The Rupert Neve Designs Portico 5017 DI/Pre/Comp Mobile Channel with Variphase Control is designed for studio recording, live recording, and live performance applications. This portable combination preamplifier and direct box is encased in a rugged chassis and features two channel operation, variphase control, silk control, single-knob compression and the ability to blend both microphone and instrument channels.
The front panel of the chassis features a 1/4" instrument input as well as a 1/4" Thru for connecting to an instrument amplifier. The instrument gain knob allows you to control the DI signal level from 0 to 30 dB and the microphone gain knob provides up to 66 dB of gain in 6 dB increments. A rear panel phantom power switch enables use with condenser microphones and a high pass filter button reduces signals below 80 Hz by 12 dB/octave to remove building rumble and other environmental noise. A phase invert button reverses the polarity of the microphone input.
The compressor features an adjustable threshold between -20 and +10 with a fixed ratio of 1:2 and an adjustable time attack and release time constant from standard to fast via an internal jumper. A second internal jumper allows the compressor to be assigned to the DI chain.
The variphase button and phase sweep knob allow you to incrementally adjust the phase angle of the two sources for aligning sources such as overhead and drum mics or the direct and amplified signals from a bass guitar and bass cabinet. The middle blend button allows you to mix the DI and Mic signals together, while the silk button adds nostalgic warmth and presence to both outputs.
The back of the unit features an XLR-3F mic input, a 1/4" mic output, a XLR-3F line ouptut, a +48V phantom power switch, a ground lift switch, and a 12 VDC power button.
