Remote Control
A special protocol enables you to control the AD8HR
from a computer or Yamaha PM5D or DM2000 that is
connected to [HA REMOTE] connector 1. You can
also remotely control up to 255 AD8HRs that are
connected to one another. However, the maximum
number of AD8HRs that can be controlled remotely
depends on the type of connected device.
When each AD8HR receives control signals, the Gain
display indicates the ID number of the corresponding
unit. This is useful when you wish to identify each of
multiple AD8HRs that are connected in a system.
When you operate the panel on the unit, its ID
number on the Gain display disappears. The ID
number of the AD8HRs is determined based on the
connection order in the daisy chain.
You can also create a daisy chain connection that
mixes AD8HRs and Yamaha AD824 AD converters.
However, in such a system, any AD8HR that is
connected after any AD824 unit (when seen from the
host device; e.g., computer) will be recognized as an
AD824, and you will be unable to control the
following functionality on these AD8HR units. For
this reason, we recommend that you connect all
AD8HR units closer to the host than any AD824 unit.
• High pass filter on/off and cutoff frequency cannot
be controlled
• Gain adjustment will be in 6 dB steps
• [+48V MASTER] switch on/off status cannot be
monitored
If a computer is connected to [HA REMOTE]
connector 1, set the [PC RS422] switch to PC. If you
connect a Yamaha PM5D or DM2000, or another
AD8HR in a multiple AD8HR system, to [HA
REMOTE] connector 1, set this switch to RS422.
NOTE:
• If you are remotely controlling the AD8HR from a device
that supports only the AD824, the device will recognize all
AD8HRs as AD824s.
• When remotely controlling the AD8HR from a Yamaha
DM2000/DM1000, all AD8HR units may be recognized as
AD824 units and some functionality may be limited unless
the DM2000/DM1000 firmware is V2.0 or later. For the
latest information, refer to the following website.
http://www.yamahaproaudio.com/
• If you are connecting the [HA REMOTE] connectors on
two AD8HRs to each other, be careful to avoid loop
connection.

Wordclocks
Wordclocks
For proper AD conversion and digital audio data transmission and reception, the D8HRs and external
digital audio devices must lock to an identical wordclock. The AD8HR is capable of transmitting a
wordclock signal of 44.1kHz, 48kHz, 88.2kHz, and 96kHz, you can use the AD8HR as the wordclock
master and the external devices as wordclock slaves. The AD8HR can also lock to the wordclock signal
received at the [DIGITAL OUT A] connector or [WORD CLOCK IN] connector.
AES/EBU Connections
WORD CLOCK jack connection
Use an AES/EBU cable to transmit digital audio data
and receive a wordclock signal on the AD8HR.
NOTE:
In Double Channel mode, the AD8HR will run at a clock
rate that is twice (88.2/96kHz) the clock (44.1/48kHz)
received at the [DIGITAL OUT A] connector. In Double
Speed mode, the AD8HR will run at a clock rate that is the
same as the wordclock (88.2/96kHz) received at the
[DIGITAL OUT A] connector.
The AD8HR can receive wordclock signals at the
[WORD CLOCK IN] connector. The [WORD CLOCK
IN] connector and [WORD CLOCK OUT] connector
can also be connected in series to allow multiple
AD8HR units to receive a wordclock signal.
The AD8HR’s [WORD CLOCK IN] connector is
terminated at 75 ohms. Do not use a “T” connector to
make connections.
