FAQs
What is the maximum sound pressure level (SPL) the RCF ART 945-A can produce?
The RCF ART 945-A can produce a maximum Sound Pressure Level (SPL) of 135 dB at 1 meter.
What is the frequency response of the ART 945-A?
The frequency response ranges from 45 Hz to 20 kHz.
How do I connect multiple ART 945-A speakers together?
You can link them using XLR or 1/4" cables for audio signal. For power, the Powercon OUT connector on one speaker can be used to power another compatible device, allowing for daisy-chaining power where possible.
What are the benefits of the FiRPHASE and BMC technologies?
FiRPHASE provides transparent sound with absolute clarity and perfect imaging without phase distortions. Bass Motion Control (BMC) is a new advanced woofer excursion management that allows for extended linearity and better sound integrity at the lowest audible frequencies, preventing over-excursions.
Can I use the ART 945-A as a stage monitor?
Yes, the ART 945-A is suitable for stage monitoring. The 'Stage' DSP preset is specifically designed to optimize its performance when used in this configuration, providing a clear and focused sound for performers.
What type of amplifier does the ART 945-A use?
It uses a highly efficient Class-D amplifier, offering 2100W of peak output power.
Does the speaker come with a power cable?
Yes, the ART 945-A includes a Powercon power cable for connecting to an AC power source.
What are the dimensions and weight of the ART 945-A?
The dimensions are 717 mm (Height) x 415 mm (Width) x 410 mm (Depth), and it weighs 22.4 kg.
Troubleshooting
No sound output
Check that the speaker is powered on and the power cable is securely connected. Verify audio cables are properly connected to both the source and the speaker's input. Ensure the volume is turned up and the correct input is selected. Check your audio source for output.
Distorted or clipping sound
Reduce the input signal level from your source or decrease the speaker's volume. Ensure the input signal is not too hot, causing the internal limiter to engage excessively. Check that the DSP preset is appropriate for the source material.
Humming or buzzing noise
Ensure all audio and power cables are properly shielded and grounded. Try using balanced cables (XLR or TRS) for all connections. Test with a different power outlet to rule out electrical interference.
Speaker shuts off unexpectedly
The speaker may have overheated. Ensure adequate ventilation around the unit and that the rear heat exchanger is not blocked. Allow the speaker to cool down before resuming use. Check for any power fluctuations.
Poor bass response
Ensure the 'Flat' or appropriate DSP preset is selected. Check that the woofer is not physically obstructed. Verify the source material has sufficient low-frequency content.
Pros and Cons
Pros
- Exceptional power output (2100W peak) for demanding applications.
- Superior audio clarity and detailed sound reproduction across the frequency spectrum.
- Advanced DSP features like FiRPHASE and BMC enhance sound quality and speaker protection.
- Durable and road-ready construction suitable for frequent use and installations.
- Versatile mounting options for flexible placement in various environments.
- Efficient Class-D amplification with minimal heat generation.
Cons
- The 15" woofer and overall size can be substantial for very compact setups.
- While durable, the polypropylene cabinet may require careful handling to avoid cosmetic damage.
- Requires AC power and appropriate audio cables for operation.
- DSP presets might require further fine-tuning for highly specific acoustic environments.
- Higher price point compared to entry-level PA speakers.
Setup, Compatibility & Care
Setup:
- Power Connection: Connect the speaker to a reliable AC power source using the provided Powercon cable. Ensure the voltage matches your local supply (220-240V). Use the Powercon OUT connector to daisy-chain power to other compatible devices if needed.
- Audio Input: Connect your audio source (mixer, microphone, instrument) to the XLR or 1/4" Jack input connector. Use balanced cables (XLR or TRS) for optimal signal integrity.
- DSP Selection: Choose the appropriate DSP preset (Flat, Boost, Stage) using the rotary control based on your application.
- Volume Adjustment: Set the initial volume level on the speaker and then adjust as needed using the volume control and your source mixer.
Compatibility:
- Inputs: Compatible with standard XLR and 1/4" (6.35mm) audio connectors. Balanced connections are recommended.
- Power: Requires a 220-240V AC power source and uses Powercon connectors. Adapters may be necessary if your power distribution uses different connectors.
- Mounting: Can be mounted on a standard 35mm speaker pole. The M10 mounting points allow for professional rigging via appropriate hardware (not included).
Care:
- Cleaning: Use a soft, damp cloth to clean the exterior. Avoid using harsh chemicals or abrasive cleaners. Ensure the speaker is disconnected from power before cleaning.
- Grille: Keep the steel grille free from dust and debris. A soft brush can be used for light cleaning.
- Storage: Store in a dry environment when not in use. Consider using protective covers for transport.
- Ventilation: Ensure the rear heat exchanger is not obstructed to allow for proper convection cooling.
