CD50 Signature

The Signature Series CD players have benefited from many innovations, whether in terms of power supplies or audio and conversion stages. In addition, all of these devices can now accommodate a 24 bits/192 kHz DAC board relying on the player’s internal converter. The USB input is asynchronous.

  • 4 mm brushed aluminium front.
  • 6 regulated power supplies.
  • Separate 46 VA transformer for the audio stages.
  • BURR-BROWN PCM1793 converter:
              – 24 bits/192 kHz.
              – Dynamic: 113 dB.
              – Signal/Noise ratio: 113 dB.
  • Original TEAC central CD mechanics.
  • Pure audio CD player compatible: CD, CD-R, CD-RW, MP3, WMA-AAC.
  • Linear power supply for digital stages with a specific 30 VA transformer.
  • Separate linear power supply for the audio stages.
  • Double-sided circuit boards with nickel/gold finish.
  • Low consumption OLED display.
  • Reading the CD-Text.
  • Class A biased discrete component differential audio output stages.
  • Optional 24 bits/192 kHz digital board for all signature series CD players.
  • ATOLL global remote control.

CD players from the Signature range can be optionally fitted with a card with three digital inputs:

  • 1 Coaxial input (S/PDIF – 24 bits/192 kHz).
  • 1 Optical input (S/PDIF – 24 bits/192 kHz).
  • 1 Synchronous USB-B input: 16 bits to 24 bits PCM stream up to 192 kHz asynchronously (USB interface: XMOS with a program specifically developed for ATOLL).


Important: using the USB input of the optional DAC card requires downloading a specific driver for Windows computers. This can be downloaded below. This driver is not necessary under MAC and Linux.

The remote control is supplied as standard on each model and allows remote control of all ATOLL products (Integrated, preamps, Tuner, DAC).
In addition, it has all the basic functions including programming, random play, repeat, etc.

The CD50 Signature is available in black or natural aluminium:

Black anodized brushed aluminum finish.
Silver anodized brushed aluminum finish.
