Introduction Thank you for your purchase of the YAMAHA P7000$, P5000$, P3500S or P2500S power amplifier. 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). + Each channel is equipped with an independent OFF/LOW CUT/SUB WOOFER switch—where LOW CUT engages a high-pass filter, and SUBWOOFER engages a low-pass filter. With LOW CUT or SUBWOOFER selected, you can adjust the cutoff frequency from 25 to 150 Hz. + Each channel has its own SIGNAL and CLIP indicators. + The PROTECTION indicator lights up—and sound output is automatically muted—whenever the units protective circuitry is operating. The TEMP indicator lights up if the unit is running hot. + Variable-speed low-noise fans ensure high reliability. This Owner’s Manual covers the four models: P7000$, P5000$, P3500$ and P2500$ power amplifiers. Please read through this manual carefully before beginning use, so that you will be able to take full advantage of the amplifier’s superlative features and enjoy trouble-free operation for years to come. After reading through the manual, please store it in a safe place.

Controls and Functions Front Panel pour aumunen P7000$ ï POWER switch and indicator Press to toggle the power on or off. The POWER indicator lights up green when the power is ON. TEMP indicator Lights up red if the heat sink temperature exceeds 85°C (85°F). PROTECTION indicator Lights up red to indicate that protection is in effect. Specifi- cally, 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. CLIP indicator Lights up red when the output signal distortion on the corre- sponding channel rises above 1%—indicating that “clipping” has occurred because the signal level is too high. SIGNAL indicator Lights up green when the corresponding channels output level exceeds 2 Vrms (equivalent to 1/2 W into an 8 Q load, or 1 W into a 4 Q load). Volume control knobs Each control knob adjusts the volume of the corresponding channel, in 31 steps from —< dB to 0 dB. NOTE: If you wish to lock in the knob settings, you can fasten the sup- plied security cover over the knobs so that the settings will not be disturbed. How to install the security cover (1) Use the supplied hex wrench to remove the four attach- ment screws from the amplifier. (2) Adjust the security cover to the position of screw holes. Fasten it into place using the same screws. "+ 0) D Processing] indicator Lights up yellow if the YS PROCESSING switch on the rear panel is set ON. (See page 7.) 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 fan speed will then vary automatically as the temperature changes.
