Vintage Style Pre Amplifier
PRE-73 MKIII
INTRODUCTION
Congratulations on choosing the Golden Age Project PRE-73 MKIII microphone preamplifier!
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 trans-
former balanced, using two different transformers, each one optimized for its purpose. This is the way audio
components were built before integrated circuits became available.
Integrated circuits are small and cheap and they are widely used in most modern designs. It is clear though
that audio components built with modern technology doesn´t always provide the best perceived sound quality
or the type of character that the modern user desires.
On the contrary, the subjective sound quality delivered by vintage equipment is often prefered over the one
delivered by modern units, a situation that is even more obvious now when music is recorded with clean-
sounding digital audio equipment.
This is the reason why so many vintage audio components are cloned and produced again and also why the
vintage originals are often very expensive on the second hand market.
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 classic characteristics have
been heard on countless recordings through the years and it is a versatile sound that works very well on
most sound sources and in most genres.
The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.
FEATURES
- Vintage Style electronics. No intergrated circuits in the signal path.
- Maximum gain in MIC mode is 80 dB, enough to handle passive ribbon mics with quiet sound sources.
- GAIN switch range 20 - 80 dB. GAIN/LINE mode switch, gain is reduced by 30 dB in LINE mode.
- Selectable two position high frequency AIR boost eq, 3 or 6 dB @ 30 kHz.
- Selectable 6 dB/octave two frequency high pass filter at around 40 (HP1) and 170 Hz (HP2).
- Tantalum capacitors in the signal path.
- Switchable impedance in MIC mode, 1200 or 300 Ohms, will change the tone of most mics. The input impedance in LINE mode is 10 kohm.
- 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 jack and separate output XLR and TRS jacks for flexible connections.
- Insert jack for inserting EQ´s and other units.
- Selectable 600 ohm output termination.
- The pcb is prepared for the Carnhill input transformer.
- External power supply to avoid interaction with the audio circuits and transformers.
- A solid build quality that will last many years of normal use.
