FEATURES

•
Two Zone with two speaker switched outputs
Two pre-amplifiers and amplifiers, each with two speaker switched outputs.
Speaker A & B outputs are Zone 1, Speaker C & D outputs are Zone 2.
•
Remote controlled via Infra-red and Wired IR
The front panel is equipped with an IR receiver, so the AX250i may receive IR directly
from a PRX remote control, or other learning remote. The wired IR is decoded directly
by the AX250i (IR is not re-emitted out of the front panel)
•
RS232 Control
Full control and monitoring is available via RS232 of any Axium multizone amplifier or
KRX keypad. Only one RS232 connection is necessary to an Axium amplifier stack.
•
Audio Inputs
Four stereo inputs (CD, Tape, Tuner, & Aux) and one mono Input. (Utility)
•
Amplifier Power and Protection
50 Watts RMS into 8 ohms, capable of driving into 4 ohms. The amplifiers are
protected against short term output shorts, and high ambient temperatures.
Care should be taken to ensure adequate ventilation – see "installation guide"
•
Amplifier ON Status - "Amp-On"
Each Speaker output has front panel On status indication, and 12VDC outputs on the
rear panel connector. The output's are protected against shorts and back EMF voltage
surges which may occur if powering a relay.
•
Summed Amp-On
A "Summed Amp-On" 12VDC output is provided on the rear panel connector. This is
typically used to switch the Audio source component's AC power.
If any amplifier Zone or Speaker output in an Axium amplifier stack is ON, then this
output will be 12VDC. The output is protected against shorts and back EMF voltage
surges which may occur if powering a relay.
•
Power failure Restoration
After an AC power outage the AX250i restores it's settings to the pre-interrupted
state. All internal settings are stored in non-volatile memory.
•
Direct wiring Keypads & IR receivers
An IR input is provided on the rear panel connector, this is separately buffered both to
the IR output jack, and to the Axium expansion Bus (Axium amplifier stack)
•
Pre-amplifier output
The Zone 1 line level post fader output is provided on the rear panel
Typical applications are: Active sub-woofers & for connecting to higher-powered
amplifier.
•
Source select output
The Zone 1 line level (pre-fader) source select output is provided on the rear panel.
Typical applications are slave amplifier driven passive volume controlled speaker
networks.
