Rupert Neve Designs 511 500 Series Microphone Preamp
The Rupert Neve Designs Portico 511 is a single-channel microphone preamplifier that implements all the coveted features and usability of a larger Portico outboard rack unit into the 500-series format. The module boasts Rupert Neve’s signature Silk button, for added harmonics that result in a characteristically vintage tone reminiscent of its manufacturer’s early designs.While the 511 is advertised as a microphone preamplifier, it does not always have to be used in this way. Setting the gain knob at 0dB enables the module to accept line-level signals.
Additionally, the 511 can power condenser miss and active DI boxes via Phantom Power, which can be activated simply by pushing the corresponding button.
In terms of processing, the 511 features a variable high-pass filter that sweeps between 20-250 Hz. There’s also an eight-segment LED meter for effectively monitoring the output.
