PROGRAM INPUT AND OUTPUT WIRING SCHEMES
(Refer to Figures 3.1 and 3.2)
The diagrams below illustrate the correct wiring of balanced
and unbalanced program inputs and outputs.
PROGRAM INPUT AND OUTPUT CONNECTIONS
(Refer to Figure 3.0)
The PIR-88M Infrared Modulator Matrix provides
connections for eight program channels.
The Program Input and Output connections are made
through a 48-pin screw terminal block mating connector.
PROGRAM INPUTS: (S) = Shield, (+) = High, (–) = Low,
electronically balanced input, accepts balanced or
unbalanced signals from line-level devices. Nominal
input level is +4 dBu with maximum input level of + 24
dBu.
PROGRAM OUTPUTS: (S) = Shield, (+) = High, (–) = Low.
The outputs are loop through from the inputs. Output
impedance and level is determined by the source device
feeding the PIR-88M.
BNC RF OUTPUTS
(Refer to Figure 3.3)
The PIR-88M Infrared Modulator Matrix provides
connections for eight infrared emitter panels. Channel one
output corresponds to channel 1 audio input. Depending
on the programming set-up - when a Preset is selected -
the BNC jacks will be routed to the appropriate RF
modulator.
