DESCRIPTION OF CONTROLS

Input Channel Controls

+48 V Switch

When pressed, the +48 V switch applies phantom power to the XLR microphone jack for that channel. 48 volts DC appears equally on pins 2 and 3 to be used by condenser-type microphones requiring external power. Since this potential is equal, it is “invisible” to standard balanced dynamic microphones, hence the name, “phantom power.” Check the manual for the mics you plan on using to make sure that this phantom method is correct before you apply power.

JThe +48 V switch must be turned off if any electronically balanced line input (such as the balanced output of a tape recorder or CD player) is connected to the MIC IN jack; it could damage the output circuitry of such units.

Note: Make sure the Mic/Line Gain knob is set to its minimum before switching the +48V switch in or out.

Mic/Line Switch

This switches between MIC (up) and LINE (down) as the input source for the channel. The input routing after this switch to the short Monitor FADER or large Channel FADER is determined by the CHAN/MON REVERSE switch (see below).

PHASE (Ø) Switch

When turned on (down), the Ø (Phase) switch reverses the phase of the input. It affects both the Mic and Line inputs.

Mic/Line Gain

The MIC/LINE GAIN knob adjusts the sensitivity of both Mic and Line inputs. Proper setting of this control is essential for low-noise, distortion-free operation. In most cases, microphones require 30 to 60 dB of preamplification, while line sources need much less or none at all. If the Channel PEAK LED lights when the CHAN/MON REVERSE switch is up, or the Monitor PEAK LED lights when it is down, lower the MIC/LINE GAIN control.

Chan/Mon Reverse

Press the CHAN/MON REVERSE switch to select TAPE IN as the source of the Channel, and at the same time send Mic or Line (whichever is chosen by the MIC/LINE switch) to the Monitor FADER. Example: If all the console’s MIC/LINE and CHAN/MON REVERSE switches are down, all the main Channel FADERS will be getting signal from their respective Tape Returns, and all the short Monitor FADERS will be getting signal from the Line input jacks. This would be a typical mixdown patch. By releasing the CHAN/MON REVERSE switch, the large Channel
