seen on the Left/Right/Monitor meters, and can be heard both in the mixer’s headphone output and on the rear panel monitor output of the console. When the PFL Switch is depressed, the channel PEAK LED indicator illuminates at a low intensity. When used as an indicator of switch position, the Peak LED indicating circuit remains fully operational by illuminating at a much higher intensity than its use as a status indicator.

Talkback Assignment Switches

These switches assign the talkback signal to the outputs and/or auxes.

Phantom Power

See 48V PHANTOM POWER

Polarity Reverse Switch

This switch is used on input channels to adjust between dissim- ilar microphone output polarity (see your microphone’s instruction manual). It is also used to adjust phase cancellation between microphones when more than one microphone is pick- ing up the same acoustical signal (This should be kept to a minimum with proper microphone placement).

Pre/Post Fader Switch

Switches the Aux signal sources between pre-fader and post- fader positions. The pre-fader position is usually used for mon- itor sends, so that any movement of fader level does not affect these outputs. This is desirable for monitors, since their levels normally need to be operated independently of the main (front- of-house) system. When in the post-fader position, signal out- put level from the Aux sends will proportionally follow the main signal level. The result is maintenance of an effect in pro- portion to the main signal level. When an input signal is faded to 0dB, the post-fader Aux Send signals are also decreased to 0dB. In some cases, it may be desirable to derive effect sends pre-fader for special effects, such as those generated by a vocal doubler or harmonizer. The choice of switch position should be determined by the actual situation; though as a general rule, choose the pre-fader position for monitor sends and post-fader position for effect sends.

Right Meter

This ten segment LED meter normally displays the signal level of the Right output. If any signal is in PFL or AFL mode, then this meter displays that signal instead.

Scene Mute Assignment Switch

Found on GT input and group modules, these switches assign the input or EFX Return signal to one or more of the scene mutes. These mutes are activated via the scene mute master switches found on the master section.

Scene Mute Master Switches

Found on the GT Master Section, these switches activate the four scene mutes.

Scene Mute Safe Switch w/LED

This switch, found beneath the Scene Mute Assignment Switches, disables any selected scene mutes. A green LED indicates that the Safe switch has been engaged.

Signal Present LED

This LED displays, in real time, the level activity of the chan- nel by varying the intensity. Any illumination of this LED indicates that a signal is present and is somewhere within the usable operating level. Optimum operation is when this LED is at a bright but varying intensity and following the channel’s

Talkback Level Control

This knob controls the final level of the talkback signal, and dims local monitor output, if Dim switch has not been pressed.

Talkback Microphone Input

Found on the master section (GT) and under the arm rest on the right side, these balanced XLR inputs allow for a micro- phone or other balanced mic-level source to be connected to the talkback system.

Talkback On Switch

This switch activates the entire talkback system including the internal oscillator.

XLR Balanced Outputs

This output is designed to drive both balanced and unbalanced input devices without adaptation. Signals are normally bal- anced on this output connector. The output is designed so that if either pin 2 or pin 3 were intentionally shorted (as in con- necting to an unbalanced input of your next stage of electron- ics) or accidentally shorted, the output level of the non-shorted connector pin increases by 6db. This is an amount equal to the normal loss of a balanced output when one pin of a balanced output is shorted. The result is no need for external gain make up.

XLR Microphone Input Connector

Balanced XLR Input is designed to receive professional Low Impedance microphone signals. The input Gain controls on the front panel adjusts for most input levels. In the event of exces- sive input levels, the front panel input pad switch should be depressed. Front panel selection of 48 Volt Phantom power enables most types of condenser microphones that require such power to be used. (Note: most input devices can tolerate 48 Volt phantom power to be placed on their output terminals (provided they are truly balanced) without causing damage to the device. See your device’s operating manual for correct operation. (If in doubt as to whether your non-condenser microphone may be damaged by using Phantom Power, please make sure that the front panel phantom power switch on that input channel is in the off [out] position.)

This input may also be used for low level line input signals, provided the source (instrument) is able to drive a 5k Ohm or higher load. (See your instruments or electronics owner’s man- ual for output impedance.) When line output devices such as tape players are plugged into the microphone input, special care should be observed that the phantom power is turned off on that channel, as damage may result. Because of this, it is recommended that the 1/4" line input connector be used when connecting a line level device. 48 Volt Phantom power is not present on these input connectors, and the impedance of the line input connector is high enough to accept any line level device.
