Golden Age Project PRE73MK3 PRE-73 MKIII 1-Channel 1073 Style Mic Pre, Direct Box

The PRE-73 MKIII is a one-channel vintage style microphone-, line- and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The in- and output is transformer balanced, using two different transformers, each one optimized for its purpose.

The circuit used in the PRE-73 MKIII is similar to the preamp section in the classical 1073 module, with a corresponding sound character that is warm, punchy, sweet and musical. These versatile traits have been heard on countless recordings, and they work very well for most sound sources and in most genres.

The MKIII has the following features, compared to the MKII:

• Tantalum capacitors in the signal path.
• Selectable two position high frequency AIR boost eq, 3 or 6 dB @ 30 kHz.
• Selectable two frequency high pass filter, 6 dB/octave at 40 or 170Hz.
• The PCB is prepared for the Carnhill input transformer.
• Revised and less complicated GAIN switch with a separate switch for MIC/LINE selection.
• All GAIN settings can also be used in LINE mode

Golden Age Project PRE-73 Mk2 Features:

• Vintage Style electronics - no integrated circuits in the signal path.
• Maximum gain on the mic input is 80 dB, enough to handle passive ribbon mics with quiet sound sources.
• Gain range on the Line input: -20 to + 10 dB.
• Switchable impedance on the mic input, 1200 or 300 Ohms, will change the tone of most mics.
• Switchable phantom power and absolute phase.
• A high-impedance instrument input for any sound module, electric guitar or bass.
• A simple but effective 4-step LED output level meter.
• The output level control makes it possible to make fine gain adjustments and also to overload the main gain stage(s) for more character and then lower the signal to a suitable level before the output stage.
• Combo XLR/TRS input jacks and separate output XLR and TRS jacks for flexible connections.
• Insert jack for inserting EQ´s and other units.
• Selectable 600 ohm output termination.
• External high power power supply to avoid interaction with the audio circuits and transformers.
• A solid build quality that will last many years of normal use
