About RDL ST-PA6

The ST-PA6 represents the second generation of 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, equalization control and an 8 Ohms output.

The output is designed to deliver a clean 6 watts RMS into an 8 Ohms speaker. Each input is a balanced bridge, with the two inputs actively 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.
