The 970 can record up to 64 tracks from a variety of input sources:
Input Type Count Connector(s) Gain Details
Analog 8
1-8: DB-25 (CH 1-8 LINE IN)
1-2: XLR (LINE IN 1/2)

Balanced, Line-level. Channels 1-2 on DB-25
connector are summed with respective XLR con-
nectors.

Analog Inputs
The 970 has eight, high-performance, line-level analog audio inputs.
XLR (1-2)
The XLR balanced inputs accept line-level signals. These inputs are shared with Channels 1 and 2 of
DB-25 Analog Audio Input connector. Channels 1 and 2 of this connector are summed with channels
1 and 2 of the DB-25 connector, respectively.
DB-25 (1-8)
Eight analog, line-level inputs are provided on the DB-25 Analog Audio Input connector. This con-
nector is wired in the Tascam fashion (
See “Connector Pin Assignments”, page 56
). Channels 1 and 2
of this connector are summed with channels 1 and 2 XLR Analog Audio Inputs, respectively.
Digital Inputs
The 970 accepts digital audio from AES3, MADI, and Dante sources. The sample rate is determined
by the
[Audio - Sample Rate]
when
[Timecode/Sync - Sync Ref]
is set to
Internal
. Otherwise, the
sample rate is determined by the selected synchronization reference. All digital inputs are sample
rate converted. This helps ensure synchronization of digital audio from multiple sources.
AES3
AES3 Inputs 1 to 8 are derived from the AES3 DB-25 connector on the rear panel. This connector also
carries 8 channels of AES3 Output ( See “Connector Pin Assignments”, page 56 ). AES3 Input signal
with sampling rates from 32 kHz up to 192 kHz and bit depths up to 24-bits is accepted.
MADI (AES10)
MADI Inputs 1 to 64 are derived from the MADI Input BNC connector and the MADI Input SC
(optical) connector on the rear panel. The MADI connector used is configured with Setup Menu op-
tion [Audio - MADI Input] . When this option is set to Auto-Detect , signal for each channel will be
derived from whichever MADI Input connector has signal. If signal is present on the same channel
in both MADI Input connectors, the signal from the SC (optical) connector will be used.
