Hi there. I am confused about the differences between the now discontinued LFD PA1, PA2 and PA3 power amps. Help! Thanks
The PA1, PA2 and PA2M are MOSFET power Amplifiers designed to drive the majority of loudspeakers presently available. All combine a high input sensitivity to allow the use of passive preAmplifiers if required. Although they share similar circuit topologies, the more expensive models have superior power supplies and use custom made passive components and wiring.
The PA2M is a mono version of the PA2 and utilises separate power supplies for each channel and a larger output stage for even better sound quality. This amplifier is available in either a single chassis to match the LS2 or in two separate enclosures. A balanced input version of the PA2 and PA2M can be supplied to match the LSB or any other balanced linestage.
