Mic Mute LED
Turns RED when the mic is muted and GREEN when the mic is on.
Mic Mute Switch
When “ON”, the microphone is muted so you won’t be heard by other players
online.
Expander Switch
When “ON”, the Expander widens the stereo sound eld so you can hear
more of the sounds on the left and right sides and less in the middle. This
can help you hear distant sound cues in the game.
Bass Boost
Sets the intensity of bass boost level applied to the game audio.
Chat Boost™ LED
The intensity of this blue LED indicates the amount of Chat Boost applied
to the chat signal. The LED intensity increases as Chat Boost increases the
level of teammates’ voices in response to louder game sound.
Chat Volume
Sets the minimum level of incoming chat from other players on the PlaySta-
tion Network. The Chat Boost feature will automatically increase this volume
as the game sound increases, as indicated by the blue LED intensity.
Game Audio Volume
Sets the game sound level.
XBOX LIVE Jack:
When using the PX21 with an XBOX 360, connect the included XBOX LIVE
talkback cable from this jack to the XBOX controller for XBOX LIVE chat.
Mic Monitor (not shown)
When the mic is not muted, you’ll hear yourself speak in the headphones, so
you won’t shout as much when talking online.
