The all new io amplifier is designed with every music lover in mind. Simple to setup and operate, the io is designed to integrate seamlessly into any hi-fi system.

The compact size allows it to be used in a variety of systems and delivers a performance well beyond its price point. As you would expect, there is a high quality built in MM (moving magnet) phono stage, two line level inputs, a redesigned mini remote control handset and high quality headphone output that is cleverly integrated to deliver optimum performance without compromising the audio circuit.

All of these features combine to deliver a powerful, well balanced musical performance at an incredible price.

Product details

The io uses the same power amplifier and phono stage as its larger brother, the multi-award winning Brio. The io aims to deliver exceptional sound quality in a smaller and more cost effective package. The class A/B circuit shares its DNA with the rest of Rega’s amplifiers, and as usual, great care has been taken in component selection. Sanken output transistors and an Alps volume potentiometer and a linear power supply that enables an output of 30 watts per channel into 8 ohms.

Two line level inputs and a high quality moving magnet phono input are available as sources. There is a headphone output provided on the front of the unit for powering standard hi-fi headphones; this is driven from the power amplifier stage of the unit through relays to avoid signal degradation when headphones are inserted or the product is muted. A new remote handset is included as well.

What the press are saying.....

“The Rega Io is a great little amplifier, it packs a punch that you don’t get from the far more highly featured competition that exists on the market and delivers music that you just want to keep playing” - Jason Kennedy - Editor The Ear.

"From the first bars of music it is clear that the io is something rather special. With any budget amplifier there is always a sense of trepidation when waiting to see what the first notes will bring. While many are fun to listen to, they can be a little over exuberant at times. This never falls into this trap and, as a result, has the character of something you would expect to be rather more expensive.The smoothness and lack of sibilance, even in lesser recordings,is the real prize here, io has the feel of something much more expensive than its price tag suggests" - Adam Smith, Hi Fi Choice

The first Rega - A star is born

Roy was now working for Ford as a technical editor but spent most of his free time installing friend's hi-fi equipment and building loudspeakers to sell. He became a part time retailer and found he had to spend a ridiculous amount of time repairing new turntables before his conscience and common sense would allow him to sell them to others! Out of frustration and a strong feeling he could do better, the Planet turntable was born. Roy and a partner registered "Rega" (Tony RElph, Roy GAndy). In 1973 and for a couple of years, Roy stayed at Ford and made turntables in the evening, helped by his partners: mum (who agreed to help out for two weeks and stayed for fifteen years!) and a succession of lads. The first turntables were sold through Cosmocord in the UK and a year later under the Rega name in West Germany, Denmark and France.

Roy was now able to leave Ford; he collected a redundancy check and promptly blew it on a factory in Rochford. Soon after the partnership with Tony Relph split, Roy swapping his share of Rega. Terry Davies joined as Rega's financial administrator.

In 1975 the Planar 2 was developed and quickly took its place in the market as the finest budget turntable. In June 1977 HI-FI News and Record Review announced the Planar 3 saying "The complete unit is worth a look"! Rega's usual blaze of non-publicity.

By 1980 Rega employed thirteen staff, exported to twelve countries, had twenty UK dealers and there were those dreaded 'waiting lists', mainly by eager customers shop-hopping!

In 1980 Roy found an old mill (Park Street) in a residential area in Westcliff-on-Sea, Essex. The building had been deserted for twenty years and judging by the rot, seemed to have a millstream still running through it! Rega snapped it up for £30,000 and turned it into a compact but highly functional hi-fi factory, liberally painted bright green.

In 1983 after five years of dabbling and two years of intensive development, the RB300 and RB250 tonearms were produced. For ten years Rega had used Japanese and Danish manufactured arms on the turntables but after some searching Roy found a casting company prepared to work with him to develop an entirely new production method enabling the one-piece tube to be cast.

Rega won an international award for the RB300 casting, presented by Modern Metals 'awarded in open competition for excellence in the field of Aluminium Die Casting'. In their accompanying letter they wrote: 'we are still trying to figure out how you produce such a long cored hole so accurately'. This made up for never winning any prizes breeding budgies!

For five years, Rega sold a cartridge, the R100, made to specification in Japan. This was followed by the RB100, which was designed and developed by Rega. However, the cartridge had inevitable design limitations as it was being manufactured by an outside company.

In March 1988 the Bias and Elys cartridges went into production in house and sales exceeded 1000 in the first month, five times more than anticipated! The cartridges were a vital step on the way to a complete Rega system.

Completing the system...

In the summer of 1989 the Ela loudspeaker was introduced. Designed and developed at Rega, they were originally produced in Denmark but soon thereafter were manufactured in house.

In 1991, a period of dramatic expansion was heralded with the move into the world of electronics and the launch of two amplifiers, the Elex and the Elicit. The reason for producing these two amplifiers was simple; Rega was presented with a design it could not resist! Most importantly, the amplifiers fit into the company policy - which is to manufacture high quality, specialist hi-fi components that are reliable, consistent and sensibly priced. This development completed the Rega system.

A new factory was built in 1992 on the Temple Farm Industrial Estate in Southend-on-Sea under Roy's design and guidance to house the production of loudspeakers and amplifiers and to ensure room for further developments.

2014....

Over the past 40 years we have come a very long way. Now selling to more than 40 export markets and producing on average 2000 turntables alone every month, Rega now employ's almost 90 people in our purpose built 30,000 sq ft design and manufacturing facility in Essex, England.

Rega continues to grow and develop new products, all of which strictly follow those early Rega virtues of excellent build quality, long life and amazing value for money all backed up by a lifetime warranty against manufacture defects.

Lector Audio ZAX-70 Integrated Amplifier

€1,283.50 (tax incl.)

Lector Audio ZAX-70 - 2 × 70 Watt Solid-State Integrated Amplifier

The ZAX design project marks a new era for amplifiers, introducing new concepts aimed at creating an amplifier capable of driving any load under any input-signal condition. The ZAX design is based on a high-voltage (120 V DC), high-current (±20 A) circuit. To achieve this ambitious goal, our engineers required custom-made components:

• Special high-current, high-voltage transistors capable of handling low-amplitude signals.
• Special output devices featuring transistors capable of handling high currents and equipped with integrated temperature compensation.
• A special high-energy, low-flux-loss AC mains power transformer.

The result is the ZAX design! The ZAX delivers extraordinary sound quality: the FET stage provides a smooth and fluid soundstage, while the high-energy power transistors ensure excellent performance, with detailed high frequencies and authoritative, well-defined bass.

The electronic circuit is based exclusively on discrete components, transistors and FETs (input device), with no integrated circuits used in the signal path! (ICs cannot deliver high current!)

The amplifier features 5 high-level line inputs, an output for the loudspeaker system, and a tape-recording output.

The ZAX-70 replaces the ZAX-60 model. The new integrated amplifier offers increased power of 70 W per channel into 8 ohms and a chassis design that harmonizes with the other models in the range (CDP-603 CD player and Digitube). The ZAX-70 represents the evolution of the ZAX-60 for the “R” series of transistor electronics, characterized by a chassis with rounded sides. The shape is not merely an aesthetic evolution, but also ensures greater chassis rigidity, improved mechanical behavior of the cabinet, and better vibration control.

The ZAX-70 is designed with an exclusively transistor-based circuit, without the use of integrated circuits in the signal path. The bipolar transistors have been selected for their high current capability, reaching a peak current of 12 A! There is only one capacitor in the signal path; it is not electrolytic, but a high-quality film capacitor. There are no limitations on the current capability of the output stage, which can therefore drive loudspeakers with low load impedances.

The volume control is operated by an ALPS Blue Velvet series potentiometer; the control position is indicated by a blue LED, specially designed for its anti-static properties. A volume-controlled passive output allows connection of an active subwoofer or a headphone amplifier.

As with the chassis design, particular attention has been paid to eliminating and controlling every vibration generated by the power transformer.

An aluminum remote control is supplied for operating the amplifier's volume.
