Adjust the sound using the MID-TREBLE and MID-BASS sliders and BASS control on the

901

active equalizer. Use the tone controls on your receiver only after the MID-TREBLE and

MID-BASS sliders have been set according to the procedures below.

These controls let you make adjustments to compensate for the effects of speaker location,

room acoustics, and program quality.

1. Select a familiar musical piece.

2. Set your receiver tone controls to the center (ﬂat) position. If it has a loudness compensa-

tion control (marked LOUD or LOUDNESS), set it to the OFF or OUT position.

3. Set the MID-TREBLE slider on the equalizer to its center position.

4. Play the selected music through the 901 speakers at normal volume. Move the MID-BASS

slider back and forth several times and listen to the effect. You should hear a signiﬁcant

change in the fullness of the sound. If you do not, the active equalizer may not be engaged.

Refer to Playing your speakers on page 14.

5. When you are familiar with the effect of the MID-BASS slider, set it to the extreme left. Start

the musical passage again and slowly advance the MID-BASS slider to the right until the

sound is rich and full, without excessive heaviness.

6. Replay the musical passage, this time moving the MID-TREBLE slider back and forth to

become familiar with its effect. You should hear a signiﬁcant change in clarity of the sound.

7. Set the MID-TREBLE slider to the extreme left and play the passage again. Slowly advance

the MID-TREBLE slider to the right until the sound is clear and detailed without excessive

shrillness.

The Bass control provides an alternate bass equalization. It is not a bass enhancement switch,

and it is not intended to boost the bass output of the speakers.

Press the BASS control IN (to position 2) to engage an alternate form of equalization that

changes the way the speakers handle low-frequency information. For example, you may

prefer pipe organ music with the alternate equalization. The control can also be useful in

eliminating feedback or rumble from a turntable.
