Yamaha's audio engineers have designed the new P-Series Power Amplifiers as perfect mates to the popular Club Series loudspeakers. To achieve this, they provided them with big power output that matches the power handling capabilities of the Club Series Speakers, and equipped them with YS Processing (Yamaha Speaker Processing) to deliver a signal that is tuned to the needs of these loudspeakers.
