control on each channel separately so that the Peak Indicator

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

LED (7) for that channel lights occasionally.
