Chapter 14 Talkback / Oscillator This chapter explains how to use talkback and oscillator. About the talkback and oscillator functions Talkback is a function that sends the signal of a mic connected to the TALKBACK jack to the desired bus. This is used mainly to convey instructions from the mixing engineer to the performers or staff. If necessary, a mic connected to INPUT jacks 1-32 {1-48} can also be used for talkback. The M7CL also contains an oscillator that can output a sine wave or pink noise to the desired bus, and this can be used to check external equipment or to test the acoustical response of the room.

Talkback / Oscillator

This chapter explains how to use talkback and oscillator.

Talkback is a function that sends the signal of a mic connected to the TALKBACK jack to the

desired bus. This is used mainly to convey instructions from the mixing engineer to the perform-

ers or staff. If necessary, a mic connected to INPUT jacks 1–32 {1–48} can also be used for talk-

back.

The M7CL also contains an oscillator that can output a sine wave or pink noise to the desired

bus, and this can be used to check external equipment or to test the acoustical response of the

room.

The diagram below shows the signal ﬂow of the talkback/oscillator signals.

Here’s how the signal sent to the TALKBACK jack or an INPUT jack 1–32 {1–48} can be sent to

the desired bus.

In the function access area, press the MON-

ITOR button to access the MONITOR

screen.

In the MONITOR screen, the TALKBACK ﬁeld lets

you check the current talkback settings, and turn talk-

back on/off.

If you want to view or edit the talkback settings in

greater detail, use the TALKBACK popup window

described in step 2 and following.

Popup button

Opens the TALKBACK popup window.

TALKBACK IN ﬁeld

This indicates the input level of the mic connected to

the TALKBACK jack, and the phantom power on/off

status.

INPUT TO TALKBACK ﬁeld

Of the INPUT jacks 1–32 {1–48}, this indicates the

input sensitivity, input level, and phantom power on/

off status of the jack that is being used for talkback.

You can select an INPUT jack for talkback by pressing

the button located at the left side. If you press the

GAIN knob to be active. you can adjust the input sen-

sitivity using the corresponding multifunction

encorder.

ASSIGN ﬁeld

Indicates the bus to which the talkback signal is sent.

You can press this ﬁeld to open the TALKBACK

popup window.

TALKBACK ON button

Switches talkback on/off.
