Cranborne Audio Camden 500

• Fully-discrete, transformerless design featuring our custom ‘Camden’ preamp topology designed by our Director of Engineering – Edward Holmes
• Optimised for and fully-compliant with the 500-series format
  • Camden 500 is not a 19” unit shoe-horned into a 500-series module, it has been designed from the ground-up to perform under the low-voltage power rails and supply current limitations of the 500-series format whilst delivering groundbreaking performance
• Performs at the near-theoretical limits of noise, distortion, and phase/frequency linearity at all gain settings
  • EIN: <-129.5dBu, 150 ohm source, unweighted, <-135.5dBu, Inputs common, unweighted
  • THD+N: <0.0004%, 1kHz, 35dB gain, 24dBu out
  • Intermodulation Distortion: <0.0008%, 50Hz and 7kHz, 35dB gain, 20dBu out
  • Phase Shift: <2.25°, 40dB gain, 20Hz to 20kHz, <4°, Max gain, 20Hz to 20kHz
  • Freq. Response: <±1dB, <5 Hz to >200 kHz, all gain settings
  • CMRR: >70dB, typ >85dB, 35dB Gain, 10-20kHz, 100mV Common mode
• Optimised input Impedance and input headroom for Mic, Line, and Hi-z sources
  • Mic Preamp, Instrument Di, and – thanks to Mojo – line-level analogue saturator
• Custom ‘Mojo’ analogue saturation circuit with variable control, true bypass, and 2 discrete styles – Thump and Cream
  • Reamp tracks from your DAW through Mojo to apply analogue saturation to your stems, VST, and stereo mixes
  • Thump excites low-end content by boosting lower odd/even harmonics from a range of 160Hz to 20Hz and below
  • Cream boosts odd/even harmonics whilst also reducing the amplitude of the fundamental frequencies and applying typical transformer-style transient taming
• Gold Flashing on backplane contacts for increased conductivity and durability
• Designed & Engineered in the United Kingdom
