The AD8HR is an eight-channel AD converter equipped with remote microphone preamps that feature 96kHz, 24-bit linear AD conversion, 128-times oversampling and a dynamic range of 110dB. Its input section features balanced XLR connectors, high-quality mic preamps, +48V phantom power, and support for both mic and linelevel inputs. The output section supports the AES/EBU format and features a high sampling frequency of 88.2/96kHz. You can easily adjust the gain for each channel (in 1dB steps) and set up the high pass filter from the front panel. These settings are stored in the unit’s backup memory, and are retained even after the power is turned off. In addition, a special protocol enables you to remotely control the unit from a connected computer or other device.
