The power switch must always be on the “off” position before plugging the amp to a properly earthed mains soc- ket (220-240v ac). The input signal fed to the amplifier can be either balanced or un-balanced. The drawing below describes both ways to wire an xlr connector for the purpose. Balanced sign...
Installation and operation installation et mise en service the amplifier can operate on two diffe- rent configurations: dual or bridge (mono or stereo). The connections for the two modes are different. See figure - switch “off” the amp. - set the mode switch on the rear panel to “dual”. - connect th...
