Connecting The A40 To An Audio Source; Using With The A40 Mixamp - ASTRO A40 Instruction Manual

Connecting the A40 to an Audio Source

Attaching the Quick Disconnect to the A40 Headset
The A40 Headset includes two different cables. Each of the cables includes
an A40 QUICK DISCONNECT jack, and the other side contains each of the
following: a dual-jack connector (mic and audio) for connecting to a PC, and
a single 3.5mm 4-pole connector for connecting to the A40 MixAmp or any
™
other standard audio jack.
The upper part of the QUICK DISCONNECT (attached to the A40 Headset
itself) contains a mute control that shuts off any outgoing voice signals. To
plug either of the two included headset cables into the QD, make sure you
have the 2.5mm and 3.5mm connector jacks properly aligned (one is smaller
and one is larger).
