Using An External Head Amp - Yamaha CL5 Reference Manual

Using an external head amp

If an I/O card (such as an MY16-ES64 card) supports the remote protocol of an external head amp in
the CL's slot, you will be able to remotely control from the CL console some parameters of the external
head amp (Yamaha SB168-ES or AD8HR), such as phantom power (+48V) on/off status, gain, and HPF.
For details on the I/O card settings, refer to the owner's manual for the I/O card.
Connecting the CL series console to an AD8HR
To remotely control the AD8HR from the CL series console, install an MY16-ES64 EtherSound card in
Slot 1 on the CL unit, then use an Ethernet cable to connect the CL unit to the NAI48-ES. Then, connect
the HA REMOTE connector on the NAI48-ES to the HA REMOTE 1 connector on the AD8HR using
an RS422 D-sub 9-pin cable. This connection enables you to remotely control the AD8HR from the CL
series console.
To transmit audio signals (input to the AD8HR) to the CL series console, connect the DIGITAL OUT
A (or B) connector on the AD8HR to the AES/EBU connector on the NAI48-ES using a D-sub 25-pin
AES/EBU cable. Signals will be sent or received between the NAI48-ES and the CL series console via
the MY16-ES64 card.
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 connector to the second AD8HR's
HA REMOTE 1 connector. If you use the NAI48-ES, you can connect up to six AD8HR units. In this
case, to input AD8HR's audio signals into the CL series console, install two MY16-EX cards on the CL
unit since each slot on the CL unit accepts up to 16 channel signals. Then, connect each two of the third
and subsequent AD8HRs to each AES/EBU connector using a D-sub 25-pin AES/EBU cable.
