  • Master Clock Generator
  • Low Jitter
  • Word Clock Input On BNC
  • World Clock Output On BNC
  • DARS (digital audio reference signal) Input On XLR (also locks onto AES3)
  • Selectable Clock Frequency

Master Clock Generator
The CLK GEN module provides clock reference signal to other modules in slots to the right. This master clock is available externally via a front panel BNC output.

Low Jitter
The high speed data bus provides very low jitter. Two devices are used for exceptional jitter specifications at 48kHz and another device for 44.1 kHz.

Word Clock Input On BNC
The CLK GEN can sync to external references via a front panel word clock input.

World Clock Output On BNC
The CLK GEN can act as master clock to external devices via a front panel BNC output.

DARS (digital audio reference signal) Input On XLR (also locks onto AES3)

Selectable Clock Frequency
A front panel push button scrolls through the following clock frequencies: 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz 

OPERATIONAL MODES

MASTER
The digital output frequency is set by the user and no lock will occur to any clock reference even if it is available.

AUTO SYNC
The output frequency will follow the reference input. If no reference is available then the output frequency is set by the user.

AUTO SYNC FOLLOW
Will follow external reference if detected. If this reference is lost, then the output frequency will continue at the closest frequency to the input before it was lost.

The DC-314 CLK GEN remembers its operational mode even after power resets.

  • A highly specified digital converter system for high audio quality and reliability
  • Very low distortion figures of less than 0.001%
  • Clock converters with jitter figures of -0.7 parts per million (48kHz)
  • 24 bit 48kHz
  • Sample rate from 32-192 kHz
  • Low noise Wolfson chipsets
Digital conversion, clock generation, and distribution of digital signals are all standard requirements within a broadcast facility or outside broadcast vehicle. What the DC-314 system offers are these functions, in the most effective combination that you need now, whilst allowing simple upgrading as situations change in the future.

Glensound have also developed a system of a common backplane that makes the 3u version very flexible, allowing multiple clock frequencies within the same frame. Multiple conversions can therefore be simply managed without the need for additional hardware.

With the flexible option of 3 different base units, 6 card options, front or rear cabling, and redundant power supply, the DC-314 system from Glensound is a powerful digital conversion solution. 

 

THE BACKPLANE
The development of the DC-314 digital converter started with the backplane. The card connections have an 'in' and an 'out' connector. After data and audio is received and used, if necessary, it is passed to the next card on the right.

Left Hand Priority
The backplane of the system first uses the leftmost card. The clock from this card is passed to the card to its right. This may be the clock from an AES input, or a new clock from the Clock Generator card. All subsequent cards to the right will operate at this frequency. When the backplane finds another Clock Generator card, it can set a new clock frequency to all further cards to the right without effecting the cards to the left. In this way, multiple frequencies can be utilised within the same system. There is no limit to this, and the high speed data required for digital clocks is maintained throughout.

The Control Bus
The system has an I2C control bus integrated into the backplane. This gives the DC-314 the ability to control and integrate all connected modules.

The control bus passes information that allows remote analysis and control. A card with an integrated web browser will be available in the future for this purpose.

Plug And Play
All audio cards will plug and play while the system is active with no audio side effects - unless you remove a clock generator that a digital output is relying on of course!

Future Development
The design of the system lends itself to simple customisation: analogue distribution, line ident, two channel mixer. Whatever the project, custom modules can be integrated with the DC-314.
