Blackmagic Design Teranex Mini Audio to SDI 12G Blackmagic Design

Podrobný popis

Blackmagic Teranex Mini Audio to SDI 12G is a professional converter that embeds audio into 12G-SDI video. It adds two channels from balanced XLR, unbalanced RCA or optical S/PDIF, or up to four channels of AES/EBU, into any SDI signal from SD to DCI 4K. Audio from mixers, players and analog recorders thus travels together with the picture to routers and recorders.

Embed audio into 12G-SDI

Combine audio from mixers, players or analog recorders with a professional SDI video path for routers, recorders and studio distribution.

12G-SDIXLR + RCATOSLINK4× AES/EBUBuilt-in power supply

Extremely low noise

The analog audio inputs feature an extremely low noise floor below −115 dBFS, so even analog background noise is virtually silent.

2 channels

Balanced XLR or unbalanced RCA.

4 channels

Professional AES/EBU.

TOSLINK

Optical S/PDIF input.

16 channels

Embedded SDI audio support.

Multi-rate SDI output

The converter accepts a 12G-SDI video input and creates a reclocked 12G-SDI output with the selected audio embedded. Automatic operation covers SD, HD, 2K, Ultra HD and DCI 4K.

Measured noise floor

The audio floor graph of the Teranex Mini Audio to SDI 12G converter shows a value of around −115 dBFS on both channels (RMS via FFT).

Audio from the mixer

Full size XLR connections are built right into the converter, so audio from mixers, effects processors, compressors or limiters can be embedded into SDI systems without extra adapters.

Teranex Mini Smart Panel

The optional Teranex Mini Smart Panel replaces the front cover of the converter: remove the two screws on each side, pull the cover off and screw the panel on. The color LCD then shows the video passing through, while the buttons and rotary knob open a settings menu right on the unit – ideal in the field without external monitors and in racks full of converters.

Settings via mini switches, USB and Ethernet

Core functions are selected with mini switches using the diagram printed on the underside of the converter. From a Mac or Windows computer, the converter can be set up and updated over USB or Ethernet with free software, so even larger installations with many converters can be managed remotely.

In the rack or on the desk

The compact converter can sit on a desk, hide behind equipment or be rack mounted – the optional Blackmagic Universal Rack Shelf (1U) holds Teranex Mini together with other 1/3 and 1/2 rack width Blackmagic products. Crossflow cooling with a heat pipe keeps the converters running even when mounted side by side.

Connections

The rear has an IEC power connector, Ethernet with PoE+, a 12G-SDI input and output, an optical S/PDIF input (TOSLINK), two RCA connectors and two XLR audio connections; the front has USB and the mini switches.
