Digital Audio Converter with Bluetooth 5.0

This Jansicotek unit converts optical SPDIF, USB flash drive, or Bluetooth 5.0 digital sources into analog stereo output through RCA and 3.5 mm jacks. It targets listeners who want to connect modern digital devices to older amplifiers or powered speakers without a built-in DAC. The converter handles PCM and LPCM formats at sampling rates of 32, 44.1, 48, 96 and 192 kHz with 24-bit depth.

Installation and Common Issues

Power the converter via the included USB cable, select the active input, then adjust the volume knob or remote for level control. Optical and USB inputs accept only PCM or LPCM streams; compressed formats such as Dolby Digital or DTS will not decode and produce silence or noise. Bluetooth pairing follows standard device discovery, but multipoint connection is not supported.

Deciding Specification — Headphone Amplifier Power

The built-in headphone stage delivers 125 mW per channel into 32 ohms and supports loads from 16 to 300 ohms. This output level determines whether the converter can drive your headphones to sufficient volume without an external amplifier. If your headphones require significantly more power, this unit will not meet that need.

Questions about this item

How do I know the 192KHz DAC is working after connecting my TV via optical?

Play audio and confirm sound comes from both the RCA and 3.5mm outputs at the same time; the front-panel volume knob should change the level on both.

What comes in the box and what cables do I still need to buy?

The package includes the converter, a USB power cable, an IR remote and a manual; you must supply your own optical Toslink cable and RCA or 3.5mm interconnects.

Which input should I choose — Bluetooth 5.0, USB or optical — for 192KHz 24-bit playback?

Use the optical Toslink input; it accepts PCM/LPCM at 32, 44.1, 48, 96 and 192KHz. USB and Bluetooth are limited to lower rates.
