INT204 USB to AES/EBU interface
Your favorite DAC may not be the latest one on the market but you like the sound, the look and the features. So you don't want to buy another expensive DAC just to plug it into a computer.
This is where Weiss interfaces come in. The INT204 allows any DAC to be connected to a computer with a USB port. This is done, optimally, by slaved the computer's clock to the internally generated clock of the INT204.
The INT204 is a USB to AES/EBU (unidirectional) interface that also handles DSD to PCM conversion. DSD files played on the INT204 are converted to PCM at a selectable sample rate and bit rate. This turns your trusty D/A Converter into a DSD-capable DAC.
Additionally, the INT204 can function as a digital volume control device, controlled by an infrared remote unit.
Main features
Mechanics
The INT204 is housed in a silver anodized aluminum chassis.
Diet
The INT204 requires two power sources. One is the bus power supplied via the USB connector, the other is an external power supply that is supplied with the INT204. This scheme allows the input and output sections of the INT204 to be galvanically isolated.
Synchronization
The sampling rate is generated with an internal generator in the INT204. This ensures that the transfer between the computer and the D/A converter is low jitter.
Digital input
A USB Type-B connector is used to connect to the computer.
Digital outputs
There is an XLR jack, a BNC jack and an RCA jack. The BNC and RCA jacks are driven by the same driver chip.
Front Panel Controls
There are eight LEDs for displaying the sampling rate and power status. A switch allows you to select the sampling rate when converting from DSD to PCM (176.4 or 88.2 kHz). Another switch selects the string length when converting from DSD to PCM (24 or 16 Bit). A power switch manages the on/off for the external power input.
Rear panel elements from left to right
There is a power socket for external power supply, USB connector, three output connectors (BNC, RCA, XLR).
Software Features
The INT204 can perform DSD to PCM conversion at selectable sampling rates and string lengths (88.2 or 176.4 kHz and 16 or 24 Bit). The DSD input is in DoP format with a sampling rate of DSD64 (2.8224 MHz) or DSD128 (5.6448 MHz).
The supported PCM sampling rates are all standard rates between 44.1 kHz and 384 kHz. The sampling rate of 352.8 kHz is automatically converted to 176.4 kHz, and the sampling rate of 384 kHz is converted to 192 kHz, since AES/EBU or S/PDIF formats do not support sampling rates higher than 192 kHz.
Remote control
As an option, you can purchase an infrared remote control to control the audio volume in the digital domain.
