Featuring high utilization frequency and diverse performance scenarios, the theater sets stringent professional standards for the sound quality, sound field coverage and operational stability of sound reinforcement equipment.

The theater’s original sound equipment had been in service for years with prominent defects. Significant sound differences existed among front, rear and corner seats, resulting in unclear sound and insufficient vocal penetration for rear audiences. In addition, the outdated devices were prone to noise, sound interruption and malfunctions during prolonged operation, which constantly undermined performance effects and failed to meet professional stage sound reinforcement standards. To comprehensively improve theater performance quality and build an immersive acoustic environment, the theater officially launched the sound system upgrading project.

After evaluating multiple sound equipment brands, the client finally selected our professional sound reinforcement products by comprehensively assessing acoustic debugging performance, hardware quality, long-term operational stability and overseas project service capabilities. The core goal was to completely solve on-site problems including uneven sound field, poor sound quality and frequent equipment failures, ensure every audience in the venue can hear stage sound clearly and immersively, and comprehensively upgrade the overall theater viewing experience.

2. Client Requirements

Combined with the venue structure and high-frequency operation characteristics of the 1000-seat indoor theater, the client put forward two core requirements together with high standards for equipment adaptability and professionalism.

1. Full-venue Clear Sound Reinforcement: The theater features a large indoor space and dense seating layout covering central, corner and remote rear areas. The sound system needs to eliminate acoustic blind spots thoroughly, enabling all 1000 audiences to clearly capture stage vocals and instrumental sounds regardless of seating positions. It is required to deliver transparent vocals, delicate sound quality and balanced high and low frequencies to adapt to various stage performances such as dramas and stage plays.

2. Long-term Stable Operation: Single theater performances and rehearsals can last for several hours with dense daily exhibitions. The sound system must support long-hour high-power operation without sound interruption, noise, overheating or shutdown failures, reducing equipment failure rates and subsequent maintenance costs to guarantee sustainable daily theater operation.

Besides, the client required the sound equipment to fit the acoustic environment of indoor theaters with excellent noise reduction and high sound field restoration, so as to maximally restore the original sound of stage performances and build a professional high-end theater sound reinforcement system.

3. Our Solution

Based on the on-site size, indoor acoustic structure and core operational pain points of the Italian 1000-seat indoor theater, our technical team conducted on-site surveys and formulated a customized professional sound reinforcement solution complying with indoor stage acoustic standards, adopting a combined system of 8 K210 line array speakers and 4 KS28 subwoofers.

As the main sound reinforcement devices, K210 line array speakers adopt advanced sound wave directional control technology to accurately cover all seating areas of the theater. The devices effectively compensate for indoor sound wave reflection and attenuation, solving the traditional problems of uneven sound field and blurred remote sound, and ensuring consistent and clear sound quality across front, rear and corner areas. Matched with 4 KS28 subwoofers for auxiliary sound reinforcement, the system supplements low-frequency sound effects, enriches sound field layers and creates a three-dimensional acoustic atmosphere suitable for diverse stage performance scenarios.

With upgraded hardware and optimized acoustic calibration, the entire system is tailored for long-term high-intensity indoor use. On-site tests verify stable 12-hour uninterrupted high-power operation without failures, fully meeting the theater’s demand for long-hour and high-frequency performances. Furthermore, our technical team accurately arranged equipment installation positions, suspension angles and output parameters according to indoor wall structures, floor heights and spatial layouts to avoid indoor echo and noise interference and restore pure original stage sound.
