Aural Exciter and OPTICAL Big Bottom

4.0 Controls & Indicators

4.1 FRONT PANEL VIEW

4.2 BIG BOTTOM TUNE CONTROL

This control lets you optimize the bass enhancement frequency band. Where this is set

depends upon your sound system and the type of music being played. Typically, 12:00 is a

universal position. However, you may want to experiment with other settings. The range is

from 50Hz to 190Hz. At center, you are tuned to about 110Hz.

4.3 BIG BOTTOM DRIVE CONTROL & INDICATOR

This needs to be set at a point where the processor receives the optimum level required

for Big Bottom to work effectively. To find the optimum level, turn the control clockwise

until the green L.E.D. at the right of the Drive control pulses on the bass peaks. Longer and

brighter pulsation means a longer bass sustain is being created. You will find a range of

settings that yields very musical and powerful bass.

If the green L.E.D. doesn’t pulse by the time you reach 2 o’clock, check the Operating Level

switches on the back panel and make sure they are set properly. It’s possible that you have

set the Operating Level switch to +4dBu and you have a -10dBV input. On the other hand,

if the green L. E.D. is pulsing strongly at settings as low as 9 or 10 o’clock, you probably have a +4dBu input

level with the operating level of the 204 switched to -10dBV. That can cause overload distortion.

4.3 BIG BOTTOM MIX CONTROL

This control adjusts the amount of Big Bottom enhancement being added to the original

signal. The lower the setting, the subtler the effect until there is no effect at all. The higher

the setting, the more dramatic the effect.

One of the benefits of the Big Bottom is that it can increase the bass power without greatly

increasing the peak output level. That means that loudspeakers and amplifiers will not be

overdriven even though the bass has been extended and increased in power. Extreme set-

tings of the Big Bottom Mix control, however, will increase the peak output level signifi-

cantly, so we recommend staying within some reasonable limits.

Generally, the best results are found between the 9 and 2 o’clock settings. Try working the Big Bass Tune, Drive,

and Mix controls when maximizing the bass enhancement.
