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 Saturation 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
