Vintage-Style Microphone Preamplifier

The Golden Age Project PRE-73 Jr MKII is 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.
