About the A40 MixAmp™
Congratulations on your purchase of the ASTRO Gaming A40 MixAmp™!
Whether you are a professional video gamer, a casual player, or a hardcore
hobbyist, we’d like to welcome you into the ASTRO family of performance
gaming accessories.
The A40 MixAmp™ is the result of countless hours of research and development by the foremost experts in the audio industry, extremely talented
industrial designers, and an elite cadre of professional video gamers.
Despite its small size, the A40 MixAmp™ contains a complex electronics
package, and we’d like to ask that you to continue to read this instruction
guide. Please also keep it for later reference: it contains important warranty
information, and a handy troubleshooting guide.
For all of you Han Solos out there, the Quick Start Guide should be enough
to get you started, but come back later for deeper advice and better tips
than the Quick Start Guide can give you.
The A40 MixAmp™ is your own personal audio mixer and headphone amplier. We developed it specically for enhancing the audio and communications experience of video gaming. With Dolby® Pro Logic II and Dolby®
Digital decoding feeding into Dolby® Headphone, the A40 MixAmp™ is a
home theater in the palm of your hand.
Whether you’re gaming at home alone, socially on a LAN, on a console or a
PC, the A40 MixAmp™ has something to offer.
For Xbox and Xbox 360 users at home, the A40 MixAmp™ enables you to
combine voice communication and game sound in one headset - ideal for
discrete “midnight gaming” sessions. You can also add your own soundtrack
to any game as you play. Simply connect your music player to the mp3 input
and you’re good to go.
For PC gamers, the A40 MixAmp™ enables you to ofoad surround sound
decoding and voice communication duties. Don’t <Alt - Tab> yourself to an
untimely death trying to manage a software-based music player - just connect your mp3 player to the A40 and keep your gaming rig focused on the
task at hand.
In a LAN environment, your A40 MixAmp™ can be daisy-chained with any
number of other A40 MixAmps™ - creating a private, hands-free, full-duplex
voice communication channel - much higher-quality than VoIP systems, with
zero network lag.
ABOUT DOLBY® SURROUND TECHNOLOGY
Unlike many other generic “5.1” audio products on the market today, the
A40 MixAmp™ is a genuine Dolby® product - containing Dolby® Pro Logic
II, Dolby® Digital, and Dolby® Headphone surround technologies. Dolby®
is the only surround format used to encode current games, and authentic
Dolby® products should be your only choice when you want a superior
audio experience.
While you might be aware of what Dolby® Pro Logic II and Dolby® Digital do in a multi-channel environment, you may not be aware that Dolby®
Headphone offers the same benets to users of two-channel headphones.
Using advanced patented audio processing technology, Dolby® Headphone
simulates a multi-channel speaker array using any standard pair of stereo
headphones.
Dolby®, Pro Logic and the double-D symbol are registered trademarks of
Dolby® Laboratories, Inc.

While the ASTRO Gaming A40 MixAmp™ contains a complex electronic
package, controlling it is quite simple.
The MASTER VOLUME knob raises and lowers volume of all incoming audio
feeds together. It will not raise or lower the volume of your outgoing voice
communication. (The distance between your microphone and your mouth is
the best way to adjust this).
The BALANCE control enables you to dial in the perfect mix of game-tovoice communication.
Important: It is possible to bring either the GAME or the VOICE volume
down to 0% volume, at either end of the BALANCE control dial spectrum.
Most people nd that the ideal mix is somewhere between 11 and one
o’clock.
The DOLBY® on/off button turns on Dolby® Digital (when connected with
a digital cable), or Dolby® Pro Logic II (when connected with an analog
cable). Dolby® is active when the surrounding RED light is illuminated.
When the DOLBY® button is not illuminated, the A40 MixAmp™ is operating in 2-Channel stereo mode, and no Dolby® processing is applied to the
incoming audio signal.
The MASTER POWER button does exactly what you might expect, and is a
convenient way to mute the audio to your headset or headphones.
Important: When the headset is disconnected, the A40 will automatically
shut down. This feature is to prevent accidental power loss when you are
traveling with your A40. If you reconnect your headset within a short period
of time, your A40 will automatically return to the state you had it in before
it was disconnected. If you reconnect after this short time, you’ll need to
restart the A40 manually.
When your A40’s batteries are low, the RED ring around the MASTER
POWER button will ash ON and OFF intermittently. A SOLID RED button
indicates adequate power.
If you are using the optional A40 rechargeable battery pack, an AMBER ring
around the MASTER POWER button with ash ON and OFF when the bat-
tery is recharging (plugged into USB power). When the charge is complete,
a SOLID AMBER ring will illuminate.
You can check the power state of the A40 at any time, whether or not a
headset is connected. The MASTER POWER button will illuminate for a short
time, indicating how much charge the battery contains (FLASHING - low, or
SOLID - OK), and then the A40 will shut back down automatically.
