Golden Age Project PRE-73 JR MKII Vintage-Style Microphone Preamplifier

Description

TheGolden Age Project PRE-73 Jr MKIIis a single-channel vintage-style microphone and instrument preamplifier. The signal path uses only discrete components such as resistors, capacitors, and transistors. The input and output stages are transformer balanced, with each transformer optimized for its purpose. This MKII version features a small format perfectly suited to the UNITE MKII rack kit.

By employing vintage analog circuitry and avoiding integrated circuits, the PRE-73 Jr MKII is able to deliver a prized vintage sound with up to 70 dB of gain. The circuit in the unit is similar to the classic 1073 module with a corresponding sound character that is warm, punchy, sweet, and musical. To reduce unwanted low-end rumbles, engage the 6 dB high-pass filter at either 40 or 170 Hz. To add presence to vocals and instruments, engage the two-position AIR boost to add 3 or 6 dB at 30 kHz. The preamp can supply 48V phantom power for microphones that require it.

Features

• Vintage-style Class-A electronics; no integrated circuits in the signal path; no surface mount components
• GAIN switch range from 20 to 70 dB
• Selectable two-position high-frequency AIR boost EQ, 3 or 6 dB at 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
• High-impedance instrument input for any sound module, electric guitar, or bass
• 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 EQs and other units
• Circuit board is prepared for the Carnhill input transformer.
• External power supply to avoid interaction with the audio circuits and transformers
