Room Equalization (EQ) Procedure

Subwoofer performance is greatly af- fected by the room in which it is situated, and the positioning within the room. The room effects will boost and cut the output levels reaching your listening position. This gives a "Room EQ" effect which can often be far from wonderful.

4.Plug the microphone into the subwoof- er's microphone jack.

The SunÞre True Sub EQ can automati- cally adjust for the effects of Room EQ. It measures the actual frequency response using the supplied measurement micro- phone. Then it automatically compen- sates for peaks or dips and smooths out the response.

The following procedure will help you start the automatic equalization:

Automatic EQ Mode

1.Install the True Sub EQ in the best loca- tion you can Þnd (see previous page).

2.The calibration must be done while the listening room is quiet. Please turn off any noisy machinery, including heating or cooling systems during this process. Have the kids play in the backyard and give the dog a treat to have him stop barking. A small amount of noise, such as quiet talking or whispering, is OK.

3.Place the microphone in the listening position (on the couch, for example), pointing in the direction you’ll normally be facing while listening to your system. Only use the microphone supplied by SunÞre.

5.Set these controls:

•Volume to 0 dB.

•Crossover to "Bypass."

•Phase to "Normal."

•Equalizer Authority to "Normal"

6.Turn on the subwoofer AC power switch and press the Start button to go from standby to play mode. The yellow LEDs should light up. Press Start again, and hold it a moment to start the calibration.

7.The subwoofer will generate a test tone sweep, slowly increasing up the fre- quency scale; the microphone will take measurements of the sound arriving at your listening position. The LEDs will ßash randomly for a while, then the pairs will gradually glow constantly as each band is measured. This sequence will repeat twice until the measurements are complete. The LEDs will all blink once and stay on, and the test tones will stop.

If you Þnd that the Þrst test tone plays louder and louder, and never leaves the Þrst band, then either the microphone is too far away from the subwoofer, or it is not plugged in correctly.

8.The procedure may take several minutes. Do not make any loud noise during this process, as it may affect the accuracy and/or make it take longer.
