Description
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.
Digital optical
input
Use this to connect a digital optical audio source to
the Amplifier instead of the digital audio (zone)
source. The digital audio format must be 44.1 or 48
kHz stereo. Some digital audio formats (such as
surround sound) are not compatible with the
Amplifier. Either a digital audio (zone) or digital
optical audio source may be connected to the
Amplifier, but not both simultaneously.
Digital audio
output
This is used to connect an additional Amplifier to the
same zone as this Amplifier. A Cat-5 cable is used to
connect to the additional Amplifier’s Digital audio
(zone) input. Both Amplifiers will use the same zone
(they will both select the same audio source).
C-Bus (×2) Connects to the C-Bus network.
