Trichord Research D300 Monobloc power amplifiers

Sorry, This product is no longer available



We have decided at long last to replace the old 'Alecto' mono and stereo power amplifiers with a new generation of technology. The D300 mono amplifier is the first in a new product range that incorporates highly efficient 'class D' output stages combined with specially manufactured toroidal transformers for a more traditional power supply. 'Never Connected' technology is used to provide power to the front end amplifier preceding the class D section. Please note - D does not stand for "digital" The letter D used to designate this type of amplifier is simply the next letter after C, and does not stand for digital. Class D and Class E amplifiers are sometimes mistakenly described as "digital" because the output waveform superficially resembles a pulse-train of digital symbols, but a Class D amplifier merely converts an input waveform into a continuously pulse-width modulated (square wave) analog signal. (A digital waveform would be pulse-code modulated.) At only 8.5" wide and 2" high, these amplifiers are relatively small and ideally suited to multiple amplifier set-ups. Balanced and single ended (phono) operation are catered for with a switch on the rear of the unit. Price is for a pair of monoblocs.
