About REL manuals on Manuals.plus

REL Acoustics

REL Acoustics focuses solely on creating powered subwoofers without distractions. Their high-fidelity products are designed to transform home theater systems by providing a deep, floor-rumbling foundation of bass. By adding depth and clarity to mid-tones, REL subwoofers expand the entire soundstage to allow main speakers to spring to life.

The REL product lineup includes the Serie S, Serie T/x, Classic series, HT/MKII subwoofers, and innovative AirShip zero-compression wireless transmitters. REL's patented HIGH-LEVEL connection and proprietary filters help integrate their Sub-Bass Systems perfectly with almost any traditional stereo or home cinema speaker array.

REL support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I pair my REL AirShip II transmitter and receiver?

    Turn on both units. If they do not connect automatically, press the momentary 'Pair' buttons on both the transmitter and receiver until the LEDs stop flashing and stay solidly lit.

  • Can I connect my REL subwoofer wirelessly and wired at the same time?

    No. It is not possible to use an AirShip wireless connection and a direct wired connection simultaneously, as this could result in damage and voids the warranty.

  • How should I clean my REL subwoofer cabinet?

    REL enclosures are best maintained by using a light automotive spray-on wax and a microfiber cloth. Do not use dry cloths or abrasive cleaners on the finish.

  • What is the recommended way to connect a REL Sub-Bass System to an amplifier?

    The HIGH-LEVEL connection, using the enclosed secondary cable with the Neutrik Speakon connector, is always the first choice for music systems. This directly feeds the subwoofer the same signal as the main speakers to ensure perfect sonic integration.
