The MS-702 also incorporates a dual-channel program interrupt system (IFB).
When activated, one or more stations can interrupt the program audio to either
another intercom station or a talent wearing Clear-Com’s wired or wireless talent
receivers. Clear-Com’s stand-alone IFB system can also be connected to this
station.
The MS-702 provides DC power to operate Clear-Com beltpacks and remote
stations. The power is distributed between the two channels and will support up
to 40 RS-601 beltpacks or 10 speaker stations or 12 headset stations.
Clear-Com’s fail-safe design automatically shuts down the power to a channel
when a short circuit or electronic overload is sensed on that channel. The other
channel will continue to operate normally. Once the fault condition is removed,
the MS-702’s fail-safe circuit will restore power, even under full load conditions.
LED indicators signal a short or overload on either channel.
The DC power output details are:
•
1.2A continuous output
•
2A peak output (not exceeding the 1.2A rating for more than 2 seconds
per 1 minute period)
The MS-702 will operate from any AC line voltage between 100 and 240 volts
AC at 50 or 60 Hz. The MS-702 installs in a standard 19-inch (48.26 cm)
equipment rack, using only one rack space. The steel chassis and extra-thick front
panel with integral rack ears maintains legendary Clear-Com ruggedness. Three
3-pin XLR connectors are provided for connection to each intercom channel.
The MS-702 is compatible with all Clear-Com party-line intercoms.
OPERATION
Normal operation of the MS-702 main station requires access only to the front
panel controls. The controls located elsewhere on the unit are intended to be
set-and-forget in nature. For intercom operation, set the listen-level controls for
each channel to the desired level and press the
talk
buttons when talking. If a
headset is used, set the
sidetone
control for each channel for the desired amount
of sidetone in the earphone. If using the panel mic and speaker, set the sidetone
controls for minimum feed-through to the speaker to prevent feedback.
FRONT PANEL
The controls, indicators, and connectors found on the MS-702 front panel are
shown in the following figure and are described in the text that follows. The
numbers in the left column refer to Figure 1-1.
