Connection And Setup; Speaker Outputs - Adastra RS605 User Manual

Connection and setup

Connect the rear IEC inlet (7) 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 (6) and that the mains
outlet is switched on.
Alternatively, the RS605 can be powered by a 24V battery, such as a lorry or boat battery, by
connecting the "+" and "-" of the battery to the 24Vdc INPUT (8) on the rear panel.
Note: Ensure that DC cables are capable of handling the current (15A min. recommended)
Ensure the POWER (5) is switched off until all input and speaker connections are in place.
The RS605 is designed to accept up to 5 line inputs from a mixer or multiple input sources and
provide power for up to 5 independent speaker zones from its 5 internal amplifiers.
Line level signal inputs should be connected to the dual RCA INPUT connectors (12) at the rear.
Each of the 5 amplifiers are mono, so any stereo input signals will be summed together to provide a
monaural output.
A Mode switch (9) offers the option of independent input to each amplifier (5CH) or a mix of all
inputs to all amplifiers (MIX)

Speaker outputs

Each of the RS605 amplifiers can be used either as a 100V line amplifier or standard low impedance
power amplifier. These 2 configurations cannot be used together, so it is important to decide which
method will be used at the start.
The RS605 speaker outputs are via modular connectors with screw terminals. These modular
connectors may be unplugged from the rear for convenience during installation.
Information about the differences between 100V and low impedance systems are detailed on the
following pages.
