| vu + PPM |
vu-Indicator and Peak Program Meter
According to IEC 60268 and DIN 45406, PPM Type I, IIa and Nordic.
Both meters with adjustable reference and with analog & numerical peak-hold readout. |
| Polarity Test |
Positive / Negative detection through internal microphone or XLR/RCA connector. Checks polarity of tweeters, midrange-speakers, woofers, sub-woofers and cables. Down to 10 dB S/N ratio of input signal. MR2 or MR-PRO provides the test signal. |
| Balance Error |
Indication range 0.0 % to 100 %
Deviation from perfect balance in % or *1 |
| Sweep |
Frequency Sweep: Level as function of frequency.
Time Sweep: Measurement of level, THD+N and frequency as function of time. |
