Golden Age Project PRE-73 DLX PREMIER Single Channel 73-Style Mic Pre

Capture the revered warmth and clarity of classic 1970s British console preamps with the Golden Age Project PRE-73 DLX PREMIER. This single-channel mic preamplifier delivers up to 80 dB of gain on the mic input, ensuring even quiet ribbon microphones and low-level sources are amplified cleanly without noise. The switchable input impedance (300 or 1200 Ohms) lets you shape microphone tone and response, providing sonic flexibility for diverse recording scenarios.

Connectivity is comprehensive and versatile. A combination XLR-1/4″ input accommodates microphones and line-level signals, while a dedicated 1/4″ DI input supports Hi-Z instruments with selectable impedance options (Hi-Z or 100 kOhms) via an internal jumper, ensuring optimal signal matching for guitars and basses. Balanced XLR and 1/4″ TRS outputs maintain signal integrity for professional routing.

The preamp features a high-pass filter with selectable inductor-based cutoff frequencies at 50, 80, 160, or 300 Hz and a steep 18 dB/octave slope. This allows precise removal of unwanted low-frequency rumble or stage noise without compromising tonal character. Complementing this is the AIR EQ, which boosts frequencies around 30 kHz by 3 or 6 dB to add a subtle yet noticeable brightness and presence to your recordings.

Output dynamics are carefully managed with a transformer-coupled output stage that can deliver a maximum output level of +28 dBu at 600 Ohms, suitable for driving professional consoles and interfaces. An output pad offering attenuation levels of -7, -14, -21, or -28 dB is positioned after the transformer, enabling you to push the preamp’s input stage harder for harmonic character without overloading subsequent gear.

Additional features include phantom power capable of supplying up to 10 mA through precision-matched 6.8 kOhm resistors, ensuring stable operation with condenser microphones. A 4-segment LED meter provides clear visual monitoring of output levels, while relay-switched controls reduce signal path interference for pristine audio quality. The external power supply isolates the unit’s electronics from noise and interference, further enhancing sonic purity.

Constructed with UK-made Carnhill transformers and high-grade polystyrene capacitors, the PRE-73 DLX PREMIER combines vintage circuitry with modern build standards. The hand-soldered, connector-free internal design ensures a reliable, low-noise signal path. Its front-panel layout includes traditional 23-position gain switching, phase reverse, and impedance selection, offering tactile control reminiscent of classic studio hardware.

This preamplifier is ideal for engineers and producers seeking a faithful recreation of the iconic 73 preamp sound with extensive tonal shaping and connectivity. Its robust design and precise components deliver consistent, professional-grade audio performance suitable for studio and live environments.
