Q118 is a single 18 inch medium and low active line array speaker

1.Q118 is a direct-shooting subwoofer with full flexibility at low frequencies and greater dynamic range, which makes this series of products more perfect. Beilarly engineers match this series to the full frequency of the most ideal frequency response design 12 "Their combination can achieve a very smooth and smooth frequency advantage, and the connection is very accurate.

2.Q118 adopts a rectangular box of 18% birch plywood, with polyester black pearl-point paint on the surface to achieve the functions of waterproof, sun protection, wear resistance, protection and modification. The high-power speaker design can better meet the uniformity and sound pressure level of the sound field. At the same time, it is recommended that users choose 8 ohm / 1000W power amplifier to match the use, so that the Q118 is more powerful and exerts the best results.

This is a compact and powerful high-voltage switch-mode amplifier module designed to drive high-impedance loads, capable of providing 700 W @ 8Ω per channel or 1400 W @ 16Ω in bridge mode, it provides high clean output power due to the previous generation of compact PFC power supplies, The new power supply design uses power factor correction (PFC) technology, which not only reduces power consumption (less than 0.55 W in standby), but also improves system reliability and consistency under all operating conditions. The high efficiency of the output stage improves the overall performance, bringing natural power and a pure output signal.

Maintain high performance and stability anytime, anywhere. The switching mode is stable, reliable and attention to detail. The Pulse Width Modulation (PWM) section has been precisely designed to bring unmatched audio performance, ensuring that the module is protected from intermodulation components in multi-channel applications. Optimized performance and minimized power consumption. Automatic power supply voltage selector, to achieve universal operation, the latest generation of single-stage power factor correction technology (PFC). 0.5 W low standby power complete protection. Thermal shutdown, short-circuit and overload protection, permanent high-frequency protection, compact, power supply, output stage and connectors are integrated in a compact, lightweight box.
