DESCRIPTION

The AP2300 and AP23OOSA are dual-
diannel power amplifiers tor prolesstonai
sound reinlcicernent.

The APZSOOSA teatures stepped attenuators
that are calibrated in l-dB steps lrom O to 20
dB attenuation. 2-dB steps Irorn 20 to 30 dB
attenuation and 3GB steps Icr attenuation
beyond 30 dB. The AP2300 uses con-
tinuously variable attenuators The two units
are identical in all other respects

Each channel delivers 100 watts oi
continuous average power into 8 ohms or
150 watts into 4 ohms over lull audio
Irequency range In die bridge mode. the
amplilier can deliver more than 300 walls at
less than 0.10% THD.

Each channel is independently protected
against . . .

- Over temperature

v Excesswe output voltage

I Excessive phase shift

- Radioirequency interierence

' Shorted loads

The load is protected from stamp/shutdown
transients. intrasonic Signals. low ac line
voltage. and do. When a problem is

detected. an output relay automatically
disconnects the load Item the channel and
illuminates the Protect LED located on the
tram panel

The APZSDO has electronically balanced
inputs and accessory sockets lor plug-in
translorrnars and electronic modules. The
level controls are rear mounted to avoid
accidental changes, The universal power
transformer permits 100. 120. 200-. 220.
and 240V 50/60 Hz ac operation. The
EteotroVolce AP2300 power amplitier is tha
chorce for serious prolessional instaliaiiois
which demand the highest quality at high
power levels lot extended periods cl time
