Control Panel Features:
- Channels 1 & 2 (MIC/Line Inputs): Each channel features XLR and 1/4" line inputs, allowing connection of microphones or line-level instruments. Each channel has independent High (treble) and Low (bass) EQ controls, and a Volume knob. Phantom power is available for XLR inputs.
- Channel 3 (AUX IN): An 1/8" (3.5mm) stereo jack summed to mono, ideal for connecting external audio devices like smartphones or MP3 players. This channel also has independent High (treble) and Low (bass) EQ controls, and a Volume knob.
- Master Volume: A global control for the overall output level of the PA system.
- POWERLINK™ (IN/OUT): XLR connections that allow two or more PW50 units to be linked together, functioning as a single, synchronized PA system.
- SUB OUT: An output for connecting an external subwoofer, which diverts low frequencies from the PW50's internal speakers to the subwoofer for enhanced bass response.
- POWER Switch and Indicator: Turns the unit on/off. A blue LED indicates power status.
5. Setup
- Placement: Position the PW50 on a stable, flat surface or mount it on a standard speaker stand using the 35mm socket. Ensure proper ventilation.
- Power Connection: Connect the supplied power cable to the AC input on the rear panel of the PW50 and then to a suitable power outlet. Do not power on the unit yet.
- Connect Inputs:
- For microphones, use an XLR cable and connect to Input 1 or 2.
- For instruments (e.g., guitar, keyboard), use a 1/4" TS cable and connect to Input 1 or 2.
- For external audio devices (e.g., smartphone, MP3 player), use an 1/8" (3.5mm) stereo cable and connect to the AUX IN on Channel 3.
- Initial Volume Settings: Before powering on, ensure all Channel Volume knobs and the Master Volume knob are set to their minimum (fully counter-clockwise) position.
- Power On: Flip the POWER switch to the 'ON' position. The blue power indicator LED will illuminate.
6. Operating Instructions
Once the PW50 is set up, follow these steps to begin operation:
- Adjust Channel Volume: Slowly increase the Volume knob for the channel you are using (Channel 1, 2, or 3) until you hear sound at a comfortable level.
- Adjust Master Volume: Use the Master Volume knob to control the overall output level of the entire system. This allows you to adjust the total loudness without affecting the individual channel mixes.
- Equalization (EQ): Use the High and Low EQ knobs on each channel to shape the tone of your input. Turn the High knob clockwise to increase treble, and counter-clockwise to decrease it. Do the same for the Low knob to adjust bass frequencies.
- Using POWERLINK™: To expand your sound system, connect the POWERLINK™ OUT of one PW50 unit to the POWERLINK™ IN of another PW50 unit using an XLR cable. This allows multiple units to function as a single, synchronized PA system.
- Connecting a Subwoofer: For enhanced bass, connect an active subwoofer to the SUB OUT port. This output sends a dedicated low-frequency signal to the subwoofer.
7. Maintenance
Proper care and maintenance will ensure the longevity and optimal performance of your Powerwerks PW50 PA System:
- Cleaning: Regularly wipe the exterior of the unit with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or waxes.
- Storage: When not in use for extended periods, store the unit in a cool, dry place, away from direct sunlight and extreme temperatures.
- Ventilation: Ensure that the ventilation grilles are free from dust and debris. Use a soft brush or vacuum cleaner to gently remove any buildup.
