Description
Mono broadcast
inputs (×2)
Line level mono audio connected here is broadcast
to all zones which have an analogue input source
selected.
There are two mono inputs with different priorities.
Audio connected to the LO input is transmitted by
Amplifiers at their current level.
Audio connected to the HI input is transmitted at a
preset level. Amplifiers which have a digital input
source selected, change to the fourth analogue
source so they can receive the high priority
broadcast audio.
Note
: High priority (HI) broadcast audio uses left
channel speakers. Low priority (LO)
broadcast audio uses right channel speakers.
USB (Type B) This is used by the installer to configure the Matrix
Switcher.
C-Bus (×2) Connects to the C-Bus network.

Digital zone

Each zone output is used to connect the Matrix
Switcher to one Amplifier in each zone. Additional
Amplifiers can be added to a zone by connecting
their Digital Audio In socket to the Digital Audio
Out of an existing Amplifier.
