1. Introduction
Thank you for choosing the Speco Technologies SPC-30RT Weatherproof PA Speaker. This speaker is designed for public address applications requiring durable, weather-resistant audio output. Featuring a built-in 75/25V transformer, it is suitable for use in constant voltage audio systems. This manual provides essential information for the safe and effective installation, operation, and maintenance of your speaker.
2. Safety Instructions
- Read all instructions: Before installation and operation, carefully read and understand all instructions in this manual.
- Electrical Safety: Installation should be performed by qualified personnel. Ensure all power to the amplifier or PA system is disconnected before making any wiring connections. Incorrect wiring can cause damage to the speaker, amplifier, or pose an electrical hazard.
- Mounting: Use appropriate hardware and ensure the mounting surface can safely support the speaker's weight. Improper mounting can lead to the speaker falling, causing injury or damage.
- Placement: While weatherproof, avoid direct exposure to extreme weather conditions (e.g., prolonged heavy rain, direct sunlight in extreme heat) to maximize product lifespan.
- Cleaning: Disconnect power before cleaning. Use a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Servicing: Do not attempt to service this product yourself. Refer all servicing to qualified service personnel.

4. Setup and Installation
Follow these steps for proper installation of your PA speaker.
4.1 Mounting the Speaker
- Select Location: Choose a suitable mounting location that provides optimal sound coverage and can safely support the speaker's weight. Ensure the surface is stable and free from obstructions.
- Attach Bracket: If the mounting bracket is separate, attach it securely to the speaker using the provided hardware.
- Mark Drilling Points: Hold the speaker with the attached bracket against the mounting surface. Use a pencil to mark the drilling points for the bracket.
- Drill Pilot Holes: Drill pilot holes at the marked points. Ensure the drill bit size is appropriate for the mounting hardware.
- Secure Speaker: Fasten the speaker and bracket assembly to the mounting surface using the provided screws and washers. Ensure it is tightly secured to prevent movement or detachment.
- Adjust Angle: Loosen the adjustment screws on the bracket to tilt and swivel the speaker to the desired angle for optimal sound projection. Tighten the screws firmly once the desired position is achieved.

4.2 Wiring Connections (75/25V Transformer)
The SPC-30RT speaker is equipped with a 75/25V transformer for use in constant voltage public address systems. This allows multiple speakers to be connected to a single amplifier over long cable runs with minimal power loss.
- Power Off: Ensure the amplifier or PA system is completely powered off before making any connections.
- Identify Wiring: The speaker will have wires extending from its rear. These are typically color-coded for different wattage taps (e.g., 75V, 25V, common). Refer to the speaker's specific wiring diagram (usually found on a label on the speaker itself or in a separate diagram) to identify the correct wires for your desired power tap and voltage.
- Connect to Amplifier: Connect the speaker wires to the appropriate output terminals on your 75V or 25V constant voltage amplifier.
- Connect the common wire (often black) from the speaker to the "COM" or "GND" terminal on the amplifier.
- Connect the selected voltage tap wire (e.g., for 75V or 25V) from the speaker to the corresponding "75V" or "25V" output terminal on the amplifier.
- Secure Connections: Ensure all wire connections are secure and properly insulated to prevent short circuits.
Important: Do not connect this speaker directly to a standard low-impedance (e.g., 4-ohm, 8-ohm) amplifier output without using the transformer. Doing so will damage the speaker and/or amplifier.
5. Operating Instructions
Once the speaker is properly installed and wired to your PA system:
- Power On: Turn on your PA amplifier or system.
- Audio Source: Ensure your audio source (microphone, music player, etc.) is connected and active.
- Adjust Volume: Gradually increase the master volume on your amplifier to the desired listening level. Avoid setting the volume too high, which can cause distortion or damage to the speaker.
- Monitor Sound: Listen for clear audio output. If distortion occurs, reduce the volume.
6. Maintenance
- Cleaning: Periodically wipe the speaker's exterior with a soft, damp cloth to remove dust and dirt. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect the mounting bracket and hardware for any signs of loosening or corrosion. Tighten as necessary. Check wiring for any damage or fraying.
- Weather Protection: While weatherproof, ensure the speaker is not submerged in water or exposed to high-pressure water jets.
