Power Supply
MODEL 1.4 is powered by an external 90W 24V universal voltage PSU. There are many advantages to powering the mixer
in this way, rstly it frees up internal and rear panel space for extra circuitry for greater funconality in a compact format,
it reduces heat build up inside the mixer, it removes the danger of electrical shock in case of liquid spills, and it virtually
eliminates mains hum elds for beer noise performance.
Internally, the 24 volts from the external supply, is converted to just under +/- 20V for the analogue power rails using
high frequency switching technology, giving MODEL 1.4 some of the highest signal headroom of any professional mixer,
irrespecve of its applicaon.

The power supply shipped with the MODEL 1.4 has been carefully selected to
ensure reliable operaon over extended periods, and in most environmental
condions - do not use any other type of supply as it could damage the mixer or
impair its performance.
When connecng the PSU to the mixer, ensure that the FLAT face of the plug is
towards the le, looking from the rear. Make sure the pins are lined up and
push the plug fully into the socket unl it latches. This is a locking connector
and is released by pulling back the spring loaded sleeve on the plug, which
allows the lock to release. NEVER unplug the connector by pulling on the power
lead as this could damage the locking mechanism.
Make sure the rear panel POWER SWITCH is in the OFF posion before
connecng or disconnecng the power supply.
