1. INTRODUCTION

In purchasing the new EP84, you have acquired a multi-channel microphone/instrument pre-
amplifier of high class that meets the demands of the home and professional studio.
A modular designed unit, the EP84 features eight individual channels of professional quality
microphone pre-amplification in a solid 2RU rack-mountable format. Each channel features its
own level control, 20dB pad, phantom power, low-cut (high-pass) filter, phase reverse, and LED
peak level indicator. Eight professional combo connector inputs (XLR & ¼" TS) are provided on
the front panel, whilst balanced XLR and unbalanced ¼" TS connectors can be found on the
rear panel. Inserts are also provided for each other independent eight channels for simple inte-
gration of additional outboard equipment (noise gates, expanders, compressors, etc.).
The EP84 also has provision for the optional installation of SM Pro Audio's PR8IIA ADAT out-
put interface (ask your dealer!). The PR8IIA can provide users with the ability to output eight (8)
channels in ADAT optical light-pipe format. The PR8IIA ADAT output board is perfect for users
wanting to interface or add eight (8) additional channels of quality pre-amplification to a variety
of digital devices such as digital mixers, audio recording interfaces, etc.
