Consonance

pm-8MM & MC Phono Stage

Direct: $690

In the PM8 each preamplifier is independently configurable via a series of DIP switches that control gain and resistance. An additional DIP switch acts as a "rumble filter" to allow you to limit low-frequency response to 2Hz or 20Hz. Three DIP switches allow loading to be adjusted from 24 ohms to 1k ohm for moving-coil (MC) cartridges; and, for moving-magnet (MM) types, 47k ohms in unbalanced mode . There are switch positions for values of 24,130,150, 1k, and 47k ohms.
Capacitance adjustment for MMs is more limited: 100pF . A Three-switch DIP-switch array offers gains of 80,150,775,850,1300,1400,1900,2000 times.

The heart of the PM8 is a super-quiet Analogue Devices microphone preamp based on op-amps. After the adjustable linear gain stage, the signal passes through a passive low-pass RIAA filter and the low-frequency cutoff switch, followed by active RIAA equalisation. The low-impedance unbalanced signal can then be output directly.
