DB25 Audio Thru/Alternate In
Two female DB25 multipin connectors are provided for audio throughput on
the 6416m, creating a passive split of the source signals. Channels 1‑8 appear
on one DB25 jack and channels 9‑16 on the other. The DB25s are wired to the
industry accepted Tascam® compatible analog wiring standard. Do not use
DB25 cables wired for AES3 digital connections.
The DB25 Audio Thru connection allows audio signals connected to the
6416m XLR input jacks to be connected to another input device such as
a mixing console or Digital Audio Workstation (DAW) interface without
interrupting the signals connected to the Pro64 network.
Alternate Input
The DB25 Audio Thru connections can also be used as an optional main input
path. Signals connected to the DB25 connections will be metered and can be
made active on the network in the same manner as the XLR inputs.
When used in this manner, the XLR connectors would have no signals
connected to them, but could be used as a passive split output if appropriately
wired cables are provided.
For input connections, always use DB25 cables wired to analog audio
standards; never connect multipin cables wired for AES3 digital connections.

ote
: Do not use the XLR jacks and DB25 Alternate In connections for
inputs to the same set of channels on the 6416m simultaneously.
DB25 Pinout
Breakout cables for DB25‑to‑TRS, DB25‑to‑XLR connections, etc., are readily
available. To create a custom cable for the Audio Thru/Alternate In function,
use the following table and diagram.
Note that there are several DB25 pinouts commonly in use, including two
used for AES3 digital connections. The digital pinouts are not compatible
with the analog outputs of the 6416m Audio Thru connectors. Use only those
cables wired for the Tascam analog audio pinout.
