SKU: OSD-SPW8
OSD SPW88x Zone Speaker Distribution Panel
The SPW-8 is a stereo (two channel), one input, eight output, broad frequency response, volume control distribution hub. It provides a simple solution in complex speaker installations providing an easy way to connect from two to eight volume controls and pairs of stereo speakers to a single stereo receiver/amplifier. All outputs are labeled easing both connection and troubleshooting of a system

Does anyone know if the SPW-8 speaker distribution "panel" will attach (easily and w/o special modifications) to an On-Q HT1000 home entertainment connection center? There's a blank plate on the HT1000 that seems like would be a good spot for the SPW-8. See attached picture of HT1000.
Thanks,
Mark

Hi Mark:
Here are the dimensions of the SPW-8.
Dimensions: L 3.40 in. x W 1.70 in. x H 7.00 in.
Note: it would not work for Home Theater connection being one input to 8 outputs (versus 5 or 7 channel inputs of a 5.1 or 7.1 system you would need). If you are looking for 2 channel distribution for your house, you need to use an impedance-matching volume control in each zone. The block has no protection circuitry. I hope that helps.

I have a 4 speaker selector switch now with 4 speaker pairs, but am looking to add one more pair of speakers. So either going with the connector block or the 6 speaker pair selector switch. I already am using your impedence matching vol controls on all speaker pairs. If I go with the connector block I remove the power loss associated with the selector switch protection. If I go with the selector switch I have the ability to totally shutdown speakers not in use (although with vol control turned down there is no noise). Am I gaining any protection for the amp with the selector switch setup that I do not have with the impedence matching vol control?

Hi Dan,
When you are using Impedance Matching Volume Controls along with a Speaker Selector like our ISS6 or DSM6, the rule of thumb is to let the Volume Controls do all the protection while making sure that the protection switch (on the front of the ISS6 and on the back of the DSM6) is in the off position (out/disabled). This way, you avoid the additional load from running the signal through the internal resistors on the Speaker Selector and power loss. It's just like going through the SPW8 but you have the on/off switches of the selector box. The ISS6 now features the more effective removable input/output connectors. I hope that answers your question.

If you are going to buy a speaker switcher and leave all switches on. For less money would the SPW-8 do the same job?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Richard,
All speaker selectors and the SPW-8 help organize your wiring. The difference is in the features. There is no protection available or impedance matching in the SPW-8, which is why you need to use impedance-matching volume controls to make sure that the amplifier sees a load it can handle. We recommend using impedance-matching volume controls for our ISS and DSM speaker selectors to handle the protection. In fact, when the impedance-matching volume controls are used with the speaker selector, we recommend disabling the internal protection of the respective speaker selector.

This response confuses me and I'd love some clarification. You respond to the original question (whether to use a selector or the SPW-8) by saying that "The difference is in the features. There is no protection available or impedance matching in the SPW-8, which is why you need to use impedance-matching volume controls."
But you then go on to say that you recommend using the selector, but disabling the internal protection and letting impedance matching volume controls (which are required when using the SPW-8) handle the protection.
So I'm completely confused - if the difference b/t the selector and the SPW-8 are the protection features built into the selector, and your recommendation is to get the selector but then disable the protection features, why isn't the recommendation simply to use the (less expensive) SPW-8 in the first place?
Please note: I'm truly looking for clarification, not trying to start a debate.
Thanks.

I have a two channel signal coming from my amplifier to a SVC205 impedance matching volume control. Can I run multiple sets of speakers with one SVC205 using this panel behind it?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Doug,
It would depend on how many speakers you plan on running from the SPW-8. The SVC205 would only be able to handle 2-3 pairs of speakers. How many speakers do you plan on running from the SPW-8? Also, what kind of amp are you planning on using to power all of these?
