Manley Force Quad Mic Preamp uses a topology based on Manley’s CORE mic pre section. It sports the same input level control and switch arrangement (minus one mic/line input). It also borrows the CORE’s mic input transformer and 12AX7 vacuum tube gain stage. The main technical difference between the two units is the MOSFET White Follower, new to Manley. It also employs the same Entrodev switched mode PSU as the CORE.
