Rupert Neve Designs RNDI-M Active Transformer Direct Interface

The RNDI-M brings the stunning tone & clarity of its award-winning counterparts to an even more compact and pedalboard-friendly format, with the exact same custom Rupert Neve Designs transformers and discrete FET input stage as the best-selling RNDI, RNDI-S and RNDI-8.

By streamlining its feature set and housing the electronics in a rugged & more compact chassis, the RNDI-M fits neatly into any space and will allow even more musicians and engineers to tap into the uncompromised sonic power & vibrancy of a Rupert Neve Designs DI.

• Groundbreaking Direct Tone
When class-A, discrete amplifiers meet Rupert’s custom transformers, amazing things happen. The RNDI-M contains the unique components and design knowledge that makes it worthy of the Rupert Neve name.

• Huge Headroom
Maximum input level is a massive +20.5dBu, making the RNDI-M capable of handling not only instruments but also keyboards, drum machines and even pre-recorded material.

• Rugged Solid Steel Frame
The rugged steel chassis is built to withstand the severe stresses of life on the road.

• Use a Variety of Sources
The RNDI-M has immensely consistent performance across a wide variety of sources due to its 2.2M Ohm discrete FET input stage and high headroom. The RNDI-M can be used with confidence on guitars, synths, basses, acoustic instruments, keyboards & drum machines.

• Drive Longer Lines
The low impedance transformer coupled output – below 40 ohms – is capable of driving long lines while maintaining exceptional high frequency performance.

• 1/4″ THRU Output
The THRU output can be used to maintain optimal input level to an amplifier with no signal degradation.

• Ground Lift
A Ground Lift switch is provided on the rear panel to isolate Pin 1 on the XLR balanced output from the circuit ground to help fix any potential grounding issues.

• Phantom Powered
The RNDI-M is powered by standard 48V phantom power. Power is indicated by a blue LED on the front panel.
