According to Yamaha you use regular AC power in. You may have to buy a somewhat special AC line cord though.

Some companies are funky like that. MOst of the video game mfgs for starters.

I have a ep4000 amplifier, how can i connect to a mixer


The rule of thumb is you control your audio on the low side. That means you plug your mics, tuners, audio sources into the pre-amp and then the pre-amp into the equalizer/mixer ant finally the mixer into the power amp and the amp into the "large honkin' speakers". The inter connects on the low side (between the source, the mixer and the power amp are usually done with RCA plugs. Use a good quality set of cables to get good tight connections and solid grounding.

I have two JBL speakers each 100W and 400W(peak) connected to sony receiver 7 ch each suppoert 110W connect to Karoak with 2 microphones but to sing souunded not good. thinking to get this 250 W PA amp or...


You haven't sufficiently defined what is wrong. "Not good" is subjective. Before you shell out for different hardware you should pinpoint the problem.

The source (you, mics) and the speakers are the most obvious sources of sound quality issues. Properly functioning amplifiers operated within their limits produce effectively undetectable differences in the sound.

Feedback from the speakers to the mics will sound awful.

Source input problem


Hi Seamus377

You have a faulty input selector chip by the sound of it. First, power the amp off at the wall for 30 mins, then fire it up again to see if that resets the problem.

Hopefully that fixed the problem, if not, you may need to get a tech to look at it. The input selector chips are quite sensitive and susceptible to failure, producing the symptoms you speak of. They can be damaged also and fail at any point if subjected to a voltage spike. Here is why they fail

When outboard devices such as
  1. TV that has an outside aerial
  2. VCR with Switch Mode Power Supply
are plugged into your amp, the RCA connectors connect the center "signal" connection first, then the earth ring. Until the earth ring connects, any potential difference or stray voltage present on the earth of the connection being plugged in, can result in as much as 50volts being spiked into the input selector chip. I have seen scores of amps damaged by this.

How to avoid it

Before making any connections to your amp, FIRST
  1. Disconnect external aerials
  2. Turn off all equipment at the wall socket
  3. connect all the gear and aerial LAST
  4. fire the gear up
Good luck, hope you get it sorted out.

Question on BB2125 2 Channel Amp


Hi jgoudie

It is a signal sensing turn on unit, so will not turn on until you have supplied signal to it. Plug it into a signal source and see what it does. But unfortunately, in my experience the protection light coming on means there is a fault in the amp.

You can download the user manual for the amp from here. Click downloads in the middle of the page:)

Hi Jayne

Be sure you unlug the amp before you do anything :) If you can get the lid off, perhapd you can check to see if there are any blown fuses. See what you can find and report back to me here if you like:- )

Amp 100 Line 1 in problem


Hi JamesOBrien

That is a strange problem you have indeed. The amp switches automatically from one input to the other, with default to input 1. You say the source sound dips low, is this a source from another integrated amp, where the AMP100 is working as a zone 2 device? . Are you using it as a zone 2 amp, and plugging other devices in the zone 2 area? and lastly, are you using auto on functions? Let me know, and we may be able to figure it out for you.

If it is new, then it may be worthwhile swapping it over for another by the supplier of the amp

If you are concerned about humidity and switches, spray them with DeOxit. You can get it at Radio Shack.
