Description

Details

The Atlas Sound DSP2210 is capable of automatic mixing, set up and administration of all inputs/outputs per zone (channel). This is accomplished via an intuitive ‘simple to use' Graphic User Interface (GUI) managed via a local laptop or desktop computer that is running Microsoft Windows. It provides up to 2 channels of independent on-board digital Class-D amplifiers rated at 25W RMS at 70V. It has a pink noise generator which is random and non-repeating up to (215) hours with EQ adjustments programmable on a per zone basis.

The DSP's provide dynamic control and management with independent 1⁄3 Octave (28) band EQ (Filter type is Butterworth @ 19dB and Linkwitz-Riley at 24dB) and Parametric EQ 8-band for calibration of all PA and masking signals on a per zone basis. Paging (PA) levels are adjustable in 0.5dB increments per zone on Line Level (Music) and Microphone paging inputs.
