• 50dB Class A Line preamplifier, bridging input impedance, balanced and floating.

• All discrete Class A Ultra High Impedance J-Fet Direct Input on a high quality Neutrik Jack. The DI circuit is ahead of the Mic Input transformer, so the transformer is on when in DI mode.

• Class A single ended, 2N3055 driven, high headroom B283 output stage.

• Individual Neutrik gold plated XLR connectors for microphone and line inputs.

• Gold Plated Neutrik XLR output.

• PAD: 20dB Mic input attenuation ahead of the input transformer to avoid overloading it.

• HI PASS FILTER: Active all discrete Class A 3rd order Bessel, 80Hz Hi Pass Filter. 18dB/octave slope.

• OUTPUT control to allow overloading of the preamp.

• External linear PSU to avoid electromagnetic radiation into the audio transformers (a.k.a. hum).
