Golden Age Project PRE-73 MKIII, mic preamp

  • 3 295:-

The MKIII has the following new 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

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. This is the  way audio components were built before integrated circuits became  available. 

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.

- 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.
