Stereo Mode
In stereo mode, both channels operate independently with individ-
ual input gain controls. Signal at channel 1’s input produces out-
put at channel 1, while signal at channel 2’s input produces out-
put at channel 2’s output. Recommended minimum nominal load
impedance for stereo operation is 2 ohms per channel.
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 driving
two speakers with the same signal but with separate amplifica-
tion. The ‘Channel1’ and ‘Channle 2’ input gain controls individu-
ally 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. Therefore the voltage
is doubled, the peak power is quadrupled, and program power is
roughly three times as high as that of the individual 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 dam-
age to the unit due to excessive heat and current lim-
iting.
Use extreme caution when operating the amplifier in
Bridged Mono Mode. Never ground either side of the
speaker cable; the speaker load must “ float “ away from the
