Digital SPDIF Coaxial Toslink Converter

The Lindy 70457 is a bi-directional converter that translates between optical Toslink and coaxial SPDIF digital audio signals. It handles LPCM stereo plus Dolby Digital and DTS up to 5.1 channels at sample rates up to 192 kHz. The compact plastic housing measures 60.5 x 54 x 20.5 mm and weighs only 0.04 kg. It is suited for anyone needing to link equipment that uses different digital audio interfaces.

USB-Powered Signal Bridge

Power comes from a 5 V DC 1 A supply via a Mini USB port, so a spare USB socket on a TV, amplifier or charger is all that is required. Both input and output present a 75 ohm impedance with 1 V RMS output level, and the signal-to-noise ratio reaches 142 dB with frequency response of ±0.5 dB. The converter adds no video path, freeing HDMI ports for picture-only connections while keeping multichannel audio intact.

Upgrade From Single-Format Adapters

This unit replaces fixed one-way adapters or cables that only work in a single direction. The jump is worthwhile when a source and a sink use mismatched digital audio ports and the system must switch between them without rewiring. It does not suit installations that require analogue conversion, HDMI audio extraction, sample-rate conversion beyond 192 kHz, or more than two digital audio channels in formats other than LPCM, Dolby Digital or DTS.
