60 Watt Compact Two Zone Amplifier

to Drive up to 60 Paging Speakers

Features

The PA-60 can directly drive up to sixty (60) 8 ohm paging
speakers or one hundred (100) 70 volt or 25 volt paging
speakers. Both channels can be fed the same input so the
PA-60 can be used as a single large amplifier, or each
channel can be fed different inputs so the PA-60 can be
used as a two zone amplifier.

Since each input has its own gain adjustment, one zone
can be turned up louder for warehouse paging horn
speakers, and the other zone can be turned down for of­fice ceiling speakers. Two zones can also be helpful for
instillations in which one group of speakers is connected
to a source that provides background music using the
Viking PI-1A Paging Interface unit, and the other zone
provides only paging.

The Viking models CTG-1 or CTG-2 can be used to add
clock controlled tones with paging to both zones, or one
zone can have just paging and be free of the time sched­uled alert tones. The same can be done with the Viking
model MTG-10 in which one zone can have just paging,
and the other zone can have paging plus the 10 different
siren, warble, and chime tones that the MTG-10 can pro­vide.

One or two PA-60’s can be added to the Viking model ZPI-
4 four zone paging interface to provide either 60 watts or
120 watts of total paging power in four zones. The PA-60
can also be used to add additional paging power to other

Viking paging products such as the PA-2A, PA-15, and
PA-30.

The PA-60’s inputs are transformer coupled so they are
floating and isolated. Because of this they and can be con­nected to any line level audio signal, or by turning down
the input gain control to unity gain, can be connected di­rectly to the output of another amplifier. Because of this
the PA-60 can be connected directly to an existing paging
system speaker wire run to extend the run with up to 60
more speakers.

A. Warehouse and Office Paging

Note: For information on speakers to use, ambient noise levels, and speaker wiring, see DOD# 498 and 895.

Step 1 Connect paging audio to both Channel 1 and Channel 2 audio inputs.

Step 2

Connect paging horns for the warehouse to one channel, and ceiling speaker for the office to the
other channel.

Step 3

Use the two separate gain controls to independently adjust the paging volume level for both the
warehouse and the office speakers.

Note: For information on speak­ers to use, ambient noise levels,
and speaker wiring, see DOD#
498 and 895.

Step 1

Set input level control to the unity
gain position as shown.

Step 2

Connect existing 8 Ohm speaker
wire run into one or both channel
inputs.

Step 3

Connect additional speakers to
one or both channels.

Step 4 Adjust gain if needed.

C. Add Additional Paging Power to Viking Model PA-2A, PA-15, and PA-30 Paging Amps

Note: For information on speakers to use,
ambient noise levels, and speaker wiring,
see DOD# 498 and 895.

Step 1

Connect 600 Ohm audio output of
the Viking model PA-2A (shown,
PA-15, or PA-30 to the audio in­puts of the PA-60.

Step 2 Connect speakers to PA-60.

Step 3 Adjust gain controls as needed.
