CDP output enough for line-level active crossover?

Klimon · 14th April 2011, 10:03 AM

Hi chaps,

I'm running a tda1541 cdp with modified output stage (bypassed last opamp = better sound but less output) > diy integrated tube amp. I would like to add active powered subs and the idea of adding a high-pass filter in front of the tube amp appeals to me (the amp is lowish on power for my current speakers)...

Hence: would you think that the CDP has sufficient output voltage to connect it directly to a cheap active crossover (used Behringer CX2310 is in my price-league) that passes on the 'low' signal to the sub amps and the 'high' signal to the integrated tube amp?

Thanks for any advice!!

Simon

CDP is generally 2Vac to 2.2Vac @ maximum output.
That is roughly 3Vpk.
What will 3Vpk do to your crossover and to the stages that follow it?
