One-channel vintage style microphone-line and instrument preamplifier
The signal path uses only discrete components like resistors, capacitors and transistors. The microphone and line input and the line output are transformer balanced, using three 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 PREQ-73 PREMIER is similar to the preamp and the equalizer 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.
Caractéristiques
No integrated circuits in the signal path.
14 dB output pad allowing the user to overdrive the output stage and transformer
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
Maximum gain in mic mode is 80 dB, enough to handle passive ribbon mics with quiet sound sources.
Switchable impedance in mic mode, 1200 or 300 Ohm, will change the tone of most mics. The input impedance in line mode is 10 kOhm
Combo XLR/TRS input jack and separate output XLR and TRS jacks for flexible connections
Gain switch range is 20 - 80 dB. Line mode switch, gain is reduced by 30 dB in line mode
Switchable phantom power and absolute phase
A high-impedance instrument input for any sound module, electric guitar or bass
Selectable 6 dB/octave high pass filter at around 80 Hz (HP1) or 200 Hz (HP2)
