Cranborne Audio Camden EC1 Preamp

Perfect For Musicians, Engineers, Podcasters, Voice Over Artists

Musicians, develop your own signature sound using Mojo analogue saturation and take it on the road or from studio to studio with you. Record natural and forgiving-feeling instrument DI's that perfectly capture the character of your pickups and instrument. Split the Hi-Z signal using the Link Output to record both the DI and a processed amp'd signal, perfect for re-amping workflows.

Engineers, critique your mix or master using a true, reference-grade headphone amp with clean power, and enough volume to make your headphones shine. Offer TRUE zero-latency mixes to your clients that can be controlled using 2 simple controls directly on the front panel for Preamp, Aux in/DAW level. Comprehensive connectivity including balanced XLR and 1/4" impedance balanced preamp outputs and a 10dB pad to prevent clipping your converters.

Podcasters, apply 68.5dB of gain to low-sensitivity microphones (Shure SM7b. EV RE20) without adding noise or colouration. Monitor your own voice in ZERO latency as well as your Program Output using the reference-grade headphone amp built-in to its front panel.

Voice Over Artists, monitor your vocal channel directly using headphones connected to the preamp itself. Use Mojo to apply different characters to your voice, use Thump for intimacy or use Cream excitement. Record using the Mojo settings for a streamlined workflow.

Priced to be your first preamp but performs to be the only preamp you will ever need. World-class technical excellence at home in any professional studio around, delivered to your studio for less than you may think.


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.

It features a modern pristine or vintage saturated preamp performance combined with a comprehensive feature set, the Camden EC1 is one of the most versatile preamps on the market and perfectly at home in any application you can throw at it.

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.

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.

Capture your mic, line, and instruments with complete transparency, boost low-sensitivity dynamic microphones without adding noise and capture instant peaks without phase shifts that make mixing difficult.

At the turn of a dial, the clean, Camden preamp takes on the persona of vintage transformer or valve-based preamps using its Mojo analogue saturation control and 'thump' and 'Cream' styles.


Immersive Headphone Amp with Zero Latency Mixing

The reference-grade headphone amplifier built-in to Camden EC1 is as impressive as its Preamp, but the way it has been tightly integrated with the preamp makes it even more special.

Monitor the Camden preamp in true, zero-latency using headphones connected directly to its front panel and mix it in with external DAW playback using the stereo 1/4" Aux Input jacks on Camden EC1’s rear panel.

With the same reference-grade design developed for the 500R8 audio interface, Camden EC1's headphone amps deliver up to 1.2 watts of clean power per ear and a flat frequency response from 5Hz to 70kHz, perfect for powering any set of headphones with clean power.


A Preamp That Goes with You, Portability and Power Timeless Analogue

Housed in a half-rack, desktop format, you can take Camden EC1 with you, studio to studio, or on stage. Dial-in your sonic signature and control your own headphone monitoring consistent and pristine.

Devoid of software updates and USB standards, the Camden EC1 is with you for the long haul. Even when you upgrade your surrounding studio, Camden EC1 will always provide your tonal benchmark.
