Lindell Audio RE-51 Retro 500 Series Microphone Preamp and EQ Module

Elevate your audio recordings with the Lindell Audio RE-51, a single-channel solid-state preamp and EQ designed specifically for 500 Series racks. It delivers classic vintage warmth combined with modern clarity, allowing precise tonal sculpting essential for professional audio engineers and producers.

The RE-51’s 2-band passive EQ provides selectable frequency ranges—30 Hz, 60 Hz, or 100 Hz on the low end, and 4 kHz, 8 kHz, or 14 kHz on the high end. This flexibility lets you enhance bass punch or add shimmering presence exactly where your mix demands it, making it easier to achieve the perfect balance without resorting to additional outboard gear.

Featuring transformer-coupled mic and line inputs and outputs, the RE-51 ensures superior signal integrity with reduced noise and distortion. The inclusion of a 1/4″ Hi-Z direct injection input allows seamless connection for guitars or synthesizers, expanding your creative possibilities within a single module.

Powered by the vintage OPA 1731 operational amplifier, known for its smooth, musical character, this preamp delivers a rich, warm tone while maintaining low noise and high headroom. Stepped rotary controls provide precise, repeatable settings, critical for maintaining consistent sound across sessions.

Additional professional features include a switchable 80 Hz high-pass filter to eliminate unwanted low-frequency rumble, polarity reverse to correct phase issues, and 48-volt phantom power to support condenser microphones. An analog VU meter offers real-time level monitoring, aiding in optimal gain staging during recording.

The RE-51’s rugged chassis and gold-plated PCB internals guarantee long-term reliability in demanding studio environments. Compactly designed as a double-wide 500 Series module, it integrates easily into compatible racks, providing a versatile and high-quality preamp solution without compromising rack space.

With its combination of vintage-inspired sound, versatile EQ, and comprehensive connectivity, the Lindell Audio RE-51 is a precise tool for engineers seeking warmth, clarity, and control. Its detailed tonal options and professional features make it a standout choice for any recording setup requiring high-fidelity microphone preamplification and EQ.
