R3 Tech Specs

tech specsThe R3 is a powerful stereo router which allows you to insert and process analogue outboard in a record chain. For the numerically minded, here are the R3's technical specifications:


Analogue Trimmer Amplifier

  • Technology: Precision, passive balanced attenuator with high current output buffers
  • Noise floor: -105dBu, 20Hz to 20KHz, unity gain
  • Maximum input level: +33dBu
  • Maximum output level: +27dBu balanced
  • S/N >132dBA (~4x quieter than any commercially available audio DAC)
  • THD -105dB at 1KHz, +20dBu signal, unity gain, 20Hz -20KHz filter
  • Input impedance: 3K3 ohms
  • Output impedance: 47 ohms balanced outputs
  • Coupling: there is a single bypass-able AC blocking cap for safety, DC on output is less than 0.5mV

Analogue Routing - monitor selector and insert box

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

Optional 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: 2RU to 5RU, option specific
  • Control Panels: 173mm (7")high, 210mm to 420mm (8" -17") wide, option specific. Fits into 4RU space.
  • Weight: 12Kg to 25K, 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
