The transmitter failsafe input is located at J1–17. The failsafe input is used to mute and unmute the transmitter
RF output. This input is designed for the connection of a control device such as a remote control unit failsafe
connection. To permit immediate on–air operation, the unit is equipped with a pre–wired 25–Pin D–Type inter-
face connector. The connector is located in the accessory kit and contains a failsafe input jumper. To permit
immediate operation, install the connector on J1.
POWER SUPPLY FAULT INDICATOR –
The power supply fault is located at J1–23 and is active low. This fault occurs when the power supply registers a
fault condition. The power supply fault conditions are as follows. 1) 48V is out of regulation (+8V or –1V). 2)
+/–12V supply is out of regulation (+/–0.5Volts). 3) A surge current from the +48Volt supply occurs. 4) Heat-
sink temperture on the power supply exceeds 70C.
PAV SAMPLE –
A PAV (power amplifier voltage) sample is provided at J1–24. The sample will output 2 volts for a PA voltage
of 50 volts.
ANALOG RIGHT CHANNEL INPUT –
The analog right channel input + is located at J2–1. The analog right channel input – is located at J2–2. The
analog right channel input ground is located at J2–3. The input impedance can be configured for 600 Ohms or
10 k Ohms. The input level can be configured for –10 dBm, 0 dBm, +4 dBm, or +8 dBm.
ANALOG LEFT CHANNEL INPUT –
The analog left channel input + is located at J2–9. The analog left channel input – is located at J2–10. The ana-
log left channel input ground is located at J2–11. The input impedance can be configured for 600 Ohms or 10 k
Ohms. The input level can be configured for –10 dBm, 0 dBm, +4 dBm, or +8 dBm.
AES/EBU INPUT –
The AES/EBU input + is located at J2–8. The AES/EBU input – is located at J2–7. The AES/EBU signal is po-
larity independent. Therefore, the signal cables can be connected to J2–8 and J2–7 in any combination.
SCA AUDIO INPUT –
The SCA audio input + is located at J2–12. The SCA audio input – is located at J2–13. The SCA audio input
ground is located at J2–14. The input impedance can be configured for 600 Ohms or 10 k Ohms.
MODULATION MONITOR CONNECTION.
The PNP 1000 is equipped with an RF SAMPLE receptacle. The sample port is for the connection of a modulation
monitor or test equipment.
The receptacle will provide 3.1V RMS at 1000 watts.
Connect the desired equip-
ment to the RF SAMPLE receptacle as required.
ANTENNA CONNECTION.
A Type–N RF output receptacle is provided for the connection of the antenna to the transmitter. Connect the antenna
to the RF output receptacle.
