7. systems The CM and CS series amplifiers can provide an output for a single 80 speaker by connecting the 8Q output 16 to the positive speaker connection and COM output 15 to the negative speaker connection It is important to ensure that the speaker load is no less than 8Q and that the power handling of the speaker is equal to or greater than the output power of the amplifier 60W Amplifier CM CS Series User Manual O adastra Operation When all connections to the amplifier are made turn all rotary controls down and switch on the power 11 and a power LED will illuminate Ensure a signal is being fed to the LINE IN connection and gradually increase the MASTER rotary control 5 part way for testing For CM mixer amplifiers increase the LINE IN rotary 3 until the output is heard through the speakers Turn up the MASTER to the maximum required volume level and reduce the LINE IN control if necessary Note If a line input is not connected to a CM series mixer amplifier the initial test can be made using the built in USB SD audio player See USB SD audio player section below for instructions If a microphone is connected make sure it is switched on and gradually increase the MIC control 2 whilst speaking into the microphone until the required volume level is reached Note The microphone should not be able to hear the speakers which can cause feedback squealing or howling noise Fog Siren Alert
8. using the supplied mains lead or an equivalent approved type Ensure that the voltage is correct as indicated on the voltage selector 12 and that the mains outlet is switched on Alternatively the amplifier can be powered by a 12V battery such as a car or boat battery by connecting the and of the battery to the 12Vdc INPUT 14 on the rear panel Note Ensure that DC cables are capable of handling the current 6A min recommended Connecting CS series slave amplifiers For CS series slave amplifiers connect the audio input to the LINE IN connectors 19 on the rear panel using good quality RCA leads The CS series amplifiers are mono so any stereo signals will be summed together and reproduced as a single output The signal maybe continued onto further amplifiers by connecting the LINE OUT connectors 18 to the LINE IN connectors of the next amplifier again using good quality RCA leads Connecting CM series mixer amplifiers For CM series mixer amplifiers connect any line level audio inputs to the LINE IN connectors 19 on the rear panel using good quality RCA leads Connect a microphone if required to the front panel jack or combo input 1 Further amplifiers can be connected from the rear LINE OUT sockets The CM and CS series amplifiers can be used either as 100V line amplifiers or standard low impedance power amplifiers These 2 configurations cannot be used together so it is important to decide which
