tournaments - but permanent hearing loss may occur if headphones or earbuds are used at a high volume for an
extended period of time. Reduce the volume or discontinue use of the Rx immediately if you experience any
discomfort, feel blood or bile oozing out of your eardrums, or hear ringing in your ears.
CONNECTING AND PAIRING THE MIXAMP 5.8 Tx AND Rx
Step 1 - Setup the Tx
The MixAmp 5.8 Tx is a powerful wireless transmitter capable of delivering Dolby®Surround Sound to multiple Rx
receiver units.
Remove the Tx unit from the packaging and place in an unobstructed location near your console or home theater system.
Remove the Power Supply and plug into your wall output and the input on the rear of the Tx labeled PWR.
Using the included TOSlink cable, plug either end into the jack on the rear of the Tx labeled OPT. IN.
For Playstation 3, PC and Mac users who want voice communications, plug the ASTRO USB Voice Chat cable (sold
separately) 3.5mm jack into the input labeled AUX. IN.
Turn the Tx on by pushing the Power button.
Step 2 – Setup the Rx
The MixAmp 5.8 Rx is compact wireless receiver, mixer and amplifier unit. Multiple Rx units can be paired to a single Tx.
Remove the Rx unit and AAA batteries from the packaging. A rechargeable battery pack is also available (sold
separately).
Remove the rear battery door of the Rx by pushing the button on the top rear down and moving the door up and out.
Note, you cannot remove the battery door with the belt clip attached
Insert the AAA batteries. If you are using the optional rechargeable battery pack, grip the battery compartment on the top
sides and gently pull it out. The connections for the rechargeable battery are underneath.
Replace the battery door by aligning the tabs at the bottom first, then snapping the top into place.
If you so desire, connect the pocket clip around the battery door on the rear of the Rx. It will only go on in one direction
so if it does not seem to fit just flip it around the other way.
Plug your ASTRO A30 or A40 (or other third party) headset 3.5mm connector into the jack on the bottom of the Rx
labeled with a small headset icon.
If you want to charge up your rechargeable batteries, plug the included USB charge cable into the bottom of the Rx and
the other end into the rear of the Tx. The Rx power light will glow amber when the battery is charging, returning to its‟
regular red state when charging is complete.
For Xbox Live chat, plug either end of the included controller cable into the input on the bottom of the Rx labeled with a
small controller icon.
Step 3 – Pairing the Rx and Tx
Your Rx and Tx units should be paired right out of the box. If no audio is detected, please follow the steps below to
ensure your audio system is paired.
With your Tx turned on, press and hold the Tx power button until it glows white and begins to blink.
Turn your Rx on. Press and hold the Rx power button until it glows white and begins to blink. Make sure you have a
headset plugged in to the Rx headset input or it will automatically power off to save battery life.
Momentarily, both the Tx and Rx lights will go solid white to indicate successful pairing and then return to their regular red
glow to indicate normal operation. If you are charging an Rx battery, the power button will return to glowing amber.
