Supported Remote Control Features
When using Pro64’s m‑control feature, note that only parameters available natively on the Yamaha control surface
itself and supported by the Yamaha interface can be controlled on Pro64 mic preamps remotely. These include
channel preamp gain, low cut filter (referred to as a high pass filter in the Yamaha interface), and +48V phantom
power on the 6416m and AllFrame. The 6416m has a fixed 85Hz low cut filter, while Yamaha consoles offer a
variable range High Pass Filter (abbreviated as HPF) in their user interface. When using Yamaha remote control
with Aviom preamps, you can turn this filter on and off, but the cutoff frequency remains fixed at 85Hz. Editing
the HPF filter cutoff frequency from the Yamaha user interface will have no effect at the Pro64 mic preamp; the
cutoff frequency remains fixed at 85Hz.
The Pro64 mic preamp’s pad setting is controlled indirectly through the head amp gain setting on the console.
There is no direct command for turning the Pro64 mic preamp pad on or off from the Yamaha control surface.
Physical Connections
Remote control commands between the Yamaha host console and Pro64 remote mic preamps are sent
using RS‑422 communication. Many Yamaha devices have DB9 RS‑422 jacks on their rear panel, while some
others send remote control communication directly to external devices via the console’s multipin backplane
connector where the MY format expansion cards connect to the console’s circuit board.
For Yamaha devices with a DB9 jack for remote HA control, a DB9 serial cable must be used to connect the console
to the 6416Y2 card set up for m‑control. No additional connections are required anywhere in the network, as all
remote control commands are managed by the Pro64 devices and transmitted via the network cabling.
In Pro64 systems where more than one 6416Y2 A‑Net Interface Card is installed in a Yamaha console, only one of
the 6416Y2 cards should be set to provide m‑control communication and messaging between the Yamaha host
and the Pro64 network. This one card will manage remote control communication for all 6416Y2 cards in the host
console.
This card must be installed in the Yamaha device’s expansion slot #1.
