Bridge-Mode Operation

Having four or eight channels available per amplifier suddenly puts bridge-mode operation into a completely new context. As an example, the C 68:4 gives you the option of two channels of 1700 W and one channel with 2400 W into 4 ohm loads.

Usually, bridging a power amplifier causes the amplifier gain to rise by 6 dB; hence, it often makes users believe that the amplifier delivers “more than twice the power”, when in fact it is just additional gain.

C Series amplifiers automatically compensate for this phenomenon by introducing a gain reduction of -6 dB, therefore maintaining the same gain settings for all channels. This greatly simplifies the task of specifying and aligning speakers.

Bridge mode is easily configured via DIP-switches on the rear panel. Any two adjacent channels can be bridged independently. Input channels A and C (or A, C, E and G with eight-channel models) would be used to provide signal for the bridged channels.
