P.I.P.-RPA
Frequency Response: ±0.5 dB from
30 Hz to 15 kHz without isolation
transformers. ±0.5 dB from 50 Hz to
15 kHz with isolation transformers.
Harmonic Distortion (THD): Less
than 0.1% THD from 20 Hz to 20 kHz.
Less than 0.5% THD from 30 Hz to 15
kHz at +10 dB.
Common Mode Rejection: Better
than 50 dB from 20 Hz to 10 kHz.
Better than 45 dB from 10 to 20 kHz.
P.I.P.-RPA(T) better than 40 dB from
10 to 20 kHz.
Crosstalk: Line: Better than –60 dB
from 20 Hz to 20 kHz. Mic: Better
than –42 dB.
Controls: One input mode switch
and one input level control for each
main audio input (A–D) located on
front panel of the PIP. One 8-seg-
ment priority DIP switch located on
the component side of the top circuit
board. One voice-over sensitivity and
duck level control each for Input A
and C, located on the component
side of the top circuit board.
Connectors: Buchanan-type screw-
down barrier connectors.

Main Audio Inputs
Four independent AC-coupled bal-
anced audio inputs are provided,
A–D. They are switchable as mic,
line, or mic with phantom power
inputs. Each input channel also in-
cludes a remote-controlled attenua-
tor. A routing/priority switch assigns
an override priority to each input.
Inputs A and C each have sensing
circuitry which can be used to acti-
vate an attenuation (duck) circuit to
override other inputs.
Nominal Input Impedance: Line:
11.4 K ohms balanced. Mic: 1.4 K
ohm balanced.
Phantom Power: 18 VDC at 9 mA
with a 2 K ohm output impedance.
Recommended Source Imped-
ance: Mic or Line: 600 ohms or less,
balanced or unbalanced.
Maximum Input Level: Line: +36
dB. Mic: +16 dB.
Nominal Gain: Line: Adjustable from
0–36 dB with user-accessible gain
pots. Mic: Adjustable from 20–56 dB.
Remote Control Inputs
One remote input for the attenuator
of each main audio input (A–D). Two
wire format requiring a 10 K ohm
potentiometer across the 10 V output
and the remote input terminals. Nomi-
nal input impedance of 10 K ohms. A
10 VDC source is used to control the
attenuator (VCA). +10 V at the re-
mote input yields 0 dB attenuation
and +5 V or less yields a maximum
84 dB attenuation. A control voltage
of less than +5V is not recommended.
Tie Input
A logic input which “ties” the audio
and input priorities of the main audio
inputs (A–D) together. The audio rout-
ing and priority status is set by the
priority DIP switch on the top circuit
board. Input impedance is 430 K
ohms. Minimum voltage to force Tie
function on: 4.2 V. Maximum allow-
able voltage for Tie to be off: 2.4 V.
