Instruments with VU (volume unit) and PPM (peak program meter) characteristics, with or without gain reduction meter (GRM) are available. Instead of bar-graph indication, also dot indication is optionally available. The instruments listed below are equipped with the PCBs 1.913.294 (VU or PPM) or 1.913.293 (VU or PPM with gain reduction meter) according to the table above. Please consult the circuit diagram relating to the corresponding assembly number. 1.913.102 * 1.913.104 1.913.106 * 1.913.108 1.913.322 * 1.913.324 1.913.606 * VU Meters: 20 20 20 20 20 20 10 dB GRM 10 dB GRM 10 dB GRM 10 dB GRM 10 dB GRM 10 dB GRM 3 + 2 1 100 80 60 40 20 0 1 2 3 5 7 10 100 80 60 40 20 170 100 80 60 40 20 3 + 2 1 0 1 2 3 5 7 10 20 100 80 60 40 3 + 2 1 0 1 2 3 5 7 10 20 20 100 80 60 40 100 80 60 40 3 + 2 1 0 1 2 3 5 7 10 20 100 80 60 40 3 + 2 1 0 1 2 3 5 7 10 20 100 80 60 40 3 + 2 1 0 1 2 3 5 7 10 20 100 80 60 40 3 + 2 1 0 1 2 3 5 7 10 20 dB % 20 dB % 190 VU % 20 dB % 20 dB % % 20 dB % 20 dB % 20 dB % VU VU VU VU VU VU 40 40 120 40 1.913.605 * 1.913.610 * PPM Meters: 1.913
