Modern 500 Series Mic Pre with Serious Old-school Swagger

Get to know them!

Taking the circuit topology from its renowned Sta-Level tube compressor and pouring it into a single-slot 500 Series microphone preamp, Retro Instruments has created a new primary color to include in every recording engineers’ palette. Brimming with vintage vibe, the 500PRE has High and Low gain select for loads of flexibility to dial up a range of crisp clean tones or creamy tube overdrive, and with a separate output trim, you can smack it hard without fear of clipping. With three TAD 12AT7 new-production tubes and high-quality CineMag transformers, the 500PRE’s throwback sound is set on a modern foundation with the high headroom and low-noise performance you’ve come to expect from new-school gear. The recording gurus at Sweetwater agree: Retro Instruments’ 500PRE is taking echoes from the past and projecting them far into the future.

Control your color with gain select

Gearheads love their tubes, and it’s no wonder why. Inserting them into a signal chain adds instant character and warmth, snugging an instrument or vocal into the fabric of a mix in a way unachievable by any other method. Many engineers think of tube preamps as having a built-in compressor and EQ section, essentially preprocessing a signal in a distinctly smooth and musical fashion. To coax as much tubey goodness as possible out of the 500PRE, Retro Instruments equipped it with three TAD 12ATZ new-production tubes in switchable 2-stage and 3-stage amplifier configurations and independent input and trim knobs for incredible tonal control.
