Remote Control Functions

When using the latest discrete digital electronics we recommend

setting the subwoofer amplifier's BASS LEVEL control to its THX/

REF position and using the Processor/Receiver's built-in subwoofer

level control. Should you have difficulty achieving the correct

subwoofer volume this way or should your Processor/Receiver not

have a subwoofer level adjustment built in, you can use the subwoofer

amplifier's main BASS LEVEL control to make this adjustment.

Level Setting Without an SPL Meter

If you decide not to use an SPL meter try to set all the speaker levels

the same using the Test Tones. Of course, this will be much more

difficult without the meter, especially for the subwoofer.

Setting the Subwoofer Level Without an

SPL Meter or Test Tones

Start your listening with the subwoofer LOW PASS control set at the

correct crossover point (or in the THX/EXT position if you're using

a THX Certified processor or unit with a built-in crossover). Set the

PHASE control to 0 , and the front panel BASS LEVEL control to the

Receiver's level control up until you just start to hear the subwoofer

working. Now, from your normal listening position, determine

whether the subwoofer is playing loudly enough and filling in the

bass frequencies of the music evenly. If adjustment is necessary,

change the processor's setting or use the front panel BASS LEVEL

control if your processor lacks a subwoofer level adjustment.

How Much is Enough?

Sometimes people prefer more bass impact for movies than sounds

natural when reproducing music. Since you have the 4 EQ settings

plus the LEVEL TRIM, it's now a snap to adjust the subwoofer to

compensate for any variations in the source material. Remember

however, the most common error people make when setting up their

system is to play the subwoofer (and surrounds) too loudly. Should

you desire the most accurate overall reproduction, a well balanced

sound from deepest bass to highest treble is the best way to get it.

Have fun. Experiment. Enjoy.

Remote Control Functions

There are 4 custom EQ settings that have been programmed into

your subwoofer amplifier (see graphs on back cover). These have

been chosen to enhance your enjoyment of both movies and music.

These EQ settings are fairly subtle, as we wanted to make them truly

useful with a wide selection of software. They are accessed by using

the four EQ buttons on your Remote Control.

make individual bass notes easier to hear as well. EQ1 can also be

used to remove some "boominess" from the bass when playing par-

ticularly bass heavy material.

EQ2 This EQ was programmed to enhance the impact and "punch"

of special effects. It consists of an increase in the bass response cen-

tered around 60Hz. Depending upon the source material, EQ2 could

also be used to fill in a bass shy music recording.

EQ3 Another choice primarily intended to enhance movie and video

soundtracks. This one uses a more subtle increase of bass output

centered at 80HZ with the addition of a very low frequency filter.

This gives you the option of punching up the mid-bass while at the

same time reducing the possibility of overdriving the woofers with

extreme low frequencies.

amplifier indicates the level of adjustment numerically.

Pressing the MUTE button turns off the volume of the subwoofer.

Pressing it again returns the volume to its previous setting.

Direct Access Connector

Located on the rear panel, this port and the corresponding male

plug (included and installed in the port) is for use with a hard wired

remote control system using electronic or mechanical switching.

Each contact function is labeled. To access the control functions use

a normally open connection. Momentary closure will activate each

function. The LEVEL TRIM function will respond in 1dB steps to a

single contact closure while constant closure will result in continu-

ous steps to the maximum of + or – 10dB. The REF EQ and REF

volume reset functions each have their own set of contacts.
