AD8HR is an 8-channel AD converter with remote microphone preamplifier, which has 96kHz, 24-bit linear AD converter, 128 times oversampling and 110dB dynamic range. Its input part has balanced XLR interface, high quality microphone preamplifier and +48V phantom power supply function, and simultaneously supports microphone and line level input. The output part supports AES/EBU format, and has 88.2/96kHz high sampling frequency. It is easy to adjust the gain of each channel (in 1dB steps) and set the high pass filter from the front panel. These settings are stored in the device's backup storage and will be retained even when the power is turned off. In addition, there is a special protocol that allows you to remotely control the device from a connected computer or other device.
The Yamaha AD8HR is a professional audio interface designed for use with Yamaha mixing consoles such as the PM5D and DM2000. It provides eight channels of high-quality analog input and output, supporting sampling rates up to 96kHz.
The manual details how to connect the unit using XLR inputs/outputs, word clock, AES/EBU digital audio, and remote control interfaces. It also explains the operation of various controls including gain, phantom power (+48V), high-pass filters (HPF), pad settings, and LED indicators.
