A40 MixAmp™ Controls
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-to-
voice 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 operat-
ing 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.
