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.

The PA-60 contains two separate high current amplifiers for each channel, each of which can drive up to fifteen
8-ohm speakers. With two channels available, this means the PA-60 is capable of driving a total of sixty (60) 8ohm speakers. For best results, connect ½ of the speakers for each channel between the two amplifier outputs
of that channel, to balance out the power handling. If both zones are used for the same audio signal, connect ¼
of the speakers to each of the four amplifier outputs if possible.
The more speakers that are used, the less shared power each speaker will receive, the softer they will each play.
A single speaker with a short speaker wire run can receive the full 60 watts of power, where if 60 speakers are
used, there will be less then 1 watt of power available for each speaker. See DOD# 895 for additional information
on paging horn volume per number of speakers being used. If additional paging power is needed, add a second
Viking model PA-60 for 60 more watts of paging power.
Another consideration when budgeting speakers is paging power that is lost in the wire runs. A single speaker on
a short heavy gauge wire will have no loss, but many speakers on a long light gauge wire will have an unacceptable
amount of volume lost. Use the below chart as a guide line to keep the volume lost limited to less then 5db. Using
half the recommended distance or half as many speakers per run will keep the volume lost limited to less then
3db.
A. Typical 8 Ohm Speakers
6
Note 1: Mount the amplifier close to where
the speakers are installed to minimize the
speaker wire run lengths.
Note 2: Using half the recommended distance or half as many speakers per run will
keep the volume lost limited to 3db.
Note 3: Doubling up the wires will allow
double the length, or reduce the amount of
volume loss.
Note 4: Heavier gauge wire, fewer speakers per run, and shorter runs will all minimize volume loss.
Note 5: Use 70-Volt or 25-Volt speakers in
applications that require wire run lengths
greater then specified in the chart.

Paging systems often utilize 70 volt or 25 volt speakers as a way to distribute audio with a minimal amount of
power loss in the wire run. Typically, 70/25 volt speakers have an integral step down transformer that converts
the high 70/25 volt signal down to a lower voltage for the speaker. The benefits of running a high voltage paging
system are identical to the benefits of running high voltage power lines. That is, the higher the voltage is, the
lower the current becomes. This is good because, as with lower current, there is less loss of power in the long
wire runs due to resistance in the wire.
Since the PA-60 has two amplifiers that are running in differential mode for each channel, the output across them
together will have double the voltage swing. This Bridge Tied Load (BTL) strapping of the two amplifiers enables
the use of 70 volt and 25 volt speakers when wired across screw terminals 1 and 4 of channel 1, and across
screw terminals 9 and 12 of channel 2. If increased volume levels are needed, use a higher power tap on the
70/25 volt speaker.
When using 25 volt speakers on the PA-60, each speaker will actually receive twice as much power as the selected
tap. To get 1 watt of power into a speaker, use its 1/2 watt tap. The sum of all the speakers’ power taps should not
exceed 15 watts on each channel, or 30 watts total for both channels.
When using 70 volt speakers on the PA-60, each speaker actually gets only ¼ as much power as the selected
tap. To get 1 watt of power into a speaker, use its 4 watt tap. The sum of all the speakers’ power taps should not
exceed 120 watts on each channel, or 240 watts total for both channels.
Even though the PA-60 is able to drive either 70/25 volt or 8 ohm speakers, it is not recommended to mix 70/25
volt speakers and 8 ohm speakers on the same channel.
7
C. 70-Volt and 25-Volt Speakers
If the installation requires very loud paging, one or two 8 ohm speakers can be BTL strapped across each channel’s
differential amplifiers, (like 70/25 volt speakers as described above). Connect one or two 8 ohm speakers across
screw terminals 1 and 4 of channel 1, and connect one or two 8 ohm speakers across screw terminals 9 and 12
of channel 2. This will provide 6dB more speaker volume than normal. If more than four 8 ohm speakers are
needed, wiring them as described in section 1 (above), will provide best results.
