Apogee Releases Big Ben

Rackmount master digital clock supports up to 192 kHz By Dave Nagel
Apogee Electronics has released a new device called Big Ben, a 1U rack-mount master digital clock targeted toward audio and video production studios. Big Ben is designed to provide a new level of clock source stability and jitter reduction for A/D and D/A conversion. It's available now, with a FireWire option set to ship in the third quarter.

Big Ben uses Apogee's C777 clock with Adaptive Loop Filtering technology to adjust incoming clock signals, synchronize them and generate one stable clock source. It also offers a fail-safe lock to external sources, an optional FireWire card for format conversion, termination sensing and a range of inputs and outputs, including six word clock outs. Inputs include:

  • Two AES-EBU on XLR 44.1k-192k single-wide and 88.2 kŠ192k double-wide
  • S/PDIF optical on TOS-LINK 44.1 kHz to 48 kHz
  • S/PDIF coaxial on RCA 44.1 kHz to 192 kHz
  • ADAT 44.1 kHz to 48 kHz
  • ADAT/SMUX II for 88.2 kHz to 96 kHz
  • ADAT/SMUX IV for 176.4 kHz to 192 kHz
  • Word Clock BNC 44.1 kHz to 192 kHz
  • Video
  • Optional FireWire.

Outputs include:

  • Two AES-EBU on XLR single or double wide 44.1 kHz to 192 kHz
  • S/PDIF coaxial 44.1 kHz to 192 kHz
  • S/PDIF optical on TOS-LINK 44.1 kHz to 48 kHz
  • Six BNC Word Clock 44.1 kHz to 192 kHz
  • ADAT
  • Optional Firewire.

The FireWire option is expected to be available in the third quarter with support for Mac OS X and Windows. (The hardware is otherwise platform-independent.) Pricing on the FireWire option has not yet been set. The current model without FireWire sells for $1,495. For more information, visit
