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. 

The SubRosa EQ system can auto-

matically adjust for the effects of room 

EQ. It measures the actual frequency 

response using the supplied measure-

ment microphone. Then it automati-

cally compensates for peaks or dips and 

smooths out the response.

For best results it is recommended that 

the subwoofer crossover in your receiver 

or processor be set to its maximum set-

ting (or “bypass”). This ensures that the 

subwoofer will be properly matched to the 

rest of the speakers in your system.

The following procedure will help you 

start the automatic equalization:

Automatic EQ Mode

1.  Install the subwoofer in the best location 

you can find, using the procedure on the 

previous page.

.  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. 

Room Equalization Procedure

Have the kids play in the backyard and 

give the dog a treat to stop him 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.

4.  Plug the microphone into the subwoofer 

amplifier's microphone jack. 

5.  Set these controls:

•  Volume to 0 dB.

•  Crossover to "Bypass."

•  Phase to "Normal." 

•  Equalizer Authority to "Normal"

6.  Turn on the amplifier's power switch 

and press the Start button to go from 

standby to play mode. Press Start again 

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 

flash randomly for a while, then the pairs 

will gradually glow constantly as each 

band is measured (from left to right). 

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.
