Solution The electronic bass trap offers a

precise tool to attack the very worst problems with a high
degree of effectiveness in a fraction of the space occu­pied by passive bass traps. It also offers a practical low
cost solution to existing rooms where problems are pre­sent and room re-design or large passive absorbers are
not an option.

The E-Trap™can be viewed as an electronic acoustic
absorber. It incorporates a feedback control scheme into
a loudspeaker making the speaker exhibit the same
dynamics as that of a reactive absorber. It employs a
microphone, E-Trap™circuit module, tuning controls,
amplifier, speaker and the room to create a real time
active electronic acoustic feedback circuit. This active
feedback adds damping to a room mode at the tuned fre­quency. Because it is active it is capable of adding con­siderable damping to a room and still be very small in
size. The small size allows the designer to place it in
acoustically strategic locations without effecting the
rooms upper frequency characteristics and with minimal
impact to floor space and cosmetics.

The E-Trap™offers precise tunability of two well separated
target frequencies simultaneously. The frequency and
amount of damping is adjustable via controls. PC mea­surement software for Windows®is included with the
E-Trap™to allow the user to pinpoint the frequency that
requires damping. Once the E-Trap™is placed and tuned,
it requires no additional attention.

While not likely to replace all passive bass trap imple­mentations, the precision, ease of tuning and small size
offered by the E-Trap™provides an additional tool to
absorb low frequencies and can provide a dramatic
improvement in the sound of the room.

Feedback:

This controls the amount of damping effect. This can be thought of as the
gain of the feedback. Turning the control clockwise increases feedback.
(Note: feedback is how the E-Trap

™

works. This should not be confused with
instability, which is commonly called feedback in PA systems when a mic is
turned up too much. Instability occurs when there is too much feedback for
a given situation.

Contour:

This controls both feedback and the Q of the
damping effect. Turning the Contour clockwise will
increase feedback and narrow the Q. (Note:
the range of the Q is from narrow to ver y narrow.)

Frequency:

Frequency range is from 20 Her tz, fully counter
clockwise to 65 Hertz, fully clockwise.

Note: Look at the calibration on the data sheet to
approximate knob location in between 20 Hertz and 65 Hertz.

Fine Frequency:

Approximately 2 Hertz difference between fully
counter clockwise and fully clockwise

On/Off: Turns on and off damping for mode 1

On/Off: Turns on and off damping for mode 2

Switch Mic A/B:

Selects active microphone. Mic A is on the back
plate next to this switch. Mic B is on the front
plate above the speaker.

Test: No user function, for manufacturing use
