Congratulations
Great attention to system design and installation makes the difference
between an average multiplex theatre and a great movie palace. When
creating your own personal movie palace experience, the choice of
components is just as critical. AudioControl knows how important the
right equipment is and for that reason we created our Home Theater
System.
This new digital audio surround system is made by the only consumer
electronics company in the world that specializes in making good
sound better. AudioControl’s passion for high quality, meticulous
attention to detail and pro sound heritage shows itself in the dozens of
awards we have won for our designs, products and service.
This manual is designed to help you get the most from the Maestro.
So, even though you’re dying to plug it in and start pushing buttons,
please take thirty minutes or so to glance over this tome and learn
about the Maestro 7.1 channel theater surround processor. Any com-
ponent that does as much as the Maestro does deserves all the expla-
nation it can get.
Most Important Instruction of All
Make certain the warranty card is filled out and mailed back to us.
Also, record the serial number and put your sales receipt or invoice in a
safe place. This is very important in the unlikely event that the Maestro
gets a sudden illness, or for proof of ownership if somebody takes a
fancy to your theater system in the middle of the night. Insurance
companies have no imagination when it comes to components like the
Maestro being part of the theater system. This concludes the nagging
section of this manual.

Key Features
AudioControl Home Theater System
The Maestro is part of the AudioControl Home Theater System. Also in-
cluded in this system are the Diva Digital Room Correction Processor, the
Avalon and Pantages High Definition Amplifiers and the Factory Certified
System Calibration. Together these components ensure superior audio and
video performance from your home theater system.
Multiple Surround Sound Formats
The powerful dual 24 bit DSP processors enable the Maestro to decode all
current consumer 5.1, 6.1 and 7.1 channel THX, Dolby and DTS surround
formats. The flash memory allows the Maestro to be upgraded in the
future when new formats become available.
Broadcast Quality Video Routing
Great sound is important, but you need a great picture also to complete a
super home theater. All video routing in the Maestro has it’s roots in
broadcast studio. With 300 MHz of video bandwidth you will see even the
finest details from the video sources even with demanding 1080i and
current progressive scan HDTV signals.
THX Ultra 2 Certified
Lucasfilm sets the standards of performance for THX certified components.
Before any home theater component can carry the THX Ultra 2 logo, it
must pass a demanding set of quality and performance tests. The THX
Ultra 2 certification ensures that you will receive superior performance
from this equipment for years to come.

Planning your installation
Connection Tips
Even if you’re an electronics veteran, this part may seem
repetitive, but some things can never be repeated too
many times.
• Don’t stand in a bucket of water when working with
electricity.
• Turn off all components before making any connections.
• When making connections, make sure that “left goes to
left” and “right goes to right.” The obvious and time-
honored way to assure this is to assign RED plugs to
Right and WHITE/GREY/BLACK plugs to the left. Yellow is
usually used for video cables or digital audio connec-
tions.
• Wherever possible, keep power cords away from signal
cables (i.e., inputs from disk players, VCRs, etc.) to pre-
vent induced hum. Bundle all power cords down one
side of your equipment cabinet and all the signal cables
down the other.
• Use high quality interconnect cables. We’re not going to
get into the debate about whether $100 per meter inter-
connects improve the sound and picture quality of your
system. We do know from experience however that
really, REALLY cheap connections can cause problems.
They tend to corrode, oxidize, and disconnect inside;
causing a hum or loss of signal. This not only degrades
the sound quality, but it will also lead to call-backs to
repair the system later.
Unit Placement
We know you’ve heard all of this before, but here goes…
The Maestro can be placed almost anywhere in your audio
equipment stack. This unit will generate a small amount of
heat during normal operation. Ensure that the equipment
location is properly ventilated. Make certain not to block
the ventilation slots on any other component. Also, avoid
placing Maestro directly over a large power amplifier. These
amps can get pretty hot and have big power transformers
that can induce hum into other audio components like
Maestro. Make certain that there is an unobstructed line-
of-sight between the location where the remote controller
sits and the Maestro front panel.

Installation
Section 2-4
Remember to consider the user when installing the Maestro
in a rack. If the primary operator is taller than average you
may want to put the Maestro and source units higher in the
rack so they can see their front panels. The same rule applies
on the shorter side. Remember, the person designing and
installing the system isn’t always the person who will be
using it on a daily basis.
Speaker Considerations and Placement
Choosing the right speakers and putting them in the correct
positions is crucial to getting the most out of a home theater
system. For the full THX surround EX playback experience,
we recommend choosing a THX certified speaker system.
Once you have decided on the speakers you are using, make
certain the Maestro is configured to match your speakers.
Front LCR (Left, Center, Right) Speakers
To present the most realistic soundstage, all three of the front
speakers must be tonally balanced. Ideally, these speakers
should be identical models. This ensures that the sound
doesn’t change as it pans across the screen. Place the speakers
at the seated ear level. Whenever possible, the three front
speakers should also be placed at the same horizontal level
for best imaging.
Side Surround Speakers
The surround speakers provide the reverberant, or ambient,
sound effects in a multi-channel theater audio system. These
speakers should be placed on the side walls approximately
36” above the seated ear height of the listeners. If you are
using surround speakers which have a dipole sound pattern
they should be mounted in-line with the main seating
position. If the surrounds are direct radiator, they should be
just behind the main listening seat.
Rear (Back) Surround Speakers
These channels are used in 7.1 mode systems to provide
extra depth in the soundfield. These speakers should be
placed approximately 36” above the seated ear height of the
listeners. These speakers should be mounted close together
(12” to 48” apart) on the rear wall of the theater facing the
screen. If you must place the speakers further apart, make
certain to change the Advanced Speaker Array setting in
the THX Setup Menu to maintain the optimum surround
sound effect.

Section 2-5
Subwoofer
The subwoofer is a large speaker that provides the bottom
end “kick” in the system. THX certified subwoofers are
rated by the cubic volume of the room. Make certain you
remember to include all spaces that open to the theater in
that volume calculation. Depending on the size of your
space, you may require more than one subwoofer to get
the bass volume levels that you desire.
Power
Like many of today’s intelligent home electronics, the
Maestro should be plugged into an unswitched AC outlet
so that it always has power. This allows the RS-232 and
remote control features to work even when the Maestro is
in standby. We always recommend the use a high quality
surge protection device to keep all of your electronics safe
from the evils of public power systems.
Audio Connections
Most of the sources will have two audio connections to the
Maestro; the 2 channel analog audio and the multi-chan-
nel digital audio. When given the option, you should
connect both of these audio signals to the Maestro. This
will provide the digital audio signal necessary for high-
quality digital surround sound along with the analog
audio for tape recording and the second zone audio
output.
Don’t worry if your satellite receiver has a coaxial digital
output and the Maestro SAT input is optical. Refer to the
advanced configuration section on page 3-9 of this manual
for more information regarding assigning a digital input to
the optical or coaxial connection.
Multi-Channel Analog Audio
Newer audiophile surround recording formats such as
SACD and DVD-A decode the multi-channel signals directly
within the player. The Maestro features an 8 channel direct
analog input for these sources. These inputs bypass the
digital circuitry in the Maestro and route directly to the
Main Amplifier outputs via its own volume control circuit.
This ensures the highest possible audio quality for this
input.
