The 2 RU, four channel 10D amplifier is designed for permanent integration with applications that require lower Sound Pressure Level (SPL) capabilities. This device contains extended input management functionalities with separate Input Gain control for each input channel, General Purpose Inputs/Outputs (GPIO) and a General Fault connector. Enhanced system status monitoring functions such as Input and Load monitoring ensure suitability in an emergency situation. The 10D shares the same Digital Signal Processing platform as the latest generation of four channel d&b amplifiers, providing configurations for smaller d&b loudspeakers as well as a linear mode.
