9. Zone selector switches
Select the desired broadcast zone.
Pressing the ZONE 1 and 2 switches allows the
ZONE 1 and 2 output terminals (14) to output
signals, respectively.
10. Master volume control
Adjusts the overall signal level.
11. LED level meter
Indicates an output level.
12. AC inlet
Connects to the supplied power cord.
13. Ground terminal
A functional ground terminal.
14. Output terminal block
Connects to speakers. Outputs signals at the
ZONE 1 and 2 output terminals when the front-
mounted ZONE 1 and 2 switches (9) are
pressed, respectively. The DIRECT output
terminal continuously outputs signals irrespective
of these switch settings.
15. Recording output terminals [REC OUT]
0 dB, 600 Ω, unbalanced. Output all input signals
before the master volume control. Connect a
cassette deck, etc. when recording the broadcast
contents.
16. Line output terminal [LINE OUT]
0 dB, 600 Ω, unbalanced. Outputs all input
signals. Connects to a signal processor such as
a limiter or equalizer. (Refer to p. 8.)
17. Power amplifier input terminal [PWR AMP IN]
0 dB, 600 Ω, unbalanced. Accepts output signals
from the signal processor connected to the Line
output terminal (16). (Refer to p. 8.)
Inserting an RCA plug disconnects the internal
power amplifier section from the preamplifier
section.
18. AUX input terminal [AUX 5]
–20 dB, 10 kΩ, unbalanced. A combined XLR
(female)/phone jack connector. Accepts external
equipment output signals.
19. AUX input terminals [AUX 3, 4]
–20 dB, 10 kΩ, unbalanced. Monaural RCA pin
jacks. Accept external equipment output signals.
20. Microphone/AUX input terminals
[MIC 5/AUX 1, MIC 6/AUX 2]
–60 dB, 600 Ω, electronically balanced (MIC 5
and 6) or –20 dB, 600 Ω, electronically balanced
(AUX 1 and 2). Combined XLR (female)/phone
jack connectors. The input level can be switched
between MIC and AUX using the function switch
(23).
21. Microphone input terminals [MIC 1 – 4]
–60 dB, 600 Ω, electronically balanced.
Combined XLR (female)/phone jack connectors.
Note
Use an XLR connector when connecting a
phantom-powered microphone to this terminal.
Using a phone plug instead may cause a noise if
it is touched or rotated.
22. Remote control terminal block
(1) Remote power ON/OFF control input
[POWER REMOTE]
Allows remote control of the unit's power
ON/OFF.
No-voltage make contact input.
(2) Remote volume control [REMOTE VOLUME]
Connecting a 10 kΩ linear taper volume control
across these terminals will allow remote control
of Line output and speaker output levels.
23. Function switch
An 8-bit DIP switch. Selects the following
functions:
(1) Phantom power ON/OFF for each MIC 1–6
(2) Input sensitivity for MIC 5/AUX 1 and MIC 6/AUX 2
Refer to p. 8 "FUNCTION SWITCH SETTINGS"
for details.
