Introduction
Although it is neither complicated to install nor difficult to operate your matrix, a few
minutes of your time is required to read this manual for a properly wired installation
and becoming familiar with its features and how to use them. Please take care in
unpacking your mixer amplifier and do not disregard the carton and other packing
martial. They may be needed when moving or required if it ever becomes necessary
to return for service. Never install near a radiator, in front of heating vents, to direct
sun light, in excessive humid or dusty location to avoid damage and to guaranty a long
reliable operation.

Features
The PM-88 is multi zone audio matrix system.
They are intended to form part of permanent sound system in pubs, bars, restaurants, hotels,
offices, factories, terminals, stations, airports etc. where multiple audio sources are in use and
need to be easily combined with announcements and/or paging one or more zones. They are
compatible with EM series paging microphone stations up to 32 zones. Each of the output zones
volume level and music source can by controlled by remote control panel WP-8/8A. A contact
closure allows the playing of user recorded messages automatically. A built in monitor speaker allow
to hear 8 input music sources via RCA connectors. The PM-88 operate on AC100V~240V with
PFC or DC24V and packaged in 5.25" height (3RU) rack mount enclosure.
* 8 Music input and 8 outputs with full matrix.
* 4 remote microphone stations with link in and out for extension.
* A Paging microphone input with phantom.
* DRP(Digital recording and playback) up to 60secs.
* Output extension for using multiple PM-88 up to 4 units.
* 8 contact closer for playing message automatically.
* Priority: PAGING > DRP > EM > WP-8A = BGM.
* 8 BGM input indicators (-20dB).
* Easy installation with CAT-5 cable.
* Balanced output and tone controls (100Hz/10kHz).
