Chapter 3: Installation

Units shipped to the USA include a 120 VAC power supply. Contact the factory if you
require a different power supply.

The section Section 3.1

Bench Tests Before Installation

is intended for experienced

technicians to test the Model E prior to installation. Those without test equipment can
begin in

Audio Wiring

on page 14. In either case, we recommend placing the Model E

in a convenient place in the mixer’s line of sight. Rack ears can be removed.
