A

Grounding screw

For safety, use this screw to ground the AD8HR. The
included power cable has a three-pin plug. If the AC
outlet is grounded, the AD8HR will be grounded
correctly via the power cable. If the AC outlet does not
provide a suitable ground, this screw must be
connected to a suitable ground point. Grounding is
also an effective method for eliminating hum,
interference, and other noise.

B

[AC IN] connector

Connect the included power cable here. First, connect
the power cable to the AD8HR, then insert the power
cable plug into the AC outlet.

C

[HA REMOTE] connector 1

This D-sub 9-pin connector is used to connect a
computer or Yamaha PM5D Digital Console or

multiple AD8HR system, connect an AD8HR to [HA
REMOTE] connector 1 on an additional AD8HR.
NOTE:

Please visit the following Yamaha website for the latest
information about the devices that can control the AD8HR
