4.4 Powering up the mixer
The Qu mixer has an internal universal voltage power supply
unit. This means you can use your mixer in most parts of the
world without the need to modify the unit as long the local
mains supply is within the range:
Mains Voltage = 100 to 240 V.AC
Mains Frequency = 47 to 63Hz
Important - Before starting, read the Safety Instructions
Sheet packed with the mixer. These can also be
downloaded from the Allen & Heath website.
Also read the safety notes printed on the rear of the mixer.
AC MAINS IN
– Standard IEC socket for connecting the
mixer to the local mains supply. Plug in a mains lead with
moulded plug suitable for your territory. A suitable mains
lead is shipped with the mixer.
Note – Do not replace the mains plug or modify the lead in
any way. For your own safety and that of the operator and
performers do not remove or defeat the ground connection.
A cable clamp is provided. You can slot the cable into this
or lock it in place. To lock the cable use a star head Torx
T20 screwdriver to refit the clamp around the cable.
Fuse
– Mains input fuse to protect the mixer circuits in the
unlikely event of a failure or excessive power surge. If you
need to replace the fuse always use one of the same type
and rating as printed on the rear panel. If the replacement
fuse blows then refer to your authorised Allen & Heath
service agent for advice.
