Weiss DAC 501/502


The DAC501 / DAC502 are Weiss' newest state of the art D/A Converters with an unprecedented level of sophistication and versatily.

With the DAC50x Weiss are creating a new paradigm for what used to be a black box device. A typical D/A Converter is a "set and forget" device. Not so with the DAC50x. It adds a number of interesting signal processing features and sports a variety of digital inputs. Balanced, unbalanced and headphone outputs are provided.

Weiss Engineering has a 30 year history in D/A Converter design. In that time span they have learned a thing or two about converter design. The DAC50x is the essence of the Weiss experiences.

The DAC501 has a similar size to the DAC202 unit. The DAC502 version is a larger size unit, similar to their MAN301 unit. The features of the DAC502 are the same as the ones of the DAC501.

A short overview of the DAC50x's features. 

Inputs (5 in total)

  • AES/EBU or S/PDIF via XLR, Toslink and RCA sockets

  • UPnP / DLNA via Ethernet

  • USB

  • Accepted formats: PCM 44.1kHz up to 384 kHz, DSD 64x / 128x
    Future formats can be accommodated for via software updates

Outputs

  • Line out unbalanced on RCA connector

  • Line out balanced on XLR connector

  • Headphone out on 1/4" Jack

Analogue
  • One of the latest 32 bit D/A Converter chips is used

  • Discrete output stages for both line and headphone outputs

    Signal Processing

    The DSP algorithms can be different depending on which output is selected (line or headphone). Some DSP algorithms have to work differently if they are used for headphones in comparison to speakers.The DAC50x has a digital signal processing chip built in (DSP). The following DSP algorithms are currently implemented or implemented soon:

    • Room Equalizer - to suppress room modes for a decent bass reproduction.

    • Creative Equalizer - A tone control with low boost/cut, high boost/cut and mid boost/cut. Very useful to correct those recordings which do not quite fit your taste.

    • De-Essing - The automatic removal of overly bright sibilances from human voices. The sibilance effect can be more or less pronounced depending on your speakers or room acoustics.

    • Constant Volume - Adjusts the audio volume (loudness) to a constant value across all tracks played. Useful for "party mode" when the volume control should stay untouched.

    • Vinyl Emulation - Get that special sonic character of a record player based playback chain.

    • Crosstalk Cancelling (XTC) - For the playback of dummy head recordings or live recordings via speakers for an incredible live sensation. (For speaker based playback only.)

    • Out Of Head Localization algorithm - Tries to get the music "out of your head" when listening via headphones. The goal is to achieve a similar listening sensation as one gets when listening via speakers. (For headphone based playback only.)

    Converters
    • Two of the latest 32 bit D/A Converter chips are used. Two D/A conversion channels are used per audio channel, resulting in exceptional performance specifications.
    Controls
    • The DAC50x is operated via the rotary encoder control on the faceplate, the touch sensitive colour LCD display or the IR remote control. Some additional settings can be done via a web interface from any computer.

    Mechanics
    • The DAC501 has a similar size to the DAC202 unit. The DAC502 version is a larger size unit, similar to their MAN301 unit. The features of the DAC502 are the same as the ones of the DAC501.
