6.3. Source Connections and Input Setup
6.3.1. Input Selector Switch
The EA-AMP-12D-45A has several options for attaching sources. Global inputs A and B can be used to route
audio to any of the output zones, or a zone may be fed individually by its Local input. Settings and connections
vary based on the output settings used.
Each output zone (1-6) has its own switch to control the input used for the zone. Set the switch to GLOBAL A,
GLOBAL B, or LINE IN, depending on the source input desired for each output zone. See the following sections
for more information about the correct settings to use for specific applications.
6.3.4. Normal Mono Input (4/8Ω Output)
If a source only provides a mono output and it must be played through a normal stereo output, the source signal
cable must be split using an RCA 2 way splitter. Connect an RCA cable from the source output and use the splitter
to connect it to the desired left and right inputs. This will allow the source to play through both the left and right
channels equally. This applies to both LINE IN and GLOBAL inputs.
6.3.5. Bridged Mono Input (8Ω Output Only)
To connect a mono source for use with a bridged output zone, connect an RCA cable from the source output to the
left channel of the desired input.
Note: It is recommended to use the LINE IN of the bridged zone instead of a GLOBAL input unless only bridged
mono output zones are set to play that GLOBAL input. Normal output zones will only play mono audio through
the left channel speakers if the input is selected.
6.3.2. Normal Stereo Input (4/8Ω Output)
For normal applications, one output zone can power one left and one right channel. To connect a stereo source for
use in this application, connect an RCA cable from the source output left and right channel to the desired input left
and right channel of the amplifier.
6.3.3. Bridged Stereo Input (4/8Ω Output)
For applications where two-channel stereo requires higher output than a standard zone can provide, two output
zones can be bridged, with one used for left and one used for right audio. To attach a stereo source for use in
this application, connect an RCA cable from the source output left channel to the left channel LINE IN of the
zone connecting to the left speaker wiring. Connect the RCA cable from the source output right channel to the
left channel LINE IN of the zone connecting to the right speaker wiring. Set the input selector switches on each
bridged zone to LINE IN.
Note: When using bridged outputs for stereo audio, the global inputs may be used, but if they are, they can only
feed the bridged zone(s) to achieve stereo audio, and any other inputs must be attached to LINE IN of the zone
they feed.
To configure this application correctly, connect the source’s left channel output to Global A’s left channel input,
and the source’s right channel output to the left channel input for GLOBAL B. Then set the input selector switches
appropriately on the desired left and right output zones.
