Product Description

A one channel vintage style Compressor / Leveler, the COMP-3A's signal path uses only discrete components like resistors, capacitors and transistors. The input 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.

Golden Age Comp3a Discreet Optical Compresser Limiter Features
  • Vintage style electronics. No integrated circuits in the signal path.
  • Transformer balanced input and output. Can drive almost any load - balanced or unbalanced.
  • Selectable output transformer loading resistors by an internal jumper, will affect the high end frequency response.
  • Uses a classic T4-style electro-optical attenuator to control gain with program dependent attack and release times.
  • Very simple to operate with only two main controls, Gain and Peak Reduction.
  • HF control can make the side-chain circuit more sensitive to mid and high frequency content.
  • A big meter selectable to show gain reduction or output level at two different reference levels.
  • Hardwire bypass switch for easy comparisons.
  • XLR and TRS input and output jacks for flexible connections.
  • Link jack and switch for connecting to another unit for stereo operation.
  • All external controls located on the front panel.
  • External power supply to avoid interaction with the audio circuits and transformers.
  • Compact 2RU half rack format. Two units can be mounted with our 19-inch rack kit, the UNITE BIG.
  • A solid build quality that will last many years of normal use.
Integrated circuits are small and cheap and widely used in most modern designs. The drawback is 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. The subjective sound quality delivered by vintage equipment is often preferred 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 COMP-3A is based on a classic design that uses an electro-luminescent panel and a photoelectric cell to control gain. This gives the COMP-3A a unique, program dependent compression characteristics. In addition, the vintage style signal path adds a wonderful and musical character to the sound. The ease of use with only two main controls makes it very simple to achieve the desired sound. These attributes has made the original units a favorite of engineers and musicians worldwide.

Golden Age Project Pre73 MKIII Microphone Preamp
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 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 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.

Golden Age Project Pre73 MKIII Microphone Preamp Features
  • Vintage Style electronics. No integrated 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.
