AC Connectors

M3D, M3D-Sub and MILO:
These models may be ordered with 250 V NEMA L6-20 twist lock male inlet , IEC 309 male inlet AC connectors. They can also be ordered with VEAM all-in-one connector and accompanying multi cables, breakout cables and interface modules. VEAM combines audio input, AC, and network connection for true plug-and-play operation.

M2D and M2D-Sub:
These models come standard with a locking PowerCon AC connector. They can also be ordered with VEAM all-in-one connector.

M1D and M1D-Sub:
These models come standard with PowerCon connectors with looping output. No optional AC connectors are available for these models.

Audio Connectors

All standard audio input connectors are XLR. A female XLR input and a hardwired male XLR loop output are provided.  These XLR connectors remain available in loudspeakers fitted with VEAM.

Weather Protection

M2D Rain Hood

M Series loudspeaker cabinets are constructed of premium birch plywood. To protect the cabinets the company employs a variety of innovative manufacturing techniques and processes. However, weather-protected versions are available on special order.

A major part of the weather protection procedure involves treating the wood before assembling the cabinet This modern, sophisticated treatment is applied to all wooden parts of the cabinet. The proprietary sealant penetrates and stabilizes the wood, enabling the cabinet to withstand a wide range of temperature and humidity conditions. The exterior topcoat is a two-part modified paint similar to that used in military applications.

An accredited, independent laboratory has tested this process according to protocols established by ASTM International, an international standards body. The sealant coat and topcoat were tested for dry film thickness, wet film thickness, pencil hardness, impact resistance, water absorption, water resistance, dry adhesion, solvent resistance and specular gloss. In addition, the topcoat was also tested for abrasion resistance and biological resistance, subjected to intense xenon arc light exposure and put through numerous freeze/thaw cycles.

Cone drivers are coated with a special water-resistant material, while corrosion-resistant gold-plated connectors assure reliable connections. Grill frames are subject to an anti-corrosion treatment and then coated to resist moisture. A fine mesh or protective grille foam, or a combination of both is applied to the grille to help prevent rain intrusion. Stainless steel fasteners and custom gaskets are used for all components mounting to the cabinet. In some cases, water accumulation is prevented by providing drainage holes in the cabinet lips.

Meyer Sound circuit boards have been tested to military specifications by an independent laboratory, including testing for salt invasion. A collapsible or fixed rain hood, made of heavy-duty fabric or plastic, protects the electronics package from rain.

All of these measures make Meyer Sound weather-protected loudspeakers the most durable and reliable products in the industry. They will provide extended service in all environmental conditions.

Finish / Custom Painting

All M Series enclosures, rigging and grids can be painted to match standard RAL or Pantone specification.
