GETTING TO KNOW YOUR ESP-2

Well, maybe not personally. But on a first-name basis, anyway.

The ESP-2 Main Chassis. The first thing you notice is that there aren’t many

controls on the ESP-2 Main Chassis; just some set and leave it Spatial Restoration

tone controls. That’s because the main knob is on the Dashboard Restoration

Control Unit.

Along one side of the Main Chassis, you’ll see the Ground and +12 Volt

terminals for power, and a terminal for remote activation of the ESP-2 when your

head unit is turned on. On the other side of the Main Chassis are:

1. Left & right INPUTS

2. Left & right “THRU” outputs - (we’ll explain this one later)

3. Left & right RESTORED OUTPUTS

4. A socket for the Dashboard Restoration Control’s remote connection.

On the top surface of the ESP-2 is:

1. A power LED. It’s handy for determining whether your power connections

have been made correctly or as a very dim reading lamp if you like to hang out in

your trunk.

2. BASS, MIDRANGE and TREBLE spatial restoration tone shaping adjust-

ments.

The Dashboard Restoration Control Unit. The control portion of the ESP-2

consists of a rotary SPATIAL Enhancement Control and an LED which tells you

when the ESP-2 is operating. You must pull the knob “OUT” to turn on the ESP-2

restoration circuitry.

The SPATIAL Enhancement knob controls the restorative action of the ESP-

2’s circuitry. The farther to the right it is turned, the greater the effect of the ESP-

2. The best way to find the optimum setting for you and your system is to experi-

ment.

HOW TO INSTALL THE

AUDIOCONTROL ESP-2

Before we dig into this, we want to give Professional Installers a plug. They

can do a great job of installing the ESP-2. That’s not to say it’s not well within the

abilities of a skilled do-it-yourselfer. We’re just pointing out that installers have a

lot of experience, exactly the right tools and the ability to deal with those unpredict-

able noise bugs which slither into a lot of systems. Not to mention that having an

Authorized United States AudioControl dealer install your ESP-2 will extend your

One Year warranty to a full 5 YEARS! That said, we’ll proceed to...

A. THE MOST IMPORTANT INSTRUCTION OF ALLA. THE MOST IMPORTANT INSTRUCTION OF ALL

A. THE MOST IMPORTANT INSTRUCTION OF ALL

Fill out the WARRANTY CARD and mail it in! It’s also critical that you keep

your invoice or sales slip to establish the date when you purchased your ESP-2, and

hence your warranty. It’s also good insurance proof should a car thief take a fancy

to your system. Insurance companies are notably reluctant to believe something as

esoteric as the ESP-2 was part of a system, since it doesn’t fall into any of their little

pre-defined niches the way decks, amps and speakers do.

Placement. Theoretically, you can place the ESP-2 anywhere that it can

receive power. The most convenient places are under the dash, under the seats and

in the trunk. If possible, we suggest you mount it close to the power amplifier(s),

for ease of connecting power and remote turn-on wires. If this means trunk

mounting, be sure to read the stiff lecture on cable quality on page 8, since interfer-

ence can be induced over the long cable run between deck and ESP-2. Needless to

say, make sure you can get at the power, restoration remote, inputs and outputs.

While the ESP-2 has been designed with very rugged parts, and engineered in a

manner which reduced physical circuit board stress, be sure to consider the follow-

ing guidelines:

• Avoid mounting the ESP-2 near a heater, in front of the firewall or anywhere

else where it can get really hot.

• The mounting location must be safe from water seepage. Lots of trunks have

seal problems (poor gaskets, not sleek, furry mammals who balance beachballs and

eat mackerel at the zoo). Check for old water stains. If you find any, put the ESP-2

somewhere else or re-gasket the trunk perimeter.

• Make sure the ESP-2 can be firmly mounted without vibration. This protects

connections from breakage and stress as well as the possibility of it coming UN-

attached when you blast over a speed bump.

• Avoid any location where mounting screws may potentially pierce a gas tank

(lots of which are in the vicinity of the trunk) or gas, brake or electrical lines.
