Functional & Interface Accessories
The amplifier shall be EN54-16 complied digital power amplifier without output transformer. It shall be a 2U rack-mount unit equipped with 4 channels of class-D digital power amplifiers, which contribute to energy-saving and lightweight design. It shall include independent power supply for each channel. If the power supply of Channel 1 should fail, this shall not affect the operation of Channels 2-4. The amplifier shall incorporate 4 BGM inputs. The BGM can be broadcast to local area (limited area) as well as the audio inputs of the whole system. BGM volume shall be adjustable on the rear panel of amplifier. Change to standby mode from external input shall reduce standby power consumption. Removable terminal block shall allow easy connection.
LED indicators of each channel shall make it possible to easily recognize the unit operating condition and audio input signal. The amplifier shall operate on 31V DC supplied from the dedicated Power Supply Unit.
