Mechanics 
The INT204 is housed in a silver anodized aluminum frame.

Power Supply 
Two power sources are required for the INT204. One is the bus power fed via the USB connector, the other is an external power supply which is supplied with the INT204 unit. This scheme allows to have the input and output sections of the INT204 galvanically isolated.

Synchronization
The sampling frequency is generated with an internal generator in the INT204. This makes sure the transfer between computer and D/A Converter is low jitter. Digital Input A USB type B connector is used a connection to the computer.

Digital Outputs
There are one XLR socket, one BNC socket and one RCA socket. BNC and RCA sockets are driven by the same driver chip.

Front panel controls
There are eight LEDs for sampling frequency display and power status. A switch allows to select the sampling frequency when doing DSD to PCM conversion (176.4 or 88.2 kHz). Another switch selects the word-length when doing DSD to PCM conversion (24 or 16 Bit). A power switch handles the power on/off for the external power supply input.

Back panel elements from left to right
There is a power inlet for the external power supply, the USB connector, the three output connectors (BNC, RCA, XLR).

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).

Main Feature
You may own your favorite D/A Converter already. It may be not the latest and greatest, but you like its sound and its looks and features. So you don’t like the idea to get another DAC just to be able to connect the computer. This is where our interfaces come in (also see the INT202/INT203 interfaces described elsewhere). They allow to connect any DAC to any computer. And this in a decent way, with the computer slaved to the internally generated clock and with absolute bit transparency.
