Product Description

• 80dB Class A Microphone preamplifier, HI-LO selectable minimum input impedance, balanced and floating. High gain positions show a higher impedance, ideal for old ribbon mics.
• 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 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 ).
• Carnhill Input and Output transformers.
• 3 gain stage, genuine B283 gain card modular construction.
• Marconi style knobs and vintage style engraved pushbuttons.
