The OMNITRONIC PAA-120 is a 120 W RMS PA power amplifier for 100 V and 70 V public address systems, as well as 4–16 ohm loads. It provides one mono line input via XLR or 6.3 mm jack, a feed-through line output via XLR or 6.3 mm jack, master level control, and status LEDs for power, level, clip, and fault. The Class AB amplifier is housed in a 2 U, 19-inch rack-mount enclosure and uses fan cooling with overheat, overload, short-circuit, and DC-voltage protection.
