User's Manual

1.  Standby LED and 

 

.  Power Switch

Press the power switch in to turn on 

the amplifier. As a general rule, turn it 

on after your preamplifier or receiver 

is turned on. When you have finished 

listening for the night, turn it off before 

your preamplifier or receiver.

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

input signal), the amplifier 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 1 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 1 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 first 

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 final 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.
