OPERATING INSTRUCTIONS
INTRODUCTION
The 4400 and 4800 Series mixers are the most truly automatic mixers available. Once
set up for an application, their proprietary circuitry functions automatically as if a trained
operator were at the controls, requiring little or no operator intervention. This automatic
operation, previously available only in the 4000 Series Automatic Mixer System is now
within the reach of smaller applications such as churches, meeting facilities, court-
rooms, council chambers, and any application requiring up to eight inputs.
The configuration of the system and setup of the options is described in the installation
instructions, Section 4 Group 20 Sub B. This document describes the operation of the
operator controls and indicators for the 4400 Series and 4800 Series Automatic Mixers,
all of which are located on the front panel.
The gating sensitivity of the gated inputs is independent of the front panel level control
setting, making level setup simple and straightforward. Set the Output control(s) at the
mid to
to the desired level. Finally, adjust the overall level with the Output controls.
