Figure 1: Front view of the Pro Intercom TR1 IFB Circuit Talent Receiver. This image displays the compact design, featuring two input jacks (1/4" and 3.5mm) and a rotary volume control knob on the front panel.
Front Panel
- 1/4" Input Jack: For connecting standard audio headphones or earpieces.
- 3.5mm Input Jack: For connecting smaller audio headphones or earpieces.
- Rotary Volume Control: Adjusts the audio output level to the connected headphones. This control can be turned down but not completely off. Internal jumpers allow for setting a minimum preferred level.
Rear Panel
- Green LED (Power Indicator): Illuminates when the unit is properly connected to the IFB system and receiving the required 18-30 VDC power.
- Red LED (Audio Traffic Indicator): Flashes to indicate that audio signals are being received by the unit.
- Single/Two Channel Switch: A recessed switch allowing the technician to select between single-channel and two-channel operation modes.
5. Setup
Follow these steps to set up your TR1 receiver:
- Connect to IFB System: Connect the TR1 receiver to your IFB circuit using the appropriate XLR cable (not included). Ensure a secure connection. The unit requires 18-30 VDC from the system's power supply.
- Verify Power: Once connected, the Green LED on the rear panel should illuminate, indicating that the unit is receiving power.
- Connect Headphones: Plug your headphones or earpiece into either the 1/4" or 3.5mm input jack on the front panel.
- Select Channel Mode: Use a small tool (e.g., a pen tip) to adjust the recessed Single/Two Channel switch on the rear panel to your desired operating mode. Consult your IFB system's documentation for the appropriate setting.
- Initial Volume Adjustment: Turn the rotary volume control knob on the front panel to its lowest audible setting before placing headphones on.
6. Operating Instructions
Operating the TR1 receiver is straightforward:
- Monitor Audio: With headphones connected and the unit powered, you should begin to hear audio from the IFB circuit.
- Adjust Volume: Slowly turn the rotary volume control clockwise to increase the audio level to a comfortable listening volume. Avoid excessively high volumes to prevent hearing damage.
- Observe Audio Traffic: The Red LED on the rear panel will flash when audio signals are actively being received, providing a visual confirmation of signal presence.
- Channel Selection: If you need to change between single and two-channel operation during use, carefully adjust the recessed switch on the rear panel. This typically requires a technician's intervention.
Note: The volume control cannot be turned completely off. Internal jumpers allow a technician to set the lowest preferred level, ensuring that some audio is always present for critical monitoring.
