A14MKII Stereo Integrated Amplier
If you are using terminal lugs, connect them to the wires. If you are attaching
bare wires directly to the binding posts, separate the wire conductors and
strip the insulation from the end of each conductor. Be careful not to cut
into the wire strands. Unscrew (turn counterclockwise) the binding post
thumbscrews. Place the connector lug or wire around the binding post
shaft. Turn the thumbscrews clockwise to clamp the connector lug or wire
rmly in place.
NOTE: Be sure there are no loose wire strands that could touch adjacent
wires or connectors.

AAC and APTX Bluetooth audio streaming.
Rear USB Power Port
p
The rear USB port provides 5V/0.5A for charging or powering USB devices
including streaming music players. This port does not allow playback of audio.
The port can be congured to remain powered even when the A14MKII
is in standby mode through the front panel setup menu (See USB POWER
option on page 14).
This conguration option allows the attached streaming source to remain
powered for use with the Signal Sense function for automatic power on/
off control of the amplier.
NOTE: When configured to provide continuous power to the rear panel
USB port the A14MKII will consume additional power even when in
standby mode.
