need help with pioneer 1015tx

[cheapskete OCer]

im having trouble getting this reciever set up right .....im using cheap satt speakers ...they are sharp speakers 100w max and they say atleast 4ohm....how do i change the ohms on the reciever.....i also bought a klipsch synergy 420w 10inch sub ...that sounds awsome ...but there just seems to be to much of the highs coming out of the satt spkrs ...i know its because i have them set as small on the reciever but i need a little mid coming out of those some stuff just sounds stupid like that....also there are 2 different surround speaker inputs on the back ..there is surruond l and r ...and then there is surround back l and r ...i only have 5 satt spkrs so i put the rears on the surround inputs not the rear surround inputs ...is that right .....thanks

The 1015 is not meant to run 4 ohm speakers. There are only 6 or 8 Ohm options. That said, if you don't crank it up, it should be OK. Watch that the receiver doesn't get too get real hot and turn off.

Have you run the MCACC setup with the microphone? This should have helped set the speaker distances and the EQ. What is the frequency range of your satt speakers? The satts may not be able to provide any midrange.

Setting the speakers to large will throw all the low end sound at your front satts. No sub will be used. Again the satts may not be able to handle any of the mid & low end. If your front speakers contain woofers, mids and a tweeter then you can set the fronts to large. If your calling them satts then I'll assume these speakers are small.

If your only running a 5.1 speaker system then you connect to the surround L & R. The rear surrounds are for the # 6 and #7 speakers.

yes i have ran the setup ...and they are small speakers....what is the diff in 4ohm spkrs and 6-8 ohm

If they say 4 ohms at least they are probably 6-8 ohms nominal, but could dip to 4 ohms minimum depending on the frequencies. Most receivers are designed for 6-8 ohms speakers. Everything being equal, a 4 ohm speaker would draw more current from the amplifier. Cheap Sat speakers generally don't draw much current so your 1015 should do fine. Instead of trying to get the small sats (it really depends on how small and how cheap they are) to reproduce the lower middle range, try setting the crossover to 150 Hz or even higher and let the subwoofer help a little more. The auto set up may have set the crossover too low. A higher crossover would make the lower mid frequencies more localized. It is a comprise, either that, or to live with that thinner sound from the sats. You may also try to position the sats a little closer to the wall and the corners if possible.

what about the low pass freq on the sub ...i have it set at 80 right now...i have no idea what thats for...i just realized i have a set of old fisher floor speakers they are 8 ohms 10-100watt would i benefit fromn running these up front ...would it sound better ...with speakers that dont match..being the sharps are 4 ohm and the fishers are 8ohm.....

You want the xover on the sub set as high as it will go because you are using the xover in the receiver. Take Peng's advice and make sure the xover on the receiver is set to 120-150Hz (if they are truly small satellites, 80 Hz will be too low).

If you set the xover on the receiver to say 150 Hz and the sub is set at 80 Hz, you will have a hole in the frequency response between 80 and 150 because the receiver will send the sub 150 Hz and below but the sub will only amplify 80 Hz and below.
