Connection And Setup - Adastra CM30 User Manual

Connection and setup

Connect the rear IEC inlet (13) to the mains 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 method will be used at the start.
Information about the differences between 100V and low impedance systems are detailed on the
following pages.
