THD+N (Total Harmonic Distortion + Noise)
Meas. Bandwidth 10 Hz to 20 kHz
Resolution 3 digits (dB-scale) or 4 digits (%-scale)
Residual THD+N balanced < -85 dB @ -10 dBu to +20 dBu
unbalanced < -74 dB @ 0 dBu to +14 dBu
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 (with Minirator test signal)
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.
