Hope someone here can help me out. I have an Integra DTA 70.1 nine channel power amplifier that has an impedence switch on back but it only offers two settings. One setting is for 4ohm and the other is for 6-16ohm. I have Emotiva Airmotiv speakers for fronts and center and they are 4ohm impedence. The other speakers are rated at 8ohms so the question is can I hook these speakers together with this amp and if yes what setting should I go with? I would really appreciate any help. Thank you everyone. Stay safe. You can safely set the amplifier to the 4 ohm setting and power everything. As long as your speaker impedance is 'equal to' or 'greater than' the amplifier's impedance rating, you will be okay. There might be some volume or loudness differences between the 4 ohm and 8 ohm speakers, but you won't burn up anything. Happy listening. |

Sorry but this is actually bad advice! Leave it set to 6 to 16 ohms that switch is only there to allow the device to pass EU compliance testing. You will actually protect your amp better by leaving it on the higher level See www.youtube.com/watch?v=Ou5bO8P2Drw |

Thank you everyone. Stay safe. Those swtiches are used to protect poor amplifiers from the effects of loads they are essentially incapable of driving properly. Scanning thru 1/2 a dozen 'non-reviews' I don't see any REAL bench data, just quotes of 2 channel power.....though FTC is noted. Amp even if used as 5.1 system will NOT put out anywhere near the 2 channel claims. PS is marginal..... Use the 4 ohm setting. Consider the purchase of some substantial upgrade in amplification.....at least 5 channels worth, while leaving the remainder with the Integra. While the audioholics guys DO mention additional heat......and also the need for additional ventilation, I'm just not on board with that approach. They make note of the 'double down' idea of 8 to 4 ohm power. NO HT RECEIVER does so that I've ever heard about. The audioholics guys even mention that HT power supplies are 'shrinking' as features and such are ADDED. All BAD NEWS. A new amp SHOULD last thru several upgrade cycles which means you'll still be using it long after this piece is unfixable.... |

I disagree with your advice... partially. If you must drive lower impedance loads, then so be it.. but don't select the lower impedance. TO understand why real the links I posted.

You Know, JK, I'm going to do a flip-flop and agree with you. Sure. Leave the switch alone at the higher setting. Doesn't do anything to the output devices......
But I'd say to keep an 'open ear' for distortion while the potential for heating the amp up is quite a bit higher. The only good news is that if you are using HT speakers, they are
generally of medium to higher sensitivity AND are also not usually a 'bad', amplifier stressing load.
I'd still recommend going to better amplification for at least the L/R/C speakers IF your receiver has pre-outs. If not? You're stuck.
