Speaker Impeadance & Video Connection

[Aburtch]

Setting up a first-time system [Yamaha RX-V659] and have two quick questions.

1. What is the speaker impedance of my 1988 Cerwin-Vega AT-8's? I can't find the info online. Or better yet, what do I set the impedance to on the receiver, 4 ohm or 8 ohm?

2. Is is better to connect the DVR/cable box to the receiver via S-video (highest quality output available on the box) and then to the TV via component video; OR is it better to just leave the coax video cable directly connected from the cable box to the TV and just run the audio through the receiver.

Thanks in advance.

Ummmm.... did I do something wrong? Maybe I should post these as individual questions in the speakers section and connecting a TV section...

You didn't do anything wrong. At times it takes time for a response

Set your receiver to 8 ohms, period.

If you will watch TV without the receiver at times, news and what not, you should send the rf video to the TV direct, then you don't need the receiver on. You can also send the s-video to the receiver and digital audio as well, then when you want to use the receiver's audio processing, you can, along with DVDs.
You can certainly test the receiver's ability to convert the s-video to component as then you only need component for TV and DVD use.

Great! Thanks very much.

Cerwin-Vega customer service actually responded to me and said the AT-8's were 6 ohms. But it sounds like you are saying I should set it at 8 ohms anyway? Sounds good and I can do it, but what's the reasoning behind it?

Also having tested the TV connection both ways, it looks the same. So I'm running S-video and digital audio out of the cable box to the receiver with a component video out of the receiver to the TV. This way I can watch sports and DVDs through the receiver but I've left the direct connection as well in order to be able to bypass the receiver if necessary.

Thanks very much for your response.

Receiver impedance setting

The 8/4 ohm impedance setting limits the power that can be delivered to low impedance speakers. It is there for the UL certification. Your receiver will perform better in the "8-ohm mode".

Make sure your receiver is well ventelated. If you are playing the speakers at high levels and hear clipping or distortion, turn the receiver volume down, you are exceeding the capabilites of the amp or the speakers.
