Audio
Please note: The audio specifica-
tions are referenced to 0.775 V (0
dBu). Measurements were made at
the output of the IQ-PIP-USP2 mod-
ule, itself.
Digital Signal Processor (DSP):
60 MHz Motorola 56002 DSP
processor provides 30 million op-
erations 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.
Input Impedance: Nominally 20 k
ohms balanced and 10 k ohms un-
balanced.
Maximum Input Level: +20 dBu.
Dynamic Range: >100 dB (A-
weighted, 20 Hz to 20 kHz).
Frequency Response: ±0.5 dB from
20 Hz to 20 kHz.
Common Mode Rejection (CMR):
50 dB (typical).
Total Harmonic Distortion + Noise
(THD+N): <0.05% (1 kHz, 0dBu).
Daisy Output Impedance: Nomi-
nally 150 ohms (balanced).
Maximum Output Level: +20 dBu.
IQ System Data Acquisition
Eight Channel, 12-bit Analog to Digi-
tal Converter running at 100 kHz.
Input/Output Monitor Accuracy:
Typically ±1 dB.
7 IQ Address Tables
The following pages in this section
contain lookup tables for every valid
IQ address. The valid addresses
are 1 to 250. Remember that ad-
dress “0” (zero) will put the IQ-PIP-
USP2 into a stand-alone mode where
it is invisible to the IQ System and
acts like a “dumb” balanced audio
input. Do not use an address num-
ber higher than 250! Addresses
above 250 are reserved for special
system use. Remember: No two IQ components
of the same type which are con-
nected to the same Crown Bus loop
can have the same address.
To use the IQ address tables, simply
find the address you want and set
the IQ address switch of the IQ-PIP-
USP2 as shown. See Section 3.1
also.
