The front panel trim pots provide level adjustments of the
Send
,
Aux Send
,
Aux Out
and
Caller Out
audio connections. Separate audio level controls
let you optimize the audio level(s) of STAC to match the audio levels re-
quired by the interfaced audio equipment.
In order to optimize the audio levels, have someone call the hybrid from
another location. Answer the line on a control surface and make adjust-
ments to the
Send In
,
Hold Audio
, and
Caller Output
controls. Be aware
that some suppression and/or echo may be heard while calibrating the audio
levels. Disregard this and continue until the end of the procedure. When the
hybrid is properly calibrated there will be no echo or suppression.
This pot adjusts the audio sent to callers when they are
On Air
. Adjust this
pot along with your console audio control until callers verify that the audio
level they are receiving is at a comfortable listening level. With comfortable
listening levels, the
Send LED
should illuminate solid green with an occa-
sional flash of amber on audio peaks. If the
Send LED
illuminates red, the
audio levels are clipping and should be decreased via the send level adjust-
ments.
This pot adjusts the level of the audio sent to callers when they are placed
On Hold
. This is usually a complete, undelayed program feed. Adjust this
pot along with your console audio control until callers verify that the audio
level they are receiving is at a comfortable listening level.
This pot adjusts the level of send and caller audio at the
Aux Out
connector.
Adjust this pot along with your console audio control to set the proper level
for your recording device or other external devices.
