About the A40 MixAmp™
The A40 MixAmp™ is your own personal audio mixer and headphone ampli-
er. We developed it specically for enhancing the audio and communica-
tions 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 con-
nect 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.
