Murraypro PPM6 4-Channel Program Meter
This used Murraypro PPM6 is in good physical condition with some signs of use. This unit is being sold for spares and repairs. No returns
The self-contained PPM-6 provides physical A1, A2, A3, A4 Peak Programme Metering, M&S level monitoring, overload indication, dual stereo phase verification and audio presence confirmation simultaneously , without cluttering the video display monitor in any way! PEAK PROGRAMME METERING PPM monitoring is provided on six illuminated miniature meters. True PPM scaling together with the classic fast attack and slow decay times are ensured by the full specification precision meter drive amplifiers. The miniature movements that are fitted in this 1 U height have a very slightly relaxed specification, boast a surprisingly large 42 x 20 mm scale and closely emulate the full-sized BS 6840 meters.
INPUT MONITORING PPM-6 is configured so the A1, A2, A3, A4 input signals are displayed on the respective left hand meters. “M & S” MONITORING Mix and S eparation meter monitoring, switch selected from either A1 & A2, or A3 & A4 input pairs, is available on the right hand panel meters. Optionally the displayed M signals may be increased in level by 3dB, in accordance with BBC preferences, by adjustment of two further internal links. PEAK LEVEL INDICATOR Four independent red LEDs indicate peak input signal levels in excess of +8.15dBU ( +0.15dB) for each channel.
These LEDs conform with the full PPM specification, and are not subject to the ballistic considerations of meter movements. PHASE VERIFICATION Correct A1:A2 & A3:A4 phasing is indicated by green illumination of the phase indicator. Incorrect phasing of either channel pair is immediately obvious as the respective PPM-6 phase indicator changes colour to red . The phase indication is extremely reliable, and is vital in an editing environment, where the highly visual GO ~~ NO -GO indicators provide this vital information instantly, preventing expensive mistakes which may only become apparent much later!
