Universal Microphone Preamp Controller (UMPC) is a modular system consisting of the Front Panel controller, MIDI Remote, and Meter Bridge controller. Its primary purpose is to provide an intuitive yet feature-rich user interface for currently available digitally controlled microphone preamp ICs, such as THAT5171, THAT5173, PGA2500, PGA2505, and other custom solutions that are in the works at Innersonix. Another objective of the UMPC is to enable remote control of the above chips via MIDI or TCP/IP networks.
UMPC v1.0 currently supports THAT5171 digital preamp controller. Compatibility with THAT5173, PGA2500, and PGA2505 is underway.
Make gain changes on available channels in tandem. Relative gain positions remain even when any of the grouped channels reaches its top or bottom gain limits, allowing for greater flexibility than conventional “limit grouping” behavior. Only gain changes can be grouped, while GPIO states always remain separate.
Selective GPIO Recall
Recall only the button states you need and reset the rest to defaults at power up. This is a great safety feature to use with phantom power sensitive mics. Also the 4th button can be selected to act as a GROUP control or a hardware GPIO3 switch.
User accessible settings menu allows you to specify number of channels in the system, adjust for custom output stage gain offset, memorize selective functions of the preamp upon power off, specify button behavior, and more!
Customize The Look
The PCB supports two sizes of 7-segment display – 0.56″ and 0.80″. The choice of illuminated tactile buttons between Omron B3W-9000 and MEC 3F series, along with a multitude of LED color combinations can create a unique look of your gear with minimum effort.
