The REQ-2.2 uses discrete Class A audio amplifiers and these along with the
power supply generate a fair amount of heat. Whilst the casing has many
ventilation holes, care should be taken to avoid racking the REQ along side
other units that run hot. If possible, allow ventilation space between the
REQ and other hot running boxes.
If the REQ becomes too hot, internal parameters may change and this may
show up as clicks when switching the EQ bands in and out.
The REQ also uses wound chokes (inductors) and because these are coils of
wire with many turns, they are prone to picking up mains hum and other
noise in the environs. The REQ chokes are contained within steel housings
to minimize hum induction, however avoid mounting the REQ next to
devices with large unshielded power transformers or switching power
supplies.

As a safety precaution your REQ maybe shipped without a mains fuse fitted.
Before use, you must select the correct mains voltage for your local supply
on the rear panel and fit the correct mains fuse type into the fuse draw for
that voltage.
The factory or your dealer may have already set all this up for you but it
pays to check it before powering up the REQ.
