With super-high sensitivity and truly massive sound pressure handling capabilities, no source is too loud (or too quiet) for the RNT. After the capsule, the signal hits the first amplification stage in the RNT, based around a hand-selected low-noise 12AU7 tube located just behind the vents on the rear of the mic. After the tube circuit in the microphone body, the signal continues on to the outboard high-voltage power supply. On this floor box, the microphone's polar pattern is selectable via a 9-position rotary switch that moves from omnidirectional to cardioid to figure-8, with three extra steps in between each. This allows maximum versatility for any recording situation. The high-pass filter can also be switched in to 40 Hz or 80 Hz to help tame any unwanted low frequencies if necessary. Within the floor box are custom discrete class-A op-amps developed by the team at Rupert Neve Designs, which act as a buffer between the mic and the preamplifier. The gain of the RNT's floor box amplification circuit can be set at 0dB, -12dB (for very loud sources), or +12dB, and provides a staggering amount of headroom. The RNT includes the same custom-designed and easy-to-use shockmount as its sibling, the RNR1, which is essential in use to reduce the unwanted effects of vibration or knocks to the supporting microphone stand. Additionally, the matte black finish means the mic remains unobtrusive and doesn't draw any unnecessary attention to itself under harsh stage or studio lighting.
