Description
Speaker outputs
These are used to connect to 4 Ω to 8 Ω speakers
which are rated at 25 W RMS @ 4 Ω (or 6 W RMS @
4 Ω if no external power supply is connected to the
Amplifier).
Digital audio
(zone) input
The zone output of the Matrix Switcher is connected
to this input. Alternatively a Multi Room Audio
Distribution Unit can be connected to this input,
providing one stereo audio input. In this mode, the
Amplifier can select between two audio sources:
Digital audio input and local input.
Zone outputs
(1 × RCA pair)
These are line level outputs of the selected audio
source as received by the Amplifier. The outputs are
affected by the volume, bass and treble settings of
the Amplifier.
Local inputs
(1 × RCA pair)
Use this to Connect a local analogue audio source
which is available to this Amplifier only.
External power
input
This provides power to the Amplifier (when a Matrix
Switcher is not used). An external power supply also
increases the Amplifier’s audio output capacity to
25 W RMS into 4 ohm speakers.
Power supply rating: 24 V DC, 3.75 A or 21 V AC, 3.5 A.
Infrared input This Phoenix socket connects to an IR Target,
allowing an infrared remote to control equipment
located near the Matrix Switcher. Refer to the Multi
Room Audio System Installation Instructions for
pinouts.
