Opis

  • Two discrete mic/line/hi-z preamps 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

 

  • Two instances of ‘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

 

  • Two discrete headphone mixers with independant CH 1, CH 2, and Aux Input level controls
    • Monitor the Camden preamps directly with headphones during mic placement to find the sweet spot of the instrument/source
    • Create zero-latency artist mixes by combining the Camden preamps with external playback from Aux Input 14/” jacks on Camden EC2’s rear panel
    • Use the reference grade headphone amps for critical listening by sending stereo mixes from the interface into the Aux input and monitoring directly using Camden EC2’s headphone outputs
    • ‘Stereo’ switch to pan CH1 & CH2 left and right in each headphone mix for true stereo monitoring

 

  • Two reference-quality, high-powered headphone amplifiers
    • 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 outputs and impedance balanced ¼” jack outputs for maximum connectivity into audio interfaces and other downstream equipment

 

  • Dedicated Impedance balanced 1/4″ Jack Link outputs for true instrument DI functionality and splitting instrument inputs to balanced or unbalanced amplifiers and effects

 

  • C.A.S.T. OUT port for connecting Camden EC2 into 500R8/500ADAT
    • Transmit Camden EC2’s preamps 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 EC2’s headphone mixers
    • All managed and distributed via a single shielded Cat 5e, Cat 6, or Cat 7 cable

 

  • C.A.S.T. IN port for connecting N22/N22H Cat 5 snakes to relocate Camden EC2 I/O elsewhere in the studio
    • Receive 2 mic/line signals from N22/N22H directly into the preamp inputs of Camden EC2
    • Transmit Camden EC2’s Aux 1 headphone mix into N22/N22H for direct monitoring by the musician
    • 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
