2. PRESETS Button: Cycles through different DSP presets (LINEAR, BOOST, STAGE) to optimize sound for various applications.
3. LINEAR LED: Indicates the 'Linear' preset is active, providing a flat frequency response.
4. BOOST LED: Indicates the 'Boost' preset is active, enhancing bass and treble frequencies.
5. STAGE LED: Indicates the 'Stage' preset is active, optimized for stage monitoring applications.
6. VOLUME Knob: Adjusts the overall output level of the speaker.
7. OVERLOAD LED: Illuminates when the input signal is too high, indicating potential clipping. Reduce input level if this LED lights up consistently.
8. SIGNAL LED: Illuminates when an audio signal is present at the input.
9. POWERCON TRUE1 Input: Secure power connector for AC mains input.
10. POWERCON TRUE1 Link: Power output to link power to another speaker.

5. Setup

5.1. Placement

The RCF Art 945-A speaker can be used in various configurations:

• Pole Mounting: Insert the speaker onto a standard 35mm speaker pole or tripod stand using the integrated pole mount socket on the bottom of the speaker. Ensure the stand is stable and rated for the speaker's weight (approximately 49.3 lbs / 22.4 kg).
• Floor Placement: The speaker can be placed directly on a flat, stable surface. The rubber feet on the bottom provide stability and isolation.
• Stage Monitor: The cabinet design allows for use as a stage monitor. Position the speaker on its side with the appropriate angle for monitoring.
• Wall Mounting: Utilize the provided vertical mount bracket for secure wall installation. Ensure the wall structure can support the speaker's weight.

5.2. Power Connection

1. Ensure the speaker's VOLUME knob is set to minimum (fully counter-clockwise).
2. Connect the supplied Powercon TRUE1 power cable to the POWERCON TRUE1 Input on the rear panel of the speaker.
3. Connect the other end of the power cable to a suitable AC mains outlet. Verify that the voltage matches the speaker's requirements (e.g., 100-120V or 220-240V).
4. If linking power to another speaker, use a Powercon TRUE1 link cable from the POWERCON TRUE1 Link output to the input of the next speaker.

5.3. Audio Connections

1. Connect your audio source (e.g., mixer, audio interface) to the BALANCED INPUT (XLR) on the rear panel using a balanced XLR cable.
2. If connecting multiple speakers in a daisy chain, use an XLR cable from the BALANCED LINK output of the first speaker to the input of the next speaker.

6. Operating

6.1. Powering On/Off

1. Before powering on, ensure all connections are secure and the VOLUME knob is at its minimum setting.
2. Locate the power switch (typically near the power input) and switch it to the 'ON' position. The power LED on the front of the speaker will illuminate.
3. To power off, set the VOLUME knob to minimum, then switch the power switch to 'OFF'.

6.2. Volume Control

The VOLUME knob on the rear panel controls the output level of the speaker. Slowly turn the knob clockwise to increase the volume to the desired level. Monitor the OVERLOAD LED to prevent clipping.

6.3. Preset Selection

The PRESETS button allows you to select between three different DSP modes:

• LINEAR: Provides a flat frequency response, suitable for general sound reinforcement where a neutral sound is desired.
• BOOST: Enhances low and high frequencies, often used for music playback or when a more pronounced bass and treble response is needed.
• STAGE: Optimized for use as a stage monitor, providing clarity and feedback suppression for performers.

Press the PRESETS button repeatedly to cycle through these modes. The corresponding LED (LINEAR, BOOST, or STAGE) will illuminate to indicate the active preset.

6.4. Signal and Overload Indicators

• SIGNAL LED: This green LED illuminates when an audio signal is detected at the input. It indicates that the speaker is receiving an audio signal.
• OVERLOAD LED: This red LED illuminates when the input signal level is too high, causing the amplifier to clip. If this LED lights up frequently or stays on, reduce the input level from your source or the speaker's VOLUME knob to prevent distortion and potential damage.

7. Maintenance

7.1. Cleaning

To maintain the appearance and performance of your speaker:

• Disconnect the speaker from the power supply before cleaning.
• Use a soft, dry cloth to wipe down 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 harsh chemicals, as these can damage the finish.
• Keep the grille free of dust and debris to ensure proper sound dispersion.

7.2. Storage

When not in use for extended periods:

• Store the speaker in a cool, dry place, away from direct sunlight and extreme temperatures.
• If possible, use the original packaging or a protective cover to shield the speaker from dust and physical damage.
