Setting Impedance and Using A Speaker Selector
I need a little help understanding impedance settings from the
experts.Im going to be using a Monster Cable 6 speaker selector box (SS-6) with 4pr of 8ohm speakers. Each pr of speakers will have its own volume control and not all speakers will be on all the time. My amp is 8ohms. From all the information Ive read I should set the impedance on the volume controls to 4x, but nothing factors in the speaker selector. What if only 1pr of speakers is "active", should the impedance be set at 1x? Does the speaker selector have anything to do with my impedance setting? Thanks John |

What volume controls? What does the impedance selector on these volume controls do? Does it switch in even more series resistors (which will dissipate even more audio signal)? Feeding a large number of switched speakers plus volume controls from a single amplifier at 8 ohms is a very tricky proposition and something that professionals generally avoid for that reason. Unless you are running a low-level ("background music") system, I would recommend against your proposed configuration. The prefered method of feeding multiple speakers such as you are proposing is to use the "constant voltage" (aka. "70V system") scheme.

Since we don't know what your "volume control" is, nobody can really answer that. |

Setting Impedance and Using A Speaker Selector
I have a Pioneer home theater receiver rated @ 100w. Its always in
use, I pipe my TV audio throught it as well as my dvd player. It's also my main radio. I'm looking to add three pair of out door deck speakers using the monster speaker selector. Each pair of speakers will have separate volume controls, I'm using Jobsite V12-AWE controls.(http://www.jobsitesystems.com/ product_result.php?prodID=V-12/AWE&recordID=12%20Step%20All %20Weather&categoryID=Volume%20Controls&catcdID=6& prdcdID=FG01119) Each volume control has Adjustable Impedance: 1x, 2x, 4x, 8x settings. From the information I have read on the internet I need to set these so the amp does not over heat. However nothing I have read mentions if a speaker selector effects impedance. One of my thoughts was that the speaker selector takes care of matching the impedance so there is no need to also worry about setting it on the volume controls. When I say from what I have read, I mean the various web sites I have found reference impedance matching on the internet.

In general I would agree to that. If your selector switch assumes an 8 ohm load, and you have 8 ohm speakers, there seems to be no reason why you should use anything other than the "X1" switch setting. Note, however the warning: "Combining IM controls with such a selector will reduce you maximum volume substantially." And even more so with such a low power amplifier. I would be uncomfortable using such a low-power amplifier if you expect "party-level" sound performance out of the deck speakers. Again, I would NOT recommend this kind of scheme. It is frought with multiple perils and seems unsuitable for any but low-level back- ground music. |

Again, unless you are only talking about low-level "background music" application. Not clear why you don't just use a portable radio on the deck? One reason would be stereo separation, and stereo separation does sound better. Its also good to keep speakers backed up and not in the face of people. This gives overall volume without being too hot to talk or listen. Portable means moving it around all the time. I don't know what music or whos listening or how loud. Portable radio might make it hard to listen to TV or other sources on the cable or satellite. greg |

Setting Impedance and Using A Speaker Selector
I saw that section of the manual, I don't know what "IM" stands for.
But the lower section of that paragraph is what caught my eye. The monster has a defeatable protection circuit, in fact you have to push in a button to tun it on. Heres a quote from Page 4 of the Jobsite manual: "Combining IM controls with such a selector will reduce your maximum volume substantially. To solve this problem, specify a speaker selector with a defeatable protection circuit (JobSite models S-4 or S-6). Then keep the protection circuit off at all times." The main reason for not just using a portable radio is as mentioned before, I run my Dish music stations outside. The other reason is that Id have to have a couple of portable radios to get the sound to where it needs to go(separate places around the exterior, not just the deck). Another thought was to not even use the speaker selector. Just run the wires from the receiver to the volume controls then to the pr of speakers. Use the volume controls to turn the sound on/off. This was actually suggested by Jobsite tech support. That had actually never occurred to me and at first I didn't like the thought of it, but now the more I think of it it may actually provide louder sounding speakers. Thanks John Did you miss the section on page 4? It is titled....

If I understand how the SS-6 works, it would be OK to set the speaker volume controls to 1X. If you had no SS6, but just ran the lines to the speakers in parallel, then you'd want to set the remote volume controls to 4X. |

Driving all the speakers all the time seems like premature death for your underpowered amplifier. Remember that turning the volume control down (and even "off") maintains the same load on the amplifier as if it were turned all the way up. PS: Please do not "top post". It is rude usenet netequitte for several reasons. |

I didn't speak to a person from Jobsite, I got a reply from tech support. From what I gather some selectors have built in protection when using multiple speakers that cant be turned off. With the Monster you have to depress a button to turn it on. I didn't even think of the continual power aspect. Just out of curiosity, if the volume control to the speakers is turned off and it maintains the same load, would it not maintain the same load even if the selector to a pair of speakers it turned off? What makes this different? thanks John |

What makes this different? Most of those remotely-located volume controls are of the "constant-load" variety and are "L-pads" or even "T-pads". They present a constant load to the amplifier to simplify system design and performance (at the expense of power) so that they can be positioned at the point of use, likely far away from the amplifier. OTOH, speaker switches are generally co-located with the amplifier and attempt to "normalize" the load on the amp as speaker loads are switched on and off. This is often done by inserting series resistors to keep the load from going too low for the amplifier to safely drive. This has the negative side- effect of dissipating the majority of the amplifier power into uselessly heating the protective series resistors. It also has the side-effect of dramatically changing the amount of sound that gets to the speakers depending on how many you have concurrently connected. This is why it is quite possible that your amplifier is under- powered for your desired use, depending on how loud you anticipate running the speakers. |

A new receiver is not an option at this point. Thanks John |

Seems like he should investigate a cleaned-up system with just one layer of passive distribution networks. IOW, just use the volume controls with impedance set at 4X. |

Thanks John As others have noted above, the amp you've got is, shall we say, less than robust when it comes to driving anything but a 4-ohm load. As far as maximum volume goes, you might be happy enough if you don't plan on driving all sets of speakers all the time. As you switch in pairs of speakers, a resistor gets added in-line to keep the impedance seen by your amp at around 8 ohms. So, lotsa heat, not much sound, keeps the amp safe. But, if you want to rock the house (or deck) you can turn on only one pair and get the full performance out of your amp for that set of speakers. If you could find reasonably efficient outdoor speakers (unlikely) then I'd say 100W might do ya' to run a couple of sets simultaneously, but the 4-1/2" or 5" drivers you're likely to see in most outdoor mountable speakers are likely to have an efficiency rating of no higher than 90db/w/m, with most being closer to 86db/w/m. Bottom line: try it and see before running out and buying a bigger amp, you might find it's plenty loud enough for you. Dave |

I know it has a button for speaker "A" and/or "B" so there would be no need for the Monster selector. I can use the volume controls and set the impedance at 2x and all should be well. The down side to this the receivers placement and trying to hook up my Dish receiver to go through this receiver as well. Thanks for all the suggestions. John |

John All kinds of links to pay or register download pdf's on Google search, for get that. Its at least 3 times the price what I paid for my Pioneer unit. I might check specs later. Oh I just found the speaker. Got a SN ratio spec, forget that spec sheet. I would believe 100 watt Fisher. You can hook up the ouputs of the Pioneer through adaptors, especially the ground loop isolators type, to feed the second amp from the first amp. If you really wanted, could also go RF wireless. If the second amp had IR remote, would be really cool. greg |

I have an OLD Fisher 1000w stereo thats been sitting in a box in the basement for years. I can use that to power the 3 pr of outside speakers. I know it has a button for speaker "A" and/or "B" so there would be no need for the Monster selector. I can use the volume controls and set the impedance at 2x and all should be well. The down side to this the receivers placement and trying to hook up my Dish receiver to go through this receiver as well. Thanks for all the suggestions. John All kinds of links to pay or register download pdf's on Google search, for get that. Its at least 3 times the price what I paid for my Pioneer unit. I might check specs later. Oh I just found the speaker. Got a SN ratio spec, forget that spec sheet. I would believe 100 watt Fisher. You can hook up the ouputs of the Pioneer through adaptors, especially the ground loop isolators type, to feed the second amp from the first amp.. If you really wanted, could also go RF wireless. If the second amp had IR remote, would be really cool. greg Greg, You are correct I think it is a 100w amp, I made a typo. It does have a remote control but the distance is pretty limited.Its at least 20yrs old. Its a plain old stereo, nothing fancy, Fisher model # 9115 and Im having trouble finding a manual on line, even the pay sites don't have one. I have a call in to fisher to see about buying one. Most of the stuff you guys have been talking about is way over my head. Can you explain what you mean by this: "You can hook up the ouputs of the Pioneer through adaptors" and the part about going RF wireless. If you meant RF wireless for the speakers I looked into that. Most of them need a power source near the speaker placement. I dont have outlets near where the speakers are. Thanks John |

Most of the stuff you guys have been talking about is way over my head. Can you explain what you mean by this: "You can hook up the ouputs of the Pioneer through adaptors" and the part about going RF wireless. You can buy car audio adaptors for speaker level to line level. Some allready have ground loop isolators. This makes a balanced line which provents hum and noise from getting into line level rca cables. You can directly attach a ground loop isolator to a speaker output. A little padding may be necessary to reduce level. http://www.crutchfield.com/S-hDBk3Oq...l-Adapter.html http://www.crutchfield.com/p_127SNI1...+loop+isolator Hope those links work. Radio Shack also sells adaptors as well as your local car audio shops, probably Best Buy. If you meant RF wireless for the speakers I looked into that. Most of them need a power source near the speaker placement. I dont have outlets near where the speakers are. No I mean RF wireless between amps. That eliminates the connection from the first amp to the second, assuming the second will be in another location. Could even be outside. Thanks John |
