Safety Instructions
- Ensure the loudspeaker is placed on a stable, level surface or securely mounted on a compatible stand using the integrated stand opening.
- Do not expose the loudspeaker to water, moisture, or extreme temperatures.
- Avoid blocking ventilation openings to prevent overheating.
- Do not attempt to open or service the loudspeaker yourself. Refer all servicing to qualified personnel.
- Use only specified cables and connectors.
Setup
Unpacking
Carefully remove the loudspeaker from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future transport or storage.
Placement
The Dibeisi Q1536 is designed for floor mounting or stand mounting. When using a stand, ensure it is rated for the loudspeaker's weight and is stable. Position the loudspeaker to optimize sound dispersion for your specific environment.
Connections
The loudspeaker features 6.3 mm jack and 2x banana connectors for audio input. Ensure all connections are secure before powering on your audio system.
- Connect your audio source (e.g., amplifier, mixer) to the loudspeaker's input terminals using appropriate cables.
- Ensure the amplifier's power is off before making any connections.
- Match the impedance of the loudspeaker (8 Ohm) with your amplifier's output impedance for optimal performance and safety.
Operating Instructions
Powering On
Once all connections are made, power on your audio source (e.g., amplifier) first, then gradually increase the volume to the desired level. Avoid sudden high volume inputs.
Volume Control
Adjust the volume from your audio source. Do not exceed the loudspeaker's maximum power handling capacity (700 W peak, 300 W RMS) to prevent damage.
Powering Off
Before powering off your audio source, reduce the volume to minimum. This prevents sudden pops or thumps that could damage the loudspeaker.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the loudspeaker. Do not use liquid cleaners or abrasive materials.
- Storage: If storing the loudspeaker for an extended period, keep it in a dry, cool place, ideally in its original packaging to protect it from dust and physical damage.
- Inspection: Periodically check cables and connectors for wear or damage. Replace any damaged components immediately.
