Using An External Head Amp; External Head Amp Connections - Yamaha M7CL Owner's Manual

If you connect an external head amp that supports remote control via a dedicated protocol
(Yamaha AD8HR) to the M7CL's REMOTE connector, you will be able to remotely control param-
eters such as the phantom power (+48V), gain, and HPF of each channel from the M7CL.

External head amp connections

Here we will give the example of connecting the Yamaha
AD8HR.
In order to remotely control the AD8HR from the M7CL,
use an RS422 D-sub9 pin cable to connect the REMOTE
connector located on the M7CL's rear panel to the
AD8HR's HA REMOTE 1 connector. This connection
allows the M7CL to remotely control the AD8HR.
So that the signals input to the AD8HR will be sent to the
M7CL, use a D-sub25 pin AES/EBU cable to connect the
AD8HR's DIGITAL OUT A (or B) to an I/O card installed
in a slot of the M7CL.

Alternatively, you can use a "daisy chain" connection to
remotely control multiple AD8HR units simultaneously.
To do this, connect the AD8HR's HA REMOTE 2 connec-
tor to the second AD8HR's HA REMOTE 1 connector. If
you use three Yamaha MY16-AE units, you can connect
up to six AD8HR units.
