still be used with the Pro64 network as an alternative means of providing
control and network monitoring.
Likewise, Yamaha displays mic gain settings using a convention that is
different from what Aviom and some other manufacturers use (for example,
a range from +10dB (minimum) to ‑62dB (maximum). The exact values vary
by product. These are really just two different ways of displaying the same
type of information. Yamaha’s method shows the level of the incoming
signal; for example, when the console HA gain setting is “‑32,” the console
is trying to tell you “the level of your incoming signal is ‑32dB.” On a 6416m,
if the corresponding gain readout is “25,” the 6416m display means “you are
adding 25dB of gain to the incoming signal.” Control settings sent from a
Yamaha device will be interpreted by the 6416m automatically and displayed
accordingly. There is no need for the user to make any translations between
the two approaches to displaying the data.
Supported 6416m 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 the 6416m Mic Input Module 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. 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 6416m 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 6416m; the cutoff frequency remains fixed at 85Hz.
The 6416m pad setting is controlled indirectly through the head amp gain
setting on the console. There is no direct command for turning the 6416m
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,
