Magic TRIck revision 3 front panel. First beats of Haendel's Messiah creates a display bar for controlling volume and other adjustments.

Analog Signal Processor boards (the set of active filters and equalization circuits well known from Linkwitz’ projects) driving eight LM3886 power amplifiers. Every loudspeaker in this system is directly driven by its own power amplifier. Tweeters and midwoofers are helped by four subwoofers (multisub system a ’la Geddes style). Such an active multichannel system can sound really well. Not quite magic, but close.

Magic TRIck will soon change into 3 main channel system for stereo program reproduction. Michael's Gerzon 3x2 Optimal Reproduction Matrix for multispeaker stereo is to be implemented in the Analog Devices ADAU1701 DSP chip. Pretty sophisticated project made fairly easy:

Trifield decoder implementation in the Analog Devices’ Sigma Studio software. No special programming skill is necessary, as the decoder is built of predefined blocks and connections among them. Some blocks, however, will have their parameters set up by a microcontroller.

Here comes the Stratobaffle - an open baffle full-range speaker. Right on 60th anniversary of the famous Fender Stratocaster guitar.

Stratobaffle multi-layer cardboard prototype equipped with the high-end full-range driver Visaton B200.

Stratobaffle main parts before assembling.

The Fender Stratocaster guitar turns 60 this year. Its well-known shape was used to design the Stratobaffle speakers.

Let’s celebrate Fender Stratocaster 60th anniversary together with Stratobaffle speakers.

Stratobaffle in an open baffle design. No speaker enclosure means that both sides of the driver radiate sound. Not necessarily loud, but very detailed and open sound.
