P.I.P.–BP1X & P.I.P.–BP1C
4 Specifications
Signal to Noise Ratio: Greater than
85 dB (equivalent input noise) from 20
Hz to 20 kHz.
Common Mode Rejection: Greater
than 90 dB at 60 Hz; greater than 60
dB at 20 kHz.
Crosstalk: Greater than 46 dB below
the signal level at 20 kHz.
Harmonic Distortion: Less than
0.05% THD at 1 kHz with any setting
and no compression. Less than 0.5%
at 1 kHz with 6 dB of compression.
Input Impedance: Nominally 36 k
ohms balanced and 18 k ohms unbal-
anced.
Maximum Input Level: +18 dB at
mid-band. Other bands will vary with
equalizer amplitude boost.
Nominal Gain: Unity ±0.5 dB.
Low-Pass Filter: Butterworth, 24-dB/
octave (4th order) with Sallen-Key to-
pology. Corner Frequency: Variable
from 80 Hz to 20 kHz via DIP switches.
Factory set to 20 kHz.
High-Pass Filter: Butterworth, 24-dB/
octave (4th order) with Sallen-Key to-
pology. Corner Frequency: Variable
from 23 Hz to 12 kHz via DIP switches.
Factory set to 23 Hz.
Reference Manual
Compressor: Driven by the audio and
the IOC
®
error signal. Threshold: con-
tinuously adjustable from 0 volts to 85
VRMS or "off" such that compressor is
driven by amplifier clipping. Dynamic
Range: greater than16 dB. Attack: 10
msec. Decay: 360 msec. Compres-
sion Ratio: :1.
Connectors
Input: Balanced female 3-pin XLR
on P.I.P.-BP1X .Removable barrier
block disconnect with mating con-
nectors on P.I.P.-BP1C .
Output: Balanced male 3-pin XLR
on P.I.P.-BP1X .Removable barrier
block disconnect with mating con-
nectors on P.I.P.-BP1C .
Maximum Output Level: +18 dB (into
a 600-ohm load).
Power Requirements: The P.I.P.-BP1
requires the ±24 volts that is typically
supplied by amplifiers with PIP capa-
bility.
