PMM88A

★ Set gain, noise gate, matrix, automatic mixing, feedback suppression, equalization, pressure limit and delay

★ All inputs have MLS technology to support all kinds of microphones signal input and music signal input, each input setting can be manually adjusted by software or panel LCD display menu

★ With AEC adaptive acoustic echo elimination function, level 6 tail L effect adjustment, it is suitable for various interactive recording and broadcast teleconference, teaching application occasions, to restore clearer voice communication

★ All microphones input with 9 level sensitivity adjustment 0-35dB gain, and with 48V phantom power switch, can match different sensitivity of all kinds of microphones;

★ Built-in white noise, pink noise, sine wave three different test signal sound sources, can be used as a variety of systems to detect sound sources;

★ All input bands have AFC technology active feedback inhibition function, two-gear adjustment

★ With AUTOMIX shared gain type automatic mixer, each channel is independently adjusted, with 10 level priority gear, can adjust the slope and response time, between the microphones, microphones and music signal, automatic switching, music signal can also reduce noise, H signal-to-noise ratio, reduce the noise phenomenon;

★ Built-in powerful matrix mixing function, full open architecture, free Settings, each mixing can also independently adjust the mixing volume, matching gain is more convenient, intuitive view and debugging signal routing situation;

★ All input 31 segment PEQ, all output 10 segment PEQ adjustable, with H low frame and all-pass filter, input and output with 48 order H low-pass frequency distributor. The adjusted parameters can be saved and copied to other channels independently, convenient for comprehensive adjustment of the sound system

★ With video tracking control function, RS232 / 485 interface, support camera control PELCO-D / PELCO-P / VICA and other protocols

★ Standard USB (TYPE-B) port, three functions: support drive-free automatic connection software debugging; built-in U disk function, storage software and instructions; with USB sound card.

★ Support for mobiles phones APP TCON software network control

★ Support archiving and locking to avoid misoperation or artificial disturbance of processor parameters to maintain system stability; archiving can automatically save all instant debugging parameters, or set unique startup state parameters to meet different system maintenance requirements.

★ Supports the unified management of GPIO general control interface Mconsole software platform, can connect control equipment through USB / RS232 / RS485 / multiple interface TCP / IP, TCP / IP control port can also realize LAN remote and multiple equipment control, multiple equipment synchronization parameters, joint parameters and other powerful functions

★ Support central control command, the software can realize central control function through RS232 / RS485 / TCP / IP
