Line Inputs 3,4,5
This section describes the installer configuration of the stereo line inputs 3, 4
and 5. For each input you can set the input sensitivity and configure the routing
to the outputs. You can choose whether the channel is stereo, mono or
combines two inputs into mono.
To configure the unit switch off power, remove the top cover and adjust the links
as shown. Avoid the power supply components shown greyed out on the
diagram.
Input Connectors
Each input has two RCA phono sockets, one for left
input, the other for right. Use either socket when
connecting to a mono source. These connectors are
standard on most CD, disc and tape players used for
background music. Use good quality screened audio
cable and reliable connector plugs.
Input Level Match
Set the two links for either low –10dBV or high +4dBu
equipment as shown. Check that the input meter LED
flashes between green and yellow on loud music.
Reposition the links if the meter reads too low or if the
red peak indicator flashes.
Routing
Each input can be routed to any combination of outputs
via the VCA or DIRECT signal paths. The left and right
inputs each have their own routing links. This lets you
route each to any combination of outputs so that you
can create mono and stereo feeds as required. Make
sure that all the routing links are fitted correctly. Set
unrouted links to the OFF position.
Routing Examples
These examples show how the routing links can be
assigned to provide combinations of mono and stereo
zones. It is usual for background music sources to be
routed via the VCA path so that they are affected by level
control and ducking. One exception is the jukebox
which would normally by routed direct so that it can
duck or mute other music sources.
