- Page 3 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.

Page 8: Package Contents
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... -
Page 9: Power Supply
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. -
Page 10: Powering Procedures
Camden EC2. Press and hold the Power Switch for approximately 3 seconds. The power icon will deluminate and you will hear the soft ‘clicking’ of the relays indicating that Camden EC2 has been safely powered off. Note:... -
Page 11: Auto Power
Auto Power If Camden EC2 is situated in a rack full of other outboard equipment and preamps, it can be configured to automatically power on/off when power is switched on from a central location from inside the rack or a power conditioner when power is detected at its Power Inlet [R11]. -
Page 12: Hardware Setup: Audio Interface
Ensure that the inputs on the Audio Interface can accept balanced, line level signals at +4dBu or higher reference level for best performance. 3) Power On Camden EC2 using a brief tap of the Power Switch [F17]. Then power on your Audio Interface. -
Page 13: Hardware Setup: Using C.a.s
N22 for further processing and recording. At the same time, audio connected to N22 is sent through C.A.S.T. and into Camden EC2’s Aux In/C.A.S.T. Level [F12]. Then the Aux 1 mix created on Camden EC2 is sent through C.A.S.T. and onwards to the outputs of the connected N22/N22H. -
Page 14: Feature Overview
Celebrated thanks to its superior transparency and detail, as well as its Mojo variable harmonic saturation, the preamps inside Camden EC2 feature the same core design but with a few extra features that we have implemented to refine the preamp design further and make it even more effective in the modern studio environment. -
Page 15: Link Output [R3]
The Link Output [R3] is fed directly after the input stage of the preamp and is a dry, unaffected version of the instrument connected to Camden EC2’s hi-z/line input jack [F9]. The signal is fed before the preamp but it is buffered to maintain signal integrity. -
Page 16: Preamp Outputs
Preamp Outputs Each of Camden EC2’s preamps have 2 discrete outputs that can be used simultaneously for multi-routing scenarios and splitting capabilities in the studio or on stage. Balanced XLR Preamp Output [R7] - The XLR output is a fully balanced line output with a maximum output level of +24dBu. -
Page 17: Input Type Switch [F7]
35.5 46.5 57.5 68.5 Line Mode Gain Range In line mode, Camden EC2 engages an 8dB pad to enable a maximum input level of +26.5dBu and a gain range of 0dB to 60.5dB in 5.5dB steps. Position Gain (dB) 16.5 35.5... -
Page 18: Signal Indicator [F3]
Be careful when connecting line-level instruments (such as interfaces, keyboards) to Camden EC2 via XLR when 48v is engaged. Sending 48v through to the line-level outputs of instruments and playback devices can cause irreparable damage to their internal components and is not covered under warranty. -
Page 19: Status Indicator [F10]
The 48v Status LED [F10] is a Bicolour LED that displays the full 48v status of the preamp. Due to the design of Camden EC2’s preamps and its internal circuitry, the 48v can take a while to charge and discharge during use. As a safety feature and to prevent damage to your microphones, Camden EC2 displays the voltage status of the 48v using a 3rd, ‘Amber’, colour. -
Page 20: Polarity (Ø) Switch [F5]
The filter is set to achieve 3dB of attenuation at 80Hz and features a 12dB per octave slope. Camden EC2’s High Pass Filter has been tuned to achieve a smoother onset but more dramatic roll-off than standard filters resulting in a more natural-sounding low-frequency attenuation. -
Page 21: Headphone Amplifiers
Headphone bus, When the switch is on (Down), Ch1 and Ch2 are panned to the left and right sides of the headphone outputs respectively. This is ideal when Camden EC2 is being used in stereo mic’ing applications and you want to monitor the recording in true stereo through the headphone outputs built-in to the unit. -

⅛” connectors, you can connect a suitable adapter to convert the ⅛” jack to a larger ¼” jack. Splitters and headphone extenders can be used with Camden EC2 but please exercise caution when connecting them to Camden EC2 as improper connections can cause damage to the unit or degrade Camden EC2’s headphone performance. -
Page 23: Mojo
The Mojo Style Switch [F2] selects which Mojo circuit is currently active; Thump or Cream. Each Mojo style suits a variety of different instruments in different ways and for different effects. Camden EC2 User Manual -Page 23- ©2020 Cranborne Audio Ltd... -

Camden’s HPF to add low harmonics to the low-mid frequencies without adding extraneous low-end that could cause havoc during the mix phase. Camden EC2 User Manual -Page 24- ©2020 Cranborne Audio Ltd... -
Page 25: Cream
On distorted electric guitars, a generous amount of Cream will turn a dull recording into a speaker-busting, harmonically rich, mix-cutting masterpiece that stands shoulder to shoulder with any commercial recording. Camden EC2 User Manual -Page 25- ©2020 Cranborne Audio Ltd... -
Page 26: C.a.s.t
Each C.A.S.T. connection on a Cranborne Audio product features unique optimisation to ensure that the maximum signal integrity is transmitted over shielded Cat 5, Cat 6, and Cat 7 cables for distances of up to 100m(330ft) without high-end roll-off and with very low-crosstalk. -
Page 27: C.a.s.t. Wiring
48v Phantom Power will not pass through correctly. Any damage caused to the unit as a result of unsupported cabling is not covered under the Cranborne Audio warranty. C.A.S.T. Wiring Below is the wiring table that is used in both TTRR Output and RRTT Input paths of C.A.S.T. -
Page 28: C.a.s.t. Warnings
C.A.S.T. is designed to be a simple, plug and play solution for total cable management however there are a number of warnings that you should heed in order to prevent causing damage to your Cranborne Audio product or instrument/device connected to each end. Do NOT connect a C.A.S.T. - Page 29 C.A.S.T. Input [1] The C.A.S.T. Input [1] is used to connect Camden EC2 to the C.A.S.T. Output of another C.A.S.T.-enabled device. The single C.A.S.T. connector transports 4 channels of balanced analogue audio in both directions (2-In, 2-Out) and each path is labelled as either a ‘Receive’ path (for signals received by Camden EC2) or ‘Transmit’...

Bass Guitar. In this example, the Bass Guitar is connected directly to Preamp One using the front panel Hi-Z ¼” Jack input and the Link Output of channel one is connected directly to the input of a bass guitar amp. Preamp Two on Camden EC2 is then used to mic up the Bass Guitar amp. -
Page 31: Using N22H With Camden Ec2
Cat 5e, Cat 6, or Cat 7 cable. Note: A fully shielded connector is required in order to pass 48v correctly. 2. Connect Camden EC2’s C.A.S.T. Output to the C.A.S.T. Input on N22 using a shielded Cat 5e, Cat 6, or Cat 7 cable. - Page 32 This mix will then be sent through C.A.S.T. and to the Headphone output on N22H. With this setup, you are able to position Camden EC2 in your control room and use N22H in the live room/vocal booth as a remote stagebox for your artist to connect their microphones and headphones.

Page 33: Monitoring Two Playback Sources Using C.a.s
Once connected, you can use the Aux In/C.A.S.T. Level Control [F12] to adjust the level of both playback sources into the headphones connected to Camden EC2. Both sources are summed inside Camden EC2 and so the balance in their levels should be adjusted from the devices themselves. -
Page 34: Submixing Preamp Channels
The Aux 1 mixer of Camden EC2 can be used to mix together up to 6 sources from Camden EC2 to a single mono output on a true stereo output if required using a simple N22 passive breakout box. - Page 35 Camden EC2’s preamp channels 1 and 2 respectively to the outputs of the connected N22. With this setup, both of N22’s output will receive the same mix from Camden EC2’s Aux 1 Mixer for redundant recording. If you engage the Stereo Pan Switch [F15], Channel 1 and 2 on Camden EC2 will be sent to Outputs 1 and 2 on the connected N22.
