PROZOR 192kHz DAC Audio Adapter

The PROZOR FBA_4330141664 converts coaxial or Toslink digital PCM signals to analog stereo RCA and 3.5mm jack outputs simultaneously. It supports sampling rates of 32, 44, 48, 96 and 192 kHz at 24-bit depth. The aluminium casing provides heat resistance and anti-interference shielding. It is suited for connecting TVs, disc players or game consoles to amplifiers or powered speakers.

Simple USB-powered installation

The unit is powered by an included 5.5mm USB cable but requires a dedicated 5V 1A power adapter which is not supplied. Using any other plug specification will cause malfunction. Input and output cannot be reversed. Some Panasonic TVs need the audio output set to SPDIF, while Samsung TVs require external speakers enabled in the sound menu. Compatibility issues have been reported with YouTube and Netflix streaming apps.

Stereo analogue output with 192kHz headroom

The DAC handles PCM streams up to 192kHz/24-bit and down-mixes to two-channel analogue via gold-plated RCA and 3.5mm sockets. It does not decode Dolby, DTS or 5.1 surround formats, so multi-channel sources must be set to PCM or stereo output. Volume is adjustable via the front knob for direct level control. The adapter provides no headphone amplification or digital output pass-through.

Questions about this item

How can I confirm the 192kHz DAC is converting the Toslink signal correctly after connecting it?

Play audio from the source; sound should appear on both the RCA and 3.5mm outputs simultaneously, and the volume knob should change the level smoothly without noise when no signal is present.

What cables and accessories are included, and what must I provide separately?

The box contains the DAC unit and a 1 m Toslink cable; you must supply a 5 V 1 A USB power adapter and any RCA or 3.5mm interconnects for your amplifier or headphones.

Which version should I choose if I need both RCA and 3.5mm outputs with volume control?

This single model FBA_4330141664 provides both RCA stereo and 3.5mm jack outputs together with the built-in volume knob, so no other version is required.
