Rupert Neve Designs Portico 5024 Quad Mic Preamp

ปรีแอมป์ไมค์แบบ 4 ชาแนล Neve 5024 4-channel microphone preamplifier that offers a versatile way to connect microphones, instruments, and line-level sources

Portico 5024 Quad Mic Preamp from Rupert Neve Designs is a four-channel microphone preamplifier that offers a versatile way to connect microphones, instruments, and line-level sources. Channels One and Two feature 1/4″ Hi-Z instrument inputs, and a 1/4″ THRU output to pass the connected signal to an external piece of gear. A Mid/Side decoding button enables you to control the Mid level on channel Three, and Side level on channel Four. Every channel features a Silk button, which engages circuitry that adds vintage-style warmth to the signal. There are buttons on every channel to activate phantom power, phase reverse, mute, and a high-pass filter that gives you the option to cut at 30 or 90 Hz. All of the XLR inputs are transformer-balanced, and its balanced XLR outputs are transformer-coupled.

Every channel features custom transformers and class-A circuitry 0 to 72 dB Gain knobs and -6 to +6 dB Trim knobs on every channel. When the Gain knobs are set at 0 dB and the phantom is turned off, the 5024 can handle signals of +25 dBu without the need for pads, and act as line-level inputs with an impedance of 10k ohms. Eight-segment LED meters on every channel.Ground Lift buttons on channels One and Two.

  • 4-Channel Microphone Preamplifier
  • Silk Circuit Adds Vintage-Style Warmth
  • Built-In Mid/Side Decoding
  • Two 1/4″ Hi-Z Inputs
  • 48V, Phase, Mutes and High-Pass Filters
  • Class-A Circuitry

Features

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
