the rules of sound MONITOR SPEAKER
MQ 30P TWO-WAY MINIATURE MONITOR SPEAKER SYSTEM The MQ30P is an orientable two-way mini-speaker. The components are a 3” woofer and a coaxial dome tweeter that ensure a wide angle of coverage. Combined with a subwoofer, the MQ30P allows high quality music distribution with high output levels. An important feature of the MQ30P is that it provides consistent reproduction of all the frequencies involved in voice transmission and therefore, alone or in combination with a subwoofer, makes it possible to obtain a high level of vocal intelligibility The MQ30P has been designed to adhere closely to the wall or ceiling and thus it has a limited protrusion. The built-in hinged support makes the speaker easy to install and orient in any direction. Like the other Monitor Q products, MQ 30P installation is simple and flexible. First, the support is mounted on the wall and the connector is wired; then, when the premises is completely furnished, the installation, orientation, and connection of the mini-speaker are immediate. The speaker can be connected to constant voltage audio lines at 70 V or 100 V or to constant impedance lines (switch positioned to 16 Ohm).
