Question about Yamaha P2500S Amplifier
I connected an MP3 player to the 1/4" inputs with a stereo splitter cable. I then connected 2 6 metre 1/4" plugs to both the output sockets, turned the amp on and started playing an MP3. Now, when i turn the knobs on the front (the -dB ones) to the right, the "signal" LEDs flicker in time with the music. So far so good. I then connected an oscilloscope to the other leads from the output 1/4" jacks, and got no signal on the scope! Why? Is my amp broken or am i retarded? I'm planning on setting up a large stereo system for parties etc, and i want this thing working to drink some full range speakers. :( HALP NAO!!!xx
Make sure you use the sleeve as ground reference on the 1/4" connector then check that aginst the ring and or tip and then you should see something on the oscilloscope. Let me know if that works. Have you tried hooking up some speakers? We can live chat if that help you any. Let me know Guru Jay

Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input. Get a cable like the one described here:
and connect it into any available analog input EXCEPT "Phono". Turn the MP3 player volume up.
