Contemporary home organs with unlimited potential

For many decades, Johannus has surprised organists time and again with its Opus series. The concept is simple: complete home organs that offer a rich palette of possibilities. These contemporary instruments will blend seamlessly into the home of any organ lover.



Best-selling organ

It is easy to see why the Opus has been the best-selling organ in the Johannus range for many years. This traditional series with its rich versatility has been, and always will be, perfect for any organ-loving home. Smartly combining contemporary design, innovative technology and the unmistakably refined tones of a genuine Johannus instrument, the Opus 270 and 370 are a must play for today’s organist.



Take a look for yourself and discover

See this for yourself by taking a seat at the two-manual Opus 270, or the three-manual Opus 370. Cast your eye over the instrument and you will notice its diverse disposition of 36 or 42 voices (on the Opus 270 and 370 respectively), operated using illuminated tabs. You will also spot the 32-note AGO pedalboard and three wooden swell shoes.



Fall in love

But it’s only when you actually touch the manuals that you will really sense the rich musical palette that the instrument offers. Start with an adagio, with soft strings and labial voices, then end in a virtuosic presto using three rumbling 16-foot stops in the pedal. The organ’s multichannel audio system distributes your inspirational music over many built-in speakers, producing the pure and natural sound of a pipe organ. Quite simply, this is an organ to fall in love with. Whether you prefer to play American classic, baroque, historic or symphonic pieces, the Opus will respond intuitively to the registrations and settings that you select. What’s more, it will respond with overwhelming passion. In the plenum, the Opus reveals its power, while in a cantus firmus, it spreads a wonderful calm throughout your home.



Powerful but elegant at the same time

This is an organ that will make you feel completely at ease. You can throw yourself into a tutti, giving it your all, and improvising as you go. Or just take a seat behind the manuals, relax and marvel at the simple layout of the extensive options. A powerful but elegant instrument.



Pure and authentic

The difference in sound between Johannus Opus and pipe organs is very small indeed. Using Real Time Sampling technology, the Opus 270 and 370 incorporate flawless recordings of famous pipe organs, rather than relying on simulation technologies. Purity and authenticity are evident each time you touch the Opus, thanks to the new OranjeCore technology, developed by Johannus.The pure, clear sound of the Opus 270 and 370 will bring the pipe organ into your living room. In fact, thanks to the selection of styles and twelve reverb programs, you won’t have just one organ, but instead a whole range of different pipe organs in the comfort of your own home.



Choose your own color

Not only does Johannus offer a rich variety of sounds, but you can also choose from a range of colors. The console of the Opus 270 and 370 can be supplied in any color you want. That makes it the perfect instrument for your home, capable of matching almost any interior. We put a lot of thought into that, and the same applies to the design. Both the Opus 270 and Opus 370 feature sleek lines and a contemporary console. And so the Opus is always up-to-date.
