POWER AMPLIFIER Owner’s Manual E
• Explanation of Graphical Symbols The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
Precautions — For safe operation — WARNING ● Installation ● ● ● ● ● Connect this unit’s power cord only to an AC outlet of the type stated in this Owner’s Manual or as marked on the unit. Failure to do so is a fire and electrical shock hazard. Do not allow water to enter this unit or allow the unit to become wet. Fire or electrical shock may result. Do not place a container with liquid or small metal objects on top of this unit.
— For correct operation — Connector pin assignments ● XLR-type connectors are wired as follows Pin 1: ground; Pin 2: hot (+); Pin 3: cold (–). Interference from Cell Phones ● Use of a mobile phone near this unit may induce noise. If noise occurs, move the phone further from the unit. Always turn the power off when the amplifier is not in use. Illustrations in this manual are for explanatory purposes only, and may not match the actual appearance of the product during operation.
Introduction Thank you for your purchase of the YAMAHA P7000S, P5000S, 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.
Controls and Functions ■ Front Panel 2 8 1 4 3 57 6 1 POWER switch and indicator 8 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. Press to toggle the power on or off. 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).

4 STEREO/PARALLEL/BRIDGE switch Use this switch to select the operating mode. • STEREO mode Channels A and B operate independently (as with a conventional stereo amplifier). The Channel A input goes to the Channel A output jacks, and the Channel B input goes to the Channel B output jacks. • PARALLEL mode The Channel A input signal is output through both the Channel A and Channel B output jacks. The Channel B input jacks do not function. Channel A and B volumes can be independently adjusted.
Speaker Connections ■ Speaker impedance Speakers can be connected to the amplifier as shown below. Note that speaker impedance will vary according to the connection method and the number of speakers. Please be sure that your speakers’ impedance is not less than the relevant minimum value indicated below.
■ Wiring 5-way binding post Speakon connector (1) Turn off the POWER switch. (2) Remove the cover attachment screws and remove the protective cover from the speaker terminals. (1) Turn off the POWER switch. (2) Insert the Neutrik NL4FC plugs into the Speakon connector on the rear of the amplifier, and turn clockwise to lock.
Rack Mounting Mounting in a standard EIA rack If you are mounting multiple power amplifiers in a rack, be sure to install ventilation panel(s) as shown below. Also be sure to use metal brackets (one on each side) to support the rear of each amplifer. Note: EIA stands for Electronic Industries Alliance. Ventilation panel(s) Use 1U-size blank panel(s). 44 480 Unit: mm If mounting up to four amplifiers in an open-backed rack Install a ventilation panel as shown below.
