Nathan O'Neill, VP Engineering for LOUD's MG Group, told Sonic State, "We are exceedingly happy with the design from New Japan Radio. The M-80 op-amp improves both channel separation and stereo field clarity, making multi-track recordings and stereo mixdowns more realistic. Our mixer designs are never final. If there is a way to improve performance, we will always follow that path."
The M-80 op-amp is an improved version of the NJM4580, utilizing additional technology derived from NJR's flagship "MUSES" series sound op-amps. Aside from increased performance specs, the M-80 op-amp also features the Mackie "Running Man" logo.
