Overall Performance
Nominal Limits Conditions
Gain: 0 dB +1 dB at 1 kHz; input gain set to nominal 0 dB
Dynamic range: 100 dB >/= 96 dB measured with ADC/DAC full scale mapped to
+17 dBV; this is THD +N measured at FS-60,
through A-weighting filter, and expressed in dB
below full scale
THD+N: .05% .1% at +10 Vrms output, for signal frequencies from
30 Hz to 20 kHz
Crosstalk at 1 kHz: -80 dB </= -70 dB terminate unused input terminals with 100 Ohm
balanced-connected resistors.
Crosstalk at 10 kHz: -60 dB </= -50 dB terminate unused input terminals with 100 Ohm
balanced-connected resistors.
Frequency response: 30 - 20 kHz +3 dB reference 1 kHz, measured at 0 dBV input
Output noise: -70 dBV </= -65 dBV channel noise measured through an A
weighting filter. Gain structure set to deliver
rated power and expressed in dBV
