It also expects an input of ~3.0 millivolts @1KHz. If your stereo amplifier does not have an input for a record player, you should use a phono preamplifier circuit between your turntable and your amplifier. The output of your turntable follows a gain-bandwidth curve called the RIAA compensation curve. The standard AUX input on your stereo does not.
