Then plug this into the white Phono audio input in your stereo (this may allow monophonic audio into both sides of the amp, or it will just show up on the left side). If you don't have a Phono input (which has a built-in preamplifier for the extremely low Phonograph audio signals) and it's not loud enough to hear, you'll have to run it into an outboard Phono preamp first. If you get an audible 60-cycle hum with the phonograph hooked to your amplifier, youhave to run a grounding wire (just a bare or insulated copper wire) to connect the chassis of both pieces of equipment.

A simple RCA phono plug on a short wire spliced to the wires from the phono arm would probably work. Assume the red is positive and the black is negative. The fact there are only two wires suggest the cartridge is mono only (although you could substitute a stereo cartridge in the arm (you would need to be sure the weight rating of the cartridge is compatible with the arm). Note that the output from the cartridge in the phono arm is VERY low, so you MUST use a preamp equalized for phono (RIAA curve equalization) between the cartridge and the normal audio amplifier..
