Excellent performance, but fails Grade A on test level and phase.
The latter demonstrates a common problem - a single shared D/A convertor resulting in a time-shift between channels. Though not a problem normally - it is equivalent to a path difference in air of only 10mm it causes 3dB loss at 10kHz when combined to mono - unacceptable in broadcast use |
