Multipurpose converter

firewire D/A converter and more

Dare we say the DAC2 is a Swiss army knife? It certainly is a Swiss multipurpose digital-to-analog and digital-to-digital format converter. Use it with a Firewire-equipped computer or other digital audio sources and convert the stream to pristine analog or digital outputs, depending on your needs.

Main Features

Weiss DAC2

INPUTS and outputs

There are three digital inputs on XLR, RCA, and TOSLINK (optical) connectors. In addition, a computer can be connected via a Firewire interface. The accepted sampling frequencies are 44.1, 48, 88.2, 96, 176.4, and 192 kHz. The front panel has buttons for input selection and display of the sampling frequency.

Digital outputs on XLR and RCA connectors are used to convert Firewire to AES/EBU and also for the insert point feature described below.

De-jittering and level control

The DICE Firewire interface chip in the DAC2 uses a dual PLL scheme for clock (re-)generation. This yields a very high jitter suppression down to subsonic frequencies.

The DAC2 uses THAT line driver chips with low output impedance and excellent distortion figures. Separate driver chips are employed for the XLR and the RCA outputs. The output level can be set in the analog domain in four coarse steps to accommodate for the subsequent amplifier. Fine tuning of the level can be done via the digital level control which is operated via the front panel keys.

optional interfaces

Options for the DAC2 include a USB/DSD interface that allows playing back DSD files via the DAC2. An ST-type glass fiber input is another option. For connecting this unit to Thunderbolt there is a Thunderbolt to Firewire adapter available from Apple at a low cost.
