Golden Age Audio PRE-73 DLX MKII

Switching between 1200 and 300 ohms changes how the preamp loads your microphone. The 1200-ohm setting provides a more open, standard response, while the 300-ohm setting can darken the tone and increase output, which is particularly useful for adding character to ribbon or dynamic microphones.

The AIR EQ adds a subtle high-frequency boost of 3 or 6 dB at approximately 30 kHz. This helps restore a sense of 'air' and clarity to your recordings that might be lost during the capture process, without making the signal sound harsh or brittle.

Yes. By using the output pad, you can turn up the input gain to push the transformer and discrete circuitry into a more saturated, vintage-style harmonic distortion while keeping the final output level at a manageable volume for your interface.

Yes, the DI features selectable impedance, allowing you to optimize the signal path for either high-output active instruments or standard passive guitars and basses to ensure the best frequency response and gain staging.

The PRE-73 DLX MKII is designed as a rackmount unit. It uses an external power supply, which helps keep noise floor interference away from the sensitive audio circuitry inside the chassis.

The built-in high-pass filter is an analog circuit with an 18 dB/octave slope. It is highly effective at removing low-end rumble or mud at the source, providing a cleaner signal before it ever reaches your digital-to-analog converter.
