CONNECTIONS
Stereo Mode
In stereo mode, both channels operate independently with in-
dividual input gain controls. Signal at channel 1’s input produces
output at channel 1, while signal at channel 2’s input produces
output at channel 2’s output. Recommended minimum nomi-
nal load impedance for stereo operation is 2 ohms per chan-
nel.
Parallel Mode
When set to Parallel mode, a signal applied to channel 1’s input
will be amplified and appear at outputs for both channel 1 & 2.
The parallel mode is well suited for applications in which driv-
ing two speakers with the same signal but with separate am-
plification. The ‘Channel1’ and ‘Channel 2’ input gain controls
individually control the out put level on channels 1 and 2.
Bridged Mono Mode
Bridged mono mode straps both amplifier channels together
to make a very powerful, single-channel monaural amplifier.
One channel ”pushes” and the other channel “pulls” equally,
doubling the power over that of either channel alone. There-
fore the voltage is doubled, the peak power is quadrupled, and
program power is roughly three times as high as that of the in-
dividual channel. Signal is applied to the channel 1 input only
and channel 1 input gain control is used to adjust signal level.
The input gain control belonging to channel 2 are not used.
Note : Bridged mono mode is to be used only when
the CV-Series is connected to a 4 or 8 ohms speaker
load. Use of Bridged mode with speaker loads of less
than 4 ohms can result in severe damage to the unit
due to excessive heat and current limiting. Use extreme cau-
tion when operating the amplifier in Bridged Mono Mode.
Never ground either side of the speaker cable; the speaker load
must “ float “ away from the amplifier chassis.
