Step 5

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

• If using very short output cables, make sure that the pots are in

the unity gain position; that is, with the arrow on each pot pointing to the dot beside or above it.

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.

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 table top.

Connection diagrams

Setting Up Potentiometers for Cable Lengths

To set up your DA AV EQ, you may need to adjust the potentiometers for the cable lengths of the outputs. You can make the necessary adjustments using an Extron Tweeker (small screwdriver).

Settings for short cables

At the factory, the DA AV EQ pots are set precisely to the unity gain position (with the arrow on the pot pointing to the dot beside or above it). If you are using very short output cables, do not turn these pots; leave them at the factory default setting. If the pots have already been turned, reset them to the default position. The illustration below shows outputs 1 and 2 set to the unity gain position.

Gain and Equalization Controls

Gain and equalization (EQ) can be adjusted from the front panel of all DA AV EQ series products except the DA 6A and DA 3AV RCA. On S-video models, you can adjust luma (Y) gain and equalization, and chroma (C) gain. On composite video models, you can adjust Gain and EQ. Adjustments are made for each pair of outputs.

The front panels of all the DA AV EQ series products feature Gain and EQ potentiometers (pots), which enable you to make the gain and equalization adjustments. Each pot has a white dot either above it (composite and Y gain) or to the lower left of it (EQ and C gain). These dots indicate 0 dB unity.

Use an Extron Tweeker or a small screwdriver to rotate these pots clockwise to increase gain or equalization, or counterclockwise to decrease.

The DA AV EQ products have one EQ pot and one or two Gain pots for each pair of outputs. Therefore, gain and equalization can be adjusted only for a pair of outputs at a time. For example, if you adjust the equalization pot for output 1, output 2 is adjusted by the same amount, at the same time.

This means that you should have cables of the same length for both outputs of a pair.

• DA 6V EQ, DA 6AV EQ, DA 6AV EQ RCA, DA 8V/4V Dual EQ, and DA 12V/6V Dual EQ: The front

panels of these models feature one Gain and one EQ pot for each pair of outputs. The illustration below shows the Gain and EQ pots for outputs 1 and 2.

Adjusting for long cables

If you are using long cables, you will need adjust the Gain and EQ potentiometers (pots) until you have the best picture quality. Using an oscilloscope is recommended; however, you can make these adjustments without one. Both methods are described below.

Adjusting with an oscilloscope

1. Feed a grayscale signal from an Extron VTG 300/400 or

other A/V test generator to the input of the DA AV EQ.

2. Remove the far end of the output cable from the display,

and connect it to the oscilloscope with 75 ohm termination.

3. Adjust the composite video or Y Gain pot to achieve 0.7

Vp-p for the white bar of the test pattern. For the S-video models, adjust the C gain pot to achieve 0.3 Vp-p of color burst level.

4. Adjust the EQ pot until no overshooting or round corners

appear on the test pattern.

5. Repeat steps 1 through 4 for all other output pairs.

6. Plug the far end of the cable back into the display device.

Adjusting without an oscilloscope

1. Feed a grayscale signal from an Extron VTG 300/400 or

other A/V test generator to the input of the DA AV EQ.

2. Adjust the composite video or Y Gain pot until the picture

from the display device appears to have the correct brightness and contrast.

3. Adjust the EQ pot until the picture appears sharp and

without visible smearing.

4. Repeat steps 1 through 3 for all other output pairs.
