Toa E-07S User Manual

EQUALIZER MODULE E-07S

Attention: This module has been designed for use with TOA 900 Series

Mixer/Amplifiers. Use with any other equipment may result in damage
to the module.

Module General Information

The E-07S module provides the proper equalization for TOA model HB-1/FB-100
subwoofers. 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. Audio signals are routed
from the internal bus line to the module output after low pass filtering.

Materials Provided

The E-07S is supplied with this instruction sheet, a 3-pole removable terminal block 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.
When using the A-900A or M-900A Series, insert the module into Port 5 or 6 since the
audio signal bus lines are only connected to these two ports. (Note that the module
cannot be used in the A-901A.)

3. Taking care in handling to avoid static damage to the E-07S, insert the module fully
into the selected port and secure with the screws provided.

4. Connect the module output to the input terminal of the expansion amplifier for the sub­woofer. To convert the expansion amplifier input to balanced type, install a balanced
input module in the amplifier.

5. Switch on the mixer or mixer/amplifier and check for proper signal flow through the
module.
