Setup
Proper setup ensures optimal performance and safety. Follow these steps for initial setup:
Power Connection
- Ensure the Level control on the rear panel is set to its minimum position.
- Connect the supplied AC power cable to the AC Power Input on the rear panel of the HD1221.
- Plug the other end of the power cable into a grounded electrical outlet.
Audio Connections
- Connect your audio source (e.g., mixer, instrument) to the Main Input (XLR) on the rear panel.
- If connecting multiple loudspeakers, use the Loop Out (XLR) to send the signal to the next loudspeaker.
Mounting Options
The HD1221 offers several mounting options for flexibility:
Pole Mounting
Figure 5: The HD1221 mounted on a pole, typically above a subwoofer like the HD1501 for a full-range PA system.
The HD1221 can be mounted on a standard speaker pole stand. Ensure the stand is stable and rated for the weight of the loudspeaker (approximately 58 lbs).
Stage Monitor Placement
Figure 6: The HD1221 configured as a stage monitor, utilizing its 60-degree angle for optimal sound projection towards the performer.
The cabinet design allows for use as a stage monitor with a 60-degree angle. Place the loudspeaker directly on the stage floor, angled towards the performer.
Flying/Suspension
Figure 7: The HD1221 suspended vertically using appropriate rigging hardware.
Figure 8: The HD1221 suspended horizontally using appropriate rigging hardware.
The HD1221 can be flown both vertically and horizontally. Always use certified rigging hardware and consult with a qualified professional for safe installation. The user-rotatable horn allows for precise sound placement in either orientation.
Operating Instructions
Once the loudspeaker is set up, follow these steps for operation:
- Power On: Turn on your audio source (mixer, etc.) first, then turn on the HD1221 loudspeaker. The 'Power Light On' indicator should illuminate.
- Set Voicing Mode: Use the Voicing Mode switch on the rear panel to select the appropriate setting for your application:
- Contour: Provides a sculpted frequency response, often suitable for music playback.
- Flat: Offers a neutral frequency response, ideal for critical listening or when external EQ is used.
- Monitor: Optimizes the frequency response for use as a stage monitor, reducing low-end rumble and enhancing clarity.
- Adjust Level: Slowly increase the Level control on the rear panel to achieve the desired volume. Monitor the 'Sig/Limit' indicator; if it flashes frequently or stays lit, reduce the input level from your source or the HD1221's level to prevent distortion and potential damage.
- Power Off: When finished, turn off the HD1221 loudspeaker first, then turn off your audio source.
