SCENARIO 2 CONNECTION DIAGRAM:
2-channel Subwoofer/Satellite System that is Bass-Managed by the CR-1 and also
shares active subwoofers with a separate multi-channel home theater system
This scenario shows how you can share your room’s subwoofer(s) between
a completely separate home theater (HT) and a stereo, 2-channel system. In
this scenario, your HT receiver (or amplifier) will power dedicated Left, Center,
Right, and surround speakers. A separate, dedicated stereo amplifier will power
separate, dedicated stereo Left and Right speakers (not shared with the HT setup.)
The subwoofer(s) will be shared between both systems, using the CR-1 as a switch
to select the operating mode.
Most HT receivers and preamp/processors provide a single (mono) subwoofer
output; however, a few high-end receivers and processors may offer dual subwoofer
outputs. For this reason, CR-1 has left and right “Managed Bass Inputs”.
The 2-channel amplifier and preamplifier connect to the CR-1 exactly as
shown in the diagram at left and as described in Scenario #1, on page 14.
Next, connect the HT receiver’s or HT preamp/processor’s subwoofer outputs
to the “Managed Bass Inputs” on the CR-1. You may use XLR (balanced) or
RCA (unbalanced) cables to make these connections. Then, set the “Input Type”
switch located next to the “Managed Bass Inputs” to the “Stereo” or “Mono”
position, depending on the output from your HT receiver or HT preamp/
processor (this switch will usually be set to “MONO”.)
If you connect only one subwoofer signal to the “Managed Bass Input”, be
sure to use the corresponding Left or Right “Output to Subwoofer” on the CR-1.
Using the opposite one will result in no subwoofer signal.
If you are using one subwoofer, set the CR-1’s front-panel “Subwoofer Output
Mode” switch to “L+R” (mono.) If you are using more than one subwoofer, you
may decide whether to choose “L+R” (mono) or “Stereo” subwoofer modes
depending on your room setup and personal preference.
IMPORTANT: WHEN THE CR-1 IS OPERATING IN “BYPASS” MODE, THE
“SUBWOOFER OUTPUT MODE” SWITCH ON THE FRONT PANEL WILL HAVE
NO EFFECT AND THE MANAGED BASS SUBWOOFER SIGNAL FROM YOUR
HT RECEIVER OR PREAMP/PROCESSOR WILL BE PASSED THROUGH THE
CR-1 WITH NO ALTERATION.
IMPORTANT
When the CR-1 is connected as shown in
this scenario, the operating modes and
behaviors are as follows:
Power: On and “Crossover Function”
switch: “On”
“Outputs to Subwoofers” are low-pass
filtered by the CR-1
“Outputs to Satellites” are high-pass
filtered by the CR-1
Power: On and Crossover Function
switch: “Bypass”
“Outputs to Subwoofers” pass signals
directly from the “Managed Bass Inputs”
“Outputs to Satellites” pass signals
directly from “Main Stereo Inputs”,
unfiltered (full-range).
Power: Off
“Outputs to Subwoofers” are off
“Outputs to Satellites” pass signals
directly from “Main Stereo Inputs”,
unfiltered (full-range).
