The Rodec M‑501 Preamp is a high‑performance 500‑series module combining a discrete microphone preamp with a versatile 3‑band EQ section, designed for premium sound quality and tonal adaptability in professional recording, mixing and production. As Rodec's first 500‑series discrete preamp/EQ, it takes your console to a new level, spanning 50 years of sound colouring with customizable pluggable opamps and analog heritage.
With up to 70dB of gain, the M‑501 handles everything from delicate ribbon mics to synths and hot line sources. A 20dB pad switch provides extra control for high‑output signals, while 48V phantom power ensures compatibility with condenser microphones. The Hi‑Z switch makes it suitable for instruments, and the phase switch offers maximum flexibility for tracking and mixing. The LED gain indication system ensures precise level setting, while an output attenuation knob allows you to push the opamps and transformers for sonic color without overdriving downstream gear.
 
The bypassable EQ section honors Rodec's analog heritage while embracing present‑day precision. The High and Low bands are lifted from the iconic 1986 MX‑18, refined with ±15dB of boost/cut at 10kHz high shelf and 100Hz low shelf. Center stage is an all‑new parametric mid band, with a switchable Q for either tight surgical cuts or wide expressive sweeps. Two 2 x Lundahl transformers and 2 discrete 6‑pin socketed switchable opamps (vintage opamp on input for warm harmonic color, modern opamp on output for punch and clarity) deliver warmth, clarity and musicality in the signal path.
 
For recording engineers, producers and musicians seeking a 500‑series discrete mic preamp with 70dB gain, 3‑band EQ, pluggable opamps, Lundahl transformers and bypassable EQ, the Rodec M‑501 is an essential tool for versatile sound colouring and professional tracking.
