The PRE-73 Jr is a one-channel vintage-style microphone and instrument preamplifier. The 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.

Integrated circuits are small and cheap and widely used in most modern designs. It is clear, though, that audio components built with modern technology don'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 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 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 Jr Premier 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… read more to nearly everyone.

Features:

- Vintage Style class-A electronics. No integrated circuits in the signal path. No surface mount components.
- GAIN switch range 20 -70 dB.
- 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).
- Switchable phantom power and absolute phase.
- A high-impedance instrument input for any sound module, electric guitar or bass.
- A simple signal LED indicator.
- The output level control makes it possible to do fine gain adjustments and also to overload the main gain stage 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.
- UK-made Carnhill input and output transformers, tantalum and plustyrene capacitors and mostly soldered internal connections.
- External power supply to avoid interaction with the audio circuits and transformers.
- The small format makes it possible to mount 4 units in GA's 19-inch rack kits.
- A solid build quality that will last many years of normal use.
