USER MANUAL MERO6 Audac

6" High-end in-wall speaker

The MERO speakers will blend beautifully into any interior, making only their extraordinary sound draw your attention with their nearly invisible design. Their slim grill with very thin border of only 1mm and limited grill depth extrudes the surface by only 3.2 mm when installed.

Their grilles are retained by neodymium magnets which enables assembly in seconds, while powerful enough to keep it fixed, even when subject to vibrations or if touched. Their applications range from residential Hi–Fi and home cinema installations to Multi–Zone systems, unobtrusive installations in lounges, bars, boutiques and offices.

The selection of high-grade materials in combination with accurate acoustics craftsmanship makes the MERO speakers superior in their class. The largest MER06 consists of a 6" aluminum cone woofer and complementary 1" dome tweeter that are smoothly matched and optimized using a high-quality crossover network.

An acoustically optimized waveguide matches the dispersion of woofer and tweeter, while a phaseplug reduces diffraction and enhances off-axis high frequency response. All these details share their part to its pure sound.

An elegant look with minimal visual impact is created by the slim grill with very thin border, while great ease and installers convenience is guaranteed using the quick-fix mechanism with Gold-CON connectivities. Installation can be done in both vertically and horizontally, while the rotatable tweeter allows optimal orientation positioning.

Installing the MERO

Introduction

The MERO speakers feature a quick-fixing mechanism, which allows quick and easy installation of the loudspeakers in only a few minutes.

The installation of the MERO speakers requires a minimum amount of installation skills. Before the loudspeaker is installed, the location whereto it will be mounted should be carefully checked to make sure the surface can support the weight of the speaker and no lines for water, gas, electricity or other supplies are crossing this point.

Installation procedure

To ensure a safe and secure mounting of the loudspeaker, the installation should be done according to the procedure described below:

1) Firstly cut a hole into the surface where to the loudspeaker should be installed with dimensions 254 x 174 mm. The included cutout template can be used for an easy marking of the installation hole.

2) Provide the loudspeaker connection cable through the mounting hole. Make sure the used connection cable is sufficiently thick. The required cable thickness depends on its length.
3) Take the loudspeaker, and remove the front grill which is held in place by neodymium magnets. The front grill can be easily removed by gently pulling it.

4) Connect the loudspeaker connection cable to the gold plated spring clamp connectors. Press the button of the corresponding terminal down and insert the connection cable. After releasing the button, the cable is connected to the loudspeaker. The Red terminal indicates positive (+) pole and the Black terminal indicates the negative (−) pole.

Mind the polarity markings when wiring the loudspeaker cables.

Maintain the same polarity and wiring colour coding throughout the entire system to avoid any mistakes causing malfunction or distortion.

5) Once the connections are made, the loudspeaker can be installed in the provided mounting hole. Make sure the mounting clips of the loudspeaker are rotated inwards, making the speaker fit through the hole. Insert the speaker through the provided mounting hole, and use a screwdriver for tightening the fixing screws.

Once the screws are tightened a quarter turn, the mounting clip will rotate outwards and will be locked behind the surface. From then on, the loudspeaker is anchored in the surface and thus can not fall.

6) After the screws are tightened and the speaker is level with the surface, the front grill can be assembled to the loudspeaker.
