How does an automatic AV switch work?

Will these speakers be OK for my AV Receiver?

• Please bear with me on this. Please help, I need someone who knows about this stuff as I am confused by all the numbers. My question is a simple one, but impossible for me to work out. Will the speakers (details of which are below the AV Receiver specs) be OK for my Onkyo 606 AV Receiver with no worries about them being either under or overpowered by it? In the AV Receiver FEATURES section at the beginning of the manual it states:- 90 Watts/Channel @ 8 ohms (FTC) 140 Watts/Channel @ 6 ohms (FTC) 175 Watts/Channel @ 6 ohms (JEITA) This to me is way to confusing with all the differences, imagine how much worse it went when I got to the back of the book and read In the SPECIFICATIONS section……. Technical specifications: 90 watts minimum continuous power per channel, 8 ohm loads, 2 channels driven from 20hz to 20kHz, with a maximum total harmonic distortion 0.08% (FTC). 105 watts minimum continuous power per channel, 8 ohm loads, 2 channels driven at 1kHz, with a maximum total harmonic distortion 0.7% (FTC). 110 watts minimum continuous power per channel, 6 ohm loads, 2 channels driven at 1kHz, with a maximum total harmonic distortion 0.1% (FTC). Then it says: 7ch x 140W at 6 ohms, 1kHz, 1 channel driven (IEC) Dynamic Power 210 W (3 ohms, Front) 180 W (4 ohms, Front) 110 W (8 ohms, Front) The speakers I want are the Jamo A 102 HCS 6 set. And these are the specs and on the label in the shop it said that these speakers were 60W RMS. I imagine that the figures for the receiver are not in RMS but I need someone who knows how to make sense of this stuff. Suround speakers: System Type Full Range Closed Power (W, long/short term) 60/80 Sensitivity (dB,2.8V/1m) 86 Frequency Range (Hz) 150-15,000 Impedance (Ohm) 6 Front speakers: System Type 2-way closed shielded Power (W, long/short term) 60/80 Sensitivity (dB,2.8V/1m) 86 Frequency Range (Hz) 150-20,000 Impedance (Ohm) 6 Centre speaker: System Type 2-way closed shielded (W, long/short term) 60/80 Sensitivity (dB,2.8V/1m) 86 Frequency Range (Hz) 150-20,000 Impedance (Ohm) 6 Subwoofer: System Type Bass Reflex Power (W, long/short term) 200 Frequency Range (Hz) 38-200 Power Mode Switch Auto / On / Off Variable Phase Control 0 -180 Crossover Frequency 40 - 200 Impedance (Ohm) 22k

• Answer:

  the amp is a little bit strong for those speakers it may also be that the specs for the amp are over inflated which is often the case in AV receivers now adays...but to be sure I would never turn your amp up over 1/2 way this should ensure that you don't have problems, even if your speakers are well matched its never a good idea to turn your amp up more that 2/3 of the way up...specs have to be taken with a grain of salt as different manufactures test differently and will advertise for best results as they see fit...you also need to look at distortion levels as distortion is much more destructive than clean amplifier power...
