1. If you have not already done so, attach the Calibration Microphone included with the AS-EQ1 to the jack labeled

Cal Mic Input on the front panel (behind the magnetically attached faceplate) of the AS-EQ1. DO NOT use the

microphone supplied with your AVR or Pre/Pro or any other microphone as it may produce inaccurate results.

2. Place the AS-EQ1’s Microphone in your main listening position at ear height, with the tip of the micro

phone pointed at the ceiling. Press Measure. This first measurement is used for both room equalization

measurement and calculating the distances to each speaker for setting the delays.

3. After the first position is measured, the AS-EQ1 needs to measure other positions in the room (minimum of three)

around the listening area. These do not necessarily have to be in each individual seat (see below). You should

measure a minimum of 8 locations within the listening area in order to provide the AS-EQ1 with sufficient

information about the room acoustics so it can develop an optimal EQ solution for all listening locations. If

you use the best practices below, this will give 2 – 3 measurements per seating position for a total of 12 – 24

measurements for an average sized room. For a large room you might want to take the full 32 measurements for

optimum results.

4. After completing taking your measurements, click the button to continue to the next task “Detection Results”.

If you had previously set your Left/Center speaker to Large, you should now set it back to Small.

Calibrating the AS-EQ1 in Your Listening Environment

The best practice is to take two measurements at each seating position, one at normal ear height and the other
a few inches lower to represent a shorter and/or slouched listener. You can also take two measurements at ear
height in the approximate position of each ear. Keep the microphone tip at least a few inches away from the
seat back. If there are also positions where people may be standing for part of a presentation, those locations
can be measured as well. Do not take measurements in locations where no one will normally be listening. You
may take up to 32 measurements in total.
