Description

Technical Field

[0001] This utility model relates to the field of mixing console technology, and in particular to a mixing console with selectable input channels. Background Technology

[0002] A mixing console, also known as a sound mixing control unit, amplifies, mixes, distributes, modifies the sound quality, and processes the audio effects of multiple input signals before outputting them through a bus. Mixing consoles are essential equipment for broadcasting and recording programs in modern radio broadcasting, stage sound reinforcement, and audio program production systems.

[0003] A search revealed that Chinese utility model patent CN202221636056.2 discloses a digital mixing console device, relating to the field of music equipment technology. It includes a mixing console body, a lower protective plate, and a U-shaped clip. A first rubber pad is attached to the inner side of the lower protective plate and is connected to the mixing console body via the first rubber pad. A first damping shaft is installed at one end of the lower protective plate. This digital mixing console device, through the lower protective plate, connecting plate, and upper protective plate, encloses the outside of the mixing console. With the rubber pad, it provides good impact resistance, vibration damping, and dust protection, thus preventing damage from falling debris. Simultaneously, the connecting plate and upper protective plate can switch between different configurations via the damping shaft. On one hand, it can support the mixing console, eliminating the need for a separate support; on the other hand, the angle can be adjusted according to the user's needs, facilitating outdoor operation and improving the user experience.

[0004] For example, Chinese utility model patent application number CN202420122456.4 discloses a novel noise reduction circuit for a mixing console, including a tuning button circuit, a main control circuit, a left tuning output circuit, a right tuning output circuit, a power supply circuit, a left noise reduction circuit, and a right noise reduction circuit. The main control circuit is electrically connected to the tuning button circuit, the power supply circuit, the left tuning output circuit, and the right tuning output circuit, respectively. The left tuning output circuit and the right tuning output circuit are electrically connected to the left noise reduction circuit and the right noise reduction circuit, respectively. This utility model reduces noise by adding left and right noise reduction circuits to the left and right channel audio signals output by the left and right tuning output circuits, respectively. This greatly reduces noise without affecting the audio output effect, and it requires no additional wiring, resulting in lower cost and greater convenience of use.

[0005] While the existing mixing consoles can meet basic usage needs, their channel input channels are relatively limited, offering either 8, 12, or 16 channels. They cannot select input channels according to the user's mixing requirements, resulting in low intelligence and a poor user experience. Utility Model Content
