Product Overview
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:
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.
- 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
- 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
