?Vintage style electronics. No integrated circuits in the signal path.
All soldered, connector-free internal design for the purest and most reliable signal path, the only connector used is for the gain switch,
UK-made Carnhill mic input and line output transformers and highpass inductor. The line input uses a custom transformer and the circuit board is prepared for the Carnhill tone. The output is balanced and fully floating and can drive a 600 ohm load up to about 28 dBu.
Traditional 23-position 1073-style gain switch that is also used to select the mic or the line input jack.
Combo XLR/TRS mic and line input jacks and separate output XLR and TRS jacks for flexible connections.
A Neutrik XLR/TRS combo jack with gold over nickel plated bronze contacts is used for the mic input.
Maximum gain on the mic input is 80 dB, enough to handle passive ribbon mics with quiet sound sources.
Switchable impedance on the mic input, 1200 or 300 ohms. Changing the load impedance will change the tone of many mics.
Gain range on the line input: -20 to + 10 dB.
An active instrument input for guitar and bass that passes the signal through the mic input transformer, with selectable input impedance, hi-Z or 100 kohm, by an internal jumper.
Switchable phantom power and absolute phase.
Traditional gain switch plastic knob and metal knobs for the other controls.
The phantom power can deliver up to 10 mA according to the specification standard. The 6.8 kohm phantom power resistors are matched to within 0.1% to maintain good common-mode rejection in the circuit. ??
Selectable 1073-style inductor based highpass filter at 50, 80, 160 or 300 Hz with a slope of 18 dB / octave.
