The ART S8 can be used to split eight balanced low impedance microphone signals into sixteen balanced low impedance microphone signals. Each channel of the S8 provides one direct output and one transformer isolated output from a single microphone. The S8 includes a ground-lift switch on each isolated output to reduce noise due to ground loops between connected equipment. Frequency response is 20 Hz - 20 kHz. Dimensions: 531 x 178 x 89 mm.
