Operating Instructions — 750-LFC
Compact Low-Frequency Control Element
Meyer Sound’s 750-LFC very compact low-frequency control element reproduces low frequencies at high, continuous output levels with extremely low distortion. The 750-LFC offers the same sonic linearity as Meyer Sound’s 900-LFC low-frequency control element in a smaller, lighter cabinet, making it ideal for building scalable systems to suit portable applications or fixed installations of any size.
750-LFC Compact Low-Frequency Control Element
The 750-LFC subwoofer effectively complements LINA arrays in the lower end of the spectrum with exceptional low-frequency headroom. With an incredible power-to-size ratio for such a compact cabinet, the 750-LFC is the LINA loudspeaker’s ideal and extremely versatile companion.
In addition to pairing with LINA systems, the 750-LFC integrates easily with other Meyer Sound loudspeaker systems, including LEOPARD, ULTRA-X40 and other UltraSeries loudspeakers.
A newly designed class D amplifier affords unprecedented efficiency to the 750-LFC, significantly lowering distortion while reducing power consumption and operating temperature. A single, field-replaceable module contains the onboard amplifier and control circuitry.
LINA and 750-LFC loudspeakers can be driven by Meyer Sound’s Galileo GALAXY Network Platform, which provides matrix routing, alignment, and processing for array components. LINA and 750-LFC loudspeakers also work with Meyer Sound’s RMS remote monitoring system, which enables comprehensive monitoring of system parameters from a Mac® or Windows®-based computer.
Note
To guarantee optimum performance, use Meyer Sound’s MAPP software to design systems with the 750-LFC.

The 750-LFC is available with or without Meyer Sound’s QuickFly® rigging. When equipped with the optional MRK-750 rigging kit, the 750-LFC cabinet’s captive GuideALinks allow it to be flown from the MG-MINA/LINA/750-LFC multipurpose grid in LINA/750-LFC arrays without any transition frame between the 750-LFC and LINA loudspeakers (shown in the figure above on the left). The MG-MINA/LINA/750-LFC grid can also be used to create a wider base for groundstacks (shown in the figure above on the right).
750-LFC loudspeakers can be flown separately as a subwoofer array with variable splay angles from 0° to 5°. It is also possible to configure the 750-LFC loudspeaker in cardioid arrays to reduce output behind the loudspeakers.
Optional MCF-750 caster frames are available for transporting the 750-LFC loudspeaker in stacks. The caster frame comes in two versions (for loudspeakers equipped with the rigging kit or not). Please specify the appropriate caster frame version when placing an order.
The 750-LFC integral pole mount facilitates the placement of one or two LINA loudspeakers on top of a pole using the
MUB-LINA (shown in the figure below) or MYA-LINA yoke. In addition, the pole mount can be used to pair the 750-LFC with the ULTRA-X40 and other UltraSeries loudspeakers.
