The M15W amplifier output appears across pins 1 & 4 which can drive 8 to 4-ohm loads. Pins 2 & 3 are internally shorted
which allows series connection of two lower impedance loads, to still maintain a 4 to 8-ohm load across the amplifier out-
put, as shown.
(1) 25AE Paging Horn included.
Additional 25AE Paging Horns
and 30AE Ceiling Speakers
may be added.

The M15W is a power amplifier that amplifies the signal from a line level source (600 ohm input) or an already amplified
source (8 ohm input). The signal passes through a gain adjustment (paging volume), a tone control and a high-efficiency
class D amplifier. The amplifier is short circuit protected.
To keep background hum noise to a minimum, set the audio source to a loud setting and adjust the paging volume control
on the M15W for the desired speaker volume level.
