Vszerda USB 6 Channel 5.1/7.1 Surround External Sound Card

SKU CH-RZB0-PRP0E

A compact USB adapter adds 5.1 or 7.1 surround sound with optical digital I/O and supports 32, 44 and 48 kHz sampling rates

  • 6-channel 5.1/7.1 surround audio for immersive playback
  • USB connection adds full-duplex audio to any PC or Mac
  • Digital recording via SPDIF input sent back over USB
  • Supports 32 kbps, 44 kHz and 48 kHz sampling rates
  • Compact metal housing measures 89×69×21 mm

Versatile Audio Interface

The Vszerda USB 6 Channel sound card adds full-duplex audio playback and recording to any PC, Mac, laptop, desktop or tablet. It supports 5.1 and 7.1 surround configurations through six analog channels for immersive listening. An optical adapter handles digital input and output using AES/EBU, IEC 60958 and S/PDIF standards. This makes it suitable for home recording, karaoke and general multimedia use.

Silent Passive Operation

The unit has no moving parts and draws power directly from the USB bus, so it adds no audible noise to a quiet room. Its metal enclosure measures 89 by 69 by 21 millimetres and acts as a passive heatsink, keeping the electronics cool during normal playback. Digital recording accepts 32 kHz, 44 kHz and 48 kHz sample rates, while analog playback operates at 48 kHz. No external power supply is required for typical desktop use.

Consistent Sustained Performance

Because the device is bus-powered and passively cooled, thermal throttling does not occur during long recording or streaming sessions. The fixed 48 kHz analog output rate and supported digital sample rates remain stable over extended periods. Full-duplex operation allows simultaneous capture and playback without dropouts, provided the host software supports the chosen sample rate. The compact metal shell maintains its temperature equilibrium indefinitely.

Questions about this item

How do I install the Vszerda USB 6 Channel sound card on my laptop, and what step is often missed?

Connect the supplied USB cable from the sound card to a free USB port on the laptop; the step often missed is selecting the device as the default playback and recording device in the operating system sound settings after the driver installs automatically.

What maintenance or replacement will the Vszerda USB 6 Channel sound card need over time?

The unit has no moving parts or user-replaceable components; keep the metal casing and the USB connector free of dust and debris, and replace the supplied USB cable only if it becomes physically damaged.

What is the first limit I will hit with the Vszerda USB 6 Channel sound card during sustained recording sessions?

The digital recording path is fixed at 48 kHz sampling, so extended sessions cannot exceed that rate; the USB interface and the SPDIF standards (AES EBU, IEC 60958) define the bandwidth ceiling.
