SKU CH-C29X-C6289

Bi-directional audio converter links coaxial and Toslink S/PDIF with built-in signal amplification for 24-bit 192KHz audio

  • Bi-directional conversion between Coaxial RCA and Toslink Optical
  • Built-in amplifier preserves signal integrity without loss
  • Supports 24-bit depth with sample rates up to 192KHz
  • Metal enclosure reduces EMI/RF interference for reliable operation
  • Plug-and-play design requires no software installation

Professional Audio Converter

The Sony Mobile Pro A/V Extender & Repeater is a bi-directional audio converter designed for installers and enthusiasts who need to bridge Coaxial RCA and Toslink Optical S/PDIF interfaces. It accepts a digital audio signal on either port and outputs it on the other, making it suitable for connecting legacy and modern AV components without format mismatch.

Signal Integrity and Format Support

A built-in digital audio signal amplifier maintains signal integrity without loss across the conversion path. The device supports LPCM, AC3, and DTS audio streams at 24-bit depth with sample rates up to 192KHz. Direction is selected via built-in switches, and operation is plug-and-play with no software installation required.

Metal Enclosure and Connectivity

A sturdy metal enclosure provides durability and minimises EMI/RF noise interference for dependable performance. The unit is powered via an included Micro USB cable, so a USB power source must be available at the installation point. It is not suited for buyers who require analogue conversion, multi-channel extraction, or HDMI audio de-embedding.

Questions about this item

Does the metal enclosure or the built-in amplifier need any periodic maintenance to keep the signal clean?

The unit has no user-serviceable parts; the metal chassis and internal amplifier are sealed, so no routine maintenance is required.

What audio format or sample-rate ceiling will I hit first when running high-resolution material continuously?

The converter tops out at 24-bit depth and 192 kHz sample rate, so any LPCM, AC3 or DTS stream beyond that will be the limiting factor.

How much heat or noise does the device produce when powered through the Micro USB cable all day?

It draws power from a Micro USB connection with no fan, so it runs silently and stays cool to the touch during continuous operation.
