Timing is everything

The worlds most revolutionary
Master Clock

Big Ben, the worlds most revolutionary Master Clock, features Apogee’s legendary clocking technology and much more into one standalone unit. Supporting all sample rates and offering clocking technologies, “C777” and “Adaptive Loop Filtering” (ALF), Big Ben is the most stable, low jitter clock available. Big Ben will synchronize all digital equipment in the recording environment bringing clarity, depth and accuracy to recording and mixing that will be heard immediately.

Providing incredible flexibility with available formats of AES, S/PDIF, Optical, six (6) Word Clock outs and an expansion slot of the X-Video option card, Big Ben will synchronize any studio and provide format conversion simultaneously.

Features

  • AES, S/PDIF, Optical I/O – Word Clock/Video In – 6 Word Clock Outs
  • Optional X-Video expansion card to provide master
    video sync generator
  • Realtime format conversion between all digital formats
  • Direct Digital Synthesis (DDS) using Apogee´s C777 Clock
    Technology up to 192kHz
  • Adaptive Loop Filtering (ALF) to optimize clock performance
    and minimize jitter
  • Three stage Termination Sensing for each word clock output

Adaptive Loop Filtering (ALF)

ALF maximizes Big Ben’s clocking ability with an intelligent low pass filter. With the C777 creating all incoming signals into data (1’s and 0’s) Big Ben is able to dynamically compensate for excessive jitter and even improve already acceptable clock signals to levels unattainable until now. No matter what your input looks like, ALF can adapt and overcome all obstacles to create a stable, reliable, low jitter clock source.

Big Ben for live sound

Big Ben will make a big difference in the recording studio but can also bring serious improvement when mixing Front of House and Monitors for a live performance. Clock your favorite digital mixing console like the Yamaha PM5D, AVID VENUE, DiGiCo SD8 and others to Big Ben and hear your system gain clarity, depth and imaging. It’s truly as simple as connecting a single BNC cable. Also clock your CD-R recorders, digital reverb units and other digital devices along with your digital console for improved sound quality across your entire rig.
