PANEL MICROPHONE GAIN
The preamplifier gain of the panel microphone can be adjusted over a range of 0
to 10 dB; the maximum is the panel microphone gain’s default setting. However,
if two stations are talking to each other at the same time with the panel
microphone gain set to maximum, feedback may occur even if the speaker mute
(see “Speaker Mute”) is set to maximum. In this case, it will be necessary to turn
the panel microphone gain down. Similarly, in some noisy environments it may
be necessary to turn the panel microphone gain down and have the operator talk
more closely into the microphone.
Refer to the
Eclipse Configuration System Instruction Manual
for instructions on
adjusting panel microphone gain.
SPEAKER MUTE
When a panel microphone and a speaker are used together, feedback is possible.
To reduce this possibility, the station software will mute (turn down) the speaker
level by some predetermined amount when both the microphone and speaker are
enabled. The speaker mute can be adjusted from 0 to 15 dB; its default setting is
6 dB.
Refer to the
Eclipse Configuration System Instruction Manual
for instructions on
muting the speaker.
PAGE VOLUME LEVEL
When Page Override is assigned to a label, the audio level at the destination
station(s) is predetermined. This function allows talking to someone even if his
station’s volume control is off. Two things will happen when a station activates
such a label:
• If the destination speaker was off, it will turn on.
• The station(s)’s speaker output will be at the predetermined level regardless of
the “Intercom” volume control setting, unless this control is set higher than
the predetermined level.
The page volume level can be adjusted within a range of 0 to 10, equivalent to
the front-panel control settings of 0 equals off and 10 equals full pot. The page
volume level’s default setting is 5.
Refer to the
Eclipse Configuration System Instruction Manual
for instructions on
using Page Override.
STATION-TO-MATRIX CARD BAUD RATE
The RS-422 serial data communication between a station and other devices can
operate at standard (19.2 k baud, the default) and long-line (9600 baud) baud
rates. Use long-line only if encountering problems with the standard baud rate.
The baud rate is set from the configuration program and the station
automatically adapts.
