As in the Control Room, the potential for feedback also exists in the Studio.

The talent microphones will usually provide a part of the signal that is going
out over the air.  If that signal is the one being monitored with the Studio
speakers, feedback will occur. To prevent this, the Studio mic faders are
usually set to MUTE the Studio output to prevent the occurrence of feedback.

The installer may have provided a source for studio headphones which will

not be affected by the studio mute.

ST Select Button

The ST SELECT BUTTON lets the operator choose the source to be

listened to in the Studio. The source can be any signal appearing at a console
input connector (except the producer talkback input), any of the four main
buses, either of the caller feed mix-minus buses, or either of the general
purpose mix-minus buses.

Press the ST SELECT BUTTON. The button lights, the CHANNEL

DISPLAY shows ST MON, and the SOURCE DISPLAY shows the signal
currently feeding the Studio output.  The ENTER BUTTON begins to flash.
Turn the SELECT KNOB until the desired source shows in the SOURCE
DISPLAY, then press the ENTER BUTTON (the ENTER BUTTON stops
flashing). This selects the displayed source as the source for the Studio
speakers. The source name also shows in the ST DISPLAY, and the ST
SELECT BUTTON light goes off. If an input is set up to mute the Studio, then
the Studio speakers will mute if that input is selected as the Studio monitor
source.

Whenever the Studio mute is activated, PGM may automatically be

selected as the Studio source. The installer, however, may have disabled this
feature.

If you don’t hit the ENTER BUTTON or move the SELECT KNOB for

ten seconds the select process will terminate, leaving the selection for the
phone section unchanged.

ST Display

The four character ST DISPLAY shows the source that is selected for

monitoring in the Studio.

ST Level Control

The ST LEVEL CONTROL determines the overall loudness of the signal

being monitored as it appears in the Studio speakers.

NOTE: If the Studio is muted and you turn the level control all the way up,
then remove the condition that has the Studio muted, the sound in the
Studio speakers will suddenly be VERY LOUD!
