Physical Placement
The RPG8 speaker offers multiple placement options:

Power Connection
Connect the included power cable to the speaker's power input and then to a wall outlet. Ensure the voltage selector switch (115V/230V) is set correctly for your region before powering on the unit. For the US, use 115V.

Input Connections
The RPG8 offers various input options:
- Microphone Input: Use an XLR or 1/4" cable to connect a microphone to the 'MIC IN BAL' input.
- Line Input: Use RCA or XLR cables to connect line-level audio sources (e.g., mixer, media player) to the 'LINE IN' inputs.

Output Connections (Linking Speakers)
To link multiple speakers, use the 'LINE OUT BAL' XLR or 1/4" output. Connect this output from the first speaker to a 'LINE IN' input on the next speaker. This allows you to expand your sound system.

Operating
Volume and Gain Controls
Before connecting any audio source, ensure all volume and gain knobs are set to their minimum position to prevent sudden loud noises. Adjust the 'VOL' knob for microphone input, 'GAIN' for line input, and 'MASTER' for overall output volume to your desired levels.
2-Band EQ (Treble/Bass)
The built-in 2-band equalizer allows you to adjust the tonal characteristics of your audio. Use the 'TREBLE' knob to boost or cut high frequencies and the 'BASS' knob to adjust low frequencies. Remember that these adjustments affect all audio passing through the speaker.
Limiter and Power Indicators
The rear panel features 'LIMIT' and 'POWER' LED indicators. The green 'POWER' LED illuminates when the speaker is turned on. The red 'LIMIT' LED indicates that the speaker is reaching its peak volume or experiencing distortion. If the 'LIMIT' LED illuminates frequently, reduce the volume, gain, or master volume to prevent damage and maintain sound quality.
Voltage Selector
The voltage selector switch allows you to choose between 115V and 230V operation. This is crucial for matching the speaker to the local power supply. Always ensure this is set correctly before connecting power.
Maintenance
To ensure the longevity and optimal performance of your Rockville RPG8 speaker, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the exterior of the speaker. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish.
- Ventilation: Ensure that the amplifier's heat sinks (the red fins on the rear panel) are not obstructed. Proper ventilation is crucial to prevent overheating.
- Storage: When not in use, store the speaker in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Always use the ergonomically shaped handle for carrying. Avoid dropping the speaker or subjecting it to harsh impacts.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable not connected or faulty. | Ensure power cable is securely connected to speaker and outlet. Check outlet for power. |
| No sound output | Volume/gain knobs too low; input source not connected or faulty; faulty cable. | Increase volume/gain. Check input source and cables. Test with a different source/cable. |
| Distorted sound / LIMIT LED on | Input signal too high; volume/gain too high. | Reduce input signal level, volume, or gain until LIMIT LED is off or flashes minimally. |
| Humming or buzzing noise | Ground loop; faulty cables; interference. | Use balanced cables (XLR, TRS). Ensure all equipment is properly grounded. Try different power outlets. |
