A multi-zone pa amplifier is a professional tool for commercial use with sophisticated industrial design and construction. The volume and weight are greatly reduced by the official DriveCore technology - all mixer/ammeter are efficient, without a fan, only 1U rack space is large. Single channel and dual channel model is equipped respectively with four or eight mixer TV channels. There are unique and easy functions and features for CSMA mixer/ammeter: only volume control for each channel, easy to clean, master volume adjustment on the front panel, adjustable bass and treble and the power switch. All controllers of the volume are surrounded by bright rings that make it easy for them to see and operate in a dark environment. The   multi-zone pa amplifier  can drive 8 ohms and 4-ohm loads and it can use the 70V and 100V distributed audio systems without separate transformers. In addition to the balanced microphone/line input, unbalanced RCA input, and speaker connection, all units...

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 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...

The pre AMP amplifier is circuit or electronic device placed between signal source and amplifier. It is designed to receive the weak voltage signal from the signal source. The preamplifier amplifies the useful signal as well as the noise. The low-noise preamplifier is preamplifier that minimizes the noise factor of the circuit. For weak signal detection instruments or devices,   pre AMP amplifier   is one of the main components to introduce noise. The noise factor of whole detection system mainly depends on the noise factor of   pre-AMP amplifier . The minimum signal that instrument can detect also depends on the noise of preamplifier. Pre-AMP amplifier is usually connected directly to the sensor used to detect signal. Only when the best source resistance is equal to the signal source output resistance, noise factor of the circuit will be minimized.   The function of the   Pre AMP Amplifier 1. Improve SNR of the system (improves the SNR because preamplifier c...

The channel multi zone mixer is a command about color adjustment in the Adobe photoshop software. This command can adjust the color composition of a certain channel. Execute "Image - > Adjust - > Channel mixer [1]" command, and pop-up "Channel mixer" dialog. Output channel: it refers to the channel in which you can choose to mix one or more source channels. The source channels: drag the slider to reduce or increase the percentage about source channel in the output channel; or enter directly values between -200 ~ +200 in the text box. Constant: it refers to the item which you can add an opaque channel to the output channel. If it is a negative value, it is black channel. Monochrome: check this item to apply the same settings to all output channels and to create a grayscale image in this color mode. The working principle of channel Channel   Multi Zone Mixer amplifier   Select a certain channel in the images as the processing target (that is, the output channel)...

Whether you are operating performance area or building a mobile platform, you always need an excellent PA system which not only can meet your requirements at present, but also can meet your requirements in the next few years. We can divide the PA system into three large types: personal PA, medium PA and full-size PA. Personal PA usually consists of a single speaker or mini-speaker array (such as the Bose L1 series), which can be used either as the primary speaker of a player or as feedback sound device. The medium PA usually consists of a pair of vertical speakers on either side of the stage and a simple wedge-shaped feedback sound device. The PA system which is used in large stadiums will use speaker linear array and extremely complex feedback sound system. We can see the medium   professional pa amplifier   system in most of nightclubs, churches and mobile DJ platforms. If there is small-scale audience, you should use the suitable medium PA power amplifier. However, if t...

In general, compared with the frequency division box, ordinary inverted phase full frequency box, TQWT full frequency box, large baffle and other sound boxes, it is worthwhile to use a sound box with full frequency and horn to listen to music. Although the full frequency horn sound box is a bit heavy, it is common that a big horn has weight of dozens of or hundreds of kilograms. The waterproof horn speaker is a kind of high quality replay boxes. Although the sound distortion and box sounds of baffle are smaller, if you want to achieve the same low frequency submergence and sense of quantity as the full frequency horn, the size of the baffle should be extremely large, and the demand for the loudspeakers should be relatively higher, thus, in fact, the cost will be more higher. Therefore, the full frequency horn is worth playing, it can bring good sense of hearing, its sound quality will not let you down as long as you debug it well! It is suitable to use the tube...
