As a full-featured digital mixer, the D-901 incorporates several useful built-in functions to ensure maximum performance without the need for other equipment. A compressor can be switched in to reduce the dynamic range between the smallest and largest signals, preventing amplifier clipping at high levels. The flexible crossover function allows setting speaker crossover points and filter slopes to optimize multi-channel speaker systems. Full equalization and filter setting configurations can be saved in up to 16 memories for instant recall. The time delay function can be used to align remote speakers.
Convenient front panel controls and display make it easy to perform all functions and confirm parameter settings without requiring a PC. Another advantage is the ability to store up to 16 sound parameter setting configurations in memory for instant recall when required. These include crossover, EQ, filter slope settings, time delay and other parameters. Control settings can also be locked to prevent unauthorized tampering. The D-901 can be externally controlled with an external signal trigger or the RS-232C port on the back panel which enables the D-901 to easily interface with external equipment.
