Ruoca Audio
Enterprise-grade acoustic transmission hardware engineered for broadcast, conference, performance, and pro-audio deployments.
Enping Ruoca Electronics Co., Ltd. is a distinguished, professional microphone and speaker manufacturer headquartered in Enping, Guangdong, China—widely recognized as the international heartland of electroacoustic engineering. Since our inception, we have dedicated our industrial infrastructure to designing, engineering, and manufacturing ultra-reliable, high-fidelity audio transmission solutions.
Our solutions cater across extensive professional ecosystems, including live concert stages, professional houses of worship, corporate conference suites, educational institutions, broadcast studios, and high-density commercial karaoke setups.
Operating as an integrated Research and Development (R&D), production, and global sales enterprise, Ruoca Electronics maintains rigorous end-to-end control across the acoustic lifecycle. From initial PCB circuit schematics and digital signal processing (DSP) algorithms to robotic SMT assembly, structural tooling, and final acoustic chamber calibration, we ensure unmatched acoustic fidelity.
Why Tier-1 international pro-audio brands, global distributors, and private-label integrators select Enping Ruoca Electronics as their foundational OEM/ODM audio partner.
Our in-house acoustic engineering corps continuously pioneers breakthroughs in sound clarity, Phase-Locked Loop (PLL) synthesizer stability, and total harmonic distortion (THD < 0.5%) reduction. Through state-of-the-art RF spectrum simulation, we engineer transmission units that thrive in crowded 2.4GHz and UHF wireless spectrums without packet dropouts.
Every single unit undergoes rigorous multi-stage validation: automated anechoic chamber testing, RF sweep monitoring, environmental temperature drop chambers (-20°C to 60°C), and drop impact stress testing. We utilize high-grade neodymium (NdFeB) magnetic structures, gold-sputtered condenser diaphragms, and military-spec zinc-aluminum alloy chassis.
We provide deep-level brand customization: high-precision laser engraving, structural tooling changes, bespoke DSP voicing profiles, unique industrial frequency bands, and custom retail packaging. Flexible Minimum Order Quantities (MOQs) allow scalable entry for disruptive brands and established audio distributors alike.
By producing CNC metal enclosures, injection-molded chassis, transformers, and automated SMT boards within our Enping industrial cluster, we eliminate unnecessary middlemen. Clients benefit from unmatched unit-cost economics, aggressive price-to-performance metrics, and consistent production lead times.
We hold verified ISO 9001, CE, FCC, and TCB certifications. All transmitters and wireless microphone components comply with international RF spectrum regulations, RoHS material environmental directives, and WEEE standards, expediting seamless custom clearance for worldwide delivery.
Supported by sophisticated ERP integration, Ruoca maintains a robust buffer stock of key IC chipsets and RF filters. This allows us to guarantee reliable delivery windows, rapid prototyping turnaround in as little as 14 days, and uninterrupted supply even amid fluctuating global logistics landscapes.
Our facility houses high-speed surface mount technology (SMT) lines capable of micro-pitch placement, ensuring absolute reliability for wireless transmitter circuit boards. By automating complex solder operations, we mitigate RF crosstalk, suppress parasitic capacitance, and guarantee optimal signal-to-noise ratios across all microphone transmitters.

Our OEM Synco-compatible transmitters leverage advanced Phase-Locked Loop (PLL) synthesized tuning. Operating across switchable UHF channels or secure 2.4GHz ISM bands, the transmitter monitors spectrum congestion and executes seamless channel reallocation. The implementation of anti-interference frequency hopping protocols protects critical vocal capture from mobile cellular spillover, Wi-Fi 6 clutter, and digital broadcast intermodulation.
Conventional wireless transmitters introduce audible "breathing" artifacts through heavy analog companding. Our latest generation digital wireless hardware implements high-resolution 24-bit/48kHz ADC conversion with ultra-low latency audio codecs (< 2.8ms). This ensures an ultra-wide dynamic range (> 105dB), allowing performers and speakers to transmit whispers or powerful vocal peaks without clipping or high-frequency degradation.
Handheld and bodypack transmitters must balance RF output wattage (switchable between 10mW and 30mW) with extended operational longevity. Ruoca’s proprietary power circuitry utilizes high-efficiency switching regulators and lithium-polymer charging ICs, delivering up to 10 hours of continuous field operation while dissipating minimal thermal energy through lightweight aluminum alloy structural housings.
Paired with our rackmount and portable dual receivers, our transmitters leverage dual-antenna diversity decoding. The circuit actively evaluates incoming signal strength (RSSI), instantaneously selecting the cleanest RF path to eliminate dead spots, phase cancellation, and multipath interference in high-reflective environments like auditoriums and broadcast soundstages.
