The SQ-ADA-1002 is an analog audio dual 1×4 distribution amplifier (DA) which is used in SEQUOIA Series Signal Processing Platform. It provides dual-channel DA with four analog audio outputs for one analog audio input on each channel. The SQ-ADA-1002 supports by-pass protection for the first output on each channel. Thus the signal can be output continuously when the module is removed or the power is off. LED indicator on module edge shows the status information of signals, and the ADJ switch can adjust the parameters manually. Module with independent rear panel can be used in SEQUOIA 1RU or 2RU frame. The SQ-ADA-1002 supports the function of network monitoring of Sequoia series platform. The module can be controlled and monitored via SEQUOIA network control module and SQ-MASTER platform control software.
