 Using A40 MixAmps™ together in LAN or in a 
 tournament (Console)
Using the built-in voice communication function of the A40 MixAmp™ will 
instantly enable a high quality, ‘lag-free’ voice channel. You’ll nd the voice 
quality between Daisy-Chained A40s is MUCH higher than Xbox Live, for 
example, so always use the A40’s voice communication feature when you 
game together in the same place with friends. 
To enable the voice communication channel, simply use the included daisy-
chain connector (or one of the included 3.5mm-to-3.5mm cables for longer 
runs) to connect two or more A40 MixAmps™ to each other. Connect the 
A40’s by using the front 3.5mm connectors at the bottom of the MixAmp™ 
(where the Daisy-chain connector usually resides). Once both units are 
powered on, you can now freely speak to your teammates in this new voice 
channel. Adjust the BALANCE control to dial in the ideal amount of Game/
Voice ratio.
Important: You can continue to use Xbox Live communication at the same 
time you use a local (daisy-chained) voice channel, as long as your A40’s 
CONTROLLER port is connected to your Xbox controller with the included 
2.5mm-to-2.5mm cable.
You can mute outgoing Xbox Live communication at any time by discon-
necting the 2.5mm cable - the Daisy-chain voice communication channel be-
tween you and your teammates will remain unaffected. While playing games 
with proximity voice detection (like Halo, for example), your opponents will 
NOT be able to hear you and your teammates speaking. That is, until you 
plug the cable back in and smack talk in the game lobby.

Step 2 - Connect to Xbox Live
If you are using a headset with a microphone, and an Xbox or Xbox 360, 
you can easily mix in voice communication from Xbox Live. For Xbox 360 
users, connect the 2.5mm-to-2.5mm cable to the back of the 360 controller. 
Then connect the free end of the 2.5mm cable to the CONTROLLER port on 
the front of the A40 MixAmp™. If you are using the A40 MixAmp™ with the 
original Xbox, simply use the original Microsoft Volume Pod along with the 
supplied ASTRO Gaming 2.5mm cable.
Important: If you are using a non-ASTRO headset, be sure to use the sup-
plied Dual Jack-to-3.5mm 4-pole Adapter to integrate the microphone func-
tion of your headset with the A40 MixAmp™. Otherwise, your headset will 
function normally, but without the microphone feature.
Step 3 - Connect an External Audio Source (optional)
With the A40 MixAmp™, you can mix an additional external audio source 
(like an mp3 player) into your games. Use one of the supplied 3.5mm-to-
3.5mm cables to go from the headphone output of your player to the MP3 
input on the back of the A40 MixAmp™. This enables you to instantly inject 
your own soundtrack - and keeps your mp3 player within arm’s reach for 
easy adjustment. 
Important: The MP3 input is NOT connected to the balance function on the 
A40 MixAmp™. You’ll need to use the volume control on the player itself in 
order to nd the right balance of music to game sound. Also, if you are con-
nected to other A40 MixAmps™ in Daisy-chain conguration, don’t worry 
about bothering your teammates with your music - they can’t hear it.
