POWERING
The mixer may be powered from either internal cells or an external DC power source.
The integral battery compartment requires a total of 6 size-AA cells. Access is
gained via a captive lid which is retained by one 90-degree-turn buckle. The lid
hinges outwards from the bottom panel. When installing new cells please ensure
they are inserted with the correct polarity rotation.
Either conventional dry or rechargeable nickel-cadmium cells may be used.
However, no recharge facility for ni-cads exists within the mixer. This must be carried
out externally.
When driving the mixer from an external power source, PIN 1 is the 0V connection
and a voltage in the range +9V to +15V DC should be supplied to PIN 4. The power
source should be capable of delivering approximately 400mA - allowing some
capacity for phantom powering.
If an external power supply unit (PSU) is to drive the mixer, a current capability of at
least 400mA is required. It is poor practice to run a PSU at its limit; therefore we
recommend a minimum of 600mA.
Audio Developments AD100-15 PSU is a suitable unit.
WARNING: When NOT using the PSU (AD100-15) supplied for the mixer, ensure
your 4-pin XLR is correctly wired to match the POWER IN connector. Failure to do
so may result in the breakdown of the internal DC-DC converter. Make this check
even if using a PSU which may have been supplied to you in the past, eg AD100-06.
