Primare MM15: a phono board for MM cartridges made for the I15 amplifier
MM15 is an optional phono preamplifier module that is installed inside the I15 integrated amplifier, and in that model alone. It can be added whenever the owner wishes, even after buying the amplifier, and gives it an input for a turntable. The I15 MM is the same integrated with this board already fitted.
The amplification and equalisation circuit is a hybrid design, partly passive and partly active, fast and with very low noise. Primare developed it for the newest moving magnet cartridges and for moving coil cartridges with high output. The gain is 40.5 dB.
