Weiss Engineering INT204 USB to AES/EBU or S/PDIF Interface/DSD to PCM Converter

If your DAC lacks a USB input, reach for the Weiss Engineering INT204 to play back audio from your computer. It takes the USB audio input stream and outputs it as either AES/EBU or S/PDIF. Connect it to your DAC and enjoy the computer audio with pristine digital-to-analog conversion. The INT204 also handles DSD to PCM conversion, at the sample rate and wordlength of your choice.

USB CONNECTIVITY FOR YOUR DAC

The INT204 allows you to play back audio from a USB-equipped computer through a non-USB-equipped DAC. It takes the incoming USB audio stream and outputs it in AES/EBU or S/PDIF formats. You can now enjoy audio from your computer through your DAC, even if it does not have a USB input.

DSD TO PCM CONVERSION AND VOLUME CONTROL

You can also convert DSD audio from the computer to PCM audio for your DAC. The INT204 makes your trusted D/A converter DSD capable, with selectable sampling frequency and word length. With the optional remote control, it is possible to control the audio volume in the digital domain. The remote control is purchased separately.

CLOCKING AND POWER

To ensure a high-quality transfer, the INT204 includes an internal clock generator for low-jitter performance. It uses dual power sources — both USB bus power from the computer and its own included power supply. This means the input and output sections can be separately powered and thus galvanically isolated for low-noise performance.

SOFTWARE FEATURES

The INT204 can do DSD to PCM conversion at selectable sampling frequencies and word-length (88.2 or 176.4 kHz and 16 or 24-bit). The DSD input is in the DoP format with a sampling frequency of DSD64 (2.8224 MHz) or DSD128 (5.6448 MHz).

Supported PCM sampling frequencies are all standard frequencies between 44.1 kHz and 384 kHz. The sampling frequency of 352.8 kHz is automatically converted to 176.4 kHz and the sampling frequency of 384 kHz is converted to 192 kHz as the AES/EBU or S/PDIF formats do not support sampling frequencies higher than 192 kHz.

FEATURES:

• Two power sources are required for the INT204 - the bus power fed via the USB connector and external power supply which is supplied with the INT204 unit (this allows the input and output sections of the INT204 to be galvanically isolated)
• The sampling frequency is generated with an internal generator in the INT204 ensuring that the transfer between computer and D/A Converter is low jitter
• USB type B connector is used to connect to computer
• One XLR socket, one BNC socket and one RCA socket - BNC and RCA sockets are driven by the same driver chip
• Eight LEDs for sampling frequency display and power status
• Switch allows to select the sampling frequency for DSD to PCM conversion (176.4 or 88.2 kHz)
• Switch selects the word-length for DSD to PCM conversion (24 or 16-bit)
• Power switch handles the power on/off for the external power supply input
• Back panel includes power inlet for the external power supply, the USB connector, the three output connectors (BNC, RCA, XLR)
• Silver anodized aluminum frame
