analog or digital—on a piece of hardware (such as the 16 mic/line XLR input

jacks on the 6416m Mic Input Module). Each of these audio inputs can be

made active and added to the network individually, and it is only when

activated that they use any network resources (the A‑Net Slots). To enable this

powerful feature, Pro64 products separate the hardware resources from the

available network resources with a button that allows each hardware input

channel it to be added to the network as needed.

It is these activated hardware resources that are being referred to as “Slots.”

Pro64 audio networks can potentially have a greater number of audio

channels and hardware I/O devices connected than the network can make

use of at one time. This provides flexibility without requiring constant re‑

patching or complicated computer programming.

Keep in mind that a Pro64 A‑Net network can only manage a specific number

of Slots at a time, and this number varies with the sample rate being used.

The maximums are 64 Slots in Auto Mode at the 48kHz sampling rate and

64x64 Slots in Manual Mode at 48kHz.

In summary, think of “channels” as hardware resources that can be added

to the network as needed and “Slots” as locations within the digital audio

network pipeline that A‑Net uses to move data throughout the network.

Slots and Sample Rate

The current system‑wide sample rate will determine the number of A‑Net

Slots that are available. Auto Mode and Manual Mode have the same number

of Slots at each sample rate; only the direction of the data is different.

Even though the network sample rate may change the available number of

A‑Net Slots, the capacity of a hardware device does not change. That is, a

16‑channel input module in a 192kHz network can still have all of its channels

activated; all of its physical inputs can operate at 192kHz.

The current sample rate will also affect the display of available A‑Net Slot

ranges. Slot ranges will always have the same maximum number as seen in

the sample rate chart. At 96kHz, for example, only Slots numbered 1 through

32 are available; the Slot range from 33 to 64 is inactive and unavailable at

that sample rate. Slot ranges outside the maximum for the current sample

rate can be selected, but attempting to activate a channel in an unavailable
