Select this option if you intend to use a single mic input transformer for both mic and line input levels. This switch is fabricated similarly to the Neve 1063 specification for the 283AV amplifier. Also included are externally mounted 18K, 1.5K resistors and 100uF/25V capacitor for complete installation (see wiring instructions).
