question

If I get the correct cables could I send the signal from a crosley turntable to this, then to a receiver? The ol' yamaha is running down at -18db to be able to hear the records at a decent volume from the passive speakers it's driving... I need it amped up a bit before it gets there methinks.
Asked by: Oliver
I can't answer from knowledge of the specific turntable, but every phono I've ever known for the past 40 years requires a phono preamp for two reasons. 1) The signal level is way, way too low for directly connecting to a headphone amp or any line-level device. 2) Most importantly phonographs are all recorded with a very treble-skewed EQ according to the standard RIAI curve, a phono preamp is designed to nullify that curve by being exactly opposite towards a heavy bass response. In short, there is no substitute for a phono preamp. Make sure it is labeled and defined as phono preamp.
