Hey everyone,

Cranborne Audio have some exciting news to announce today. We've just published our final specifications for the Camden 500 preamp and signal processor for 500 series.

We knew it would be good, but maybe not THIS good.

Here are the specs:

We’ve actually ended up with (probably) the cleanest, most transparent 500 series mic preamp on the market; and we’re going to sell it for a price that everyone can afford - $349 US Retail / £299 RRP IncVat.

Thanks to its Mojo circuit, it’s also a lot more than just a clean preamp. Mojo is a 100% analogue saturation circuit that can be dialled-in to be one of the most saturated and ‘transformer-like’ preamps in your arsenal. Or Mojo can be bypassed completely to reveal the cleanest, frequency/phase-linear preamp you've ever heard.

Some key highlights in the spec are:

<0.0004%, 1kHz, 35dB gain, 24dBu out - (Millennia HV-35 quotes 0.003% THD+N at the same conditions....)

Equivalent Input Noise (EIN):
<-129.5dBu, 150 ohm source, unweighted - (that’s pretty much the theoretical limits of EIN).
<-131dBu, 150 ohm source, A-weighted
<-135.5dBu, Inputs common, unweighted

Frequency Response:
±0.25dB, <5 Hz to >200 kHz, 35dB gain
<±1dB, <5 Hz to >200 kHz, max gain - (most preamps have dramatic frequency roll-off at max gain)

Phase Shift:
<2.25°, 40dB gain, 20Hz to 20kHz
<4°, Max gain, 20Hz to 20kHz - (4° at max gain is pretty much unprecedented, it’s not uncommon to see 10-30° of phase shift on the very best preamps at max gain)

Intermodulation Distortion:
<0.0008%, 50Hz and 7kHz, 35dB gain, 20dBu out
<0.0006%, 50Hz and 7kHz, 35dB gain, 15dBu out

This is just one of a series of announcements we will be making in the next few weeks including the feature set, performance, and pricing of 500R8 and 500ADAT! - the wait is almost over!

We'll also be making our new website live product photography, specs, manuals, graphs, and all sorts...

Thank you to everyone who has shown their interest so far! - we think you guys will like what you see! The wait is almost over!
