Table 2: Rear Panel Features
Connection/Indicator Description or Function
Power switch Switches the unit on and off.
Infrared Outputs (IR OUT
2 – 3.5 mm)
These 3.5 mm sockets connect to IR Emitter leads. IR Emitters are then coupled
to IR receivers on A/V equipment to provide remote control from any zone.
Digital Audio Outputs
8 – RJ45
Each zone output is used to connect the Matrix Switcher to one amplifier in each
audio zone.
Ethernet LAN
1 – RJ45 (Deluxe Matrix
Switcher only)
This RJ45 socket enables connection to a local (computer) network for the
streaming functionality of the Deluxe Matrix Switcher.
Audio Input (Source
Inputs) 4 – RCA pairs
Most A/V devices connect to the Matrix Switcher through the four standard stereo
Analog inputs. These line level RCA sockets are numbered 1 through 4. Input 4 is
electrically tied to the front panel AUX connector. This input should be used as
either a line-level input (rear panel) or a headphone-level input (AUX input), not
both.
Broadcast Inputs
2 – RCA
Line level mono audio that is connected here is broadcast to all zones that have
an analog input source selected. Refer to the Annunciation section of this
manual.
Unit indicator and
C-Bus indicator
Unit and C-Bus indicators show network status and activity.
C-Bus Ports
2 – RJ45
There are two connections for the C-Bus network to allow for looping through to
additional pieces of equipment.
Digital Audio Input
1 – RJ45
Use this connection when using an optional MRA Distribution Unit to provide an
additional stereo audio input.
USB Port
1– Type B
This connection is used for programming the Matrix Switcher during
commissioning by the installer using a PC running MARPA configuration
software.
AM/FM antenna
1 – Type-F coaxial
One antenna connection serves both internal AM/FM tuners.
Optical input/output Used to connect a digital optical audio source for distribution to any of the eight
zones. 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 Matrix
Switcher. The optional output is provided so that the input can be sent on to
another piece of A/V equipment. You cannot use the optical input and the
DIGITAL AUDIO IN at the same time.
Power cord connector and
fuse holder
Connect the power cord here to power the Matrix Switcher. The Matrix Switcher
also provides power for connected amplifiers that do not have an external power
supply. The Matrix Switcher requires a 3.15A, 250V, 5x22mm glass fuse.
HI/LO adjustment
2 – trimpots
These adjust the level of the audio source connected to the mono broadcast
inputs. Use a small Phillips screwdriver to rotate the control if the audio source is
too quiet or loud. Refer to the Broadcast Audio Input and Adjustment Locations
figure for trimpot locations.
