Wireless Microphone System

 Solution Description

 

DSPPA new wireless conference room microphone system provides a new energy-saving mode, with automatic EQ control, tone correction and IR frequency synchronization functions. It uses the unique audio compressor design to effectively eliminate howling and completely eliminate interference signals to ensure that the system has a strong anti-interference function.

Therefore, with high flexibility and reliability, our UHF wireless conference microphone system is easy to operate and has compact structure, and the wireless microphone for conference room can be perfectly integrated into existing conference rooms without additional wiring, which is an ideal choice for mobile conference systems.

 

Solution Design

 

Usually, in a small closed indoor environment, it is not always the best to install more speakers. Generally, speakers are placed in pairs, mainly for symmetry, and reflecting the left and right channels for uniform sound field and appropriate loudness.

1. Audio source devices

Adopt a wireless microphone system (D5814/D5817) for conferences and speeches.

2. Audio processors

Adopt a mixer (MG12) to modify the audio source, and a feedback suppressor D6573, a digital processor D6575 and other devices to enhance on-site sound effects.

3. Speakers and amplifiers

Adopt two 250W full-range wall mount speakers (D6564), which uses a 10" woofer and a 1" tweeter to ensure sound effects, and a dual-channel 2*400 professional amplifier (MX2500II) to amplifier the power.

 

System Features

 

1. The human voice can be better reflected in meetings and academic reports, with clear sound and uniform sound field.

2. The infrared conference microphone has high flexibility and reliability, and uses a new type of anti-howling unidirectional high-sensitivity pickup microphone for perfect sound.

3. It can realize sound signal transmission with high fidelity, high SNR, strong anti-interference, no sound delay, etc.

4. The audio processors can make the speakers provide stable, clear and professional conference sound reinforcement effects.

5. The system can be used to various meeting forms such as conferences, speech reports, etc.

6. Easy to operate, the user can speak when he turns on the microphone switch, with compact structure, simple wiring, economical and affordable.

 

Series Products

 

The new generation of UHF conference room speaker and microphone system is composed of microphones and receivers. Among them, the microphones include handheld, clip, headset, and desktop microphones, while the receivers have two channels, four channels and eight channels. It can realize frequency synchronization between any receiver and any microphone in the system, providing customers with a variety of combination options.

Multimedia Amplifier for Mosques-MA2250U

 DSPPA microphone system for mosque

 

Amplifier Sound System Introduction

 

The Mosque can accommodate very large number of prayers and usually everyone prefers to pray in the mosque. The Holy Qaran which is recited at the mosque is heard by all the people who are living in the same community. Hence, it’s important to have a better mosque sound system that can produce a pleasant audio quality.

DSPPA MA2250U is specially designed for mosques - the perfect choice for every small and medium-sized mosque sound system. It has two built-in 250W amplifiers and a mixer with digital sound processor, as well as a built-in effector. Besides, it has multi-channel MIC inputs with reverberation effect, and it can be externally connected to Azan audio, with MP3/Bluetooth and other audio sources optional. The amplifier has two channels of constant-voltage and constant-resistance outputs, with independent volume adjustment for each channel. Therefore, it is an integrated system that can best meet your various requirements.

 

Amplifier Features

 

Compact All-in-one Device Digital Mixer Amplifier

MA2250U is a 2-channel multimedia mixer amplifier for mosques, with RMS power of 2*250W. Support separate control of Echo/Bass/Treble/Volume for 2-channel ouputs,  with built-in 3 MIC, 1 AUX and USB/Bluetooth. MA2250U is the perfect choice for your mosque.

 

Better than other masjid speaker system:

Generally, the masjid sound system consists of sound amplifiers, horn speakers, ceiling speakers, sound mixers and microphones. Since the quality of these equipment varies from brand to brand, the price of the sound system is based on the quality, and the complicated sound system setup and different microphones will cause more sound quality problems, DSPPA has designed an integrated power amplifier MA2250U specially for small and medium-sized houses of worship.

 

The voice of Imam should be sent to every worshipper in the mosque, and must be clearly heard in the farthest corners. Therefore, microphones and speakers should be carefully selected and installed according to the architectural and acoustic characteristics of the mosque.

However, most of mosques are rarely considered from the acoustic aspect, so the echo, longer reverberations of sound and feedback will affect the intelligibility of Azan and Khutba.
