CA E2
The Camden Ec2 is a Two channel 19", 1u preamp featuring award-winning Camden preamps, Mojo analogue saturation circuits, and dual reference-quality headphone amplifiers with discrete line mixers.
Type: Preamps/Channel Strips
Ultra-Clean and Transparent Performance
Camden EC2’s preamps exhibit performance specifications that rival and exceed the most revered ‘transparent’ preamps on the market.
>With Vintage Mojo On Tap
With two discrete Mojo styles, Camden EC2 takes on the persona of vintage transformer-based preamps using its Thump Mojo or gooey tube-based preamps using its Cream Mojo.
Capture your audio sources with complete transparency; boost low-sensitivity microphones without adding noise; and capture instant transients without phase shifts that cause summing abnormalities.
Unlike transformer or valve-based preamps, Mojo’s saturation is completely variable allowing you to dial-in the amount of saturation you need for each source. Keep it at 3-4 for authentic preamp THD or crank it up to 11 for a more exaggerated effect.
