tech specsThe C30 is a powerful surround monitor controller, which works with both stereo and surround analogue sources. For the numerically minded, here are the C30's technical specifications:

 
Analogue Monitor Controller

  • Technology: Precision, passive balanced attenuator with high current output buffers. Bypass-able high impedance input buffers
  • Noise floor: -105dBu, 20Hz to 20KHz, unity gain
  • Maximum input level: +33dBu, without the optional high impedance buffers, +27dBu with them in place
  • Maximum output level: +27dBu balanced
  • S/N >135dBA (~4x quieter than any commercially available audio DAC)
  • THD -108dB at 1KHz, +20dBu signal, unity gain, 20Hz -20KHz filter
  • Input impedance: 3K ohms without input buffer, 40K ohms with input buffer
  • Output impedance: 47 ohms balanced outputs - unbalanced outputs available via the Headphone amplifier (see below)
  • Coupling: there is a single bypass-able AC blocking cap for monitor safety, DC on output is less than 0.5mV

Analogue Headphone Amplifier

  • Technology: Hybrid op-amp and discrete power transistors
  • Noise floor: -102dBu, 20Hz to 20KHz, unity gain
  • Maximum output level: +21dBu unbalanced
  • S/N >126dBA (more than any commercially available audio DAC)
  • THD -102dB at 1KHz, +20dBu signal, unity gain, 20Hz -20KHz filter, 600R load.
  • Maximum current output: 200mA peak, 150mA RMS
  • Maximum output power: ~1.5W into 120 ohms load.
  • Output impedance: 0.2 ohms.
  • Unbalancer: 3 stereo pairs of ground servoed amps are available to interface the console to unbalanced outputs.

Analogue Routing - monitor and transfer selector

  • Technology: Completely passive, balanced relay switched system.
  • Noise: not measurable, theoretically about -170dBu.
  • THD: not measurable.

DA and AD Converters

  • Technology: SRC isolated converters working off their own internal clocks, balanced analogue stages, minimal configuration
  • 0dBFs: fixed at +18dBu
  • S/N: -120dBA A weighted. -117dBu 20Hz-20KHz
  • THD: -105dB, 20Hz- 20KHz 0.1dB below clipping
  • External ADC wordclock: 44.1 - 196KHz
  • I/O levels: AES or SPDIF I/O, link selectable
  • Conversion jitter: "Jitter free" IO - jitter doesn't affect THD performance

Physical

  • Remote racks:1RU to 2RU, option specific
  • Control Panels: 173mm (7")high, 210mm to 315mm (8" -12") wide, option specific. Fits into 4RU space.
  • Weight: 12Kg to 15K, option specific.
  • Distance from racks to control panels: 6M (18ft) standard, up to 200M (600ft) with optional local PSU
  • Power consumption: 60W to 130W, options specific.
  • Power Supply: 12V via supplied external universal input (80V-250V AC) SMPS
