Professional PA speaker system, 500 W, 8 Ω
“A well-equipped stereo amplifier of high power capability. For the test setup, we combined the STA-1500A with two PAB-212MK2 systems. The results were impressive. Even with high volume levels, it provided a crisp and powerful low end bass with particularly clear transients. It delivered an open, linear and well-balanced midrange. There were no audible distortions, even when we increased volume levels and the STA-1500A had to step in occasionally. After our test with the PAB-212/MK2, we were absolutely certain that this performance could by no means be equalled. However, we still decided to connect two PAB-512/BL systems [...] The STA-1500A combined with the PAB-512/BL provided such a clear and powerful sound which would normally only be experienced when using considerably larger speaker systems.”
