Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, a power amplifier rear panel of the present invention includes a panel main body (1) and a mounting part (2) fixed around the outer periphery of the panel main body (1), and is characterized in that the panel main body (1) is There are wireless microphone receiving area (3), signal input control area (4) and input power control area (5) successively from bottom to bottom.

[0021] The wireless microphone receiving area (3) includes two wireless microphone receivers (3.1) arranged horizontally side by side and antennas (3.2) respectively corresponding to the wireless microphone receivers. The wireless microphone receiver is a commonly used wireless microphone receiving device on the market. Of course, the wireless microphone receiver must include certain panels and buttons, which are conventional technologies a...

Abstract

The invention discloses an amplifier back panel, which comprises a panel main body (1) and an installing part (2) fixed on the outer periphery of the panel body (1) in a surrounding way. The amplifier back panel is characterized in that the panel main body (1) is provided with a wireless microphone receiving area (3), a signal input control area (4) consisting of a Bluetooth interface (4.1.1), an SD (Secure Digital) interface (4.1.2), a USB (Universal Serial Bus) interface (4.1.4), a 3.5mm socket (4.2.1) and an RCA socket (4.2.2) and a multifunctional socket (4.3.1), and an input power supply control area (5) in sequence from top to bottom. By adopting the structure of the amplifier back panel, a plurality of sound source input ways can be realized, and high universality is achieved; moreover, a plurality of amplifiers can be used together through an arranged signal output interface, so that the length of a connecting circuit is reduced. Moreover, a storage battery is provided, so that work without an external power supply can be realized.

Description

technical field [0001] The invention relates to the technical field of sound box equipment, in particular to a rear panel of a power amplifier. Background technique [0002] In this field, the power amplifier is also called "amplifier", and its function is to amplify the weak signal from the sound source or the pre-amplifier, so as to push the sound box to play. According to its use, it can be roughly divided into professional power amplifier, civilian power amplifier and special power amplifier. The professional power amplifier is mostly used in conference rooms, performance stages, halls, auditoriums and various venues, the civilian power amplifier is used in TV, home theater and various home multimedia equipment, and the special power amplifier is mostly used in various alarms and car Audio. It is not difficult to see from this that our life is full of all kinds of power amplifier equipment, providing us with a rich sound world. But at the same time, there are various ...
