Third order distortion is typically .05%, well below audibility for listening tests. The rack mount version has balanced output while the desktop unit is unbalanced with a balanced option. The frequency counter's range is from 1Hz to 99.99KHz and will accept input levels from -40dBv to +24dBv referenced to .775v. The dB meter is a wideband averaging AC voltmeter with readout in dB.
