User's Manual

1. Standby LED and

2. Power Switch

Press the power switch in to turn on

the amplier. As a general rule, turn it

on after your preamplier or receiver

is turned on. When you have nished

listening for the night, turn it off before

your preamplier or receiver.

After a period of inactivity (i.e. with no

input signal), the amplier will automati-

cally turn itself to Standby mode, where

it is effectively off. It can however, turn

back on automatically when an audio

input signal is present, if a 12 VDC

trigger voltage is applied to the Trigger

inputs, or if the Start button is pressed.

3. Start button

Press this once to enter the Auto EQ

mode (if the sub is out of Standby

mode). Press and hold it down for

several seconds to enter the Manual

EQ mode. See page 12 for more de-

tails on this and the EQ controls.

4. LED display

These LEDs are used during the Auto

EQ and Manual EQ procedures.

5. Microphone Input

This is where you plug in the supplied

linear measurement microphone when

you want to use the Auto EQ mode.

(Only use the supplied microphone.)

6. Equalizer Authority

This control's primary purpose is to

adjust the EQ Authority. During normal

listening, you can adjust the overall EQ

from none (ccw, 0%), to fully equalized

(cw, 100%). For example, if your rst

band has a 6 dB boost, setting this

control to 50% would make it boost

only 3 dB.

This control is also used during the

Manual EQ mode to adjust each of the

four internal EQ bands, and allow you

to add "color" to the sound as desired.

7. Phase Control

This control changes the relative phase

of the subwoofer with respect to your

other speakers. Use this control to help

blend the subwoofer with the rest of

your system. This is accomplished by

adjusting the control in small incre-

ments as you listen for the most bass

at your listening position. As a nal trim,

readjust the Crossover Frequency and

Volume controls after the Phase has

been set.

8. Crossover Frequency

This controls the high frequency cutoff

point. With the control at the 100 Hz

mark, the subwoofer will reproduce

frequencies up to 100 Hz. If the control

is set fully clockwise, the crossover

is bypassed and the subwoofer will

reproduce a frequency range up to

115 Hz. With the control fully counter-

clockwise the subwoofer reproduces a

narrow range, up to 30 Hz.
