Radio Design Labs ST-PA2

Utility Audio Amplifier - 2 Watt

The ST-PA2 features a single unbalanced audio input a gain control and two outputs. The first output is designed to deliver a clean 2 watts RMS into an 8 Ω speaker. The second output is intended to drive 600 Ω transformers typically on equipment inputs. This makes the ST-PA2 uniquely suited to applications such as music-on-hold inputs on telephone systems which may have either 8 Ω or 600 Ω inputs. If desired both outputs may be used at the same time.

• 2 Watts RMS into 8 Ω
• +12 dBu Into 600 Ω
