The Atlas HPA-DAC4 accessory card is designed to work in conjunction with HPA Series 4-channel amplifiers. The HPA-DAC4 is a 4-input Dante receiver that features digital audio transportation over standard IP networks. The HPA Series 4-channel amplifiers come standard with four balanced line inputs and an accessory card slot to add an additional 4-inputs, giving the amplifier a total of 8-inputs.
Analog Input 1 and Dante Input 1 are isolated from each other and are electronically summed together forming a mixed output. Both Input levels to the amplifier channel are controlled by the Ch-1 level control. Channel 2, 3, and 4 inputs are configured the same as Channel 1.
