control
determine a Pro64 product’s firmware version and to update it to the latest version. The current version of the
Pro64 Network Manager application and all associated Pro64 firmware update files are available on the Aviom
website free of charge. For best performance always use the latest revision of the firmware in all Pro64 devices.
DB9 Cables
Using m‑control requires at least one 6416Y2 and one 6416m or AllFrame. A DB9 serial cable connected between
the Yamaha device and the Aviom 6416Y2 card is required to make use of this feature on most consoles. Do not
use a null modem type cable; null modem cables are typically used with RS‑232 communications while serial
cables are used with RS‑422. Place DIP switch #1 in block SW8 in the up position when using a serial cable. (The
down position should be used with a null modem cable only when connected to a PC for firmware updates, etc.)
The LS9 does not require an external DB9 remote control connection as its control data is passed from the console
to the 6416Y2 card internally through the backplane connector that is part of the console’s circuit board at the
rear of the MY expansion card slot. The setting for DIP switch #1 in block SW8 does not affect the LS9.
Remote Control Emulation
Aviom and Yamaha use different remote control architectures, and in order to provide the convenience of console‑
based control, Aviom emulates Yamaha’s remote control scheme and presents remote controllable mic pre
channels as “virtual devices” to the Yamaha console. Yamaha host devices associate external remote controllable
mic preamps, referred to as Head Amp (HA) Devices, with their mini‑YGDAI (MY) expansion card slots.
The most common remote controllable mic preamp connected to these consoles is the Yamaha AD8HR, an
8‑channel device, so remote controllable Aviom channels appear to the console as AD8HR devices in units of 8
channels, and all text and graphics in the Yamaha user interface will refer to external AD8HRs. While each block of
eight channels appears to the console as one virtual device, there is no requirement that the channels originate
on the same 6416m Mic Input Module or AllFrame.
Similarly, there are differences in the functions for which Aviom and Yamaha provide remote control. In addition,
the language used to describe these settings is different. For instance, while Aviom mic preamps can be muted
remotely, Yamaha provides mute control only in the console (i.e., outside the A‑Net network). Users who wish to
have remote control of the Pro64 channel mute at the preamp must use an MCS Mic Control Surface for remote
control. When using m‑control console‑based remote control, the RCI and MCS can still be used with the Pro64
network as an alternative means of providing control and network monitoring. In addition, Pro64 Network
Manager can also simultaneously be used as a control source for all channel‑based functions.
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.
