M3000 high-frequency module has two types: m3000a and m3000d, with different frequency band. The module consists of transmitting voice signal, modulation, power amplification, noise amplification, voice signal demodulation and signals procession. It begins to work normally by simply adding an external mcu, an audio amplifier, a mic (microphone) and a speaker.
The module is with small volume. It is easy to develop within short period. It could be made into small walkie-talkie, and be used in other mobile handheld devices. It is practical and easy to use, and may be widely used in gifts, catering, tourism and other industries.

Dual-channel design, two Handheld (or Lapel) wireless microphone can be used together without interference. High-precision quartz crystal locked frequency. Looking noise to solve the problem of noise interference which is hard for general wireless receiver to overcome. High sensitivity and high S/N ratio, long receiving distance, and never staccato, never wander. Built-in noise reduction compress-expand circuit. Excellent selectivity, multi-channel simultaneously, without mutual interference. Standard metal casing, avoid interference effectively. Most suitable for Studio,Karaoke,Broadcast etc. Operating distance is up to 50 meters in ideal environment and 30-40 meters in the complex environment. Product Features: VHF220-270MHz wave band Frequency Response: 60Hz-16KHz3dB SNR:>90dB frequency stability:0.005% Output power:0-400mV T.H.D
Description and Application W-210A is a line array speaker which is made of two 10'' neodymium woofers, two 2'' titanium neodymium compression drivers and high-performance low-distortion compression driver with innovative horn design of waves phase philosophy. It is a zero interfere line array with multi- speaker combined to produce accurate directivity and maximum dynamic impact. Wherever low frequency extension is required, a W-210A will integrate seamlessly with W-250A line array sub-bass system in a standard configuration. Each enclosure is equipped with rigging system, allowing flown array to be constructed rapidly and safely. W-210A is very versatile and scalable for a wide range of applications in touring performance, corporate and fixed installation fields. W-250A is dedicated high performance sub-bass system designed to augment the low frequency output of the W-210A, W-250A is a sub-bass enclosure which must be flown with W-210A. So its physical dimensions are identical to the W-210A and it is equipped with the same proprietary rigging system. It features with twin 15¡± neodymium woofers with magnet structure and suspensions engineered for maximum linear excursion Model W-210A/W-250A Type Line array system Line array sub-bass system(W-250A) Frequency Response 55Hz-20KHz 3dB 40Hz-150Hz 3dB(W-250A) Directivity index(Dl) 12(¡À2)1.2KHz-16KHz Power handing LF 500W(RMS)1000W(PEAK) HF 160W(RMS)320W(PEAK) 1200W(RMS)2400W(PEAK)(W-250A) Sensitivity LF 99dB(1W@1M) HF 108dB(1W@1M) 112dB(1W@1M)(W-250A) MaxS.P.L LF 127dB(PEAK/1M) HF 127dB(PEAK/1M) 143dB(PEAK/1M)(W-250A) LF section 2¡Á10"(260mm) neodymium woofer 75mm(3in)coil Components 2¡Á15"(380mm) neodymium woofers 100mm(4in)coil(W-250A) Nominal impedance 16 ohm 4 ohm(W-250A) HF section 2¡Á2"neodymium compression driver with 51mm titanium diaphragm Nominal impedance 16 ohm Output section 2-channel Dispersion pattern 110¡ãH¡Á9¡ãV Finish Water-proof,wear-resistant textured black paint Array design Arrays of less than 3¡ÁW-210A will provide poor dispersion control and are neither recommended nor supported Speaker cables LF 1(+)1(-) HF 2(+)2(-) 1(+)1(-) (W-250A) Rigging system Please refer to the W-210A user manual before any operation Input connectors 2¡ÁNL4MP speakon Recommend crossover LF 45Hz-1200Hz HF 1200Hz-20KHz 35Hz-120Hz(W-250A).
