These P-series amplifiers fully incorporate Yamaha's renown technological expertise, and offer high reliability, rock-solid stability, and superb acoustic characteristics--all in a trim, 2U-sized package. Features · With two types of input jacks (balanced XLR and balanced phone) and three types of output jacks (Speakon, 5-way binding post, and phone), the P series is suitable for a wide variety of applications and installed systems. · The unit offers three operating modes: STEREO (where Channels A and B operate independently), PARALLEL (where the unit outputs a mono source through twin amplifier systems), and BRIDGE (where the unit operates as a single high-power amp). The POWER indicator lights up green when the power is ON. 2 TEMP indicator Lights up red if the heat sink temperature exceeds 85°C (185°F). How to install the security cover (1) Use the supplied hex wrench to remove the four attachment screws from the amplifier. (2) Adjust the security cover to the position of screw holes. Fasten it into place using the same screws. 3 PROTECTION indicator Lights up red to indicate that protection is in effect. Specifically, lights up if the heat sink overheats, or if a DC voltage is detected at the amplifier outputs. Also lights up for about three seconds at time of power-on, as the amp gets ready to operate. To provide protection, the unit will not output any sound from the speakers while this indicator is lit up. When start-up is completed or the problem is corrected, the indicator goes off and normal operation resumes. 4 CLIP indicator Lights up red when the output signal distortion on the corresponding channel rises above 1%--indicating that "clipping" has occurred because the signal level is too high. 7 indicator Lights up yellow if the YS PROCESSING switch on the rear panel is set ON. (See page 7. ) 8 Air intakes The amplifier uses forced-air cooling. The cooling fans draw air in from the front and exhaust it through the rear. Please be sure that you do not block the air intakes or exhaust vents. NOTE: The fans do not come on at initial power-on, but will switch on automatically when the temperature of the heat sink rises above 50°C (122°F). [. . . ] the speaker system.
