The invention relates to an electronic organ with two or more manuals and pedal bass, in which all sounds are generated by a common generator group and varied by filters or mixing circuits for the various manuals in the sound, and reverberated and possibly by effect circuits, such as vibrator, Tremolo, etc. Such electronic organs are known, the known electronic organs usually work only with a single speaker or a single speaker assembly (ordered from high and Wieftonlautsprechern). The actual sound source is punctiform in these known organs, but at least compressed to a limited location, so that the playback is monophonic. Since an organ, however, due to their normally relatively large dimensions in nature forms a polyphonic orchestra, the performances produced by the known electronic organs are poorly suited to imitate the sound of working with spatially distributed Orgelipfeifen original organ over invention is therefore the object of the known electronic organs of the type described in the opening paragraph, so that they are suitable to convey to the listener a sound effect similar to that of an original organ.

The object is inventively achieved in that the sound varied tones of each manual to separate amplifiers and these are placed on separate, set up on a stereo speaker, the Pedaloass either-mixed evenly channels or as a third channel via another amplifier and speakers is played.

The solution according to the invention therefore makes use of the known electronic stereophony in order to render the tones or sound combinations that can be generated with the various manuals spatially separated, as is the case with a normal organ-pipe organ. As a result, an organ playing is possible, which is characterized by a previously unknown for electronic organs transparency and PL unit of sound. In addition, with the inventive electronic organ, the melody and accompaniment can be separated from each other, as it is used to the listener from the concert hall or from oak trees with several organ brochures.

Especially when using an additional rhythm device, the listener is given the illusion of having an orchestra in the room. Particularly impressive presents the invention z. B. in the game of classic joints, since it is possible by the separate representation of the producible with the individual nano-sounds or tone combinations also a separate perception nichtgleichsinniger runs.

A further improvement and completion of the surround sound effect can according to a development of the invention consist in that a Hall generator is arranged in each of the individual channels, preferably in both manual channels.

Each Hall generator can be arranged for further refinement of the space-1-long effect according to a further development of the invention switching technology so that the reverb part generated by it is mixed up the own manual channel again. Alternatively, it is also possible to arrange each Hall generator circuit technology so that the reverb part of his own manual generated by him is mixed with the other manual channel.

Another way of exploiting a reverb effect to generate a surround sound effect may be that only in a Hall generator, the mixed product of both manual channels is repressed and the reverb content of both channels is mixed again, both decoupled manual channel to avoid tubersprechens is connected to the other manual channel at the Hall generator input and output.

The decoupling can be done for example by a resistance circuit. But it is also possible that for decoupling electronic valves in the form of single or multi-stage amplifiers between Hall generator input and output and each nanual channel are arranged.

In order to exploit the advantages of stereophonic organ playing even with small home stereos whose speakers are not able to reproduce the relatively strong organ bass, the hischproduct of both manual channels and the bass channel sparing it according to another embodiment of the invention via a phantom Medium channel, wherein the output of the phantom Nittelkanals is reproduced on a suitable for the purpose woofer. Special speaker effects, such. 13. Space sound or Leslie, can be played either on the phantom Nittenkanal or the two stereo channels.

Another possibility for expanding the sound body of the electronic organ according to the invention may be that additional effect registers, such as sustein, rhythm, harp, trumpet, piano, spinet, etc., are provided, the instrumentalities that can be generated with these additional effect registers. Imitations of another, consisting of at least one amplifier and a speaker channel can be played. The further channel can also be formed by one of the nano-channels, with tones of both nano-ales being added to the remaining manual channel.

Embodiments of the invention will be described below with reference to the drawings.

1 shows a first embodiment of the electronic stereo organ according to the invention; FIG. 2 shows a second embodiment of the electronic stereo organ according to the invention; FIG. Fig. 3 shows a third embodiment of the inventive electronic stereo organ.

The illustrated in Fig. 1 in the form of a schematic circuit diagram stereo organ has a lower manual 2, an upper manual 4 and a bass pedal 6. The output product of the lower manual 2 is fed to a preamplifier 10 via a decoupling resistor 8. The preamplifier 10 feeds via a decoupling resistor 12, the left output 14 for a stereo Eanal a stereo system.

The output product of the upper manual 4 is supplied to a preamplifier 18 via a Sntkopplungswiderstand 16. This feeds via a further decoupling resistor 20, the right output 22 for the other stereo channel of the stereo system.

The bass pedal 6 feeds a variable resistor 24, with which the size of the output product of the bass pedal 6 can be adjusted. The variable resistor 24 is connected to a switch 26 which supplies the output of the bass pedal 6 in its left switching position of a bridge arrangement. The bridge arrangement consists of two bridge resistors 28, 30 and one potentiometer 32. By adjusting the bridge arrangement, the two preamplifiers 10 and 18, an equal proportion of the output of the bass pedal 6 are supplied.

The 'leftover compound 14' is further supplied via a decoupling resistor 34 to a further preamplifier 36. The standing on the right output 22 Tongemisch is supplied via a decoupling resistor 38 to a preamplifier 40. The two preamplifiers 36 and 40 feed via a decoupling resistor 42 and 44 a Hall generator 46th The Hall component generated by the Hall generator 46 is supplied to the clay mixture ar.l left output 14 via a decoupling resistor 48, an amplifier 50 and another decoupling resistor 52 and mixed. Furthermore, the Hall component generated by the Hall generator 46 is supplied to the right-exit 22 sound mixture via a decoupling resistor 54, an amplifier 56 and another decoupling resistor 58 and mixed.

The output of the Hall generator 46 is further connected to a switch 60, which in turn has contact with a switching contact of a switch 62. The switch 62 is also connected via a decoupling resistor 64 and an internal organ preamplifier 66 to an internal organ main amplifier 68, which feeds a loudspeaker 70. The decoupling resistor 64, the internal organ preamplifier 66, the internal organ main amplifier 68 and the loudspeaker 70 therefore constitute a third channel with respect to the two stereo channels of the stereo system.

When the switch 60 is switched out of the switched position shown in FIG. 1 to the right, the connection of the Hall generator to the third channel is interrupted.

In this case, the third channel is supplied to the uncoupled, standing in front of the Hall generator 46 Tongemisch only directly on the decoupling resistor 72.

The two switches 26 and 62 are, as indicated by the dashed line, coupled together. This means that the two switches 26 and 62 can only be changed like a single one. When the two switches 26 and 62 are switched out of the switching position shown in Fig. 1 in the other (right) switching position, only the deni third channel and not the two stereo channels supplied with the bass pedal 26 Tongemisch is supplied.

In the embodiment shown in Fig. 2 are circuit parts corresponding to certain circuit parts in Fig. 1, denoted by the same reference numerals as in Fig. 1. The essential difference between the embodiment shown in FIG. 2 and the embodiment shown in FIG. 1 is that a separate IIall generator 41, 43 is provided for each manual channel. Each of the two Hall generators 41, 43 is bridged by a resistor 13, 21, so that at the output of the two Hall generators 41, 43 is a mixture of the unattenuated and your reverberated sound component of the relevant manual channel. This mixture is supplied in the liiiken manual channel via a decoupling resistor 15 to both the left stereo output 14 and the amplifier 36. In the right Hanual channel this mixture is supplied via a decoupling resistor 23 to the right stereo output and the amplifier 56. The output products of the two amplifiers 36 and 56 are supplied to the switch 60 via the resistors 42 and 421 and via a decoupling resistor 49. The remaining part of the basic circuit corresponds to the already described in connection with FIG. 1.

The Ausführurigsform shown in Fig. 3 differs from the embodiment shown in Fig. 2, characterized in that each manual channel a verhalter share of the other manual channel is fed it. The output of the amplifier 10 in liiiken manual channel is fed to a Hall generator 45, which feeds the reverberated portion of the left manual channel between the two resistors 20, 38 in the right manual Eanal. The output product of the Yerstärkers 18 in the right-hand Eanal is supplied to a Hall generator 47, which feeds the reverberated portion of the right-hand manual channel between the two resistors 12, 34 in the left manual channel.
