Radio Design Labs ST-PA6

The ST-PA6 is a utility power amplifier in the convenient line of STICK-ON products from Radio Design Labs. The durable permanent or detatchable bottom adhesive provided with the ST-PA6 permits quick, permanent mounting nearly anywhere, or use it with RDL's racking accessories. The ST-PA6 gives you the advantages of a quality audio power amplifier with the added convenience of STICK-ONs!

The ST-PA6 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-PA6 offers 6 Watts of power for a price you would expect to pay for 3 Watts!

The ST-PA6 features two balanced audio inputs...a gain control...and an 8 Ohm output. The output is designed to deliver a clean 6 Watts RMS signal into an 8 Ohm speaker. Each input is a balanced bridge, with the two inputs mixed equally. This is particularly useful for monitoring a stereo line. The output stage features protection against short-circuits and thermal overload. The output protection automatically resets once the condition is removed, making fuse protection unnecessary!

The compact design and low cost of the ST-PA6 allow using it to individually drive each speaker in many installations. Since most applications using low speaker power levels are running music at a background level, speaker inefficiencies tend to produce a thi" sound lacking in low frequencies. The traditional approach to correct this, if at all, has been to cut the high frequency response producing an apparent increase in bass. The ST-PA6 now offers actual equalization...permitting the installer to set the low frequency boost, rather than a high-frequency cut. As reproduction quality has improved, listeners have become more sophisticated...and crisp, high-frequency response is expected in a quality sound system. With the ST-PA6, this flexibility is now available for the cost of a typical utility amplifier!
