The Golden Age Project PRE-73 DLX is a one-channel vintage style microphone-, line- and instrument preamplifier, with a number of improvements and features compared to the PRE-73 MKII, including:

  • Tantalum capacitors in the signal path
  • Selectable 1073-style high pass filter, 50, 80 , 160 and 300 Hz
  • Output Attenuator -7, -14, -21 and -28 dB (located after the output transformer) allows overdriving the output stage and the output
    transformer for added character by lowering the output signal to a suitable level.
  • The circuit board is prepared for Carnhill Mic and Line transformer and high pass inductor.
  • The Insert jack can be switched in/out from the front panel.
    • An internal jumper can select that the Insert jack always has an output signal.
  • Switchable 600 ohm Output Termination and Ground Lift on the back panel.
  • Selectable Active or Passive DI input and selectable input impedance in active mode, Hi Z or 100 kohm, by internal jumpers.
  • The DI signal can be selected to pass or bypass the mic input transformer by internal jumpers.
  • Relays are used to control internal switching for DI input, Phantom power, Mic Low Z, Insert and Phase for shorter circuit board signal paths.
    • Relays are controlled by front panel switches.
  • Revised gain switch for added headroom
  • Circuit board star grounding scheme
  • Revised power supply with separate regulators for the audio circuits andrelay and LED circuits

The signal path uses only discrete components like resistors, capacitors and transistors. The line and microphone input and the line output are transformer balanced, using three different transformers - each one optimized for its purpose.

The sound quality delivered by vintage equipment is often prefered over that delivered by modern units, a situation that is more obvious now when music is recorded with clean-sounding digital audio equipment.

The circuit used in the PRE-73 DLX is similar to the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These traits have been heard on countless recordings and it's a versatile sound that works well on most sound sources and in most genres.

Golden Age Project PRE-73 DLX Features:

  • Vintage Style electronics - no integrated circuits inthe signal path.
  • Maximum gain on the mic input is 80 dB, enough tohandle passive ribbon mics with quiet sound sources.
  • Gain range on the Line input: -20 to + 10 dB.
  • Switchable impedance on the mic  input, 1200 or300 ohms, will change the tone of many mics.
  • Switchable phantom power and absolute phase.
  • A high impedance instrument input for any soundmodule, electric guitar or bass.
  • A simple but effective 4-step LED output level meter.
  • The output level control makes it possible to makefine gain adjustments and also to overload the main gain stage(s) for morecharacter and then lower the signal to a suitable level before the outputstage.
  • Combo XLR/TRS input jacks and separate output XLR andTRS jacks for flexible connections.
  • Insert jack for inserting EQ ´s and other units.
  • External high power power supply to avoid interactionwith the audio circuits and transformers.
  • A solid build quality that will last many years of normal use.
