5.2 Communications
System 5-B’s communication system includes:
• Two talkback microphone inputs (one mic included).
Each input has 111 dB of gain, phantom power, and a compressor. The talk-
back mics can be mounted anywhere but normally Tbk1 is mounted near the
engineer and Tbk2 near the client. Talkback can be routed to Mon A–D, the
Aux busses and the Main sections (via the Slate function). Tbk2 shares the
same routing as Tbk1 when it is turned on. Talkback can be remotely triggered
to Mon A–D.
• Four listenback mic inputs.
Each input has phantom power and compressor. They can be routed to the
monitors and have individual level controls.
• Oscillator with Slate facilities.
The oscillator has four fixed frequencies at 100 Hz, 440 Hz, 1 kHz, 10 kHz, and
a user-selectable frequency. The oscillator can also generate pink or white
noise. The oscillator can be routed to the Group, Aux, or Main sections, or to
all busses simultaneously. The Slate function combines Tbk1 and Tbk2 with a
user-definable tone to identify takes.
NOTE: The Listenback mics are routed directly within the Monitor Interface (MC524)
so they do not appear in PatchNet.
Access the communications facilities by pressing the Comms Ctrl key in the Solo Ctrl
section to display the Comms:Talkback Panel (left of Figure 5-5). The bottom of the Pan-
el has Talk, Lsn, and OscSlt keys to display Talkback (shown), Listenback (page 63),
and Oscillator/Slate Panels (page 64), respectively. The Comms:Talkback Panel has an
Aux key at bottom-right to set the talkback settings for the Aux busses. When display-
ing the Comms:Talkback:Aux Panel (right of Figure 5-5), this key changes to Mons,
which switches back to the panel shown in the left of Figure 5-5.
