The Rupert Neve Designs Portico 5024 stands as a rackmounted 4-channel microphone preamplifier, drawing its circuitry inspiration from the Portico 5012 module. Featuring a built-in power supply compatible with standard IEC cables, the 5024 includes a variable high-pass filter, mute control, and RND's "Silk" function for enhanced harmonics. Additionally, Channels 3 and 4 offer the flexibility of being switched for Mid-Side decoding, where channel 3 manages the Mid signal, and channel 4 handles the Side signal.

MIC GAIN

A 12-way precision rotary switch controls gain from 0 to 66 dB in 6 dB steps.

TRIM

Continuously variable +/-6 dB level control.

PHANTOM POWER

Provides 48V phantom power to microphones.

POLARITY

Reverses the polarity of the input signal.

MUTE

Mutes the output signal.

SILK / TEXTURE

Pushing the Silk button engages the Silk circuit, which reduces the negative feedback on the output transformer, adding harmonic content and accentuating the saturation in the mid and high frequencies – similar to the effect of Silk Red on the Shelford Channel and other RND units. With Silk engaged, the distortion characteristic and harmonic content of the unit are very reminiscent of many of Rupert’s vintage class-A designs.

LED METERS

8-segment LED peak meters showing signal level on each channel.

Engages the high-pass filter circuitry.

30Hz / 90Hz

Selects between 30Hz and 90Hz for the high-pass filter frequency.

GROUND LIFT (Ch 1 & 2 only)

Lifts the ground connection on the DI input.

THRU (Ch 1 & 2 only)

Parallel THRU output for use with an external amplifier.

DI (Ch 1 & 2 only)

Transformer-isolated high-Z direct injection input.

M/S (Ch 3 & 4 only)

Changes channels 3 & 4 from independent to Mid (Ch3) and Side (Ch4)
