Radio Design Labs ST-PA2
2-Watt Utility Power Amplifier

OUR PART #  STPA2


Radio Design Labs' ST-PA2 is a utility power amplifier in the convenient line of STICK-ON products from Radio Design Labs. The durable bottom adhesive permits quick, permanent mounting nearly anywhere, or use it with RDL's racking accessories. The ST-PA2 gives you the advantages of a utility amplifier with the added convenience of STICK-ONs!

The ST-PA2 represents the second-generation in RDLs breakthrough in the traditional power vs. size ratio. Present technology permits features and performance at the most economical cost ever. The ST-PA2 offers 2 Watts of power...twice the power of most utility amplifiers...for a price you would expect to pay for 1 Watt.

NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product.  Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.

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 ohm speaker. The second output is intended to drive 600 ohm transformers, typically on equipment inputs. This makes the ST-PA2 uniquely suited for applications such as music-on-hold inputs on telephone systems which may have either 8 ohm or 600 ohm inputs. If desired, both outputs may be used at the same time.

The convenience and low cost of the ST-PA2 make it the ultimate choice as a building block in many systems...from simple to complex. It may be used in combination with other STICK-ONs to form custom intercoms or talk-back systems...or can be used by itself to drive a single speaker with music or voice. For both straightforward or creative applications requiring a utility power amplifier, the ST-PA2 is the optimum choice!

NOTE: The ST-PA2 is not intended to drive long 600 ohm audio lines or multiple equipment inputs. For these applications, see STA-1 (stereo) STA-1M (mono), or ST-DA3 (distributed). If balanced audio input is required, see ST-PA6 audio power amplifier.
