Opus 25

The Opus 25 is the most popular sold organ in the world. The reason is that it simply gives you the most value for money. A lovely console, 36 voices and 12 intonations surpass all expectations.

12 different organs

The magnicent variety of the organ literature requires organs diverging in sound, intonation and tonal quality. The Johannus Opus 25 offers the organ lover three basic varieties: Baroque, Symphonic and Romantic, each of which has as many as four different intonations: Classical, Solo, Hymn and Trio. Twelve organs in all. Get ready for an overwhelming musical experience

The advanced Setzer system

You can save the most lovely combinations in the Selzer system; no less than 48 different combinations.

Opus 25

All diapason and reed stops are in C-Cis chest layout

All diapason and reed stops are in C-Cis chest layout, just like in most pipe organs. Our multi-channel system allows these voices to sound very natural in your living room.

The acoustic Stereo 3D allows you to constantly adjust the reverb and set it according to your living room. You will feel as if you are actually playing in a church.

Physiological Tone Control

All the Opus series organs have a physiological tone control. What exactly does this mean? When an organist closes the swell box of a pipe organ, the swell boxes close slowly and volume gradually decreases, especially of the higher frequencies. This creates a sonorous sound and organ playing assumes a typical, modest character.

Dynamic chiff

Blowing an organ pipe creates an effect known as chiff. This forms an essential component of the overall sound. In most electronic organs, chiff is created by computer simulation. The result ranges from poor to reasonable.

In Johannus organs, however, the original recording of organ pipes is used. Each time when a different key is pressed, the fundamental tone is preceded by chiff. When the same key of a pipe organ is pressed in quick succession, the air column remains inside the pipe. This causes part of the chiff to be lost, dependent on the speed of the note repetition. Although this effect is typical of a pipe organ, it was always lacking in pipeless digital organs, because it was not technically feasible.

Johannus Research proudly presents a new breakthrough in organ technology. From now on it is possible to mirror the pipe organ effect: a tremendous step forward!
