FRONT PANEL CONTROLS IN DETAIL
Power switch
The power ( ) switch turns the AC power off ( ) or on ( ). When
the power switch is in the “off” mode, it completely interrupts voltage
from reaching the CR-1’s circuitry. The LED next to the power switch is
unlit when the power is off. When the CR-1’s power switch is in the “on”
( ) position, the CR-1’s circuitry is activated and the LED next to the
power switch will light up GREEN. There is no auto turn-on mode.
Because the CR-1 is an audiophile-grade, analog device, its circuitry
can benefit from reaching equilibrium after turn-on, much like other
high-end audio equipment. After the unit has been off, a brief period
of warm up (several minutes) is desirable for best sonic performance.
Unless you will not be using the CR-1 for an extended period of time,
we recommend that you leave the power switch on. The CR-1 draws
a small amount of power when on: approximately 26 watts.
Crossover Function (Bypass) Button
This feature allows you to share one or more subwoofers between separate
home theater and dedicated 2-channel stereo systems. This functionality can also
allow you to share main left and right loudspeakers between the two setups.
With your 2-channel preamplifier connected to the CR-1’s “Main Stereo
Inputs”, and your home theater preamp/processor or receiver’s Subwoofer
Output connected to the CR-1’s “Managed Bass Inputs”, the CR-1 will act as a
switch between 2-channel and multi-channel listening modes, via the “Crossover
Function” switch.
When the Crossover Function is set to “On” (Button pressed in, not lighted),
the “Managed Bass Inputs” are completely disconnected and the CR-1 receives
its input signals only from its “Main Stereo Inputs” and outputs low-pass-filtered
signals via its “Outputs to Subwoofer(s)” and high-pass-filtered signals via its
“Outputs to Satellites”. This is the correct mode for 2-channel listening, and
indicates that the CR-1’s active crossover filters are in-line and functioning.
When the “Crossover Function” switch is set to “Bypass” (button out, lighted
red), the CR-1’s “Managed Bass Inputs” are connected directly to the “Outputs
to Subwoofer(s)”. In this “Bypass” mode, the CR-1’s “Outputs to Satellite
Amplifier” will pass signals present at the CR-1’s “Main Stereo Inputs”, with no
processing. Each left or right RCA input passes signal only to the corresponding
left or right RCA output and each XLR/TRS balanced input only sends signal to
its corresponding balanced output. All of the CR-1’s crossover functions and level
controls are completely bypassed in this mode, meaning that whatever signals
are present at the inputs will be passed to the corresponding outputs. Most of the
CR-1’s front panel controls are inoperative in this mode. Only the “Subwoofer
Output Mode” switch and the “Output Muting” buttons will remain functional.
The primary purpose of the “Bypass” mode is to enable your multi-channel
receiver or preamp/processor to handle all bass management for your multi-
channel system. See Connection Scenario #2 for details on this method (page 22).
IMPORTANT: WHEN THE CR-1 IS “OFF”, SIGNAL WILL BE PASSED DIRECTLY
FROM THE “MAIN STEREO INPUTS” TO THE “OUTPUTS TO SATELLITE
AMPLIFIER”, WITHOUT FILTERING. THIS ALLOWS YOU TO LISTEN TO YOUR
2-CHANNEL SYSTEM IN FULL-RANGE MODE, WITH NO SUBWOOFER(S), BY
SWITCHING THE CR-1 TO “OFF”
