Head Amp Control
The Rio head amplifiers can be remotely controlled from a 
host device, such as a compatible Yamaha digital mixing 
console. 
Control from an Rio-native 
Device
The Rio head amplifiers can be controlled remotely from 
an Rio-native digital mixing console, such as a CL series 
product.
The connected Rio-native device displays the model name 
and UNIT ID number of the corresponding Rio unit to be 
controlled.
If you plan to connect a device that features Rio native 
support to monitor and control the head amplifiers, refer to 
the owner’s manual for the corresponding device.
Control from a Device That 
Does Not Feature Rio-Native 
Support
This section explains how to configure the Rio settings that 
are required to control the Rio as AD8HR units from a 
device that does not feature Rio-native support.
For more information, please refer to the “Dante-MY 
16-AUD & R Series HA Remote Control Guide” that is 
downloadable from the website listed below.

NOTE
The following Yamaha non-Rio-native devices enable you 
to control the Rio as AD8HRs. To connect such a device, 
first install a Dante-MY16-AUD card (firmware version 3.3.8 
or later) into the Mini-YGDAI slot.
M7CL, LS9, DM1000, DM2000, PM5D/DSP5D, 
DME64N/24N
Setting the DIP Switches
While the power to the unit is off, flip DIP switch 5 down 
and DIP switch 6 up.
NOTE
If REMOTE has been set to [AD8HR], START UP MODE 
will be set to [RESUME] regardless of the DIP switch 
setting.
Setting the UNIT ID
The Rio3224-D will be assigned four virtual IDs (as 
AD8HR Device IDs) if the DIP switches are set to 
[AD8HR]. The Rio1608-D will be assigned two virtual IDs 
if the DIP switches are set to [AD8HR].
If you combine Rio3224-D and Rio1608-D or add an 
AD8HR or SB168-ES in the network, make sure that the 
virtual IDs or Device IDs are all unique. The Rio UNIT IDs 
and virtual IDs are organized as follows:
Set the Rio correctly so that you can control it as AD8HRs. 
In addition, scene recall can be used to recall all head 
amplifier settings at once. Refer to the digital mixing 
console owner’s manual for details on head amplifier 
control.
