Step 4

Connect the cables of the input and output devices to the
DA AV EQ, and power on all equipment.

• S-video devices are connected to 4-pin mini DIN
connectors.

• Composite video devices are connected to BNC
connectors.

Audio devices are connected to captive screw or RCA connectors.

Step 5

Adjust the potentiometers (pots) for the output cable lengths, if
necessary.

• If using very short output cables, make sure that the
potentiometers are in the unity gain position; that is, with the
arrow on each pot pointing to the dot beside or above the pot.

If the pots are already in the unity gain position (factory default
settings), DO NOT CHANGE THEM. If they are not in the
unity gain position, rotate them into position, using an Extron
Tweeker. The illustration below shows the pots for outputs 1
and 2 at the unity gain position.

• If using long cables, follow these steps to adjust the pots:

a. Supply the Color Bars test signal to the input.

(Recommendation: Use an Extron VTG 300 Video Test
Generator to generate the test signal.)

b. Adjust the Gain pot(s) for output pair 1 and 2 until the

signal level at the far end is the same as the input (or the
display shows the correct brightness and contrast).

c. Adjust the EQ pot for outputs 1 and 2 so that no overshoot

or round front corners appear at the far end on the scope
(or until you see a sharp picture with no smearing).

d. Repeat steps b and c for the rest of the outputs.

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.
