Connection
/Indicator
Description
Speaker outputs The Desktop and Remote Amplifiers use spring-type connectors.
The Low Power Amplifier uses screw-terminal connections.
Headphones
1 – 3.5 mm
stereo
This connector is usually wired to a wall plate. The headphones
operate independently from the speakers. Use the mute button to
turn the speakers on and off.
External power
input
This connects power to the amplifier. An external power supply is
connected when a matrix switcher is not used, or to increase the
high power amplifiers' audio output capacity to 25 W RMS into
4-ohm speakers.
DIGITAL AUDIO
IN
1 – RJ45
The zone output of the Matrix Switcher is connected to this input.
Alternatively, a Distribution Unit can be connected to this input,
providing one stereo audio input. MRA amplifiers can select
between digital audio input and local input.
DIGITAL AUDIO
OUT
1 – RJ45
This is used to connect an additional amplifier for use in the same
audio zone. Both Amplifiers will use the same audio source). A
Cat.5e cable is used to connect to the digital audio input of the
second amplifier using a 5600TEE adapter.
LOCAL IN
1 – RCA pair, or
3.5 mm stereo
Use this to connect a local analogue audio source that is available
to this amplifier only.
ZONE OUT
1 – RCA pair
These are line level outputs of the selected audio source as
received by the amplifier. The volume, bass and treble settings of
the amplifier affect the outputs.
Digital optical
input
Use this to connect a digital optical audio source to the amplifier.
Either a digital audio (zone) or digital optical audio source may
be connected to the Amplifier, but not both simultaneously.
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.
IR TARGET This socket connects to an IR Target, allowing an infrared remote
to control equipment located near the matrix switcher (through
emitters connected to the matrix switcher).
C-Bus
2 – RJ45, or
screw terminal
Connects to the C-Bus network. The Low Power Remote Amplifier
uses a screw terminal connector.
Unit and C-Bus
indicators
Refer to Section 2.3.
