The Trichord Research Dino Mk2 Phono Stage with Never Connected PSU is a high performance phono amplifier and power supply unit, designed for transparency and realism. It will maximise the performance of a wide range of quality cartridges from ultra-low output Moving Coils to high output Moving Magnet types.
The Trichord Research Dino Mk2 Phono Stage with Never Connected PSU is user adjustable with a set of four DIP switches on the underside of the unit for ease of access. These switches allow for adjustment of cartridge loading and gain setting. The circuitry is signal non-inverting and constructed using high performance, audio grade bipolar and JFET operational amplifiers, metal oxide resistors and ultra low impedance capacitors throughout for lowest possible noise.
The RIAA equalisation network is fully passive and located between two active gain stages. The capacitors and resistors used in this stage are very close tolerance audiophile types. Two state of the art ultra low impedance, low noise wide-band voltage regulators are employed to power both channels and are largely responsible for the high sonic performance of the Dino
The Trichord Research Never Connected Power Supply Unit has completely different electronics to the standard 'Dino+' power supply. Instead of an oversized toroidal transformer, there is a PCB mounting variety followed by the revolutionary noise reduction circuitry that is called 'Never Connected'.
Although the regulation circuit is physically connected to the incoming mains, it is disconnected electrically. A monitoring circuit detects the portion of the sine wave that is charging the first of a pair of electrolytic capacitors. Once this first capacitor is fully charged, the diode bridge rectifier turns off and a mosfet switching circuit transfers the charge from the first cap to the second. This cycle is repeated continuously.
At no point in time is the regulation circuitry electrically connected to the incoming rectified mains - hence the term 'Never Connected'. The overall result is a large and measurable reduction in mains borne noise.
This dramatic reduction of mains borne noise enables the Dino phono circuit to give of its very best.
