Default Active filter - Loudness

Hi guys!
I need a circuit of active stereo filter with a NE5532 or the MOSFET transistor 2SK170BL, where the fixed gain will be the fifth 50Hz .. with 5....10dB gain at 16kHz is 10....12dB gain and 1 ... 2kHz around gain 0dB.
With the input resistance of 22 ... 47Kohm and with output resistance <1kohm.
A big thank you for your cooperation!
