assign level, providing maximum level when in the center position and continuously decreasing in level when turned to the left or right. This makes true LEFT-CENTER-RIGHT (L- C-R) panning possible. (See also BUS ASSIGNMENT, PAN Switch)

PAN Switch

With the PAN switch up, groups can be individually selected and are unaffected by the PAN control. With PAN switch down, the PAN control varies the level of the group assign- ments with odd numbered groups on the left and even num- bered groups on the right.

Phantom Power

Phase

All console connections are in phase with each other, including insertion sends & returns. XLR pin 2 and jack tip are the posi- tive (+) phase connectors.

Polarity Reverse Switch

This post insert return, pre-EQ switch reverses the phase of the line and microphone input signals in the GTx input modules (on the stereo input module, this switch acts upon one channel only). This feature can be used to adjust phase cancellation between microphones when more than one microphone is pick- ing up the same acoustical signal. See also User Options.

Pre/Post (Aux) Fader Switches

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. When in the post-fader position, signal output level from the Aux sends will proportionally follow the main signal level. The result is maintenance of an effect in propor- tion 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.

(See INSERT/RETURN JACKS)

Right Meter

Located on the GTx meter bridge, this VU-type meter indicates the Right output level, post fader.

Scene Mute Assignment Switches

On input modules, the scene mute switches assign the input to one or more of the master scene mutes. On the group modules, the scene mute switches assign the Effects Return to one or more of the master scene mutes. These mutes are activated via the scene mute master switches found on the master section. Any combination of mutes is allowed.

Scene Mute Master Switches

Found on the GTx Master Section, these switches activate/deactivate the four scene mutes. Associated red LED's indicate status.

Scene Mute Safe Switch w/LED

This switch, found on input and group modules beneath the Scene Mute Assignment Switches, disables any selected scene mutes, and is generally used to prevent accidental channel mut- ing. A green LED indicates that the Safe switch has been engaged.

SOLO LEFT/SOLO RIGHT Meters

Located on the GTx meter bridge, these VU-type meters indi- cate PFL/AFL signal level. Inherently, they also reflect the headphone signal level. When PFL or AFL is engaged any- where on the console, the SOLO LEFT and SOLO RIGHT level meters go from being dimly lit to being the same bright-

ness as the other level meters.

Soloing (PFL/AFL)

Both methods of soloing allow for monitoring within the mas- ter section of the console

When soloing input channels, optional matrix inputs, groups and main outputs, monitoring is done pre-fader, or PFL. The PFL (Pre Fader Listen) switch enables the operator to listen to channel signals before the fader or main channel level control (PFL). This signal IS NOT affected by the Channel Mute Switch.

When soloing Matrix Masters or Aux sends, monitoring is done after-fader (AFL); the associated AFL (After Fader Listen) switches enable the operator to listen to Matrix Master and AUX signals after the rotary Matrix Master /Aux level controls. When soloing a single Matrix Master or Aux signal individually, monitoring is done in ‘mono’; when soloing more than one Matrix Master or Aux signal, solo monitoring will be heard as a stereo ‘split’, odd on left, even on right.

When either an AFL or PFL switch is pressed, the solo signal level can be seen on the Solo Left/Right meters, and can be heard both in the mixer’s headphone output and on the rear panel monitor output of the console.

When PFL or AFL is engaged anywhere on the console, the SOLO LEFT and SOLO RIGHT level meters go from being dimly lit to being the same brightness as the other level meters, and two red LED's on the console panel illuminate.
