All A.H. Systems Preamplifiers come with a 12-volt (or 15-volt) DC regulated power source. A low voltage indicator confidently allows you to power the amplifier with your own external 12-volt DC battery. This makes it a convenient choice for field measurements. See table below for amplifier specifications.
