Product Highlights
Product Highlights
Built For The Long Haul – “Bulletproof” is the phrase that
best describes The Pantages G3. Everything about this amplifier says that it is in there for the long haul. This amplifier
has been designed with durability in mind. The cool running
Class H design minimizes component damaging heat while the
Lightdrive system protects your speakers from harmful harAudioControl Class H Amplifier
Energy Savings monics caused by clipping.
AudioControl amplifiers have an innovative power
supply that acts as a transmission, shifting up and
down. This keeps them running cool and energy
efficient.
Typical Amplifier Design
Excess
Heat
A typical amplifier wastes a lot of energy as heat
Class H Design – Most amplifiers have one speed, all on.
That means that during most of music up to 90% of the amps
power is just going up in heat. The Class H design takes care
of this problem by automatically and intelligently adjusting the
power supply to fit the power demands of the moment. The
result is much cooler operation without the need for bulky
heatsinks or fans.
Lightdrive Protection System – The Lightdrive protection
circuitry defends this amplifier and speakers against clipping,
distortion, damage, and annoying teenage beach party movies.
Even if the movie festival lasts all weekend. Each channel is
independently protected so a problem in one channel will not
affect the rest of the system.
High Definition BiMOS Output Design – Home Theatre
audio systems place terrific demands on power amplifiers. The
high current drive capabilities of our BiMOS outputs cleanly
delivers a minimum of 230 watts while maintaining a cool
head.
Unparalleled energy efficiency ­– Whether from the point of
view of saving electricity or from the viewpoint of less heat in
the rack, this amplifier has no equal. It is VERY energy efficient during operation.
Made in the Northwest Rainforest The AudioControl
Pantages G3 begin their existence at our factory in Mountlake
Terrace, Washington, a few miles north of Seattle. Here, we
also build precision test instruments, equalizers and analyzers and a totally awesome line of car stereo components.
AudioControl started in 1977 and has won so many audio
industry awards for design and engineering excellence that our
reception room wall is starting to sag. But enough about us.
Let’s start getting the most from the home theatre system so
we can get the popcorn ready! (remember though, these amps
runs really cool, so you’ll have to use the microwave to melt
your butter)

Front Panel
1. Power Standby Button - The infamous “Off” light. This button manually toggles
the main power on The Pantages G3 between normal operation and stand-by. This button will over-ride the rear panel remote 12 volt trigger, but normal operation will resume
when the trigger input is cycled.
2. Display Button - Shuts off the bouncing blue channel level indicators for those
easily distracted movie goers.
3. Channel Status LED’s - These cool blue LED’s show when the corresponding
channel is active and operating normally. They turn red if something has caused that
channel to go into protection.
4. Channel Level Indicators - Each channel has a ladder of LEDs to bounce along
with the music and show the relative audio signal levels. If you find them too distracting, the DISPLAY button turns these lights off.
5. Protection Indicator - This indicator turns red when one of the internal protection
circuits (thermal, short-circuit, offset) have come into use. All the protection circuits
automatically reset themselves when the problem causing the fault has been fixed.
6. Rack Mounting (not shown, optional) - If your installations is in a 19” world; an
optional rack mounting kit is available for The Pantages G3. These rugged steel brackets
securely embrace the sides of this amplifier to mount it in a 5.25” (3U) rack space.

Rear Panel
1. Remote Power Control - This three pin connector allows you to remotely turn
on The Pantages G3 via an automation system. You can either use a contact closure
between the Trigger In and the +12V output or an external 12 volt trigger between the
Trigger In and Ground terminals. The +12 volt output is not designed to power other
pieces of equipment; it is a current-limited output for controlling The Pantages G3 only.
2. Inputs - The Pantages G3 features both unbalanced RCA and balanced XLR inputs
to connect your preamplifier’s outputs. Any standard line level audio signal should be
connected to these inputs.
3. Speaker Outputs - These high-current terminal blocks are designed to make any
custom installer sit up and smile. Their solid construction and gold-plated connection
surfaces will accept large gauge audiophile speaker wiring, pin, fork and of course, standard 0.75” spaced banana plugs.
4. AC Power Fuse - The Pantages G3 is designed with several layers of protection
circuitry. This power fuse is here just in case something really awful goes wrong.
5. Master Power Switch - This switch shuts off the main AC power. Normally the
only time you need to turn the master power switch off is if the system is going to be
shut down for an extended period of time.
6. Power Inlet - The Pantages G3 draws an average of 700 watts with typical source
material. Make certain that it is plugged directly into the wall outlet, or surge protector power strip with sufficient power rating. Since The Pantages G3 has remote power
switching, you can plug the unit into an outlet that is always active.

Installation
Installation
What follows is a step-by-step guide to integrating this new amplifier into
a home theater system. If it seems overly detailed, please forgive us. We
would rather tell you too much than too little.
Placement
The AudioControl Pantages G3 is a very cool running amplifier, but it does
need some breathing room to operate properly. Make certain that the air
vents on the top and bottom of the amplifier are not blocked and have at
least ½” of air space. Also make certain that heat sensitive components
such as cable boxes or DVD players are not directly on top of The Pantages G3. Just as a reminder, you should also avoid putting any leaky potted
plants on the audio equipment stack.
Power
Don’t plug it into a switched outlet on your system unless you are certain
that it can handle the power rating. Also, please don’t cut off the ground
pin on the power connector. It is an important safety feature. If you need
to plug it into a two prong outlet, use a ground adapter (and connect the
ground on it).
Remote Power Control
The Pantages G3 has three levels of power control:
1) Main AC Power switch- This is the master control and must be turned
ON for the amplifier to function. Normally the only time that you would
need to turn the AC power switch off is when the system is going to be
unused for an extended period.
2) Remote Power Control- This removable 3-pin remote connector on
the rear panel allows simple interfacing with external control systems. It accepts either a contact closure or external +12 volts DC. (see diagram)
3) The third level of power control is the front
panel STANDBY button. When there is AC
power and the rear panel AC MAIN switch is
on, this button lights blue. When the amplifier
is turned on, either by pressing the STANDBY
button or with the remote power trigger input,
the blue led on this button turns off.

Hooking up Your System
Audio hook-up
If you’re an installation veteran, this may seem repetitive, but some things
can never be repeated too many times.
1) Turn off ALL components before making any connections.
2) When making connections, designate RED RCA plugs as RIGHT and
WHITE, BLACK, or GREY plugs as LEFT. In fact, this is a good idea for
ALL signal connections made in your audio system. The key is consistency.
Stick with the same color-coding and you’ll reduce possible problems.
3) Whenever possible, keep power cords away from signal cables to prevent
induced hum. This is especially important if you bundle the cables to keep
the installation neat looking.
4) Use quality interconnect cables. We’re not going to get into the debate
about whether $100/meter cables improve the sound, but we know from
experience that really, REALLY cheap cables can cause a multitude of
problems. They tend to break inside or corrode, causing a loss of signal or
hum. They also have poor shielding.
5) If you need to run the audio cables more than 20 feet you should consider using the balanced XLR inputs. This will provide better noise rejection
against nasty things like hum, spikes, local talk radio, etc. If your surround
processor doesn’t have balanced outputs, the AudioControl BLD-10 balanced line driver is an excellent way to convert unbalanced RCA audio
outputs to a balanced signal (see the appendix for details).
Speaker Hook-up
The same rule applies to the speaker wires as the audio connections. Establish a standard connection color code and stick with it. One conductor
of the speaker wire is normally marked by a different color (silver versus
copper) or there is a ribbing on one side. Typically this marked conductor is
used for the positive (+) speaker leads. Of course the really good wire has
Positive and Negative printed right onto the wire jacket.
Your choice of speaker wire gauge and the length
of the runs also affects the speaker impedance
load presented to the amplifiers. As you can see
in this table, even fairly short speaker runs can
have a very significant resistance if you use a
smaller wire gauge. The downside of this resistance in the wire is that you waste the total
power available to the speakers.
12
Pantages G3
™
www.audiocontrol.com
®
Hooking up Your System
All that resistance in the speaker wire will turn some of your amp power
into heat.
A common practice among system designers is the 5% rule. This rule states
that the wire resistance should not exceed 5% of the speakers minimum
resistance. This keeps the volume level change due to line losses to less
than 0.5dB.
As an example, on an 8 ohm speaker the wire resistance should be less than
0.4 ohms (5% x 8 = 0.4). You will need to use at least 14 ga wire on a 100’
run to obtain this resistance.

Can I bridge the outputs of my AudioControl theater amplifier?
The answer is “No”. This amplifier is designed to drive discrete speaker
channels therefore it is not recommend that you attempt to bridge the
outputs in an attempt to produce more power
Congratulations! You’re done with the hook up. Now pop up that corn and
you’re ready to enjoy the movies.

Brazen Plug
A Brazen Plug For Other AudioControl Products
AudioControl started out making audio components in 1977. Our heritage
and design experience grew from a background in professional audio, so we
were never quite satisfied with what was available for the consumer audio
market. Since that time, we have continued to expand our product offerings to become a key part of home theater systems. We supply the audio
components that can make a greater improvement in the sound of your
system than almost any other addition or upgrade. More bass, better bass,
less harshness and the ability to hear music the way you want it.
AudioControl also manufacturers a theater pre-amp processor, the Maestro M3, which is a perfect companion for our home theater amplifiers.
This very stylish processor provides decoding for all hi-definition surround
formats like Dolby Tru HD and DTS theater master. In addition it is
equipped with over 120 video and audio inputs and outputs that work with
all of today’s sophisticated source units, including those with HDMI connections. Okay, enough commercials.
Once again, we thank you for choosing an AudioControl components in
this system and hope you enjoy a lifetime of performance and reliability.

Appendix & If You Need Service
Appendix - Going the Distance and Getting Balanced
When you need to run a line level audio signal more than 20 feet; balanced
is the best way to go. It provides greater noise and ground loop rejection
than normal RCA connections. What do you do if your preamp doesn’t
have XLR outputs? No problem, just whip out a couple of the handiest
items to have around: The AudioControl BLD-10 balanced line driver.
These little boxes provide a clean and accurate means of converting unbalanced to balanced.
What to do if you need service
First, contact AudioControl, either by phone 425/775-8461 or FAX
425/778-3166 or by e-mail at sound.better@audiocontrol.com. 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 Pantages G3. (You’d be surprised how many people forget this.)
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.
And now a word from the legal department...

Warranty
Legalese Section
This is the only warranty
given by AudioControl. This
warranty gives you specific legal
rights, and you may also have
rights that vary from state to
state. Promises of how well your
Pantages G3 will work are not
implied by this warranty. Other
than what we’ve said we’ll do in
this warranty, we have no obligation, express or implied. We
make no warranty of merchantability or fitness for any particular purpose. Also neither we
nor anyone else who has been
involved in the development
or manufacture of the unit will
have any liability of any incidental, consequential, special or
punitive damages, including but
not limited to any lost profits or
damage to other parts of your
system by hooking up to the unit
(whether the claim is one for
breach of warranty, negligence
of other tort, or any other kind
of claim). Some states do not allow limitations of consequential
damages.
Failure to register a proper
warranty information negates
any service claims.
The warranty included with
the unit shall supersede this
plain-text version if there is any
inconsistency between the two.
www.audiocontrol.com
The WARRANTY
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 the 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 home theater system
amplifier before logging onto the our web site at www.audiocontrol.com
and register your purchases.
“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
your amplifier for five (5) years from the date your customer bought it,
and we will fix or replace it, at our option, during that time. Here are the
conditional conditions:
1. You need to register your purchase with us by going to the
AudioControl web site (www.audiocontrol.com), click on the “Home
Theater” tab and then go to the warranty registration department and
follow the directions.
2. Your customer must keep their 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. Your AudioControl amplifier 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 Pantages
G3. If anyone other than (A) or (B) messes with your amplifier, that voids
your warranty.
5. The warranty is also void if the serial number is altered or removed,
or if your amplifier 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 it 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.
