You Need The ST-PA2!
The 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 or removable mounting nearly anywhere or
it may be used with RDL’s racking accessories. The ST-PA2 gives you the advantages of a utility
amplifier with the added convenience of STICK-ONs!
APPLICATION: The ST-PA2 represents the second-generation in RDL’s 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!
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 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.
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 either 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 Ω audio lines or multiple equipment inputs. For these
applications, see the STA-1 (stereo), the STA-1M (mono), or the ST-DA3 (distributed). If balanced audio
input is required, see the ST-PA6 audio power amplifier.
Wherever an audio amplifier is needed, the ST-PA2 is the ideal choice. Use the ST-PA2 combined with
other RDL RACK-UP
audio/video system.
