8 ~ 11) Zone 1~4 output terminals. In addition to the normal 70V and 25V line outputs, there
are four groups of 70V or 25V (internally selected, see page 10) line terminals for 4 zones
which can be selected using the push buttons on the front panel.
12) AC input cable receptacle . AC inlet with three pin socket for use of either 115VAC or
230VAC selected by slide switch on rear panel (see page 4). The amplifier is factory set at
115VAC main voltage. (230VAC operation requires AC plug adaptor.)
13) AC 115V/230V selector switch (Beneath small metal cover, see drawing of rear panels
on page 4). Allows for selection of either 115VAC or 230VAC operation. For operating on
230VAC main voltage, remove the small metal cover with a screw driver and slide the
voltage select switch’s actuator from 115VAC(factory set, left side) to 230VAC(right side),
then re-mount the small metal cover with the 230VAC sticker showing on back of small
metal cover and tighten screws.
14) AC fuse holder. Line fuse for the amplifiers:
P–30FACC and P–30FACD - 2A for 115VAC
- 1A for 230VAC
P–60FACC and P–60FACD - 3A for 115VAC
- 1.6A for 230VAC
15) LINE output RCA jacks. This booster output supplies the input signal to an additional power
amplifier. This signal is after tone control and master volume control. In this fashion, very large
systems requiring more power can be accommodated.
16) AUX input RCA jacks. High impedance input available with parallel RCA jacks (for stereo
accessories combined for mono.)
17) MIC-4 (XLR connector) input. Accepts a balanced low impedance microphone signal
with an XLR connector.
18) MIC-3 (XLR connector) input. Accepts a balanced low impedance microphone signal
with an XLR connector.
19) MOH output level control. Controls volume of MOH output. (Music on hold)
20) MIC-1 VOX on/off switch. Allows for disabling of MIC-1 input VOX muting of the MIC-2~4
and AUX input during paging. This allows for multiple MIC paging/operation.
21) MIC-2 (XLR connector) input. Accepts a balanced low impedance microphone signal
with an XLR connector.
22) TEL/PAGING input level control. Controls audio level of telephone input.
23) MIC-1 (XLR connector) input. Accepts a balanced low impedance microphone signal
with an XLR connector.
Note: Screw terminal designations: G-GND, HOT-Signal positive, COM-Signal negative/common.
