Example 3 (models CV4250 and up):
To feed Channels 1 and 3 with the left signal from a stereo source, and Channels 2 and 4 with the right signal (thus forming a
pair of stereo amplifiers), connect the left signal to Input 1, the right signal to Input 2, and set switches 3 and 4 DOWN, leaving
switch 2 UP.

Connecting Remote Control Plates
CV Digital amplifiers support remote volume control by Cloud RL-1 Series remote control plates.
Each channel has a 3-pin, 5 mm-pitch screw-terminal connector (REMOTE LEVEL) on the rear panel. Connect an RL-1 using
two-core screened cable as shown:

REMOTE LEVEL CONTROL WIRING
RL-1/1A
USE TWO-CORE SCREENED CABLE
Maximum reliable cable run is 100 m. An RL-1 will control the level in the channel from zero (“off”) to the maximum determined
by the setting of the rear panel LEVEL preset control.
The LEVEL port responds to a control voltage in the range 0 to 10 V DC (where 0 V produces maximum level). A DC voltage
in this range may be applied here to allow an external control system to vary the volume in each channel. Please see the
Installation and User Guide for full details.
