The Rodec M501 is a high-end 500-series discrete preamp and equaliser module designed to elevate the sonic capabilities of any professional mixing console.

Customisable Sound Shaping with Premium Components

Engineers seeking ultimate tonal flexibility will appreciate the M501’s ability to shape sound through a customisable selection of pluggable opamps and a powerful EQ section. This module embodies five decades of analogue character, allowing users to infuse their recordings with anything from warm vintage saturation to pristine modern clarity. It features two high-quality Lundahl transformers, delivering the depth and harmonic richness expected from premium analogue signal paths.

Superior Gain and Dynamic Control

With an impressive 70dB of gain, the M501 ensures ample headroom and gain staging control for a wide range of microphones, from dynamic and ribbon to low-output condensers. It includes 48V phantom power for condenser microphones, a Hi-Z switch for direct instrument input, and a 20dB pad switch to accommodate high-output sources without distortion. A phase inversion switch provides correction for phase alignment issues, ensuring accurate stereo imaging and mix clarity.

Advanced Equalisation with Switchable Q

The EQ section is fully bypassable, offering users complete control over the tonal shaping process. The parametric mid-band features a switchable Q setting, allowing for both narrow and wide bandwidth adjustments, making it ideal for surgical frequency sculpting or broad tonal enhancement. This flexibility ensures precise control over the midrange, catering to the demands of both corrective and creative equalisation.

Discrete Opamp Design with Versatile Output Control

At the core of the M501 lies a pair of discrete six-pin socketed opamps, offering the ability to switch between different opamp designs for varied tonal characteristics. It comes equipped with a vintage opamp in the input stage, providing rich harmonic saturation, while the output stage utilises a contemporary opamp for a cleaner, more defined sound. An output attenuation control allows for fine-tuned level adjustments, ensuring seamless integration into any professional signal chain.

Precision Monitoring and Build Quality

An LED gain indication system provides real-time visual feedback, ensuring optimal gain staging and preventing unwanted distortion. Designed for demanding studio environments, the M501 is built with premium components and a meticulous circuit layout, guaranteeing reliability and superior audio fidelity.

By combining customisable analogue warmth, powerful gain control, and an advanced EQ section, the Rodec M501 sets a new standard for 500-series preamp and EQ modules, delivering professional-grade sonic performance in any studio setup.
