Electronic or Transformer Balanced Inputs and Outputs.

All Inputs and Outputs Individually Adjustable.

The Models 5126, 5126T, 5226, 5226T audio

distribution amplifiers are designed for use

in professional audio systems.

The application of the ADA's is found in public

address systems, communication systems, back-

ground music systems, recording systems. and

broadcast systems.

Each of the four models offers two (2) inputs

and six (6) output configurations. The 5226 and

5226T offer two identical 2x6 sections.

The Models 5126 and 5226 have state-of-the-art

electronically balanced inputs and outputs. The

5126T and 5226T have transformer isolated

inputs and outputs.

The #1 input gain stage on all four models is

adjustable from -15 to 20dB of gain. The input two

gain stage is adjustable from 0 to 20 dB of gain.

This input serves as a reference level for unity

gain, when turned completely down. Each of the

outputs has independently adjustable gain, from

infinity to 20dB of gain. Adjusting the input stage

level will effect all of the output level settings

in that section. The 20dB of gain available

at the input stage should be used before the gain

of the output section is utilized.

Each output may be strapped, via an internal

push-on jumper, to provide the input 1 signal, or,

the input two signal, or, the sum of input 1 and

2. As shipped from the factory, all outputs are

strapped to provide both the 1 and two inputs.

The power supply section of all four models has

been designed to achieve the lowest possible

noise and hum specifications. The AC transformer

is a UL recognized wall mount unit. Designing

the transformer in this manner eliminates the AC

field inside the chassis, and results in greatly

improved noise and hum figures.

The power supply section also includes a rear

mounted fuseholder, a front mounted power on

indicator (green LED), and a ground lift switch.

The switch is used to disconnect the audio

amplifier ground from earth ground, if

necessary. In almost all systems, the units will

achieve best results with the ground lift switch

in the ON position.

Each of the four models requires only a single

unit of vertical rack space. The choice of single

or dual units provides extreme circuit density in

a minimum of rack space.
