Quick Setup

Some info about reading the detail section
found later in the manual (indexing this sec­tion would be helpful!)

Quick Setup Procedure

1. Attach the two wire whip
antennas to the BNC
connectors on the back panel
of the MS-700 master station.

2. Install the power cord and plug
it into the AC source. Turn on
the MS-700 with the front
panel power switch.

3. Insert fresh batteries into the
BP-700 bodypacks and turn
them "on" via the power switch
on the main volume control.
The power indicator near this
control should illuminate briefly.

4. Plug a compatible headset into
each BP-700.

5. Make certain that the
operating frequency ranges of
the MS-700 and BP-700 match.
If there is any question, look at
the frequency labels on the
bottom of the MS-700 and
inside the battery compartment
of the BP-700’s.

6. Verify that the frequency
ranges and specific frequencies
programmed into the MS-700
and BP-700’s are those
authorized for the location. If
you are not certain that the
currently-programmed
frequencies are correct, verify
each of them using the
procedure on page 7.

7. Move the BP-700 beltpacks at
least 6 feet (2 M) away from
the MS-700 and separate them
from each other by at least 10
inches (40 cm). Momentarily
depress the “A” pushbutton.

8. Observe the "RF" LED's on the
receiver section of the front
panel of the MS-700. The LED
corresponding to each active
BP-700 should be illuminated.
If not, recheck that the BP-700
is turned on and that the
frequencies are correct.

9. In turn, momentarily depress
the "B" and "C" pushbuttons
on each BP-700. The
corresponding receiver "mode"
LED's on the MS-700 should
illuminate red for pushbutton
"B", green for "C" and orange
for “D”.

10. Depress the "on" pushbutton
on the front panel of the
MS-700 for each active receiver
channel. The adjacent LED
should illuminate to indicate
that the channel is selected.

11. Speak into the headset
microphone for each BP-700
while alternately pressing and
releasing pushbutton "A" on
the unit. You should be able to
hear your voice in the headset
earpiece in one position or the
other. If not, the headset
microphone type may be set
incorrectly. See page 8 for
programming a BP-700 for
dynamic or electret
microphones.

Note: Whether audio is present

when the pushbutton is
pressed or when it is released
depends upon the programmed
operating mode of the BP-700.
See page 8 for details.

Q700 3

Quick Setup (continued)

12. While speaking into each of the
BP-700 headset mics, select the
corresponding monitor "

MON"

switch on the MS-700 front
panel. Observe the bar-graph
LED's on the left side of the
MS-700 front panel. The "-2"
LED should illuminate often on
voice peaks, but the "+3" LED
should illuminate only rarely.

13. If necessary, adjust the
microphone gain for the
BP-700 via the screwdriver
adjustment access hole on the
side of the unit closest to the
"D" pushbutton. This is the top
adjustment to the right of the
XLR connector and to the left
of the "D" pushbutton.

14. If applicable, connect the wired
intercom system to the rear
panel of the MS-700. Two
intercom channels can be
accommodated at the same
time. For standard Clear-Com
intercom lines, connect line one
to the IC1/IC2 XLR connector,
and line two to the IC2
connector. For "TW" and RTS
systems, both channels are on
the same connector, which
should be plugged into
"IC1/IC2".

15. Select "Clear-Com" on the rear
panel (Clear-Com – TW/RTS
pushbutton "in") for standard
Clear-Com lines, or "TW/RTS"
for Clear-Com two-wire or RTS
intercom lines (pushbutton
"out").

16. On the MS-700 front panel,
select one or both intercom
channels via the "on"
pushbuttons in the intercom
area on the panel. The
incoming signal can be
monitored by selecting the
appropriate monitor "

MON"

pushbutton and observing the
bar-graph LED's as described
above.

17. Adjust the intercom input and
output levels for the intercom
lines as necessary with the
front panel "in" and "out"
trimmers. If the "null" control
requires adjustment, see
page 14 “Operational Features.”

18. If applicable, connect balanced
line-level program audio or IFB
audio to the "PROG" XLR
connector on the MS-700 rear
panel. Monitor and adjust level
with the corresponding
controls on the front panel of
the unit.

MS-700 Controls and Indicators

Summary: This section gives a brief overview
of the controls and indicators of the MS-700
as found on the front and rear control panels.

Front Panel Controls
and Connectors

Monitor Volume Control

– Adjusts the
volume of the headset monitor output.
Used for aural monitoring of the output
for: internal receivers, intercom input,
program audio input, or transmitter audio
signal as selected by one of the 10 monitor
("

MON

") pushbuttons. Any combination of

these ten "

MON

" button functions can be
simultaneously monitored. If additional
MS-700’s are connected via the rear panel
‘monitor cascade’ (“

MON CAS IN

” and “

MON CAS

OUT

”), any combination of the ten monitor

("

MON

") button functions on any or all of

the MS-700’s can be monitored.

Monitor Output

– Stereo 1/4" (6.35 mm)
headset jack. Use only with stereo-wired
headsets (25 ohm minimum impedance per
side); connection of mono-wired headsets
will short one side of the audio and cause
distortion.

Monitor Bar-graph

– Five segment LED
bar-graph display, dB scaled, designated +3
dB (overload), -2 dB (normal peak), -7 dB
(high normal), -12 dB (normal), -24 dB
(active, low).

Receivers Controls
and Indicators

(identical for all six)

RF LED

– Indicates that the associated
receiver channel is receiving a valid RF signal,
including the tone squelch/data subcarrier.

MODE LED

–

• When off (when RF LED is on)
indicates that the associated BP­700 beltpack is sending the "mode
A" command (see below).

• When red, indicates that the
associated BP-700 beltpack is
sending the "mode B" command.

• When green, indicates that the
associated BP-700 beltpack is
sending the "mode C" command.

• When orange, indicates that the
associated BP-700 beltpack is
sending the "mode D" command.

BATT LED

– When illuminated, indicates
that the battery in the associated beltpack
is low. When this indicator first illuminates,
approximately 30 minutes of useful battery
life remains.

ON

- When selected (as indicated by the
associated LED), enables the receiver audio
and routes it to the other audio circuitry in
the MS-700.

MON

– When selected (as indicated by the
associated LED), routes a sample of the
receiver audio to the monitor amplifier and
bar-graph. The audio may be monitored
whether on not it is selected (ON).

LVL Control

– Trims the level from the
receiver channel to accommodate soft or
loud speakers. Limited adjustment range.

SQ Control

– Adjusts the signal level
squelch circuitry in the associated receiver.
Clockwise rotation will set the receiver such
that a stronger signal is required to open
the squelch gate in the receiver. The
squelch adjust control does not affect the
tone coded squelch function.

IC Controls and Indicators

(identical for two intercom interfaces)

PWR

– Indicates that the associated
intercom line is powered. For Clear-Com
lines, the LED's are independent and show
status for each line individually. For the TW
mode, both LED's will illuminate if the two­wire line has power on channel 2.

ON LED

– Enables the associated intercom
channel in the same manner as for the
receiver channels.

MON LED

– Operates in the same manner

as the receiver monitor (“

MON

”) switches.

IN Control

– Trims the audio level coming

from the wired intercom system (when ON).

OUT Control

– Trims the audio level from

the MS-700 to the wired intercom system

NULL Control

– For Clear-Com and TW
intercom interfaces, adjusts the different line
impedances to control the sidetone level.

PROG MON

– Enables the monitor
function for the incoming program or IFB
audio.

PROG IN

– Adjusts the level of incoming

program/IFB audio.

PROG TX MON

– Monitors the audio
input to the master station transmitter
main audio channel.

Frequency Programming
Controls

(Behind front panel door,

see detail drawing)

Function Select Switch

–
Selects the transmitter or
receiver to be programmed,
as follows:

• Position "0" – Accepts external
programming input via the 2.5 mm
connector.

• Position "1" – Programs receiver #1
frequency.

• Positions "2" through 6" – Programs
receiver #2 through #6 respectively.

• Position "7" – Programs the master
station transmitter frequency.

• Position "8" – With beltpack
connected via 2.5mm connector,
programs the beltpack receiver
frequency.

• Position "9" – With beltpack
connected, programs the beltpack
transmit frequency.
