A-PRE has been developed to guarantee the best possible performance from Schertler’s flagship A-DYN universal sensor.

The preamp’s low impedance CLASS-A electronics guarantee a high quality signal suitable for use in a range of pro audio applications.

Practical, on-body controls including 3-step gain, roll-off filter and a phase switch for dealing with feedback, enable quick and easy adjustments in order to achieve the desired sound.

A-PRE is powered through regular 48V phantom power.
