Circuit Protection
I purchased a monster cable SS-6 speaker selector and according to the
manual it has " High Current Amplifier Protection circuitry: When engaged, this impedance matched circuitry maximizes high power amplifier performance and allows you to safely use multiple speaker pairs simultaneously without overloading or damaging your amplifier." My question is why would you ever turn this off? Is there any harm leaving it always enabled? Thanks john |

Well, from the sound of it, it's the usual marketing ******** to be expected from monster. http://www.monstercable.com/lit/Spea...d_6_Manual.pdf For starters, you actually don't want your speakers to be 'impedance matched' ! How would you switch it off anyway ? Graham |

I'm surprised Monster didn't think up a clever acronym and trademark it. Current Rich Amplifier Protection? S. I wonder if they include any TCPSPD's in their products?

Anything from monster is going to be mostly marketing and way short on
actual proven technology. It's probably a resistor network of some sort and you'd want to turn it off if you were running any serious power through it. More than likely the resistors are rated all that high for wattage disipation. wrote in message ...

There is a button to turn it on/off. So are you guys saying thats its
basically a useless feature Monster adds to make it look better? Then is it better to leave it always enables or always disabled when using multiple speakers?

If you are using multiple 8 ohm speakers then when two are connected they are probably parallel. That would be 4 ohms. Practically any decent amp is going to handle a 4 ohm load. Yes, you could drive it into clipping easier with a 4 ohm load than an 8 ohm load. What's the amp and are you expecting periods where you push some of the limitations? Above 2 speakers then the unit is probably combining them both parallel and serial to achieve some load between 4 and 8. Often damage comes from driving amps into clipping where you end up with larger periods of straight dc voltage in the output. Bad for stuff. Solid state amps are directly connected to the load so it is easier to overload an amp with 4 ohms than it is 8. If your amp has some sort of protection circuitry then that would be all the more reason not to use the switch. The switch is probably adding resistance. That's pretty much a waste as any energy used up by the resistors is not being turned into sound. |

Its not to late to return it, but I did not buy it for the circuit
protection. The salesman at the electronics store said it was one of the few that use parallel vs serial wiring. In fact he had a Niles selector which was more expensive and he steered me towards the Monster. Thanks John On May 1, 2:34 pm, "Earl Kiosterud" wrote: wrote in message ...

Presenting the same impedance to the amplifier as a single (pair of) speaker(s) is desirable. If it is not achievable (you'd need an autoformer or more complex circuit than a resistor network) then series would be preferable to parallel. Two parallel loads have less impedance than either one alone. Amps can drive higher (series) impedance loads without problem, you'll just get reduced power output. Driving a LOWER impedance can place too much load on the output devices causing them to fail. The lower impedance just pulls too much current. Most solid state amps can easily handle 4-ohm loads, and many of the better ones can do 2 ohms. Cheaper amps most definitely can't. The low-end electronics market dictates that power ratings are exaggerated, and many circuits are designed with very little safety margin. Whereas you might get away with driving 8 ohms at full power, if you try 4 ohms you might get to see a bit of the magic smoke escape. If your receiver has terminals for two sets of speakers, then it SHOULD be designed to drive 4 ohms or even a bit lower without trouble. The Niles is more expensive in this case because it a better unit. |

If it does what you need and it was the best price then it is fine. They
are all similar inside and use switches to combine the speakers in various parallel and serial arrangements to achieve something between 4 and 8 ohms. They do expect that you are using 8 ohm speakers so if you use 4 ohm ones then you may sometimes end up with a 2 ohm load and than's a bit low. My amp protection circuits kick in sometimes when I run 2 ohms. wrote in message ... Its not to late to return it, but I did not buy it for the circuit protection.

I didn't properly emphasize here that the very most important part of a multi-zone installation is to set the gains properly and then to armor the settings against user attack. If you can guarantee that nobody else will ever, ever, cross your heart and hope to die never, have access to the gain adjustments, then you have nothing to worry about. Otherwise...
