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
14)AC fuse holder. Line fuse for the amplifiers:
-1A for 230VAC
-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)
with an XLR connector.
18)
19)MOH output level control. Controls volume of MOH output. (Music on hold)
20)
21)
22)TEL/PAGING input level control. Controls audio level of telephone input.
