(1) Signal Source Layer
● Multimedia Input: A computer (for music / video audio) is connected to the 16-channel mixer via signal cables (red), supporting lossless audio playback in formats such as FLAC and WAV.
● Vocal Capture: Two sets of UHF-band wireless handheld microphones with strong anti-interference capability, suitable for event hosting, singing and other scenarios. Signals are input to the mixer through signal cables for multi-channel vocal mixing.
(2) Processing and Amplification Layer
● Mixer: 16 input channels support connection of multiple devices (e.g., instrument DI boxes, additional microphones). Volume, equalization (3-band parametric EQ per channel) and panning can be adjusted in real time for preliminary mixing.
● Audio Processor: 2-input 4-output digital processor with built-in feedback suppression algorithm (automatic howling frequency detection and notch filtering) and sound field calibration (venue reflection calculation via software to optimize delay and gain). Outputs to 2-channel power amplifiers for improved sound purity.
● Power Amplifier: High-efficiency Class D amplifier with conversion efficiency ≥ 90%, driving 12-inch stage monitor speakers (frequency response 80Hz–20kHz, sensitivity 98dB) and the VQ110P line array + 18-inch active subwoofer system (audience sound reinforcement, frequency response 35Hz–20kHz, max SPL 138dB).
(3) Sound Output Layer
● VQ110P Line Array: Equipped with 10-inch mid-bass units and 1.75-inch high-frequency compression drivers. Vertical array design (4–8 units stacked per column, coverage angle 90°×120°) ensures SPL attenuation ≤ 6dB per doubling of distance within 100 meters, providing uniform sound coverage for audience areas such as stadium stands and rear sections of outdoor plazas.
● 18-inch Active Subwoofer: Built-in 2000W amplifier, low-frequency extension down to 35Hz, with phase plug technology for enhanced low-frequency impact (ideal for electronic music, rock drum kits). Forms full-band coverage (35Hz–20kHz, ±3dB) with the line array.
● 12-inch Stage Monitor: Near-field monitoring with horn directivity design (120°×60°), providing performers with clear vocal and accompaniment feedback and avoiding stage noise interference.
(4) Power Management
● Power Sequencer: Powers up in the sequence “signal source → processing → amplifiers → speakers” to avoid current surge damage. Features overload / short-circuit protection and adapts to temporary power supplies for mobile performances (e.g., generators, voltage 90–260VAC).
(1) Flexible Stacking for All Scenarios
● Small Events (200–1000 people): 2 sets of VQ110P + 18-inch active subwoofers (1 set left, 1 set right) with 2 pieces of 12-inch monitors. Covers conference rooms and small theaters with SPL 128–132dB, suitable for speeches and band performances.
● Medium Events (1000–5000 people): 4 sets of VQ110P + 18-inch active subwoofers (2 sets left, 2 sets right, 4-high stacking) with 4 monitors. Covers stadiums and open plazas with SPL 134–136dB, ideal for pop concerts and corporate annual meetings.
● Large Events (5000–20000 people): 8 sets of VQ110P + 18-inch active subwoofers (4 sets left, 4 sets right, 8-high stacking) with 6 monitors. Covers main festival stages and stadiums with SPL up to 138dB, delivering clear sound at 100 meters (powerful low end for EDM, penetrating midrange for rock).
(2) Active Design for Rapid Deployment
● Plug-and-Play: Built-in amplifiers in line arrays and subwoofers reduce external amplifiers (traditional systems need 4–8 amps; VQ Series only requires 2 amps for monitors). Wiring time reduced by 50%.
● Lightweight Transport: Single set of VQ110P + 18-inch active subwoofer ≤ 60kg, with flight cases. Suitable for truck transport and on-site rigging (stacking and installation completed within 30 minutes).
(3) Professional Sound Quality & Environmental Resistance
● Waterproof & Dustproof: VQ Series loudspeakers feature IP54 rating (rain/dust proof) for outdoor shows. Polyurea coating enhances durability, UV and salt spray resistance (ideal for coastal events).
● Phase Fidelity: Coaxial driver design with phase difference ≤ 1°, ensuring clear vocal imaging (sound centered on stage) and improved immersive experience.
(1)Excessively high sound pressure levels in the near field, causing listener fatigue, while insufficient sound pressure in the far field leads to weak and distorted audio;
(2)Formation of coverage voids in upper stands, walkways and other critical zones;
(3)Sound pressure level variations across the entire venue exceeding 3 dB, which fails to meet relevant specifications and cannot guarantee a consistent and uniform auditory experience for all spectators.
