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?)
yes it's unbalanced
I forgot to mention it doesn't need any 'magic cables' either ( or
Shakti Stones ) to work

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.
