Hello Fellow Members,

I have a question, can I use both speaker A and B at the same time? What are the disadvatage and advantages?

1.Yes, you can.

2.Stress on the receiver.

3.You can play two pairs of speakers at the same time.

You'd be much better off playing A or B, but not together.

When you play A and B together, the receiver see a parallel load on its end. For example, if you have an 8 ohm load on terminal A and an 8 ohm load on B and you play them at the same time...the receiver needs to drive a 4 ohm load. Therefore, if you have two 4 ohm loads connected to terminals A and B respectively...then the receiver is driving a 2 ohm load. Most receivers that have A and B terminals do not recommend driving two 4 ohm loads at the same time becasue most receivers cannot drive a 2 ohm load.

So be very careful not to ask too much from your receiver...you could bring it to its knees.

Speaker A and B............Yamaha's reasons for offering it today.

You can drive your home theater speakers off of the A channel and your stereo 2 channel speakers off the B channel.
So when your using the Home theater side,B is off.When listening to music in 2 channel A is off as well as the Effect........
If anyone's into Yamaha.

Make sure to ventilate well and check your receiver to see how hot it is. Most higher quality receivers/amps can handle this load depending on the speakers connected and power (volume) applied. If you have a sub, set the x-over as high as possible.
