Please read and understand all safety instructions before operating this product. Retain this manual for future reference.

• Power Source: Connect the unit only to a power supply of the type described in this manual or marked on the unit.
• Grounding: Ensure the power cord is properly grounded to prevent electric shock. Do not defeat the safety purpose of the polarized or grounding-type plug.
• Ventilation: Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
• Heat: Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
• Water and Moisture: Do not use this apparatus near water or moisture. This product is not waterproof.
• Cleaning: Clean only with a dry cloth.
• Servicing: Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
• Hearing Protection: Prolonged exposure to high sound pressure levels can cause permanent hearing damage. Use caution when setting volume levels.

3. Unpacking and Inspection

Carefully unpack your Cerwin Vega CVE-18s subwoofer and inspect it for any signs of damage that may have occurred during transit. If any damage is found, contact your dealer immediately.

4. Setup

4.1 Physical Placement

The placement of your subwoofer significantly impacts sound quality. Consider the following:

• Corner Placement: Placing the subwoofer in a corner can enhance bass output due to room acoustics.
• Wall Placement: Placing it against a wall can also boost bass, though less dramatically than a corner.
• Open Space: Placing it away from walls and corners may result in less bass reinforcement but potentially more accurate low-frequency response.
• Stability: Ensure the subwoofer is placed on a stable, level surface to prevent vibrations and movement during operation.

4.2 Connections

The CVE-18s features a rear panel with various inputs and outputs for connecting to your audio system.

1. Power Connection: Connect the supplied power cord to the AC inlet on the rear panel and then to a grounded electrical outlet.
2. Audio Input: Use XLR or 1/4" TRS cables to connect your audio source (mixer, preamplifier, etc.) to the CH 1 INPUT and/or CH 2 INPUT jacks.
3. Audio Output: If connecting to full-range speakers, use XLR cables from the CH 1 OUTPUT and/or CH 2 OUTPUT jacks to the inputs of your main speakers. These outputs provide a high-pass filtered signal (100Hz HPF) when selected, or a full-range signal.

4.3 Bluetooth Pairing

The CVE-18s allows audio streaming via Bluetooth from any smartphone or tablet.

1. Ensure the subwoofer is powered on.
2. Activate Bluetooth on your smartphone or tablet.
3. Press and hold the "PAIR PUSH LINK HOLD" button on the rear panel of the CVE-18s until the Bluetooth indicator light begins to flash.
4. On your device, search for "CVE-18s" in the list of available Bluetooth devices and select it to pair.
5. Once paired, the Bluetooth indicator light will remain solid, and you can stream audio to the subwoofer.
6. For stereo pairing with another CVE speaker, refer to the Quick Start Guide for detailed instructions.

4.4 DSP Modes

The CVE-18s features two easy-to-use DSP-driven modes to tailor your sound:

• LIVE PA: Optimized for live sound reinforcement, providing a balanced low-frequency response suitable for various instruments and vocals.
• CLUB/DJ: Enhances bass impact and punch, ideal for music playback in DJ sets and club environments.

Select the desired mode using the "DSP MODE SELECT" button on the rear panel.

5. Operating Instructions

5.1 Power On/Off

1. Before powering on, ensure all connections are secure and the LEVEL knob is set to its minimum position.
2. Flip the POWER switch on the rear panel to the "ON" position. The power indicator light will illuminate.
3. To power off, set the LEVEL knob to minimum, then flip the POWER switch to the "OFF" position.

5.2 Level Control

The LEVEL knob on the rear panel controls the overall output volume of the subwoofer.

• Start with the LEVEL knob at its minimum setting.
• Gradually increase the LEVEL to achieve the desired bass output, ensuring it blends well with your main speakers without distortion.
• Monitor the LIMIT indicator light. If it flashes frequently or stays lit, reduce the LEVEL to prevent clipping and potential damage.

5.3 Output Mode Selection

The "OUTPUT SELECT" button on the rear panel allows you to choose the signal sent to the XLR outputs:

• 100Hz HPF (High-Pass Filter): Sends a signal with frequencies below 100Hz removed to your main speakers. This is recommended when pairing the subwoofer with full-range speakers to optimize their performance and prevent them from reproducing low frequencies handled by the subwoofer.
• FULL RANGE: Sends the full frequency range signal to your main speakers. Use this if your main speakers have their own crossover or if you prefer a full-range signal.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your CVE-18s subwoofer.

• Cleaning: Disconnect the power before cleaning. Use a soft, dry cloth to wipe the exterior surfaces. Do not use abrasive cleaners, solvents, or waxes.
• Ventilation: Keep ventilation openings clear of dust and debris.
• Storage: If storing the subwoofer for an extended period, place it in its original packaging in a cool, dry environment, away from extreme temperatures and humidity.
• Inspection: Periodically check the power cord and audio cables for any signs of wear or damage. Replace damaged cables immediately.
