Hz Mid Bass Adjustment, Reference Settings

Parasound

120 Hz Mid Bass Adjustment:

The 120 Hz control has an adjustment range of ±8 dB and a frequency bandwidth of one-half octave. Turning this control clockwise (boosting) can add mid-bass information to speakers with smaller woofers or speakers mounted in ceilings. Turning this control counterclockwise (attenuating) can tighten up muddy bass from speakers that are mounted in corners that reinforce bass frequencies.

2.5 kHz Upper-Mid Range “Presence” Adjustment

This is the range in which your ear is most sensitive. Small adjustments will have very noticeable effects. Turning this control clockwise (boosting) adds intelligibility in acoustically absorptive rooms. Turning this control counterclockwise (attenuating) can help compensate for speakers with overly pronounced mid-range frequencies in acoustically "live" rooms.

6 kHz Upper-Mid Range “Air” Adjustment

Boosting the 6 kHz control can help add a sense of “airiness” to many recordings and can compensate for off-axis high frequency deficiencies of tweeters. Attenuating this control can help remove some digital harshness and restore proper balance in very live rooms that may accentuate high frequencies.

Reference Settings:

Once you have adjusted your R/EQ-150, use the drawings below and use a pencil to mark the optimum settings for each control knob. That way, if the R/EQ-150 becomes accidentally misadjusted, you can easily return the frequency controls to their pre-adjusted level. You may wish to copy this drawing and attach it to the unit for future reference.
