The 12-150 was a 150-watt amplifier, known for its clear and powerful sound. John was impressed by its specifications, which he had researched beforehand: 150 watts of clean power, a frequency response of 20 Hz to 20 kHz, and a signal-to-noise ratio of 90 dB. He read in the manual, which he found on a nearby shelf, that the amplifier featured a built-in protection circuit to prevent overheating and damage to the speakers.
