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
