connectors, onboard player for MP3 or WAV audio
files, high quality effects section with 32 editable
presets, 3 Master outputs with 7-band EQ each and
flexible signal routing options, delay line for Master-B
(150 msec/50 m), headphones control, LPN speaker
processing, class-D 2 x 450 W RMS / 2 x 600 W / 4 Ω
program power, micro-controlled power supply (100–
240 V), Direct Drive option for 100 V speaker lines,
comprehensive protection package, live and install
connectivity, optional rack mount kit.
The PM 502 is an extremely versatile tool for a
multitude of live and installation applications. It will be
the ideal choice for entertainers, DJs and small bands
looking for a compact and light-weight solution for live
applications or rehearsal venues. The digital USB
interface also allows for basic recording and the
onboard MP3-Player on the front, makes background
music during breaks, a smooth and easy transition.
The input structure of the PM 502, along with the
entire feature package and connectivity, positions this
mixer at the heart of many installations ranging from
bistros, small clubs, lounges, boutiques, hotel bars
and lobbies to churches, mosques and a wide range of
similar applications.
