“Akai Professional MFC42 Dual Analog filter.
The fault is that the right output channel doesn’t work, either from the headphones or the main sets of outputs, so the unit can only be used in mono. Everything else is perfect, just it cannot operate in stereo which means the dual filter independent operation on the left and right channels cannot be performed as normal.
For this reason am selling as spares or repair, no returns.” Click here to search for MPCs on eBay
