Inputs & Outputs
Standard Definition video is always output using HD Mode because 3G does not support Standard
Definition.
The output video stream contains up to 16 tracks of embedded audio for SDI and 8 tracks for HDMI.
Timecode and record start and stop flags are included on the SDI output.
Timecode overlay can be added to the HDMI and/or SDI output signal in
[Video - Video Output OSD]. The timecode overlay is displayed in various colors to indicate the cur-
rent transport state of the PIX 270i: White = Stopped, Red = Record, Green = Playback.
Audio Inputs
The PIX 270i can record up to 64 tracks from a variety of audio input sources in both Video and Au-
dio modes:

Maximum amount of recording tracks is affected by sample rate. (See “Recording”, page 25)
Analog Audio Inputs
The PIX 270i 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 82). Channels 1 and 2
of this connector are summed with channels 1 and 2 XLR Analog Audio Inputs, respectively.
Digital Audio Inputs
The PIX 270i accepts digital audio from HDMI, SDI, AES/EBU, MADI, and Dante inputs. All digital
inputs are sample rate converted. This helps ensure synchronization of digital audio from multiple
sources. In Video Mode, audio is sampled at 48kHz. In Audio Mode, the sample rate is determined
by the [Audio - Audio Mode Sample Rate] when [Timecode/Sync - Sync Ref - Audio Only] is set
to Internal. Otherwise, the Audio Mode sample rate is determined by the selected synchronization
reference.
