Dual Channel Preamp And Instrument DI
Featuring a custom transformerless front-end topology with 68.5dB of gain, Camden EC2 achieves groundbreaking performance in noise, distortion, frequency response, and phase shift throughout all 12 gain positions. Each of EC2's preamp's feature tailored input impedance and headroom for Mic, Line, and Hi-Z sources using a dedicated 3-way input type switch on each channel.
Dual Headphone Mixer
Two reference-quality headphone amplifiers with discrete line mixers allow for direct monitoring of both Camden preamps using headphones connected directly to Camden EC2’s front panel.
Monitor the preamp during mic placement to find the sweet spot of a guitar cab, kick drum, or acoustic instrument; alternatively, configure them to create a zero-latency all analogue monitor mix combining the local Camden preamps with playback incoming from an external playback source via Camden EC2’s rear panel Aux Inputs.
Camden EC2 features two instances of one of the cleanest, most linear, and transparent preamps on the market. Our new ‘Camden’ preamp topology allows us to push the boundaries of Frequency response, phase shift, noise, and THD performance; and we have all the specs to back that up.
EIN: <-129.5dBu, 150 ohm source, unweighted
<-135.5dBu, Inputs common, unweighted
THD+N: <0.0004%, 1kHz, 35dB gain, 24dBu out
Phase Shift: <2.25°, 40dB gain, 20Hz to 20kHz
<4°, Max gain, 20Hz to 20kHz
Freq. Response: <±1dB, <5 Hz to >200 kHz, all gain settings
CMRR: >70dB, typ >85dB, 35dB Gain, 10-20kHz, 100mV Common mode

Numbers on a spec sheet is one thing, however those numbers can change drastically depending on the frequency measured and preamp gain. Camden 500's technical performance excels not only at key gain positions, but also when the gain control is increased to its maximum. Many preamps can boast excellent performance at one gain setting but that performance can often fall apart once the gain is increased. Camden 500 retains minimal phase shift, frequency roll-off, and THD at all gain positions enabling you to get the best results out of ribbon and low-output dynamic mics without fear of losing performance as the gain is increased.

Developed in conjunction with our immaculate Camden preamp topology, our Mojo analogue saturation circuit transforms Camden EC2 into a true vintage monster.
Mojo comprises of a brand-new type of saturation circuit featuring discrete second and third order harmonic generators with a series of filters that allow precise emulation of the saturation and frequency reinforcement behaviours of vintage equipment. Mojo goes to 11. Exaggerate it to to the point where destructive clipping would occur with transformer-based designs results in an even wider palette of saturation effects.
By manipulating these filters and harmonic generators; we can create two discrete Mojo styles; Thump and Cream. Both styles transform Camden 500 into the fattest, warmest, and most characterful preamp in your arsenal - all at the turn of a dial.
"...when I discovered the switched gain control I was smitten. But after listening to it and experimenting with the Mojo facility, I was completely sold.""There are far too many preamps to mention even in the 500 series alone, but few are this well built or designed, few sound this clean and quiet, and very few have this much sonic versatility."
"In short, this is how I’d design and build a quality preamp!"
"I was struck by how clean the gain was at very high gain settings. But the kit sounded especially ‘big’ when a bit of Thump was introduced. I was soon tempted to crank the MOJO full up for a big warm Bonham-like sound, and we were rocking."
"...If you want a top class flexible preamp and enhancer you’d be hard-pressed to find a better alternative at any price"
"The 1.5 Megohms Hi-Z input seemed to have a touch more natural openness than rival preamps, and the integrity of the signal is unquestionable"
"The designers set out to emulate the effects of valves and transformers, and what they have achieved is truly remarkable — it would be easy to believe that Cream is a flavour of valve ‘overdrive’. "
"First thoughts: this is a very quiet unit and it’s somehow brought more top end out in the vocal. We A/B it with Jack’s lead vocal (recorded 5047 direct into the Babyface Pro, no Camden), and realise it’s also added warmth to the sound. Impressive. But I get the feeling we’re only scratching the surface."
"...we decide to turn it up to 11 [mojo], just to see what it can do. And my word, what a difference. On playback, with Mojo at absolute max, there is suddenly this smoothness and thickness that we haven’t yet experienced in The Hub - could this be ‘analogue warmth’, perhaps?!"
