Atlas IED DPA804 4-Channel Networkable Power Amplifier, 800W

Flexibility, performance, and control define the DPA804 amplifier from Atlas. A 4-channel amp that can be used right out of the box as a traditional four-channel 70.7V commercial power amplifier requiring no programming, special set-up, or network connectivity, the 804 can also be configured in four-channel mode with either 4Ω or 8Ω load impedances for two stereo zones. This allows the 804 to be configured as a 70.7V/100V paging/background system on two channels and the other two channels can be used for 4Ω/8Ω foreground stereo applications, offering you maximum flexibility.

The DPA804 comes standard with four balanced line inputs and an accessory slot for an optional DPA-DAC4 four-channel Dante™ receiver card or a DPA-AMIX (2) mic/line and (2) AUX input card (all sold separately), for a total of eight inputs. The inputs can be mixed and routed to any of the four output channels and processed with an assortment of DSP tools, including level controls, EQs, limiters, high & low pass filters, and delay to suit the application.

Output levels can be controlled from the front panel knobs, the user interface, or wired remote control. The user interface also features input and output level metering along with assignable mute functions that are triggered via an audio signal or contact closure. Access to the DSP settings is accomplished via computer, tablet, or mobile device using a web browser, and all settings can be password protected.
