About: Triton Audio D2O Tube/Fet 500 Series Mic Pre

This low noise discrete microphone preamp is a further development of the famous German V series preamps. These are known as one of the best in the market. At Abbey Road the V series were used to record songs of big names in the music industry like The Beatles and Pink Floyd. This is the D2O 500 series version, it comes in a single slot format.

The D2O 500 series is the perfect tool for microphones with a relatively low output like ribbon microphones. The single unit preamp is housed in a rugged aluminum enclosure. The portable format is ideal for the new generation of mobile recording interfaces.

Various functions can be selected like hi gain, all Fet, hybrid tube-Fet circuit, creating your own unique sonic character.

Low noise / low esr power supply

In single ended preamp designs the quality of the power supply is crucial, D2O is fitted with a discrete low esr voltage regulator built with low noise components enabling optimal performance to the amplifier circuit.

Switchable transformer ratio / input impedance

By selecting the transformer ratio switch a selection between a 1:1.75 (LO) or 1:3.5 (HI) transformation ratio can be made. Besides setting voltage gain, this also switches the input impedance of the amplifier between 2.25KOhm and 6.25 KOhm. Different transformation rate and impedance selection options are very desirable as they allow for more sonic options from the connected microphone.

Selectable all Fet or Tube-Fet circuit

The Tube-Fet switch determines whether D2O functions as an hi gain, all Fet or hybrid Tube-Fet circuit, each with its unique sonic character.
