Bidirectional Active Ribbon Microphone
The NTR is an active bidirectional ribbon microphone that is built with several innovative processes and techniques.
The mic’s ribbon element is made from 1.8-micron aluminum. Although such thin material is used by many other ribbon manufacturers, Rode’s innovation is to cut the aluminum foil with a laser instead of a razor. According to Rode, blades leave rough edges on the ribbon, leading to premature wear and failure.
The foil is pressed between two gears to imprint the necessary corrugation, then tensioned by machine. We know of no other manufacturer using automation to tension ribbons.
The motor uses Neodymium (rare earth) magnets. It is shockmounted within the NTR grille to prevent mechanical noise and vibration from affecting recorded tracks.
A step-up transformer, custom wound in Rode’s facilities, amplifies the tiny signal from the ribbon motor. The transformer is coupled to active electronics, which provide impedance conversion and presumably also gain (clarification from Rode is forthcoming).
The mic’s sensitivity is high, 30mV/Pa. Passive ribbon microphones, for comparison purposes, range from 1-4mV/Pa, while most active ribbons are lower than the NTR: the Royer R-122 is rated at 14mV/Pa, while the AEA N22 is ~6mV/Pa.
Due to the high output level and active electronics, the NTR can be used with any preamp, even consumer-grade pre’s built into USB audio interfaces.
The NTR ships with the RM2 ring mount and a dust cover. It is covered by a 10-year warranty (with registration), which includes 1 free re-ribboning.
