TOA E-04R User manual

EQUALIZER MODULE E-04R, E-05R, AND E-06R
Attention: This module has been designed for use with TOA 900 Series
Mixer/Amplifiers and Power Amplifiers. Use with any other equipment
may result in damage to the module.
E-04R/E-05R/E-06R Equalizer Module General Information
The E-04R/E-05R/E-06R module provides the proper equalization for TOA model H-1/H2 (WP)/H-3(WP) loudspeakers. It is designed to be installed in TOA 900 Series modular
mixers and amplifiers (MK2 or A series) and derives its power from that unit. Through the
use of the dual RCA cable provided, signals are routed from the preamplifier output to the
module input, and from the module output to the power amplifier input. In this way, the
proper equalization is introduced into the signal flow just before it reaches the power
amplifier stage.
Materials Provided
The E-04R/E-05R/E-06R is supplied with this instruction sheet, a dual RCA to RCA cable
and two securing screws.
Installation
1. Make sure that the power switch on the mixer or amplifier is off.
2. Select a port on the amplifier for the module. If there is a blank cover over the port,
remove it.
3. Taking care in handling to avoid static damage to the E-04R/E-05R/E-06R, insert the
module fully into the selected port and secure with the screws provided.
4. Connect the PRE AMP OUT of the mixer or mixer/amplifier to the module INPUT.
Connect the module OUTPUT to PWR AMP IN (power amplifier input).
5. Switch on the mixer or mixer/amplifier and check for proper signal flow through the
module.
Note that the volume control for the input port in which the E-04R/E-05R/E-06R module is
installed has no effect.
When using this module with a 900 Series Power Amplifier or with an A-901A 10 watt
amplifier, the unbalanced audio signal from the mixer or other source, is fed to the INPUT
jack of the module. Through the use of a suitable short cable, connect the module
OUTPUT to the input terminal block of the power amplifier or the program input of an A901A.
Jumper Wire Setting
Cut J1 on the board to suppress the low
frequency boost when using a subwoofer
system.
