Description
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 a 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 best-selling 5012.In addition to 72dB of gain, the 5024’s mic pres include individually selectable phase, mute, phantom power, a selectable frequency high pass filter, and the Silk circuit which yields the rich warmth and presence of the renowned classic designs. Channels 1 & 2 of the 5024 feature a high-Z input designed for instrument level sources. Channels 3 & 4 feature an M-S switch, which enables Mid-Side decoding without the use of multiple console channels.
Rupert Neve Designs Portico 5024 Features:
- SilkMuch 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 youtry it and make your own judgment.
- M-SThe 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 InputsBalanced or unbalanced Hi-Z input for instruments using the Mic Pre’s gain circuitry.
- Level Meter-30 dBu to +22 dBuWith reference to the output
- MuteCuts of the output signal post metering and pre Buss Output. Be sure to mute the outputs before engaging phantom power.
- High Pass FilterThe 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 PowerProvides 48V phantom power to microphones
