This may, for some situations, make for a better overall communication
experience. If the operator requires more mobility, the Amron Model 2821-28
Remote Push-to-Talk Module can be used to extend the headset cable. It includes
a push-to-talk button on a clip-on belt module and comes standard with 25 feet
(7.6 meters) of cable (custom cable lengths are available).
The operator may also use the included Amron Model 2405-28 Push-to-Talk
Microphone. This microphone comes with two color-coded banana plugs. The
black plug goes into the OPERATOR HEADSET jack and the yellow plug goes in
the PUSH-TO-TALK JACK. To communicate with the chamber, the operator
presses the button on the side of the microphone. There is no chance of acoustic
feedback since the PANEL SPEAKER is cut-off when the operator uses the
microphone. When using the Push-to-Talk Microphone, the SPEAKER SWITCH
must be turned on in order to hear the occupants.
3.1.9 OPERATOR MICROPHONE - This is a dual banana jack (color-coded red) that
functions as the microphone input from the operator's headset. It is only used if the
operator is in Full Duplex (4-Wire) mode.
3.1.10 PUSH-TO-TALK JACK - This is a dual banana jack (color-coded yellow) that allows
for remote keying of the push-to-talk function of the 2810E-2001. The difference
between using the PUSH-TO-TALK JACK and PUSH-TO-TALK BUTTON is that the
button allows the operator to communicate using the PANEL SPEAKER as a
microphone. If both are used at the same time, the PANEL SPEAKER is active as a
microphone. This allows another operation crew member to talk to the occupants
using the PANEL SPEAKER even if the operator is away from the 2810E-2001
using the Remote Push-to-Talk Module in 2-Wire mode.
3.1.11 RECORDER OUTPUT - This is a single RCA Phono jack (color-coded black) that
provides a transformer isolated output of both operator and occupant
communications. It is designed to drive the standard line-level inputs of audio or
video recorders with input impedances as low as 600 Ohms. The RECORDER
OUTPUT will not record the signal from the AUXILIARY AUDIO INPUT.
3.1.12 AUXILIARY AUDIO INPUT - This is a set of two RCA Phone jacks (color-coded red
and white) that provides a means to connect an external audio signal for occupant
entertainment. Although this input will accept a stereo audio source, it will be
converted into a monaural signal before going to the chamber. This signal is not
heard in either the operator headset or the PANEL SPEAKER. The earphone output
of most MP3 players can be connected to this input using an adaptor cable like the
Amron Audio Adaptor Cable (Amron Part Number 180-1000-00). This feature will
only work if the chamber is wired in Full Duplex (4-Wire) mode.
There is no separate volume control provided for the AUXILIARY AUDIO INPUT.
The audio device provides the volume control. It is advised at the start of chamber
operations, and before the external audio device is turned on, that the operator
adjust and verify the CHAMBER VOLUME level is correct and comfortable for
occupants. Then starting with the lowest volume, adjust the volume on external
devices until a comfortable level is achieved. If the operator is connected in the Full
Duplex (4-Wire) mode, the volume level should not be so loud as to prevent
