There's a small switch on the side labeled LP-AP-HP. Make sure it's in the LP or AP position, not HP. There's a small dial labeled FREQ; if your amp is connected to subwoofers and the switch is in the LP position, adjust the dial until it's set around 80-100.

Cant seem to get the bass bumping louder

Not sure what product you have installed but, if this is an aftermarket amplifier then, you may need to adjust the gain at the amp.

My 200hd head is not putting out the full 200 watts i have a behringer 8x10 cab and before this head used to power this cab fine now even with the volume cranked you cant even feel the bass i have...

I am not sure how you are measuring the power output to verify it is less than 200 watts. With a true RMS voltmeter you should see 28.28 volts RMS across a net speaker load of 4 ohms. If you use only one 8 ohm speaker, you will get 120 watts. If you are getting the 28 volts there is nothing wrong with the amp. You MAY have blown the speakers OR not generating much bass due to processing in an EQ. I assume you are using at least 15 inch speakers if you want to feel bass. Look up your speakers specs... you will need speakers capable of 32 Hz to feel much. With this amp your speakers should have aa total rating not less than 400 to 600 peak watts or around 300 watts RMS continuous power rating. Using a lot of high end EQ will keep the amp busy at the high end and reduce the power available at the bass end.

Hello Tech, I beg your wisdom. My keyboardist and I love the Yamaha S80 but are stumped with an operational problem. The club blues internal 039 C07 patch sends an anoying ride cymbal strike with every...

I'm not familiar with this kind of keyboard, but it is almost certainly that you have 2 parts (2 instruments) layered together. In this case a bass and a cymbal. This is a feature, not a malfunction of every multitimbral keyboard. Multitimbral means you can play more than one instrument at the same time. This is good as you can create some nice fat sounds, but put the wrong instruments together and you'll have the problem you're experiencing. My suggestion is that you read what the manual says about layering or mixing parts. There you should find instructions on how to turn one of the instruments off. You can also try to google the words "how to parts layer (or sound layer, or combine sounds) on the Yamaha S80". Good luck.

Speakers cut off when bass goes up

probably the amp going to safe or protect mode judging by the fact that you have 3 subs wired to it i would say it is not 1 ohm stable try disconnecting 1 sub and see if it still happens this will be running a 2 ohm load rather than 1 if it stops happening then you need to figure out a better wiring configuration that will work with your amp.

I need help?

id check remote signal with a test light and also if there is a High pass or Low pass filter either on the head unit's settings or the Amp's controls

if your amp or head unit has a High pass filter setting enabled that would explain no bass being sent to your speakers,

if you are using a separate crossover to send the bass signal check those settings too..

if all else fails
test another amp on your system (if it works that would discard problems with the rest of the system's output)

Amplifier wont move subs

I dont know if this will help you but start at the deck and make sure that the outputs(RCA) arent crossed over to highpass and do the same at the amp make sure that its set for lowpass- set half gain -bass boost half gain- subsonic minimum - If that doesnt help try using an i pod with an adaptor that you can play it right into the amp this is to see if you are getting signal from the deck to the amp if it doesnt work with an i pod or mp3 plugged directly into it then you may have got you a blown amp going on- good luck with that

Playing music for about 2hours and bass amp shuts down

You have maxed out the amp! if your running one 4ga. pwr wire to all your amps, it's choking. Going to Wendy's buying a frosty and sucking it thru a straw!. Your amp is starving for more Voltage and current. That amps peak output is 1200w @ 1ohm, not too shabby! Now onto the next issue: Grounding!, just as important as power! Your amp MUST be grounded properly. Don't ground it to a seatbolt or side wall of the vehicle, go directly to the floor, hopefully less than 2-3ft tops. using the same gauge wire as power. If your power is longer than 12 feet, and in most cars it is, you loose alot of voltage and current flow to the amp the longer the run, the more you loose. That's just how DC power works. What's happening to your amp is it's working itself to death and creating massive amounts of heat. "enough to cook dinner" Run a 2ga or 1ot power wire to a distribution block at the amps. Wire in your other amps, then use the stiffening cap just for the sub amp. Not a cheap answer but it will solve most of your problem. Next, set the gain on the Sub amp NO HIGHER than 1 o'clock. Beyond this, and there's no help for it, there's no more gas pedal to push!. Enjoy your system but don't kill it! Hope this helps
