Rack Mounting; Setting The Mode Switches; Setting Clip Limiters - QSC Audio RMX 4050HD Manual Del Usario

RACK MOUNTING

Use four screws and washers to mount the amplifier to the
equipment rack rails. To use the amplifier outside a rack,
attach the self-adhesive rubber feet to the bottom. Use the
rear rack ear support kit to support the rear of the amplifier for
portable use.
EN
When installing equipment into a rack,
distribute the units evenly. Otherwise,
hazardous conditions may be created by
an uneven weight distribution.
COOLING
Air flows from the rack, into the back of the ampli-
fier, and out the front. This keeps the rack cool. The
fan automatically runs faster when the amp is work-
ing hard.
Do not block the front or rear air vents!
AC MAINS
Connect AC power to the IEC socket on the back of
the amplifier. NOTE: Turn off the AC power switch
before connecting AC power.

SETTING THE MODE SWITCHES

The RMX 4050HD and RMX5050 have Mode
switches for Stereo, Parallel, or Bridge Mode. Addi-
tionally, each channel has independent Clip Limiting
and Low Frequency (LF) Filtering.

SETTING CLIP LIMITERS

Each channel has a Clip Limiter with its own on-off
switch. The limiter only responds to actual clipping,
and automatically compensates for load and voltage
variations. Clip limiting is generally recommended,
especially to protect high frequency drivers.

Air flow in QSC amplifiers: Cool air is drawn into the
rear of the amplifier by the cooling fan. Warm air exits
the front of the amplifier.
The correct AC line voltage is shown on
the serial number label, on the rear
panel. Connecting to the wrong line volt-
age may damage the amplifier or
increase the risk of electric shock.
Set switch to the right to use Clip Limiting.
Switch 1 controls Channel 1.
Switch 10 controls Channel 2.
