Introduction

About this Manual

This manual provides information on the Extron DA AV EQ series of audio/video distribution amplifiers and discusses how to install and operate them.

The terms “DA,” “amplifier,” and “distribution amplifier” are used interchangeably to refer to any of the models in the DA AV EQ series.

About the DA AV EQ Series

The Extron DA AV EQ Series products are high-performance composite video or S-video distribution amplifiers with audio. Models with audio only and video only are also available. The DA AV EQ series amplifiers feature long cable drive capability and individual gain and equalization adjustments (for every two outputs) to optimize the picture for displays that are located at significantly different distances from the DA.

Models

The DA AV EQ Series consists of the following 10 models:

DA 6V EQ — One input, six outputs, composite video with equalization and gain controls

DA 6AV EQ — One input, six outputs, audio, and composite video with equalization and gain controls

DA 6AV RCA EQ — One input, six outputs, audio on RCA connectors, and composite video with equalization and gain controls

DA 6SV EQ — One input; six outputs; S-video with luma (Y) equalization control, and luma and chroma gain controls

DA 6SVA EQ — One input; six outputs; audio; and S-video with luma (Y) equalization control, and luma and chroma gain controls

DA 6SVA RCA EQ — One input; six outputs; audio on RCA connectors; and S-video with luma (Y) equalization control, and luma and chroma gain controls

DA 6A — One input, six outputs, audio only

DA 3AV RCA — One input, three outputs, audio on RCA connectors, and composite video

DA 12V/6V Dual EQ — Dual composite video DA that can function as either a 1-input, 12-output DA with one active loop-through, or two 1-input, 6-output DAs in one enclosure (no loop-through); equalization and gain controls

DA 8V/4V Dual EQ — Dual composite video DA that can function as either a 1-input, 8-output DA with one active loop-through or two 1-input, 4-output DAs in one enclosure (no loop-through); equalization and gain controls

Features

Equalization and gain control — Independent gain and equalization control for each two outputs provides more flexibility and more accurate cable compensation to drive different lengths of cables from different outputs. (S-video models have Y-only equalization, and Y and C gain controls.)

Outputs with similar lengths of cables should be paired in the same output group so that they can share the same gain and EQ setup.

Passive video loop-through— All models except DA 6A, DA 12V/6V Dual EQ, and DA 8V/4V Dual EQ feature a passive video loop-through channel with a 75 ohm impedance toggle switch, which provides for local monitoring and cascading to another distribution amplifier.

Power supply — An internal 100 VAC to 240 VAC, 50/60 Hz, autoswitchable power supply is provided on all models.

Enclosure — All models have a compact 1U, half rack enclosure, six inches in depth.

High bandwidth — Bandwidth of 150 MHz @ -3 dB for composite video and S-video maintains signal quality without picking up noise.

Rack and furniture mountability — All models can be mounted on a rack shelf, under a desk or podium, or through a desk or table top.
