Hi all!

I'm a owner of a Pioneer VSX-609RDS receiver and on the front speaker
system A
I have a pair of Pioneer S-H510V speakers (8 ohm, 90 dB/W).

Now I want to connect one more pair of speakers. These will then be
connected to
fron speaker system B. My purpose is to have both system A and B activated
at the
same time i.e. I want to hear sound from both A and B at the same time.

If I had understood everything correctly, the speaker pair A and speaker
pair B shall
have the same rating on BOTH impedance and sensivity in order for them to
sound
equally "loud".
But my big question is what ohm ratings the speakers must have in order to
avoid
overload the amplifier. Unfortunately the manual isnt good help : "Please
use
speakers rated between 8 ohm - 16 ohm".

What does that means? If only using system A it is obvious, the speakers
must be rated
between 8 and 16 ohm. But if I add another speaker pair on the system B? I
mean,
shall I see the speaker system A and B in serial or in parallel?!?! I think
I have seen
in some NAD manual that A and B seems to be in parallel.

Example 1:
Assume both A and B speakers are rated as 8 ohm. If A and B is in serial,
the total
will be 8+8=16 and it is within the range.

Example 2:
Assume both A and B speakers are rated as 8 ohm. If A and B is in parallel,
the total
will be 1 / (1/8+1/8) = 4 ohm and we are out of range!

So what should my ohm ratings be!?!?

Please help me!

If you add a second set of speakers and they are 8 ohms, and connected in
parallel, the impedance will be 4 ohms to the amplifier. This is going to
make the output stage run very hot, if the amplifier is not rated for 4
ohms. We see many amplifiers damaged from users adding on extra speakers
like this.

You can put them in series, but you will loose a lot of efficiency, and also
loose a lot of the damping factor.

What you really need is an amplifier that is rated to take a 4 ohm speaker
load for its operation. This will do the job for you.

If the manual says use speakers that are at least 8 Ohms and doesn't
say anything about not using both the A and the B set at the same time
then you should be alright if all 4 speakers are at least 8 Ohms.
There should be a section of the manual with the specifications for
the receiver--it'll have a section with something about the
sensitivity of the FM tuner part and input impedences or levels (in
Volts or miilivolts or microvolts) and stuff like that--and among all
of this should be a section that says that the output of the power amp
part has so many Watts of power per channel and such and it should
list the output or load impedence of the amp per channel. If that
figure is 4 Ohms or lower then you can hook up two 8 Ohm apeakers per
channel with no worries.
It's almost as sure as the sun rising in the east and setting in the
west that setting the receiver to run both the A and the B set of
speakers puts the A speaker and the B speaker for each channel in
parallel, not series.

I don't know about his receiver, but many receivers now switch B the
speakers into series with the A speakers. With no B speakers connected,
switching the A and B speakers on together will cause no sound as the series
circuit is open. Less commonly found is a 8-4 ohm switch on the back. I
believe this switch selects a lower voltage tap for 4 ohm speaker use on the
transformer that supplies the power to the output stage to reduce power for
less heat and stress.

The usual receiver owner's manual convention is to give the minimum
impedance for each speaker. If both speakers are in the 8-16 Ohm range,
most receivers will be OK. The manufacturers don't expect customers to
be able to do calculations.

Unfortunately, speaker impedance varies with frequency and some
speakers will may dip below 8 Ohms at some frequencies. Some receivers
are OK with this situation, some are not. It also depends how loud you
listen. If you tend to push the receiver to it's limit, trouble is more
likely (with or without the second pair of speakers). If you listen
quietly, problems are rare.

When both sets of speakers are running, the receiver will run warmer.
Make sure it has plenty of ventilation.

"Equally loud" will happen only if both sets of speakers are identical,
playing in identical rooms.

i have a sony digital reicever, i have hooked up 6 speakers to it
(there are only 5 speaker inputs, i bridged the two together). why is
it when i hook my minidisc player to the reicever, the sound or should
i say the base from the speakers sounds really hollow, i cant get good
base from my speakers, is this because of the two i bridged

Hi!

Really appreciate all answers I got already.
Tried on my receiver what happens if I switch on both A and B system,
with only speakers connected to A. And it still came sound from A speakers.
So it's seems more and more likely the A and B system are connected in
some kind of serial mode.

Hi!
Really appreciate all answers I got already!
Following your suggestion, I have copied exactly the text as it appears
in the manual, see at bottom.
But I'm still a bit confused, what does 80+80 means!?!
Is this the common way of telling that left channel can handle up to
80 W (at 8 ohm) and right channel can also handle 80 W (at 8 ohm)
or am I totally lost? Is anyone able to translate this into what the
rules are for what ohm rating I should follow? (I get all the other
technical stuff, but this one seems very hard to get, I dont know
why they managed to complicate this piece this much....)

By the way, there is an interesting note which might give a clue
in the chapter "Connecting You Equipment" under the section
called "Speakers".

"The receiver has two speaker systems, A & B. A is the main system
supporting the full complement of surround sound speakers. If you
switch on both A & B speaker systems, only the front speakers and
the sub woofer will be audible. No sound will come from the center
or surround speakers but multi channel sources will be down-mixed
to the active speakers so no sound will be lost. Similarly, if you choose
just the B system you'll only hear the speakers connected to the B system,
and multi channel sources will be down-mixed to these two speakers.
Please use speakers rated between 8 ohm and 16 ohm".

Hi,

Try it with just one (or should I say 5) instead of 2.

IF it sounds ok then that's the problem.

It sounds like you have connected the extra speaker or possibly others out
of phase, double check that the connections to the speakers are all the
same.
