- Description
Details
The DSP8807 has 8 channels of independent on-board digital class-D amplifiers that are capable of delivering 50W RMS at 70.7V output. Additionally a simultaneous audio line level output rated at 1V/600Ω (nominal) per zone is available for driving higher power amplifiers. The DSP8807 also has two independent uncorrelated pink noise generators which are random and non-repeating up to 215 hours with EQ adjustments programmable on a per zone basis.
The DSP8807 provides dynamic control and management based on IEEE802.1 AVB standards (Audio-Video Bridging) with independent 1⁄3 Octave (28) band EQ *(Filter type is Butterworth at 19dB and Linkwitz-Riley at 24dB) and Parametric EQ for calibration of all PA, ambient level sensing and automatic level control on a per zone basis. The volume control for paging in each zone can be individually controlled in 1dB increments from 15dB to -65dB.
The DSP8807 GUI is called the ‘Sound Media Interface'. The software has the ability to expand up to (253) systems with over 2,000 zones (2,048) with primary and secondary assignment in a zone paging dialing plan. It also provides the ability to set up "All zone" page, "Group zone" page (up to 32 groups) and "Single zone" page with an architectural dialing plan (2-digit DTMF) set up in the GUI. Each DSP8807 is capable of managing remote ambient level sensing microphones (ALM-1) for each zone (x8) wired via a single CAT5e cable up to 1,000 feet from the DSP8807 for automatic adjustment of the masking level based on real time noise levels with set up and control via the GUI.
