Audio connection
48V
phantom power is required by some condenser microphones (e.g. studio microphones and large
diaphragm models). If a condenser microphone that requires 48V phantom power is connected to Jack 3
(leftmost), enable the 48V phantom power by pressing the
48V
key (18) so that it lights. If the 48V
indicator is not lit, Jack 3 will still have 5V phantom power present, which can power headset or lavalier
condenser microphones. For dynamic microphones, the 48V phantom power should be switched off.
The
BT
key (20) is for pairing Bluetooth to the X-PAD for audio playback from a sending device, such as a
smart phone, tablet computer or an audio player with Bluetooth pairing capability. Briefly pressing this key
will cause it to flash quickly, indicating that the X-PAD is in pairing mode.

on the sending device (smart phone, tablet etc.) and select to pair. When paired
successfully, the BT key will flash more slowly to indicate a successful connection.
Playback of audio from the sending device will now be received wirelessly to the BGM channel of the X-
PAD. Pressing the BT key again switches off the Bluetooth receiver and disconnects the wireless link from
the sending device.
