Stadiums

Housed in a convenient 2U package, the MA6.8Q 4-channel amplifier allows for the adjustment of maximum voltage peak, gain adjustment and has on-board network capability for monitoring and control. With these features it is now possible to specify identical amplifiers in an installation and then adjust each output to the very specific requirements of the speaker system. A typical large-scale system is a combination of high-powered speakers, full range in-fill speakers, 70/100V ceiling speakers, with an active speaker management system. With switchable outputs and on-board network capabilities, the MA6.8Q can be designed into a complete value engineered system handling all amplification tasks.

MA6.8Q specifications

The Martin Audio MA6.8Q is a versatile and powerful compact loudspeaker system designed for a range of professional audio applications. With its exceptional sound quality and innovative features, it has earned a solid reputation in the live sound, installation, and outdoor event markets.

At the heart of the MA6.8Q is its coaxial design, featuring a 6.5-inch low-frequency driver complemented by a 1-inch high-frequency compression driver. This design allows for a highly efficient and coherent sound reproduction across the entire frequency spectrum. The coaxial configuration enables the system to deliver superior phase coherence and reduced time alignment issues, resulting in clear and accurate audio playback. This makes it an excellent choice for environments where intelligibility is paramount, such as conference centers, theaters, and houses of worship.

One of the standout features of the MA6.8Q is its flexible mounting and rigging options. It is equipped with a range of mounting points and accessories that facilitate easy installation and orientation, whether in a fixed installation or for portable use. This flexibility allows the loudspeaker to be configured for a variety of setups, from handheld use on a stand to installation in complex sound reinforcement systems.

The MA6.8Q also integrates advanced technology to enhance its performance. It comes with a built-in passive crossover that ensures optimal frequency distribution between the drivers. This eliminates the need for external crossovers and simplifies system setup. Additionally, the loudspeaker is designed to handle high power levels, making it suitable for both small and large scale events without compromising audio quality.

Durability is another hallmark of the MA6.8Q, built with a robust enclosure that combines lightweight materials with structural integrity, ensuring it can withstand the rigors of touring and various environments. It features a weather-resistant design, making it applicable for outdoor events, and its compact form factor makes it easy to transport.
