A BRIEF TOUR OF THE 24XS

The Outside

OUTPUT LEVELS CONTROLS- These variable gain

controls adjust the high pass and low pass output levels indepen-

dently.

WAVE ALIGNMENT CONTROL- This control adjusts how

much the sound of a speaker is shifted. The internal switches

select whether this leans toward the high pass or low pass.

OUTPUT STATUS LEDS-

POWER: Shows when the 24XS is turned on (need we say

more?)

INPUT MAXIMIZED: Shows when the input levels are

within 3dB of clipping,

5 VOLT: Shows when the output levels are at five volts (make

certain your amplifier can handle this much input)

2 VOLTS: Shows when the output levels are at two volts (this

is a common input level for most amplifier manufacturers. Don't

guess on this, check your amp's owners manual to be certain.)

SPEAKER WAVE ALIGNMENT BUTTON-

Bypasses the speaker wave alignment circuitry for simple

comparison of with versus without.

POWER CONNECTOR- A wonderful, removable connector

that allows you to hook up all the power wires in the convenience

of daylight and then plug them into the 24XS in the dark recesses

of your trunk.

The Most Important Instruction of all

FILL OUT AND SEND IN YOUR WARRANTY CARD!

Also, save your invoice or sales slip as proof of purchase. These

actions will protect your investment and help prove that you really

owned such a great piece of audio gear in case somebody takes a

liking to it while you're tanning in Cabo.

Important

For the best product performance and the lowest use of Tylenol,

nothing is better than a professional system installation. Your

AudioControl dealer has the training and equipment to take care

of the job quickly and to get the best sound out of your system. If

you are a solid do-it-yourselfer then this manual should give you

all the information you need to successfully make music with the

24XS. Happy Listening.

Features

Programmable 24dB/Octave 2-way Crossover

With module programmability, the two way electronic crossover

in the 24XS can be matched up to any stereo system. By simply

changing a resistor module, you can select almost any crossover

frequency imaginable. The 24dB/Octave Linkwitz-Riley (a couple

of real nice audio engineers) design is normally reserved for the

best home and professional systems, but now this state of the art

crossover is yours also.

Programmable Frequency Match (PFM) Filter

This module programmable low cut filter allows the system

designer to custom tune the bass response of the speaker system.

Smaller woofers can be protected against the voice-coil-charring

bass they are too small to reproduce. Tuned (Ported) subwoofer

enclosures benefit by having the frequencies below their tuning

cut off to reduce distortion and save system power.

Speaker Wave Alignment Technology (SWAT)

Speakers in a car stereo system have a lot to put up with;

different types of cars, different placement of speakers, different

brands of speakers. All of these things add up to a difficult time

for any installation. The Speaker Wave Alignment control takes

care of one of the most annoying (and hardest to fix) problems

with a turn of a knob: sound cancellation between speakers at the

crossover point. By allowing you to move the cancellations away

from the listener, the frequency response is smoothed out without

wasting a huge amount of the system's power trying to fill an

acoustical black hole.

The Inside

PROGRAMMABLE CROSSOVER MODULE-

This 16 pin resistor module controls the crossover frequency. It

is set from the factory at 90Hz. Different modules may be

obtained from your dealer or custom built yourself. See the section

on Making Your Own Modules for instructions. Note: The 24dB

crossover module is different than the 18dB PFM frequency

module.

PROGRAMMABLE FREQUENCY MATCH (PFM)

FILTER MODULE-

This 14 pin Module controls the cutoff frequency for the PFM

Filter. The PFM is the bottom limit for the low pass output. It is

set from the factory at 33 Hz.

SPEAKER WAVE ALIGNMENT SELECTOR SWITCHES-

This pair of switches select whether the SWAT control moves

the nulls in your speaker response towards the outputs on the high

pass side or the outputs on the lowpass side. NOTE: Both of these

switches MUST be in the same position (i.e. both in Hi or both in

Low)

GROUND ISOLATION SELECTOR-Allows the installer to

change the power supply ground isolation for different systems.

This is shipped in the fully isolated position from the factory. The

other selections can help if you have a ground loop noise in the

system that doesn't seem to want to go away.
