Delors D-MX432 four smart meeting mixer

Product Description D-MX432 four smart meeting mixer: Product Description: D-MX432 four-channel smart meeting mixer: the 4-way signal input, automatically turn on only the signal input channel, the channel gate operation level can be automatically adjusted or manual adjustment. NOMA function according to the increased use of the channel, automatically adjust the output level to effectively prevent occurrence of howling. Each channel can be individually set as a priority speech mode and loaded limiter. At the same time via RS-232C port communication, use a small controller computer, in control or the machine configured for remote control of the microphone switch for easy cutting unnecessary microphone input mixer supports multiple extensions, expandable up to 32, the rear panel with external control output terminal, the camera can be configured based on the composition of videoconferencing system control protocol. Features: 1: with 4-way signal input, automatically turn on only the signal input channel. Channel gate operation level can be automatically adjusted or manually. 2: Each channel can be set as a priority to speak, in his speech the priority channel, speaking of the other channels will automatically shut down. 3: inputs for each channel can be depending on the input device, select a different input levels, and you can also adjust individual channel gain. 4: The volume can be adjusted individually for each channel, the other comes with a high-performance low-frequency attenuation circuit 75Hz, effectively cut the low-frequency signal interference. 5: a 48V phantom power selector switch, sub-CH1-2, CH3-4 groups. To meet the needs of many types of microphones and audio equipment inputs. 6: NOMA function: NOMA (Number of open Microphone Atte nuated) lines can be increased based on the use of channels, automatically adjusts the output level. When using multiple mixers extend to prevent the rise due to the overall gain of the system, and produce sound whistle. 7: with Aux & Control interface, control external lights or camera control unit. 8: equipped with RS-232 interface to connect the control and the external controller, convenient control channel is turned on or off, and has strong expansion capability. 9: external controller, internal mixer used without automatic control switch directly to force the microphone is turned on or off by an external controller, easy to cut unnecessary microphone input.
