Page 26: Connection Of Your Plp
Connection of your PLP Once if the points mentioned above are respected, the connections between the PL-P and the amplifier as well as those connected to the line inputs of the PL-P should cause no problems. Only the connection to the turntable must be done with great care. The feeble signal levels coming from the cartridge of the tone-arm can easily be disturbed if the installation is not correct. - Page 27 (A1, B1 and C1). A1. Single-block turntable If hum still exists, then verify that the two main power cords (of the PL-P and the turntable) are connected to the mains supply, as close as possible to each other as suggested above in the connection explanation.
- Page 28 “X” is obligatory. For those who have a high-output MM cartridge fitted to the tone-arm, you can bypass the input transformers if desired (see jumpers section). If this is the case you lose the facilities of Tone-arm PL-P floating solutions mentioned above.
