Intercom/Talkback

35.Post Switch(es): Determines which signal will be present on the selected Monitor Send. When the switch is in the “out” position the signal is sent post-EQ/pre-fader. With the switch depressed the signal is sent post-fader. There are two of these switches for each input channel. Each

switch is marked (1 - 6 and 7 - 8) to indicate the group of Monitor Outputs that it affects.

36.9/10 Pan: This control sets the balance of the channel’s signal between Monitor Sends 9 and 10.

37.L/R Pan: Sets the post-fader level of the signal in the L or R master output.

38.Channel Fader: The channel output level control (60 mm fader) which sets the level sent to the L/R master output. The range of this control is -90 dB to +10 dB with the reference setting at 0 dB (or unity gain).

39.Mute Switch: Mutes all monitor sends (1 through 10) and the L/R bus for the channel. When the Mute Switch is on the Mute/Clip LED (#40) will illuminate.

40.Mute/Clip LED: This red LED illuminates when the Mute Switch (#39) is activated. When Mute is not active it serves as a clip indicator to alarm when the signal is within 2 dB of clipping.

41.PFL Switch: Pressing this switch connects the channel’s signal (pre-fader), to the PFL mix and switches the Headphones and Wedge outputs from their default setting (AFL) to the PFL mix. By activating PFL on any channel the PFL signal is connected to the R meter to aid in setting the proper input gain. In addition, the Signal/PFL LED (#42) will illuminate until the channel’s PFL is turned off.

42.Signal/PFL LED: This yellow LED illuminates when the PFL Switch (#41) is activated. When PFL is not active it serves as a signal presence indicator, illuminating only when a signal above -15 dB is present on the channel.

The Intercom/Talkback section describes the communications portion of the SRM. Though the

two systems both accomplish a communication link, they are two totally separate functions and will be explained in that manner.

Intercom

The Intercom section is basically a ClearCom™ compatible intercom station built into the SRM. Two XLR connectors (female-in and male-out) are used to pass through the intercom line as well as a standard four-pin XLR for a headset. Momentary CALL and TALK buttons, along with a super bright red call lamp, provide message sending capabilities. The Mic Gain trim pot sets the operators

mic signal level while the Side Tone trim pot sets the amount of that mic signal sent back into the operators headphones. A HP Level control adjust the level of the signals coming through the intercom. A COM/PROG switch provides a switchable option of either spoken material (COM) or ongoing program material (PROG) from the console.

NOTE: Supply voltage is not provided internally from the console to the intercom line.
