Rupert Neve Designs Portico 5024 Quad Microphone Preamplifier

Incorporating four channels of renowned preamplification, independent silk controls, two channels of DI inputs, and an M-S Decoder into a 1U enclosure, the 5024 is workhorse equipped to enhance the front end performance of any digital or analogue recording system. Each channel of the Portico 5024 is based around the custom transformers and class-A circuitry found in the 5012.

• Silk - Much could be written about this feature, suffice to say, that it gives a subtle option to enhance sound quality in the direction of vintage modules. The Silk button reduces negative feedback and adjusts the frequency spectrum to provide a very sweet and musical performance. We suggest you try it and make your own judgment.
• M-S - The M-S button engages Mid-Side decoding on channels 3 & 4. Channel 3 level controls the mid signal, and channel 4 level controls the side signal.
• Instrument Inputs - Balanced or unbalanced Hi-Z input for instruments using the Mic Pre's gain circuitry.
• Level Meter - -30 dBu to +22 dBu With reference to the output
• Mute - Cuts of the output signal post metering and pre Buss Output. Be sure to mute the outputs before engaging phantom power.
• High Pass Filter - The High pass filter is a valuable aid in any signal chain but particularly so in a microphone preamplifier. Signals below 30 or 90 Hz can be attenuated at 12dB / Octave, leaving the range above this unaffected. This gets rid of building rumble, air handling motor hum etc.
• Phantom Power - Provides 48V phantom power to microphones
• Phase Inverts - Flips the phase of an incoming source 180 degrees
