The ST-PA2 from RDL is a professional-quality utility amplifier with a single input and two outputs. All connections are made via screw terminals. The first output delivers 2W RMS of power to an 8 Ohm speaker, while the second output is designed to drive 600 Ohm transformers. This makes the unit great for music-on-hold systems, which may have either 8 or 600 Ohm inputs. Both outputs may be used simultaneously if desired.
