CONNECTIONS
Stereo Mode
In stereo mode, both channels operate independently with in-
dividual input gain controls. Signal at channel 1’s input pro-
duces output at channel 1, while signal at channel 2’s input
produces output at channel 2’s output. Recommended mini-
mum 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 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 CXA-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 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 amplifier chassis.
