Owner’s Manual Thank you for choosing the Yamaha AD8HR AD converter with remote microphone preamp. 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 line- level inputs.

DM2000 to control the AD8HR remotely. In a multiple AD8HR system, connect an AD8HR to [HA REMOTE] connector 1 on an additional AD8HR. NOTE: Please visit the following Yamaha website for the latest information about the devices that can control the AD8HR remotely. http://www.yamahaproaudio.com/...
Basic Operations Selecting the Wordclock You can select from the following wordclock source options: internal clock (44.1kHz, 48kHz, 88.2kHz, and 96kHz), WORD CLOCK IN, or DIGITAL OUT A. Press the [WORD CLOCK] button repeatedly to select the wordclock source. The indicator of the selected wordclock ﬂashes rapidly. While the indicator is ﬂashing rapidly, press the [WORD CLOCK] button again.
Basic Operations Setting the High Pass Filter Each channel features a high pass ﬁlter (12dB/octave) that you can turn on or off. You can set individual cut- off frequencies for each channel’s high pass ﬁlter. Press the Channel Select button to select a channel.
Remote Control A special protocol enables you to control the AD8HR from a computer or Yamaha PM5D or DM2000 that is connected to [HA REMOTE] connector 1. You can also remotely control up to 255 AD8HRs that are connected to one another.
Use a D-sub 25-pin AES/EBU cable to connect a digital audio device that supports the AES/EBU format. To connect a Yamaha PM5D or DM2000 to the AD8HR, ﬁrst you must install an optional I/O card (MY8-AE, MY8-AE96S, MY8-AE96, or MY16-AE) in the PM5D or DM2000.
Wordclocks For proper AD conversion and digital audio data transmission and reception, the D8HRs and external digital audio devices must lock to an identical wordclock. The AD8HR is capable of transmitting a wordclock signal of 44.1kHz, 48kHz, 88.2kHz, and 96kHz, you can use the AD8HR as the wordclock master and the external devices as wordclock slaves.

The AD8HR automatically diagnoses itself at the time of power up. If it detects a system abnormality, one of the following error messages appears. If an abnormality is detected, consult your Yamaha dealer. The backup battery voltage is low. If the voltage is lowered further, the stored data will be erased. Ask your dealer to replace the battery.
