ROOM GAIN COMPENSATION

At very low frequencies, most listening rooms exhibit a rising
response known as Room Gain, as shown in Figure 16. While
many audiophiles find this effect desirable, we’ve included a Room
Gain Compensation circuit in the LE-1 that can be used to com-
pensate for this gain to achieve ultimate accuracy in most rooms.
When activated, it will equalize the low bass frequencies for a flat-
ter response and will also significantly increase the dynamic range
capability of the ULTIMA SUB-15(s), while reducing distortion.
To activate (or defeat) Room Gain Compensation:

1. At the listening position, aim the ULTIMA LE-1 Remote

Control at the ULTIMA LE-1 and press FREQ EQ once to
activate Room Gain Compensation. To defeat it, press FREQ
EQ once more.

2. Listen to a variety of sources and alternately press the FREQ

EQ button (on and off ) to judge whether to select the effect.
