- Power Connection: Connect the supplied power cable to the AC IN socket (1) and then to a suitable grounded power outlet. Ensure the power switch (2) is in the OFF position before connecting.
- Audio Input: Connect your audio source (mixer, instrument, etc.) to the BALANCED INPUT (3) using an XLR or 1/4-inch TRS cable.
- Audio Output (LINK): Use the BALANCED LINK OUTPUT (4) to send the audio signal to another ART 9 series speaker or other audio equipment.
3.4 Initial Power-On
- Ensure all connections are secure.
- Turn the VOLUME knob (5) to its minimum setting.
- Flip the POWER switch (2) to the ON position. The POWER LED will illuminate.
- Gradually increase the VOLUME knob to the desired listening level.
4. Operating the Speaker
4.1 Controls and Indicators
The rear panel (Image 3.2) features the following controls and indicators:
- AC IN (1): Power input connector.
- POWER Switch (2): Turns the speaker ON/OFF.
- BALANCED INPUT (3): XLR/TRS combo jack for audio input.
- BALANCED LINK OUTPUT (4): XLR output for linking to other speakers.
- VOLUME Knob (5): Adjusts the overall output level of the speaker.
- PRESET Selector (6): Cycles through available DSP presets (e.g., Flat, Boost, Stage, Club). Each preset optimizes the speaker's frequency response for different applications.
- LIMIT LED: Illuminates when the internal limiter is active, indicating that the signal is too high and could cause distortion. Reduce the input volume if this LED flashes frequently.
- SIGNAL LED: Illuminates when an audio signal is present at the input.
4.2 DSP Presets (FiRPHASE & Bass Motion Control)
The ART 912-A incorporates advanced DSP features to optimize sound performance:
- FiRPHASE: This proprietary RCF technology optimizes the speaker's phase response, ensuring a coherent and natural sound image across the entire frequency spectrum.
- Bass Motion Control (BMC): BMC manages the woofer's excursion, preventing over-excursion and improving low-frequency linearity and transient response.
Use the PRESET selector (6) to choose the most suitable sound profile for your environment and application. Experiment with different presets to find the best sound for your needs.
5. Maintenance
5.1 Cleaning
- Always disconnect the speaker from the power supply before cleaning.
- Use a soft, dry cloth to wipe down the exterior of the cabinet.
- For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by a dry cloth.
- Do not use abrasive cleaners, solvents, or waxes, as these can damage the finish.
- Keep ventilation openings free of dust and debris.
5.2 Storage
When not in use for extended periods, store the speaker in a dry, cool environment, away from direct sunlight and extreme temperatures. If possible, use the original packaging or a protective cover to prevent dust accumulation and physical damage.
