The PZM-11LL has a line-level output. It requires:
Connect the PZM-11LL audio (+) lead to the cable hot conductor, and connect the cable hot conductor to the RCA plug's tip terminal.
Connect the PZM-11LL ground lead to the cable shield, and connect the cable shield to the RCA plug's ground terminal.
Don't connect to the audio (–) terminal on the PZM-11LL. If you wire the audio (–) terminal to the ground terminal in an attempt to unbalance the signal, the signal might be low level or distorted.
If the mic is picking up quiet conversation, use an XLR connector with a step-up transformer on the VCR end. See below.
The signal level of the PZM-11LL is 1.4 volts at 94 dB SPL. But at a quiet conversation level of 70 dB SPL, the signal level is 0.09 volt. This is 12 dB lower than the nominal input level of a VCR, which is about 0.35 volt.
