Technical features of HIFI Commercial Power Amplifier

Image
HIFI amplifier is slightly different from AV amplifier, and HIFI amplifier often has the following characteristics 1. 2.0 channel stereo. There is only two channels output for most of the HIFI amplifier. Unlike the surround effect of AV amplifier, HIFI amplifier pay more attention to high fidelity sound quality, much lower distortion and real music restoration. 2. By the front and backstage separation, the advanced HIFI   commercial power amplifier   can ensure much higher quality sound reproduction. 3. The high dynamic amplifier module (HDAM) in HIFI amplifier can help produce more dynamic, accurate and sophisticated sound. 4. A high-quality HIFI amplifier must be equipped with a stable mechanism and a thick metal panel to reduce the interference between the audio circuits, which is helpful for the improvement of sound quality. 5. The current feedback type high-speed discrete circuit is adapted to realize the high channel separation degree of the super high field. ...

Hybrid Phonograph Preamplifier Nagra VPS

Image
Feature 1: different equalization methods are realized by jumper Nagra VPS provides two equalization methods: RIAA 1953 and IEC 1976. The jumper is set through the first level of each channel. If the jumper is connected, RIAA 1953 equalization method is produced with maximum bandwidth. If the jumper is removed, IEC 1976 equalization method is produced in which frequency 90Hz below will show attenuation trend. At this point, the rumbling noise from some photographs is inhibited and eliminated because that frequency below 50Hz is removed. So, the users can listen without any interference. Feature 2: the input transformer for moving coil cartridge plays a significant role When Nagra VPS runs input signal of MC moving-coil cartridge, it's high fidelity of the output signal benefits from high efficiency of the input transformer. Besides high efficiency, there are other advantages as following for the glass-core transformer which has magnetic head similar to that of tape recorder. Firstl...

Television Signal Multi Zone Mixer

Image
Television signal mixer is a device that combines more than two sets of radio-frequency signals with different frequencies together to form one-way broadband radio-frequency signal and output multi-channel program. The television signal mixer is a special mix-frequency device designed for the adjacent frequency front end system of cable television multi-channel. Technology features of television   Multi Zone Mixer   the circuit structure of the television signal mixer is used with transmission transformer coupling type and used for 1000 MHz adjacent frequency broadband transmission system. The key magnetic material is imported, the harmonic output is low, the reflection loss is big, the standing wave is small, the isolated degree with each other is high, the insertion loss is small, the input frequency band is wide. 16-way signal is input and then mixed into 1-way signal and output. 1-way signal monitoring and each way index is same. The input channel with good interchangeabil...
