The DAC202 is a reference class Firewire D/A Converter with a IR remote control for volume control, absolute phase and input source selection.

Features of the DAC202:

  • Available in silver or black finish
  • Digital Inputs: AES/EBU or S/PDIF on 1 XLR, 1 RCA, 1 Toslink, Firewire
  • Digital Outputs: AES/EBU on 1 XLR, 1 RCA, Firewire
  • Main Analog Output: 2 stereo analog outputs, one on XLR one on RCA
  • Headphone output on 1/4" Jack
  • Level control main output: 4 coarse settings via relays (analog domain), fine setting via rotary encoder (digital domain). Level control can be defeated for the main output.
  • Level control headphone output:  4 coarse settings via relays (analog domain, independent from the settings in the main output), fine setting via rotary encoder (digital domain).
  • Wordsync input on BNC connector
  • Wordsync output on BNC connector

Frontpanel controls:

  • LCD display for display of sampling rate, input source, audio level, absolute phase, upsampling filter type, various menu items
  • Rotary encoder with push switch
  • IR receiver
  • Standby LED
  • Headphone Jack socket

Special features:

  • Transparency check (allows to check the bit transparency of a playback chain)
  • Setting of the coarse output levels (analog domain), separate for the main output and the headphone output
  • Dual / single wire selection for 176.4 / 192 kHz sampling rate
  • "Insert Mode" allows to loop in a external digital audio device (e.g. a equalizer) via the AES/EBU I/O on the XLR connectors
  • Sampling rate setting on the WSYNC I/O connectors in dual wire mode
  • Display brightness

IR Remote control switches:

  • power on/off
  • volume up
  • volume down
  • input sources (4 switches for Firewire, XLR, RCA. Toslink)
  • DAC upsampling filter type
  • mute
  • absolute phase

Sampling rates: 44.1 up to 192 khz / 24 Bits

The DAC202 also has a new D/A converter and new analog output stages

compared to former D/A Converter models. The D/A converter uses two converters per channel to gain in signal to noise ratio.



MUSIC HALL

DAC 25.2




Today an increasing number of music lovers are buying, storing, and listening to music through their computer, media server, or personal music player (iPod). Many are also digitally distributing their music using a Sonos, Squeezebox, or one of a host of digital music distribution systems available on the market. This is a great way to explore and appreciate music but generally it’s done at the expense of sound quality. Until now, music lovers have been forced to rely on the inferior digital-to-analog converters (DACs) and sounds cards contained in those devices, and as a result, their musical enjoyment has dramatically suffered. Music Hall designed the DAC25.2 to directly address this problem and to significantly improve the sound quality of the music played on these systems.

By uniting a state-of-the-art digital-to-analog converter with a tube output we produce the clarity and precision of a 24bit DAC with the warm rich open sound people love of tubes. The DAC25.2 has 4 digital inputs which can accept any coax (s/pdif), optical, XLR, or USB digital input from an iPod transport, computer, media server, Sonos, Squeezebox, CD/DVD in stereo transport, or Music Hall’s CD25.2 compact disc player, and it will output two channel stereo analog.

The DAC25.2 features the latest Texas Instruments (formerly Burr-Brown) PCM1796 24bit, 192kHz, advanced segment, stereo audio digital-to-analog converter. This processor features 123dB dynamic range, an 8 x oversampling digital filter, and just 0.0005% THD. The DAC25.2 upsamples to either 96kHz or 192kHz, which is user selectable on the front panel. To achieve the best sound, Music Hall uses an advanced asynchronous reclocking and anti-jitter control system upstream of the PCM1796 DAC. This system uses the Philips 74HC574 in conjunction with the Ti SRC4192 Asynchronous Sample Rate Converter, whose master clock is a high precision active crystal oscillator. The DAC25.2 also features a large, high current oversize power supply. A headphone output is provided for convenient personal listening.
