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 com­ponent that does as much as the Maestro does deserves all the expla­nation 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.

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 time­honored 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 connec­tions.

• Wherever possible, keep power cords away from signal
cables (i.e., inputs from disk players, VCRs, etc.) to pre­vent induced hum. Bundle all power cords down one
side of your equipment cabinet and all the signal cables
down the other.

Installation

• Use high quality interconnect cables. We’re not going to
get into the debate about whether $100 per meter inter­connects 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 line­of-sight between the location where the remote controller
sits and the Maestro front panel.

Maestro

Section 2-3

Installation

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 2-4

Maestro

tm

Phone [phone] • Fax [phone]

®

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-chan­nel 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 high­quality digital surround sound along with the analog
audio for tape recording and the second zone audio
output.

Installation

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.

480p, HDTV), so please don’t confuse them.

Because of the higher bandwidths involved with video
signals, the quality of the interconnect cables you choose
is more critical than the audio cables. Video connections
should always be made with cables specifically designed
for video. Don’t be tempted to grab some extra audio RCA
cables laying around. Without the proper 75 ohm coaxial
cabling, your picture quality will suffer from smear, ghost­ing or noise. It is always a good idea to make certain that
the video and audio signal cables are routed away from
any power wiring.

Video Conversion

High quality conversion between the various video signal
connection formats is a tricky thing and best left to dedi­cated video processors. This is why the Maestro doesn’t do
this conversion. If a source input is S-Video, the Maestro
will output S-Video to the monitor or projector. You will
usually need to run all three (Composite, S-video, and
Component) main video outputs of the Maestro to your
video scaler or monitor.

Input Configuration

The component video inputs are fully assignable to the
sources. This allows you to configure the Maestro to look
for the video input from a particular source unit on one of
the three component video inputs. Refer to the Configura­tion section of this manual on page 3-8 for more informa­tion regarding this feature.

Installation

IR Remote Control Connections

Since the Maestro is often hidden away in some dark
closet or equipment rack, we have provided connections
for external IR remote control receivers and emitters. This
allows you to place the infrared receiver where it can “see”
the signal from the remote control. The Zone 2 IR input
controls the second zone functions of the Maestro and also
repeats commands to the source units through the emitter
output.

The IR receiver input connections are wired with a 3
conductor 3.5mm jack. The signals are compatible with
third-party receivers such as a Xantech No. 291-10.
AudioControl does not supply the IR receivers or emitters
to use with the Maestro.

Sleeve Current Limited +12 VDC (30 mA max.)

1/8” Mini Jack wiring

12V Trigger Connections

There are three mini-jack 12 volt trigger outputs on the
rear panel of the Maestro. These are used to remotely
control such things as the power amplifier turn-on, projec­tor power, screens or curtains. The System Trigger Jack has
two separate outputs. The jack is a three conductor; Tip,
Ring, Sleeve, connection.

Tip Main Zone On
Ring Second Zone On

The other two trigger outputs carry one signal each. The
Main Trigger connection has 12 volts DC when the Maestro
is turned on. The Video Trigger jack goes to 12 volts when
one of the video sources is selected.

Tip +12 VDC
Sleeve Ground

The Main Trigger would generally be used to control the
power to the amplifiers and source units. The Video Trigger
would be used to control the projector or video screen.

Second Zone Connections

Plug for other AudioControl products: The
Active-Balanced Series products from
AudioControl enables sending high-quality
audio and video signals over standard Category
5 or better twisted pair wiring. Great for getting
the second zone outputs of the Maestro across
the house to your bedroom.

Installation

The Zone 2 outputs on the Maestro enable sending an
independent audio and video signal to a second room,
such as a bedroom. There is a 2 channel stereo analog
audio output and a composite video output.

There is also an IR sensor input for the second zone. This
enables you to remotely control the Maestro and also
repeats the IR to your source units through the IR Output
jack on the Maestro. Any IR signal received through the
Maestro’s front panel IR sensor or through an IR sensor
connected to the IR inputs is repeated to the IR Output for
controlling the source components in your system.

Since the Zone 2 outputs of the Maestro are 2 channel
analog audio and composite video, you must have these
signals connected from your source units to make them
available. The Maestro does not convert a digital audio
signal into analog for zone 2.

have a speaker connected to an output (i.e. No Subwoofer

3. Delay Settings

The Speaker Delay settings help ensure that the sound
from each speaker arrives at the listening seat at the same
time. This provides a much more believable immersive
sound environment. Proper delay settings should be done
by a trained professional with audio test equipment such
as the AudioControl Iasys HT to measure the actual sound
delay timings. You can get a rough delay setting using an
assistant and a tape measure. Measure the distance from
the center of a speaker to the seated ear position of the
main listening seat. Write each of these distances down
and enter them into the Maestro.

speakers. If this happens, set the Left
Speaker Level Setting to 0dB and measure the

other speaker channels and match their SPL
readings to that of the Left speaker.

It is critical to properly match the levels from each speaker
to achieve a correct sound stage. The realism is totally lost
if the footprints of a person walking across the screen
change in volume as they move from left to center to right.
We strongly recommend using a test analyzer such as our
IasysHT or a sound level meter for this calibration. The
levels are nearly impossible to judge by ear alone.

With the internal test noise generator of the Maestro,
adjust each speaker for a sound pressure level (SPL) of 75
dB using a “slow” response time on the SPL meter placed at
the main listening position at ear height. Use the s Mode
and t Effect buttons on the Maestro to select a speaker
channel, then adjust the volume of that speaker with the

Using the Maestro

Now that you’ve gotten everything connected together and
configured properly, it’s time to sit back and enjoy the
fruits of your labor. Since the Maestro gives you two inde­pendent “zones” to view and listen to your system (the
Main home theater zone and the remote Zone 2) we’ll
cover them separately. The primary different between the
two zones is that there is multi-channel surround sound
for the Main zone and 2 channel stereo in the second
zone.

Main Zone

All operation of the Maestro can be done with either the
front panel display or the On-Screen Display (OSD) on the
video display. The OSD is simpler to use since the larger
display allows all the menu options to be listed at once.

Using the Maestro

Turning the Maestro On

There is actually two levels of turning the Maestro on.
Firstly, the main front panel
This turns on the AC power to the Maestro. In most sys­tems this power switch will ALWAYS be left on so the
theater automation system can control the Maestro. When
the Maestro receives a power off command from the IR or
RS-232 inputs it goes into a sleep
Maestro is a very light sleeper and will wake back into
normal operation by pressing any source input button or
sending a power on command from the IR or RS-232
inputs.Choosing your Input

Using the Main Menus

The Main Menus enable the user to make temporary
changes in the operation of the Maestro. These settings
clear away when you turn the Maestro to Off or Standby.

Integration with Automation

Introduction

Part of the joy of a great home theater is that you don’t
have a tray of remote controls staring at you whenever you
want to watch a movie. Hidden away behind the scenes is
a workhorse that takes care of the mundane tasks of turn­ing on all the components, lowering the curtains, dim­ming the lights, popping the corn, etc. This faithful ser­vant can take the form of a simple learning remote control
or a system as capable as a whole house automation sys­tem with touchscreens. There is a wide variety of theater
controllers available.

There are two means of remotely controlling the Maestro:
With Infrared (IR) Remote control and with the RS-232
Serial Port. Both of these methods feature a very extensive
library of commands. It is really up to the system designers
choice of user interface as to which of these methods will
be used. It is possible to use both of these in the same
installation depending on your needs.

Integration with Automation

Infrared Control versus RS-232

Infrared remote control systems are typically less expensive
than RS-232 controllers. Their main limitation is that
Infrared is strictly line-of-sight. That means that there has
to be an unobstructed view between the controller sending
the infrared commands and the IR sensor or front panel of
the Maestro. When you try to send long groups of com­mands (macros) such as: Turn on the TV, Turn on the
Maestro, Turn on the DVD, Select the DVD Input on the
Maestro, Play the DVD; everything can easily get out of
sync if you sit down the IR controller or somebody walks
in front of you before all the Infrared commands have been
sent. Infrared is also typically a one-way communication.
There is no way for the IR remote to know if the command
was received correctly.

RS-232 Serial control is a hard-wired connection. There is
usually a wire connecting the user interface (keypad or
touchscreen) to the controller system. Then another wire
connecting the controller system to the Maestro. RS-232 is
also a two-way communications scheme. This allows the

Phone [phone] • Fax [phone]

Maestro

®

tm

Section 5-1

Integration with Automation

RS-232 Serial Control

controller system to send very long, complex strings of
commands and get an answer back to know that all those
commands were executed properly.

You must set the external RS-232 control system serial port
to match the data speed and format that the Maestro is
expecting. If these settings are not correct, the Maestro will
not respond to the commands.

Set your communication parameters as follows:

Baud Rate:38,400
Data Bits: 8
Parity: None
Stops Bits:1
Flow Control: None

The cable wiring to connect the Maestro to your control
system will depend on the RS-232 output connection on
the controller. Make certain that you wire the Transmit
Data output on the serial controller to the Receive Data on
the Maestro and vice versa on the Receive Data line on the
controller system. Connect the signal grounds on the
control system and the Maestro together. The RS-232
connection on the Maestro is a DB-9 Male wired as follows:

Section 5-2

Pin 2 Receive Data (RXD)
Pin 3 Transmit Date (TXD)
Pin 5 Ground

To connect the Maestro to a standard PC serial comm port;
wire the cable in a ‘null modem’ arrangement.

Protocol Structure

The RS-232 serial control protocol structure of the Maestro
is a string of ASCII characters terminated with an ASCII
Line Feed (0x0A hexadecimal). Multiple commands can be
linked together on one line separated by a semicolon, but
the total command string cannot contain more than 64
characters (including spaces and the Line Feed terminator).

Integration with Automation

Control Commands

Install Note:Install Note:

Install Note: Refer to Appendix “C”

Install Note:Install Note:

for the complete listing of commands.

In the following examples
Feed. How you actually enter that character into your serial
control system varies by manufacturer. Check with their
programming information about direct ASCII character
entry.

Example:

To turn on the Maestro for Zone 1:

Z1PWR1

To turn on the Maestro and select the DVD source:

Z1PWR1;Z1AUD5

Command processing begins when the first semicolon
separator line feed terminator is received. When a com­mand is executed properly, the Maestro echoes the
command back. If there is an error in the command, the
Maestro will return an error message of “FAIL”.

There are two types of serial control commands: Settings
and Queries. The Setting commands instruct the Maestro
to execute a function. The Query commands allow the
external control system to ask the Maestro the current
state of a function (i.e. Power, Mute, Input Source). To use
the query function, precede the command with a question
mark. Only a subset of all the serial commands have a
query function.

Surround Modes

The Maestro theater processor contains two powerful
digital signal processing (DSP) ICs. These components
enable the Maestro to decode multiple digital and analog
multi-channel surround sound formats. Since the Maestro
is fully programmable, new surround decoding formats
can be incorporated as they become popular.

Selecting Surround Modes

There are three groups of surround processing modes in
the Maestro. These are selected using the

mands in the external control protocols. The
provides supplemental processing to improve the overall
surround effect. The
processing effects for two channel sources only. The
button manually selects the surround decoding mode
when the source media does not automatically configure
the Maestro.

Modes for Digital Sources

Digital surround recordings have details of their decoding
requirements encoded into the media. The Maestro auto­matically detects this information and switches to the
appropriate surround mode.

Modes for Analog Sources

Two channel analog audio sources do not contain informa­tion about their surround encoding method. This means
that you will have to choose the surround mode that you
find sounds best.

Mode Memory

The Maestro automatically remembers the last surround
mode used for each source input. Since most digital sur­round recordings have control information encoded into
them; the Maestro will switch to the decoding method
requested by the source material.

THX processing offers additional performance benefits in
addition to the standard surround decoding modes. THX is
an exclusive set of technologies and standards established

Surround Modes

by Lucasfilm Ltd. THX grew from their desire to make your experience
of home theater as close as possible to what the movie director in­tended.

THX engineers developed patented technologies to accurately translate
the sound from the movie theater environment into the home, correct
the tonal and spatial errors that would otherwise occur.

About THX Cinema Processing

Lucasfilm defined a series of technical performance standards that
equipment must meet or exceed before it is allowed to wear the THX
certification logo. Several levels of performance standards are defined,
the most demanding standards are set for THX Ultra 2, which is your
guarantee that the Home Theater products you purchase will give you
superior performance for years to come.

A list of available DVD titles encoded with Dolby Digital Surround EX
technology can be found at www.thx.com or www.dolby.com.

Re-Equalization™

The tonal balance of film soundtracks can be excessively bright and
harsh when played back over home audio equipment because these
soundtracks were mixed to be played back in a large movie theater. Re­Equalization restores the correct tonal balance for watching a movie in
the smaller home environment.

Timbre Matching™

The human ear changes our perception of sound depending on the
direction from which the sound is coming. In a commercial movie
theater, there is an array of surround speakers so the sound informa­tion is coming from all around you. In a home theater there are usually
only two speakers located to either side of you. the Timbre Matching
feature filters the information going to the surround channels so that
they more closely match the sounds coming from the front speakers.
This ensures seamless panning between the front and rear surround
speakers.

Adaptive Decorrelation™

The large number of surround speakers in a commercial movie theater
provides an enveloping sound. Because there are fewer surround
speakers and you are usually sitting much closer to them in a home
theater, the surround sound image tends to collapse towards the
speaker closest to you. Adaptive decorrelation slightly changes the time

Section 6-2

Maestro

Surround Modes

and phase relationship between the surround channels. This expands
the listening position and creates a more spacious surround sound
stage like a larger movie theater.

Advanced Speaker Array™

The Advanced Speaker Array (ASA) is a proprietary THX technology that
processes the sound going to the side and rear surround speakers. This
provides a more optimal surround sound experience. ASA is only
available in the THX Ultra2 Cinema and Music modes.

THX Cinema

THX cinema mode provides the additional processing required for the
optimal presentation of movies over the standard playback surround
modes.

In Surround reproduction, this mode provides Re-Equalization, Timbre
Matching and Adaptive Decorrelation as necessary to all channels.

In 2-Channel, this mode provides Re-Equalization of the Left and Right
channels.

In Mono, this mode provides Re-Equalization of the mono signal.

THX Ultra 2 Cinema

THX Ultra 2 Cinema mode plays 5.1 surround movies using all 7.1
channels, giving you the best possible movie experience. In this mode,
ASA Processing blends the side and rear surround speakers to provide
the optimal mix of ambient and directional surround sounds.

DTS-ES (Matrix and 6.1 Discrete) and Dolby Digital Surround EX en­coded soundtracks will be automatically detected in THX Ultra2 Cin­ema if the appropriate flag has been encoded into the material.

Some Dolby Digital Surround EX soundtracks are missing the digital
flag the enables automatic switching. If you know that a movie you are
watching is encoded in Surround EX, you can manually select the THX
Surround EX surround mode with the

THXTHX

THX button.

THXTHX

THX Surround EX and Surround ES

THX Surround EX – Dolby Digital Surround EX is a joint development
of Dolby Labs and the THX division of Lucasfilms Ltd.

In a movie theater, soundtracks that are encoded with Surround EX
technology are able to reproduce an extra channel which has been
added during the mixing of the program. This channel, called Sur­round Back, places sounds behind the listener in addition to the rest of

the standard surround channels. This additional channel provides the
opportunity for more detailed imaging behind the listener and brings
more depth, spaciousness and sound localization than with standard

5.1 surround encoding.

THX Music

For playback of multi-channel music, the THX Music Mode can be used.
In this mode, the THX ASA processing is applied to the surround chan­nels to provide a wide, stable, rear soundstage.

The following modes are available for multi-channel digital sources.
Special modes such as DTS ES and DTS 6.1 Discrete are only available
from properly encoded source materials.

Dolby Digital 5.1

This is the most commonly used surround format for DVD, Digital
Satellite and Broadcast television. Dolby Digital 5.1 delivers surround
sound with five discrete full-range channels and a low frequency bass
effects (LFE) subwoofer channel.

DTS 5.1

The DTS 5.1 mix is less common that the Dolby Digital format, although
it is generally acknowledged to having superior sound quality. It has the
same five full range channels plus the subwoofer channel.

DTS-ES

DTS ES is a 5.1 channel format based on DTS 5.1. There is an additional
center rear channel that is matrix encoded into the rear surround
channels for playback.

DTS-ES 6.1 Discrete

This is a true discrete 6.1 channel sound format. Unlike DTS ES, this
format has a true sixth channel mixed into the soundtracks. The DTS

6.1 Discrete mode only operates on sources with DTS 6.1 encoding. A
list of available DVD titles with DTS ES and 6.1 Discrete can be found at
www.dtsonline.com

Multi-channel Audio Source Modes

There are two different music surround playback methods: Those that
use the internal digital decoding of the Maestro (Dolby Digital or DTS
encoded) and the newer multi-channel audiophile Super Audio CD
(SACD) and DVD-Audio formats that have the decoding built into the

Section 6-4

Maestro

tm

Phone [phone] • Fax [phone]

®

players. The SACD and DVD-A formats bypass all internal processing in
the Maestro and feed directly to the amplifiers through the volume
control. Since the digital processing in the Maestro is defeated, there
are no mode adjustments available. The Dolby Digital and DTS encoded
music disks are treated the same as surround encoded movies and
have the same options.

Two-channel Modes

The following surround modes are available with two channel audio
sources. These include Stereo Analog, Dolby Digital 2.0 and PCM 2­channel digital sources.

Dolby Pro Logic II

This provides better surround channel separation that the original
ProLogic format. There are two ProLogic II surround modes: Music and
Movie. Use the method that sounds best to you.

Surround Modes

Dolby Pro Logic Emulation

This mode should only be used on ProLogic encoded source materials.
ProLogic processing on pure stereo sources can sound muffled and is
not recommended.

DTS Neo:6 Cinema

A movie surround decoding mode designed to provide a movie theater
environment soundstage with natural steering to all available surround
channels.

DTS Neo:6 Music

Similar to the Cinema mode but with a tighter surround effect for
most musical material.

Stereo

The Maestro works like a standard audio preamplifier in this mode.
This mode plays back standard analog audio sources along with 2
channel digital sources such as Dolby Digital 2.0 from some DVD
players and PCM digital CDs.

Mono

The left and right channels are combined into a single mono mix. This
can benefit some older recordings and video tapes.

the front, side and rear speakers. It simulates a small night club venue.

Concert HallConcert Hall

Concert Hall – The Concert Hall effect generates the ambient informa-

Concert HallConcert Hall
tion of a medium sized performance hall. Reflections and medium
length reverberation information is sent to all channels.

SportsSports

Sports – The Sports Stadium effect is ideal for watching live sporting

SportsSports
events. The open ambience is actively created around you. The center
channel is used for the dialog commentary.

ChurchChurch

Church – The Church effect uses a reverberation algorithm that em-

ChurchChurch
phasizes the smooth, rich reverberant sound of a large space. As the
name suggests, it works well for simulating the long reverberation of a
cathedral or church.

Appendix B –

Using the Maestro with
the Diva Room Correction Processor

While the Maestro is a very power surround processor, some things are
best left to a specialist. The Diva 24 bit digital room correction proces­sor is the part of the AudioControl Home Theater System product line
up designed to take the theaters sound quality up to the next level. The
Diva includes Graphic and Parametric Equalization, Digital Delays with

0.01 mS resolution, Crossover filtering, and Compressor/Limiter Dy­namics control for 8 channels of audio. It also includes 20 user-config­ured preset memories and a powerful automation integration protocol
to make this part of any dream system.

The Diva is simple to connect into the Maestro home theater system.

The analog inputs and outputs enable the Diva
to connect between the preamplifier outputs
of the Maestro and the inputs of your power
amplifiers (preferably the Pantages and
Avalon).

For adjusting the Diva, we
highly recommend using the
AudioControl Industrial
IasysHT theater analyzer
with the HT-100 switcher.
The IasysHT enables ex­tremely precise one-twelfth
audio analysis for treating
room acoustic mode prob­lems. The IasysHT is also
very capable with speaker
delay measurements. It will
measure delay timings down
to 1/8” to ensure the best
sound imaging that you
have ever heard from a home
theater.

Appendix C –

RS-232 Serial Control Protocol Commands

You must set the external RS-232 control system serial port to match
the data speed and format that the Maestro is expecting. If these
settings are not correct, the Maestro will not respond to the com­mands.

Set your communication parameters as follows:

Baud Rate: 38,400
Data Bits: 8
Parity: None
Stops Bits: 1
Flow Control: None

The cable wiring to connect the Maestro to your control system will
depend on the RS-232 output connection on the controller. Make
certain that you wire the Transmit Data output on the serial controller
to the Receive Data on the Maestro and vice versa on the Receive Data
line on the controller system. Connect the signal grounds on the
control system and the Maestro together. The RS-232 connection on
the rear panel of the Maestro is a DB-9 Male wired as follows:

Appendicies

Pin 2 Receive Data (RXD)
Pin 3 Transmit Data (TXD)
Pin 5 Ground

To connect the Maestro to a standard PC serial comm port; wire the
cable in a ‘null modem’ arrangement.

Protocol Structure

The RS-232 serial control protocol structure of the Maestro is a string of
ASCII characters terminated with an ASCII Line Feed (0x0A hexadeci­mal). Multiple commands can be linked together on one line separated
by a semicolon, but the total command string cannot contain more
than 64 characters (including spaces and the Line Feed terminator).

In the following examples
you actually enter that character into your serial control system varies
by manufacturer. Check with their programming information about
direct ASCII character entry.

Factory Theater Calibration Service

An integral part of the AudioControl Home Theater system
is the acoustical calibration of the system. Especially in
systems where the power of the Diva room correction
processor is used. To help with this task, AudioControl
offers a Factory Theater Calibration Service. A factory­trained technician using the AudioControl Industrial
IasysHT theater analyzer and other tools of the trade, will
come to your theater and ensure that you are getting the
best sound possible from your system.

For more information about this service, contact your
AudioControl sales representative.

Appendix F –

Updating the Maestro

The Maestro is designed to allow flash memory reprogram­ming of the operating firmware and the surround decod­ing via the rear panel RS-232 port. This task should only be
done by a trained service technician. Refer to the Audio­Control Home Theater System Support CD for the software
update program and detailed programming instructions.

Warranty

Warranty & Service

and now a word from the legal department…and now a word from the legal department…

and now a word from the legal department…

and now a word from the legal department…and now a word from the legal department…
People are scared of warranties. Lots of fine print. Months of waiting

around. Well, fear no more. This warranty is designed to make you rave
about us to your friends. It’s a warranty that looks out for you and
helps you resist the temptation to have your friend, who’s “good with
electronics”, try to repair your AudioControl product. So go ahead, read
this warranty, then take a few days to enjoy your new Maestro home
theater system before sending in the warranty card and comments.

“Conditional” doesn’t mean anything ominous. The Federal Trade
Commission tells all manufacturers to use the term to indicate that
certain conditions have to be met before they’ll honor the warranty. If
you meet all of these conditions, we will warrant all materials and
workmanship on the Maestro for five (5) years from the date you
bought it, and we will fix or replace it, at our option, during that time.

Here are the conditional conditions:Here are the conditional conditions:

Here are the conditional conditions:

Here are the conditional conditions:Here are the conditional conditions:

1.You have to fill out the warranty card and send it to us within 15
days after purchasing the Maestro.

2.You must keep your sales receipt for proof of purchase showing when
and from whom the unit was bought. We’re not the only ones who
require this, so it’s a good habit to get into with any major purchase.

3.The Maestro must have originally been purchased from an autho­rized AudioControl dealer. You do not have to be the original owner,
but you do need a copy of the original sales receipt or invoice.

4.You cannot let anybody who isn’t: (A) the AudioControl factory; (B)
somebody authorized in writing by AudioControl to service the Mae­stro. If anyone other than (A) or (B) messes with the Maestro, that
voids your warranty.

5.The warranty is also void if the serial number is altered or removed,
or if the Maestro has been used improperly. Now that sounds like a big
loophole, but here is all we mean by it:

Unwarranted abuse is: (A) physical damage (don’t use the Maestro to
level your projection TV); (B) improper connections (120 volts into the
RCA jacks can fry the poor thing); (C) sadistic things. This is the best
product we know how to build, but if you strap it to the front bumper
of your Range Rover, something will break.

Assuming you conform to 1 through 5 (and it really isn’t all that hard
to do) we get the option of fixing your original unit or replacing it with
a new one.

Warranty & Service

Legalese Section

This is the only warranty given by AudioControl. This warranty gives you specific
legal rights that vary from state to state. Promises of how well the Maestro will
perform are not implied by this warranty. Other than what we have covered in this
warranty, we have no obligation, express or implied. Also, we will not be obligated
for direct or indirect consequential damage to your system caused by hooking up
the AudioControl Maestro.

Failure to send in a properly completed warranty card negates any service claims.
Unwarranted abuse is: (A) physical damage (don’t use the Maestro to level your

projection TV); (B) improper connections (120 volts into the RCA jacks can fry the
poor thing); (C) sadistic things. This is the best product we know how to build, but
if you strap it to the front bumper of your Range Rover, something will break.

Assuming you conform to 1 through 5 (and it really isn’t all that hard to do) we get
the option of fixing your original unit or replacing it with a new one.

What to do if you need service

Normally service will be handled by your AudioControl system profes­sional who installed the system. If you’re the take charge kind of
person who wants to do this themselves, contact AudioControl, either
by phone [phone] or email at [e-mail]. We’ll
verify if there is anything wrong that you can fix yourself, or arrange to
have it sent back to our factory for repair. Please include the following
items with the returning unit:

1.A copy of your proof of purchase (that sales receipt we’ve been harp­ing about). No originals please. We cannot guarantee returning them
to you.

2.A brief explanation of the trouble you are having with the Maestro.

3.A return street address. (No PO Boxes, please)

4.A daytime phone number in case our technician has a question
about the problem you are having.

You’re responsible for the freight charges to us, but we’ll pay the return
freight back. We match whatever shipping method you send it to us, so
if you return the unit overnight freight, we send it back overnight. We
recommend UPS for any shipments.
