Part Names and Functions
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.
[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.
Be sure to use the included power cable.
Use of other cables may result in malfunction,
heat generation, or ﬁre.
[HA REMOTE] connector 1
This D-sub 9-pin connector is used to connect a
computer or Yamaha PM5D Digital Console or
DM2000 to control the AD8HR remotely. In a
multiple AD8HR system, connect an AD8HR to [HA
REMOTE] connector 1 on an additional AD8HR.
Please visit the following Yamaha website for the latest
information about the devices that can control the AD8HR
[PC RS422] switch
If you connect a computer to [HA REMOTE]
connector 1, set this switch to PC. If you connect a
Yamaha PM5D or DM2000, or an additional AD8HR
in a multiple AD8HR system, to [HA REMOTE]
connector 1, set this switch to RS422.
[HA REMOTE] connector 2
In a multiple AD8HR system, connect one AD8HR to
this D-sub 9-pin connector on another AD8HR.

data routed from Channels 1–4, and the [DIGITAL
OUT B] connector outputs digital audio data routed
from Channels 5–8.
