Cranborne Camden EC1 The Ultimate Performer’s Front End

Camden EC1 is an award-winning Camden preamp with Mojo analogue saturation, and a reference-quality headphone amplifier with a discrete line mixer built-in to a desktop-friendly, half-rack chassis.

Award-winning Preamp Performance Connect Camden EC1 to your audio interface and experience the award-winning sound of the Camden preamp design. Providing up to 68.5dB of pristine, clean gain, Camden EC1 is the perfect preamp to pair with low-gain dynamic microphones and ribbon mics. Powerful Headphone Monitoring Featuring a reference-grade, high-powered headphone amp with a dedicated line mixer, Camden EC1 gives you TRUE, zero latency, mastering-quality monitoring of your preamp that is effortlessly mixed with playback from your DAW. 3 World-Class Preamps In 1

Thanks to its custom 'Mojo' harmonic saturation control, Camden EC1 offers 3 flavours of preamp tone that can be dialled to taste.

With Mojo bypassed, you can experience Camden EC1's award-winning transparency for capturing mic, line, and instruments with elite-level detail and non-existent noise/distortion.

• Discrete mic/line/hi-z preamp featuring the award-winning ‘Camden’ topology from the Camden 500 Preamp and Signal Processor for 500 series
• Audio performance 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: <0.00025% (1kHz, 35dB gain, +24dBu out)
  • Intermodulation Distortion: <0.0006% (50Hz and 7kHz, 35dB gain, +20dBu out)
  • Phase Shift: <2.75° (20Hz to 20kHz, 40dB gain), <6° (20Hz to 20kHz, Max Gain)
  • Freq. Response: ±0.7dB (<1 Hz to >1000 kHz, 35dB gain), ±1dB (<5 Hz to >200 kHz, Max Gain)
•  Unique 48v status LED
  • 48v LED Lights Orange to indicate voltage charging or dissipating to prevent damage to ribbon microphones and to ensure voltage is fully charged before use
  • 48v LED lights RED when voltage is fully charged and ready to use
• ‘Mojo’ analogue saturation circuits with variable control, true bypass, and 2 discrete styles - Thump and Cream

• • 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

• Discrete headphone mixers with independant CH 1, Ext Input, and Aux Input level controls
  • Monitor the Camden preamp directly with headphones during mic placement to find the sweet spot of the instrument/source
  • Create zero-latency artist mixes by combining the Camden preamp with external playback from Aux Input 1/4” jacks on Camden EC1’s rear panel
  • Use the reference grade headphone amplifier for critical listening by sending stereo mixes from the interface into the Aux input and monitoring directly using Camden EC1’s headphone output

• Reference-quality, high-powered headphone amplifier
  • Freq. Response: <±1dB, <1 Hz to >100 kHz
  • Output Impedance: 0.33 Ohms
  • THD: 0.0003%, 1kHz
  • Output Wattage: 2x250mW @ 600 Ohm, 2x450mW @ 220 Ohm, 2x250mW @ 100 Ohm

• Balanced XLR output and impedance balanced 1/4” jack outputs for maximum connectivity into audio interfaces and other downstream equipment
  • -10dB PAD to attenuate preamp output for lowheadroom audio interfaces

• Dedicated Impedance balanced 1/4" jack Link output for true instrument DI functionality and splitting instrument inputs to balanced or unbalanced amplifiers and effects

• C.A.S.T. OUT port for connecting into 500R8/500ADAT
  • Transmit Camden EC1’s preamp and Ext Input directly into 500R8 and 500ADAT’s 500 series modules inputs for recording/processing
  • Receive a stereo mix generated from 500R8/500ADAT and monitor using Camden EC1’s headphone mixer
  • All managed and distributed via a single shielded Cat 5e, Cat 6, or Cat 7 cable

• External high-current 24v, 1.25a power supply with latching connector
