11.3 Audio
Please note: The audio specifications
are referenced to 0.775 V (0 dBu).
Measurements were made at the out-
put of the IQ-PIP-USP2/CN module.
Digital Signal Processor (DSP): 60
MHz Motorola 56002 DSP processor
provides 30 million operations per
second.
Analog to Digital Conversion
(ADC):
24-bit, 48-kHz sample rate,
Delta-Sigma converter.
Digital to Analog Conversion
(DAC):
24-bit, 48-kHz sample rate,
Delta-Sigma converter.
Signal to Noise Ratio: Greater than
100 dB (A-weighted, 20 Hz to 20
kHz, audio sourced from muted
CobraNet™ channels).
Frequency Response: ±0.5 dB, 20
Hz to 20 kHz (referenced to 1 kHz, 0
dBu input signal).
Distortion: Less than 0.05%
THD+N, 20 Hz to 20 kHz (refer-
enced to 1 kHz, 0 dBu input signal).
Crosstalk: better than –80 dB, full-
scale input level, 20 Hz to 20 kHz
input frequency sweep, 20 Hz to 20
kHz bandwidth.
Listen Bus Distortion: Less than
0.1% THD+N, 20 Hz to 20 kHz band-
width (1 kHz, 0 dB full scale input
signal at the active PIP2 AO1 or AO2
input).
Listen Bus Signal to Noise: Greater
than 80 dB, 20 Hz to 20 kHz band-
width (audio sourced from muted
amplifier channels. Measured at re-
ceiving CobraNet node outputs).
Maximum Output Level: +20 dBu.
