CAMBRIDGE

Our History
As we’re heading toward our 50th birthday next year, we’ve had a look back at the history of Cambridge Audio.
Our History and Heritage
We’re so dedicated to putting sound first that in our time we’ve created many unique technologies that have been at the forefront of audio innovation to guarantee our products the purest sound.

Our first ever product, the P40 integrated amplifier went down in the history books as the first amplifier to use a toroidal transformer. This was a significant innovation and is now – because of its superior performance – a standard component inside virtually every hi-end amplifier produced by manufacturers since then.
The follow up to the P40 came only a couple of years later in 1970 with the P50. This was a much more powerful amplifier with a unique active volume control, useful for matching a variety of different input levels.
1971 saw our first foray into the world of loudspeakers with the R50 Transmission Line Speakers. These seven foot beasts used a ‘tapered labyrinth’ construction, dampened with lambs wool to reduce distortion. However, it did mean each speaker weighed over 44kg…

A new decade meant a new look and range, which was especially evident with the C75 pre amplifier and A75 power amplifier in 1984. They used high current output stages and a new, low distortion amplifier design called ‘segmented equalization’. End panels could be used to combine the C75 and A75 into a single unit. More innovation came a year later with the CD1, the world’s first 2-box CD player with the upper deck carrying the control, transport and power supply while the lower housed decoder and analogue filters. To this day it’s known as a landmark product in CD reproduction thanks to its unique design incorporating three DACs per channel and three power supply transformers.

In 1995 we launched our A1 integrated amplifier which was the first product to come out of the company since it was bought in 1994 by the present owners James Johnson-Flint and Julian Richer. From the start, they were committed to the idea that Cambridge Audio should continue to create ground-breaking, original & proprietary technologies and they did exactly that with the A1. It was a huge success and one of our best selling products ever.

By 1996 Cambridge Audio had a complete digital and analogue engineering team capable of designing and developing complete products in-house. One of the first products to benefit from this was the original DacMagic digital to analogue convertor launched in 1996 to almost universal acclaim and the distinction of being our first outright What HiFi? award winner.
Another first in 1999 was with our first step into the home cinema market with the V500 Dolby digital Decoder. Since then we’ve kept on top of the market with the release of DVD, AVRs and Blu-Ray players.

Our Technologies
The birth of the millennium also saw the birth of one of our most important product ranges, the Azur series in 2003. The Azur family began life with the 340A, 540A and 640A integrated amplifiers, along with the 340C, 540C, 640C CD players and the 640T DAM/FM tuner.
This led to our critically acclaimed Azur 840 series released in 2006, the first of our products to re-define what is meant by ‘affordable hi-fi’ whilst also enabling us to establish ourselves as serious players in the world of high-end audio. The Azur 840 series used two key technologies that we designed in-house and still use today:
Our patented Crossover Displacement (XD) amplification combines the performance of Class A with the efficiency of Class AB. At the time it helped the 840A to be selected as the 2007/2008 two-channel amplifier of the year at the prestigious EISA Awards.

We also developed Adaptive Time Filtering (ATF) up-sampling which up-samples any digital signal – such as CD’s 16bit 44.1Khz – to a 24bit, 384Khz signal which presents a much more accurate audio soundwave
2008 also saw the release of the new DacMagic which swiftly became the ‘go-to’ hi-fi upgrade setting the standard for stand-alone DACs. It came at the right time too, as from here on we’ve seen a DAC resurgence that’s still alive and kicking today.
Another proprietary technology we introduced to our products were the hybrid BMR (Balanced Mode Radiator) Drivers used first in our Minx Min10 and Min20 satellite speakers in 2010. BRM technology uses a single, flat panel to produce an ultra-wide range of frequencies, eliminating the need for a separate tweeter.

We still use the BMR Drivers today in many of our wireless speakers, loudspeakers and our 3rd generation Min12 and 22 satellite speakers. We applied them to our new Aero speaker range which won “What Hi-Fi? Sound and Vision’s Best Speaker Package of the Year” award in both 2013 and 2014. The Aeromax range followed suit using new BMR drivers, improved cabinets and upgraded crossovers.
2011 was another landmark year for Cambridge Audio with the introduction of the NP30, our first Network Music Player, and
