S2-MPPM Meterbridge PPM Meter Panel

The S2-MPPM panel has two fast-reading moving-coil meters with PPM-style scale.

The PPMs have a 1-7 scale and are configured such that a 1kHz signal, at 0dB at the PGM output, will indicate a meter reading of 4. Each mark on the PPM scale indicates a 4dB change in signal level.
