Mobile Mic Pre / DI / Comp
Comprised of a rugged, portable chassis with world class Portico pre-amp, compressor and DI circuits as well as two channel operation, variphase, silk and DI/mic blending capabilities, the Portico 5017 is an innovative and powerful tool for recording or live performance. In replacing the Portico 5016 Mic Pre / Variphase DI, the 5017 Mobile DPC adds single knob compression, DI / Mic Pre blending, and a go anywhere design to a well established classic.
With Portico Series custom transformers and silk mode, the Mobile DPC’s sonic signature is nothing short of legendary. It’s the 5017’s revolutionary feature set however that make it an indispensable tool for studio recording, live recording and stage performances.
Two Channel Operation
With two transformer coupled outputs, the 5017 has separate line outputs for the DI/Blend and Mic signals when the blend control is set to fully DI. The mic output is always independent.
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.
Mic gain is from 0dB to 66dB. Overall gain to restore the apparent program level
DI Gain is from 0dB to 30dB
Balanced or unbalanced Hi-Z input for instruments
High pass filter
The high pass filter is a valuable aid in any signal chain but particularly so in a microphone preamplifier. Signals below 80hz can be attenuated at a rate of 12db / octave, getting rid of building rumble, air handling motor hum etc.
Provides 48v phantom power to microphones. Controlled by a switch on the back of the unit.
Reverses the polarity of the mic input
When signals exceed the “threshold” level, the gain is reduced at a controlled 2:1 ratio, with attack and release time constants set to standard or fast depending on the internal jumper setting.
Indicators on the 5017 denote signal presence and clipping on both DI and mic signals, as well as compressor activation.
Two internal jumpers in the 5017 can be set to change the compressor from the mic channel to the di / blend channel, and to change the compressor time constant from standard to fast.
