Quite good, but not suitable for all turntables

Have the system purchased from dealer, unfortunately much more expensive in this. Our misfortune to quickly decided.
But now the most important:
Built-in CD + DVD player is good, but DVD volume on TV via Scart very quiet, but normal volume on the speakers that run along automatically. If you like it so is satisfied.
No USB connection should actually be for the money these days there.
Turntable (Denon DP 29 F) does not run directly through "Aux" input, despite built-in "Aux" amplifier module. By going through by grinding to a separate DVD recorder it goes but, strangely, with ease on Aux input. An extra phono input is not on the device.
Sonically, the system is very good, even with additional, -35 years old (!!) "Heco" 3 way speakers as additional boxes is the system of performance, perfectly clear. Crystal-clear sound on now all 5 boxes.
Subwoofer also good, but should have switched over current system because it must always be switched off separately to save power. Go otherwise only in unnecessary standby. Not good if it is to be placed hidden.
Remote also good, Works from more unusual angular positions from the side to the device.

Since the unusual DVD player worked fine (image + sound) can be enthusiastic about the device when you leave a record player has not, or can connect via detours. Lt. Radio technicians there are such incompatibilities of Phono Aux connection probably unfortunately often with new equipment, because it is probably a technical problem of the sound frequencies and not the Anschlüssse itself! An external preamplifier brought no change.
