Multi-Channel Setup

[photoeye]

Hi,

I have an older Pioneer Elite AV receiver that has multichannel inputs and outputs. My plan is to connect the Pioneer Blu Ray players Multi out
into the Elite receiver multi inputs for the Dolby and DTS HD Audio.

This Elite model can switch between 6ohm and 8ohms. I have switched
it to 6ohms. Would there be any issues driving a set of speakers that
are 4ohms with 86dB eff. ?

For most people's home theater setup, even if you have Full Tower speakers that can go low, let say 30-40hz. Do you select your Front Speakers to FULL or Small? with a subwoofer. or do you select FULL and cross over to the sub what your FULL towers cannot handle?

thx.

86 isn’t a very high SPL, and adding the 4 ohms is going to tax the receiver. Bass notes tend to cause the load to the amp drop even lower, so crossing over the speakers (no matter how low they go) will help offset things a bit.

my receiver has the microphone where it does the auto calibration for distance,delay,etc...

my question is when you are using the multi-channel input, are these calibration settings defeated or bypassed?

you would have to manually set those setting on the blu ray player
itself for correct distance, delay,speaker type,etc...?

if it's bypassed then in this type of setup, the where the blu ray player's
multi-out goes into the receiver's multi-in, the receive only acts as a volume
control or is there more to this?

thanks

actually the highest loads aren't mostly in the subs range.

They are from 50hz to 300hz.

However if you have a ported design it is generally advised to multiply the F3(bottom response by 2 to get your crossover) Otherwise you can damage your driver significantly. You can get by with an 80hz cross on a 50hz response, but don't push the speaker too hard.

The large small setting depends entirely on your preferences and setup.

But in your case small would be the preferred setting.

Just because a speaker has a response to 30hz doesn't mean you want to push it that low. 60-80hz are acceptable for most towers. But I suggest you stick to 80 unless you are using a behemoth of a sub and don't have good response above a certain frequency.
