Datasheet

For the best possible performance, your AV receiver needs to be calibrated and the system fine tuned.

Follow the instructions included with your AV receiver on how to calibrate your system.

Fine Tuning

The four steps necessary to properly fine tune your system with Monster THX Select Certified Speakers are, in order:

1. Phase Correction (Polarity)

2. Levels

3. Distance

4. Equalization

Phase Correction (Polarity)

First, verify the correct polarity of all speakers. If one speaker is out of phase, it may be difficult to catch—but phase

effects on high performance audio are critical. Any speakers out of phase will affect directionality, soundstage and

bass impact, distort ambiance, and dull the impact of your favorite music and movie audio.

Triple-check all speaker cables for correct polarity. To accurately check polarity, Monster recommends the use

of an electronic polarity checker to verify that speakers all have the same polarity.

Levels

Setting output levels is crucial for the optimal performance from your Monster THX Select Certified speaker system.

Follow these guidelines and the owner’s manual included with your AV receiver.

• Select a manual test tone if available.

• Sitting in the sweet spot (central listening position), hold a dB meter (commonly found in electronics

specialty stores) in front of you facing upwards with the mic about ear level.

• Adjust each channel output until 85 dB is reached on the dB meter.

• If the dB meter jumps around or the sound is not quite right, listen to music and movie cuts

and adjust the levels accordingly.

Distance

Setting speaker distance to your AV receiver is crucial for proper performance. Measure the distance

to all speakers accurately and set your AV receiver accordingly.

Equalization

Although there is no such thing as a perfect room, with proper tuning you can make any room sound good.

Some rooms have “room nodes” which cancel the response of even the best speaker.

Monster recommends running a modified “Auto mode” equalization. If available on your equipment, run

the auto-equalization routine then fine tune it by ear (some auto-modes make a room sound too bright).

If you’re not sure how to perform this procedure and you are using good speakers, just equalize for mid-bass

or skip the “Auto Mode” altogether.
