MC7540 Digital Amplifier 350W
- Product Description
Using self-developed super-capacity switching power supply digital power amplifier. Compared with open-loop or semi-closed-loop control methods, compound feedback control can greatly reduce the influence of power fluctuations, switching devices and LC filter errors and non-idealization, so that key technical indicators such as distortion, frequency response, and damping coefficient can be greatly improved. The amplitude is improved and the hearing performance is perfect. The switching power supply is optimized and designed according to the working characteristics of the audio amplifier, with strong power, quick response and little interference to audio signals. In addition to multiple protection circuits such as short-circuit, over-current, over-temperature, and ultra-high frequency, it also pays attention to humanized design to facilitate operation and prevent possible misoperation. 1U height 19-inch standard rack size, small size, light weight, suitable for mobile and fixed installation. There are two working modes: STEREO (A and B, C and D work independently in this mode), PARALLEL (In this mode, the device outputs a mono channel signal source through a dual amplifier system).SpecificationsOutput: 4x300WFrequency response: 20Hz~20kHz ±3dBTotal distortion: 1% (at 8Ω, 350W)Input sensitivity: +4dB * (1.23V)Input impedance: 10kΩ (electronically balanced)Signal to noise ratio: ≥80dBSize: 483x45x500(mm)Net weight: 5.40kgMC7540 four-channel digital power amplifier size chartMC7540 four-channel digital power amplifier panel function display diagramKeywords:
