NEUTRIK test results came out as expected.
Although seen in preset 2dB common errors like these have already been corrected with Neutrik is normal.
The noise level was measured at -62 max volume level. Traffic should not be -65 H Its overall value creation. This corresponds to 102 dB dynamic range of 40dB to the overall amplifier gain factor.
The max level (30W output and tone controls defeat) distortion is measured as follows.
THD + N
30Hz 0.5%
250Hz 0.2%
500Hz 0.1%
1kHz 0.1%
5 kHz to 0.1%
10kHz 0.2%
20kHz 0.3%
The measured values for 1W output power of 465 NGOs are almost equivalent to that given in the general catalog. 0.08%
+ 3dB stop distortion measured for 10% overload. It complies with basic standards.
The frequency characteristics were measured only between 10Hz to 30kHz +/- 2dB skew.
