Our sincere attitude to meet your inquiry: Company name: Beijing Venture Technology Co., Ltd. Hengxing Mobile: 15811405546 Business QQ: 420540227 Contact: Lee power timing devices power supply timing device in accordance with the previous stage to a subsequent device individually in order to start the power, by order level to the previous level after the closure of all types of electrical equipment closed power supply, so that we can effectively manage and control all kinds of unified electrical equipment, avoiding human errors operation, while at the same reducing electrical equipment in the switching instant impact on the power supply network, but also to avoid the induced current impact on the device to ensure the stability of the entire electricity system. Wireless handheld microphone wireless handheld microphone, if cadres by pocket transmitter (can be installed in his pocket, the output power is about 0.01W) and a centralized receiver, pocket transmitter each have a portion of mutually different frequency, focus receiver can simultaneously receive different ministries issued pocket transmitter operating frequency voice signal. It was adapted to the stage podium occasions. Wireless lapel microphone wireless lapel microphone is a wireless microphones, are generally capacitively microphone. Suitable for large-scale flow of the meeting, recording, public communication, outdoor speeches, give lectures and other occasions. EQ EQ is the acoustic signal frequency and amplitude adjusted in response to the reaction of electro-acoustic processing equipment. It can change the composition ratio of sound and harmonics, frequency response curve, the band width. Frequency equalizer wide variety of audio systems, such as Hall PA system playback, radio recording systems and home audio systems. In the recording (refer to the same period of the pre-recording and multi-track recording) and post-processing (ie ready-made recording the second time balancing and multi-track recording program post-production) and to beautify the sound to play a broader role. For example: (a) to make up for frequency response deficiencies; (b) make up the sound source sound quality defects; (c) to highlight the characteristics or change the instrument sounds of musical instruments; loudness (d) the balance of each part of the band; (e) enhance the music signal fullness, brightness and clarity; (f) increased presence, adjust performance level; (g) relieve the part between crosstalk attenuation frequency leak; (h) removing noise and interference sound, noise ratio; (I ) Fixed frequency response deficiencies listening environment, balanced indoor response - can be said equalizer sound engineer and sound engineer is the most important work of the tuning tool. The most important tool is our voice workers to improve voice tone. Our sincere attitude to meet your inquiry: Company name: Beijing Venture Technology Co., Ltd.
