Cranborne Audio Camden EC2
Congratulations on your purchase of Camden EC2 and thank you for selecting Cranborne
Audio to be a part of your music creation process.
Camden EC2 is an evolution of our Multi Award-Winning Camden 500 Preamp technology
developed into a 19”, rackmount format. From the beginning, we promised ourselves that
Camden EC2 would be more than just two Camden 500’s in a box. We set out to analyse,
critique, and improve every last detail of Camden EC2’s preamp design whilst packing it into a
complete recording and playback solution that would add much more functionality to any
studio with advanced, local monitoring and our C.A.S.T. cable management system.
The Camden preamps themselves are capable of being the most delicate and natural preamps
you’ve ever heard but at the turn of a dial, can transform into the fattest, warmest, and the
most character of any preamp in your arsenal. To partner the preamps, we added two discrete
line mixers with reference-grade headphone amplifiers that allow you to monitor the local
preamps directly during mic placement or blend live sources with pre-recorded sources during
tracking.

Package Contents
So now your Camden EC2 is out of it’s packaging, you’re probably itching to get it powered on
and making music! But before you get started, please read the sections below that will help
guide you through the process of getting Camden EC2 setup, plugged in, and ready-to-record
as quickly as possible!
The following items can be found in the packaging alongside Camden EC2:
- External power adapter
- IEC cable
- Allen key (2mm)
- Quickstart Guide
Rack-Ear Orientations
There’s more to Camden EC2’s rack ears than meets the eye. Camden EC2’s rack ears can be
repositioned in 2 ways to suit particular applications and offer greater protection during
transport.
Standard (Default) - Standard rack ear configuration where the rack ears are mounted
flush to the front panel of Camden EC2.
Recessed - Protective rack ear configuration where the rack ears are brought forward
allowing Camden EC2 to sit backwards into the rack to protect front panel controls
during travelling and location recording.
Depending on your desired use case, you will need to remove the 3 screws securing each rack
ear using the supplied 2mm allen key, realign the rack ears with the correct set of holes, and fix
them firmly back into place.

Power Supply
Camden EC2 is powered via an external 24v 1A DC switch-mode power supply that supports
any global operating voltage from 100 to 240v.
Switch mode power supplies can exhibit switching noise during operation, but Camden EC2
features linear regulation on the DC inlet to ensure that power noise and intermodulation
distortion doesn't find itself on the audio rails.
Camden EC2’s Power delivery is made via a latching 4-pin connector that is designed to
provide a secure connection to the chassis with protection against accidental removal.
Note:
Please only use the supplied power supply with Camden EC2. Damage caused
using an improper PSU with incorrect polarity or voltage is not covered under
warranty.
Connecting Power
Align the metal pins and plastic locator of the plug with Camden EC2’s Power Inlet [R11]. Once
located, push the connector firmly into the socket whilst holding the plug’s outer housing and
not the cable itself.
Disconnecting Power
Grip the body of the plug firmly and pull the body of the connector back from the Power Inlet
[R11]. The plug’s outer casing will pull back and release the safety latch to allow the plug to be
pulled out of the socket.
Note:
Excessive strain or a sudden tug/shock to the power cable could cause damage to
the cable strain relief as well as the hardware contact points associated with the
power input and power supply.
