(525W @ 1 kHz) into an 8-ohm load. It will provide 700 watts per channel from 20Hz to 20kHz. (750W @ 1 kHz) into a 4-ohm load. These ratings are “both channels driven”. It is extremely clean with a total harmonic distortion and noise rating of ≤ 0.1%. A unique YSProcessing circuit provides optimum performance when used with the Yamaha Club series loudspeakers. The P5000S also uses Yamaha’s patented EEEngine circuitry to reduce power consumption and heat. Input connectors are both XLR and 1/4” balanced. There are switchable high or low pass filters for both input channels, with continuously variable from 25Hz-150Hz. Outputs are Speakonâ, high current ¼" or 5-way binding posts. The P5000S weighs 25 lbs. Covered by a 3-year warranty; the P5000S is underwriters laboratory (UL). listed. | | | Features: | |

great sound with a few issuesOct 18, 2011
By BanjoGuy
First let me say I have 100 mics, 50 speakers, and 30 amps for Pro Sound, DJ and PA rentals and been doing pro sound for almost 50 years. 75% of all my equipment is Electro-voice and have never been let down by an EV mic, amp, mixer or speaker. I have been let down big time during perfomances by Mackie, Carvin, Crown, Peavey, Community, etc.
There are times (mostly out of town gigs) where the situation changes and I'm forced to buy equipment in an emergency, and if the local dealer does'nt stock Electro-voice, I take whatever is available. That's how I ended up with two Yamaha P5000s amps. (Yamaha is my second choice after Electro-voice.)
If you don't put too much emphasis on these first three cons, these amps may be ideal for you.
Con #1. The speaker outputs are both speakon and 1/4 jacks which at first seems to be a good thing. However,
the 1/4 jacks are not true "jacks" as we know them. They are a plastic barrels mounted on a printed circuit board. If you,
a guest, or a waiter/waitress gets tangled in the speaker cord, these plastic tubes break very easily.
This has happened to once-in-a-lifetime renters on several of my other Yamaha amps (EMX 88S, EMX860ST).
Con #2 The power cord is hard wired instead of the typical computer power cord. Again at first, looks like a good a idea until you realize it's an 18 gauge cord. UL does'nt allow 18 gauge extension cords anymore because of
fires when people use them for heaters, toasters, hair dryers etc.
Even all of my microphone cords are 20 gauge which is the next step up from 18 gauge
For an extra 25 cents, Yamaha could have
used a 14 gauge cord (or 16 gauge at the minimum). I will replace the 18ga cord with a 14ga cord when the
warranty expires. (I assume the Yamaha engineers have never been at the end of four hundred feet of
electrical extensions begging for every volt & ampere, or been plugged into a generator also operating
a moon bounce, beer truck, and tent heater only having 90 volts available.)
Con #3 The extra large front handles are eye appealing, until you try to mount the amp in a road case. The handles
stick out way to far and you can't use the cover of the road case. The handles cannot easily be removed
without violating the warranty. Looks like you have to disassemble the top, bottom and front to gain access
to the screws holding the handles. A bum design.
Pro #1 The reason Yamaha is my second choice after EV is the design of their limiter. I have other non-EV
and non-Yamaha amps that leave an audible drop out when the limiter activates. It may only be tenths of
a second, but the audience can detect the drop out. The P5000S limiters act flawlessly. There is no
interupption in the music, no pressure wave sent out when they release, and you can't really tell
when the limiters activate other than by looking at the signal leds.
Pro #2 The mode switch on the rear which allows you to operate CHAN A full range and CHAN B for subs, or
CHAN A&B for mains, or CHAN A&B for subs with a frequency control which allows you to control the
signal sent to the subs.
Pro #3 Recessed and detented front gain controls which are protected from damage and quite accurate
when setting CHAN A&B to the same output level.
Pro #4 Twin fans, pure sound, impeccable inside wiring, switching power supply (no massive toroidal transformers),
relativeley light weight per watt.
Pro #5 Removable clear plastic anti-tampering windows which cover the front gain controls when you want to set
a certain level and don't want anyone monkeying with the knobs. Easliy removed with a supplied
wrench.
Pro #6 A seemingly minor point, but they include a cover for the rear 5-way binding post/banana jack panel.
May not seem important until you understand where once-in-a-lifetime renters try to plug things in.
Conclusion - in my opinion, if Yamaha spent $2.00 for a better power cord, Switchcraft speaker jacks instead of
plastic tubes, and easily removable handles, I would give the P5000S a glowing perfect rating.
But until then, I say 3.0 mostly because of potential catastrophic failure of the 1/4 plastic speaker jacks (tubes/barrels)
Renters always get 1/4 cables anymore. They don't know how to use speakons. I've gotten
amps back with two 50 foot cables wrapped around the amp because they forgot how to remove the speakon
connectors.
I'll be modifying both amps as soon as the warranty expires to change the power cord, remove the
handles, and install metal Switchcraft speaker jacks.
