Even with not ideal input characteristics, measured characteristics are much less than declared. RMAA test results, using Audigy2 card input: Frequency response (from 40 Hz to 15 kHz), dB: +4.25, -9.05 Noise level, dB (A):-75.2 Dynamic range, dB (A) :77.2 THD, % :0.061 THD + Noise, dB (A) :-60.7 IMD + Noise, % :0.324 Stereo crosstalk, dB:-60.5 IMD at 10 kHz, % :0.151
All tests are at 24bit 96KHz. First test was with IR channel, at half of the volume, retest with 100% volume control and usb input connected gave a slightly better result: Frequency response (from 40 Hz to 15 kHz), dB:+4.14, -9.15 Noise level, dB (A):-88.0; Dynamic range, dB (A):86.9; THD, %:0.048; THD + Noise, dB (A):-62.9; IMD + Noise, %:0.212; Stereo crosstalk, dB:-76.1; IMD at 10 kHz, %:0.108; Here is the USB mode test result, 100% volume. In this mode, Line-out signal level was less than 0,5V, i needed to gain about 10dB. Frequency response (from 40 Hz to 15 kHz), dB:+4.20, -9.16; Noise level, dB (A):-80.6; Dynamic range, dB (A):81.4; THD, %:0.039; THD + Noise, dB (A):-63.9; IMD + Noise, %:0.191; Stereo crosstalk, dB: -65.1; IMD at 10 kHz, %:0.088.
