There's no reason why it shouldn't work.

the salesman toldme that I need a passive mixer to connect the cd player to
the amp to achieve the full power of the amplifer.otherwise the imput signal
would be too low... is he mad?

Definitely mad. The amplifier spec sheet says the input sensitivity is
0.775V RMS, and that usually means the minimum input level for full
power.

If he had said an active mixer and told you that the inputs to the
amplifier were balanced and the outputs of your CD player are
unbalanced (are they?) I'd say he was a little off, thinking that you
might need some more level in to get full power out. But a passive
mixer has no gain, so there's no reason to use on unless you want to
mix another source with your CD.

Yes of course it is. Do you think ppl design stuff not to be compatible these days ?

Yes he is. Like most 'hi-fi' ppl he has no real grasp of reality.

In fact your CD player has an output that is very slightly higher than the amplifier
requires ( exactly the *reverse* of what Mr Idiot Hi-Fi Shop said ). You simply avoid
using the amplifier at maximum to avoid distortion.

Btw - audio gear *does not* need 'matched impedances' to work well. Just another foolish
myth from the past that idiot clown audiophools repeat. Ideally, outputs should be
low(ish) impedance and inputs should be medium to high impedance. Which is exactly what
this gear does. In short, your choice is fine and it doesn't require any 'holy water' to
make it work optimally.

Yes. The input sensitivity is quite clearly stated in the linked page to
be 0.775V. If the CD player can put out 2V that's more than enough - no
problem as you can turn the level down.

But there's another inconvenience: the amp has separate L and R
controls. Unless your CD player also have a volume control you'll have
to adjust the L and R controls on the amplifier in parallel to adjust
your listening level. Not a problem if you don't mind that...

I forgot to mention it doesn't need any 'magic cables' either ( or Shakti Stones ) to work
just fine as intended, so don't buy any overpriced lunatic cables ( Monster etc ) that Mr
Hi-Fi Shop offers either.

I bought a cheap £24.99 DVD player from Comet a while ago, and the
salesman insisted that I really needed a special Monster brand scart
cable to get the best out of the player. The price of the scart
cable?... £89.99!

yes it's unbalanced

I already built a semi balanced cable RCA-XLR, with one end of the shield
disconnected. I used what I had at home, just a good microphone cable with 2
conductor and the shield... I think it will be very good

But there's another inconvenience: the amp has separate L and R
controls.
I don't have the volume control on the cd but there's no problem
and also no tone (bass/treble) controls that most people like to
have
I never use it. I like the sound the way it is.

I need this amplifier because I want to make loud party, so you know you
have to go to pro amps. Because I found that also expensive amplifier with a
lot of watts after the half way they sound distorted and without control.
