Setup
Proper setup ensures optimal performance and safety of your TS310 speaker.
1. Physical Placement
The TS310 offers multiple placement options:
- Pole-Mounting: Use a standard speaker pole stand. Ensure the stand is stable and rated for the speaker's weight.
- Wedge Monitor: Position the speaker on its side for use as a floor monitor.
- Bracket Installation: Utilize M6 suspension points for fixed installations with appropriate brackets (sold separately).
- Flown Application: For suspended installations, consult a qualified professional to ensure safe rigging.

2. Connections
Refer to the rear panel diagram for connection points:
Figure 4: Rear panel controls and connections of the TS310.
- Power Connection: Connect the supplied power cable to the AC input on the rear panel and then to a grounded power outlet.
- Audio Inputs (Input 1 & Input 2): Use XLR or 1/4-inch TRS cables to connect your audio sources (e.g., mixer, microphone, instrument) to the dual combo inputs.
- XLR Link Output: Use an XLR cable to connect this output to the input of another powered speaker (e.g., another TS310) to expand your PA system.
Operating
Follow these steps for basic operation of your TS310 speaker:
- Power On: Ensure all connections are secure. Turn on your audio sources first, then turn on the TS310 using the Power switch on the rear panel.
- Volume Control: Adjust the independent Level controls for Input 1 and Input 2 to set the desired volume for each source. Start with lower volumes and gradually increase.
- Contour EQ Switch: Engage this switch to apply a pre-set EQ curve that enhances bass and treble, often suitable for music playback. Disengage for a flatter frequency response, typically preferred for live vocals or instruments requiring precise mixing.
- Ground-Lift Switch: If you experience hum or buzzing, try engaging the Ground-Lift switch. This can help eliminate ground loop noise.
- Power Off: Before disconnecting power, turn off the TS310 first, then turn off your audio sources.
Maintenance
Regular maintenance helps prolong the life of your TS310 speaker:
- Cleaning: Use a soft, dry cloth to clean the exterior of the speaker. Do not use solvents or abrasive cleaners.
- Grille: Periodically check the front grille for dust or debris and gently clean if necessary to maintain optimal sound dispersion.
- Storage: When not in use, store the speaker in a dry, temperate environment, protected from dust and extreme temperatures.
- Inspection: Regularly inspect power cables and audio cables for any signs of damage. Replace damaged cables immediately.
Troubleshooting
If you encounter issues with your TS310, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable disconnected; Power outlet not active; Power switch off. | Ensure power cable is securely connected. Check power outlet with another device. Verify power switch is in the 'ON' position. |
| No sound | Input level too low; Audio source not sending signal; Damaged audio cable; Mixer output level too low. | Increase Input Level controls. Check audio source. Test with a different audio cable. Ensure mixer/source output is active. |
| Distorted sound | Input level too high (clipping); Speaker volume too high; Damaged driver. | Reduce Input Level controls. Lower the overall volume. If distortion persists at low volumes, contact support. |
| Hum or buzzing noise | Ground loop; Interference from other electronics. | Engage the Ground-Lift switch. Try connecting the speaker to a different power circuit. Move speaker away from other electronic devices. |
