On July 4, 2026, the Guojiao 1573 Grand Theater, located in Jiangyang District, Luzhou City, Sichuan Province, officially kicked off its opening performance season, featuring a diverse array of art forms including concerts, dance dramas, plays, operas, and children's theater. The theater is part of the Jiangyang District Cultural and Sports Center, and its audio system is built upon the flagship series of Yamaha digital mixing consoles, enabling high-quality, reliable end-to-end signal transmission and processing workflows. This provides a stable and immersive auditory experience for the theater's varied productions, thereby helping Luzhou's cultural tourism sector establish a new benchmark for performing arts in southern Sichuan.

Today, let us step into the “sonic heart” of this theater and uncover how the RIVAGE PM5 digital mixing system, the DM7 digital mixing console, and the Rio3224-D3 interface box work together to form a comprehensive flagship-class audio matrix.

Chapter 1: RIVAGE PM5 – The 'Smart Brain' of the Master-Class Mixing System

SWS Provide technical support

As one of the core members of the Yamaha RIVAGE PM series, the PM5 (control surface model: CS-R5) is a digital mixing system purposebuilt for premier live sound reinforcement. At the Guojiao 1573 Grand Theater, it serves as the central hub for overall audio master control.

Flagship processing capability: 

This PM5 system is equipped with the DSP-RX-EX processing engine, capable of handling 288 input channels, 72 mix busses, and 36 matrices. This enables it to effortlessly manage the vast number of audio channels required for complex productions such as symphonies, operas, and large-scale gala events.

Intuitive and efficient control: 

The console control surface is equipped with three 15-inch touchscreens and three bays (with a total of 36 faders). Leveraging ergonomic principles, the touchscreens are positioned closer to the user for more convenient operation. The surface features a lightweight design, weighing only 42 kg, yet packing immense power.

Carrying on the Legacy, Continuing the Legendary Sound Quality:

The Yamaha RIVAGE PM series carries on the legendary sound quality of numerous classic models, while integrating a host of industry-renowned top-tier third?party plugins, including Bricasti reverb effects, Eventide effects, RND Portico processors, and Dan Dugan auto-mixers. Combined with the self-developed DaNSe high-efficiency noise suppressor, it offers over 50 effects and formidable processing power. From theaters to stadiums, it flexibly meets a wide range of acoustic challenges, granting sound engineers ample creative freedom while delivering pure, stable, and immersive auditory experiences.

Chapter 2: DM7 – The Flexible and Powerful "All-Round Partner"

Complementing the PM5 in every way is Yamaha’s new-generation DM7 digital mixing console. Equipped with Dante networking, this versatile digital mixer takes on the critical tasks of flexible signal routing and precise monitoring mixing within the theater.

Powerful channel capacity: 

The DM7 provides 120 input channels, 48 mix busses, and 12 matrices, more than capable of meeting the demands of any scenario—from a theatrical monologue to a hundred-piece orchestra.

96kHz High Sampling Rate: 

The DM7 operates at 96kHz to deliver exceptional sound quality, with signal latency below 1.5ms, ensuring that every sonic nuance is conveyed to the audience in real time and with pinpoint accuracy.

Human-centric interactive design: 

The DM7 is equipped with 24+4 faders and two 12.1-inch plus one 7-inch multi?touch screens, featuring an intuitive user interface that allows sound engineers to get up to speed quickly. A built-in redundant power supply ensures fail-safe operation during performances.

Chapter 3: Rio3224-D3 Series Interface Box – The Stable and Reliable "Signal Artery"

No matter how powerful a mixing console may be, it still requires pure and stable signal transmission. The Guojiao 1573 Grand Theater has chosen the Yamaha third-generation Dante?compatible I/O interface box—the Rio3224-D3.

Massive I/O configuration: 

It provides 32 analog inputs, 16 analog outputs, and 8 digital AES/EBU outputs, easily connecting to a wide variety of microphones and instruments on stage.

Comprehensive sound quality evolution: 

Compared to previous generations, the third-generation Rio3224-D3 achieves lower noise levels and a wider dynamic range, faithfully capturing every note and every line of dialogue on stage.

Convenience features: 

The Rio3224-D3 adds a headphone jack, allowing engineers to directly check input/output audio locally; each output port is equipped with delay, phase, and level adjustment functions; the dual redundant power supply design ensures extreme system reliability; and power consumption is reduced by 16% compared to the previous generation, making it more energy-efficient and environmentally friendly.

Chapter 4: A Powerful Synergy – Creating Luzhou’s New Cultural Calling Card

Together, the RIVAGE PM5, DM7, and Rio3224-D3 form an end-to-end top-tier audio system for the Guojiao 1573 Grand Theater, covering everything from signal acquisition and processing to transmission. The flagship PM5 takes charge of main PA control, while the DM7 flexibly handles diverse mixing needs, and the Rio3224-D3 ensures efficient connectivity across all devices via the Dante networking protocol. Whether applied to large-scale galas, theatrical performances, or a variety of cultural events, this system consistently delivers outstanding sound quality, rock-solid reliability, and intuitive operation, offering audiences an immersive listening experience. Sound is the bridge that connects artists and audiences. Backed by SWS for system design and technical support, the Guojiao 1573 Grand Theater, in partnership with Yamaha, uses world?class sonic excellence to strike a powerful chord for the city's cultural renaissance.
