Manley Mono Mic Preamp

Product Description

The preamp that led the tube audio resurgence!

Big, open, alive, and totally tube!

The GAIN control changes the amount of negative feedback deployed, delivering tonal textures from richly warm to blindingly fast. Manley Iron on the transformer-coupled balanced I/O keeps it agile and beefy.

  • Operating mains voltage: Units are purpose built for original destination country’s mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage. 120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate.
