Midas 502 V2 — The XL4 Preamp in a 500 Series Module

The Midas Microphone Preamplifier 502 V2 is a single-channel 500 Series module that brings the award-winning Midas preamp sound — long associated with legendary live consoles — into a compact, rackmount-friendly format. Built around four discrete ultra-low-noise input transistors, the 502 V2 captures the warmth, depth, and spatial detail that front-of-house engineers have relied on for decades. For those seeking genuine XL4 console character in a modular preamp, the 502 V2 is an excellent solution.

Standout Features That Set It Apart

What makes this module special is the inclusion of the classic XL4 swept highpass and lowpass filters, ported directly from Midas's iconic live performance console. A switchable transformer-balanced output stage (TX) gives engineers an instant A/B between a clean electronic output and a more saturated, vintage-flavored transformer sound — a versatility rarely found at this tier.

Gain Range and Headroom — Built for Demanding Sources

Engineered for both delicate ribbon microphones and high-output sources, the 502 V2's input stage operates without a pad, accommodating a broad spectrum of signal levels.

• Maximum Input Level: +24 dBu without pad — handles loud sources cleanly
• When recording ribbon microphones with low output, the total gain range of -20 dB to +80 dB ensures clarity without noise.
• Input Gain Steps: 0 to +60 dB in 5 dB increments via 12-position rotary switch — precise recall between sessions
• Output Trim: ±20 dB variable potentiometer — shapes output coloration independently of input drive

Classic XL4 Filters — Surgical Tonal Control

The same swept filter network that helped define the XL4 console's signature sound is built into this module, with independent in/out switching for each band.

• Highpass Filter: 10 Hz to 400 Hz (-3 dB points) — removes rumble and proximity effect
• Lowpass Filter: 1 kHz to 40 kHz (-3 dB points) — tames harsh top end on bright sources
• Engineers can instantly A/B filter settings using independent illuminated IN switches for each band.

Output Stage, Metering, and Operational Controls

This model combines a clean electronically balanced output with a discrete transformer-balanced alternative, plus detailed metering and studio-grade switching.

• Output Stage: Switchable electronic or transformer-balanced (TX) — matched levels for easy A/B
• Metering: Dual 11-segment rotary LED meters (-20 dBu to +20 dBu) — separate input and output readouts
• Phantom Power: +48V switchable — powers condenser microphones
• Other controls include polarity reverse, power-up mute relays, and illuminated switches for intuitive and safe operation.

Who Is It For

Studio engineers, producers, and live-sound technicians who need a high-headroom, characterful preamp for any 500 Series chassis will find the 502 V2 excels on vocals, acoustic guitar, and kick drum. Pairing it with a Midas L6 or L10 rackmount chassis unlocks the twin aux output for active mic/line splitting on stage or in the studio.
