Preamplifier DP 2000 includes a processor/encoder exploiting the exceptional directivity of the ultrasounds to feed the center lane. In order to profit from the sound "Delta", it is enough for you to replace your pre-amplifier by the DP 2000 and to integrate the central speaker 25 HE. GUISTON

2000 : THE DELTAPHONIE®
a process GUISTON
Deltaphonie® is a technique reserved for the top-of-the-range audio-systems. Three ways are necessary to obtain a listening in "Delta":
two sided and one central.
of Infra-low sound
Allows to hear the sounds of extreme practically inaudible low registers with the current Hi-Fi material. Inserted between your preamplifier and your Stereo amplifiers, the BCH 2000 gets an exceptional extreme low register . Width and depth of the sound scene guaranteed! Replace efficientaly a Sub-Woofer box in a home-cinema system. (BEWARE! Your amplifier must at least have a power band-width of 20 Hz in the low register)
Mono blocks in pure class A
High Definition Audio Amplifier .
It profits from a particular assembly of the power-transistors completely innovating. It functions in a voltage amplification like three-electrode tubes in order to obtain the same musical quality from it.

Power Supply A160 + Ampli B50
Amplifier in 2 blocks separated to transform a passive speaker into active . Circuits mirror. B+ Class. Separate active power supply.
Audio Tube Amplifiers
A 10 - A 30 - A 120 + S 1200
Few manufacturers in the world DO control the OTL technique!
It is however the best of high-fidelity... The tubes of power are connected directly to the loudspeakers,
without the losses due to the Output transformers.
All the dynamics of the tubes is preserved, and the band-width is not cut. From 2 Hz to 200 Khz without attenuation!
