Product Information Cranborne Audio EC2
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.
Two Channel Preamp
Based on the award-winning Camden 500 Preamp and Signal Processor for the 500 series lunchbox format, Camden EC2 combines the sonic capabilities of one of the markets cleanest and most transparent preamps with the flexibility of a standalone, 1u, 19” chassis that can integrate into any recording setup with or without 500 series connectivity.
Dual Headphone Mixer
More than two preamps in a metal box, Camden EC2 features Two reference-quality headphone amplifiers with independant line mixers that allow for direct monitoring of both Camden preamps using headphones connected directly to Camden EC2’s front panel.
