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. [. . . ] While the indicator is flashing rapidly, press the [WORD CLOCK] button again. The AD8HR switches to the selected wordclock source and the flashing wordclock indicator stays lit. The indicator of the previously-selected wordclock source turns off. If you do not press the [WORD CLOCK] button again before the indicator stops flashing (it will flash for five seconds), the new selection is cancelled and the previous wordclock is selected. If the AD8HR is not locking to the selected wordclock source, the corresponding wordclock source indicator flashes. NOTE: The only word clock source available via the AES/EBU connection is the IN signal of DIGITAL OUT A channels 1/ 2. While the indicator is flashing rapidly, press the [+48V] button again.

NOTE: · While adjusting the gain, you may notice that the sound is briefly interrupted. The internal setting is switched in steps of 6 dB, and the sound is momentarily muted so that the noise will not be created during the switching operation. · The PAD will be switched on or off internally when the gain is adjusted between -14 dB and -13 dB. Keep in mind that noise may be generated if there is a difference between the Hot and Cold output impedance of the external device connected to the INPUT connector when using phantom power. Setting the Phantom Power Follow the steps below to turn the +48V phantom power for each channel on or off. NOTE: You can also turn the phantom power for all channels on or off simultaneously (not individual channels) using the [+48V MASTER] switch. When the [+48V MASTER] switch is turned off, the phantom power is not supplied to channels even if the [+48V] button is turned on for the channels. Adjusting the Gain Trim (Gain Correction) Follow the steps below to correct the channel gain in 0. 1dB steps. The output level of each channel has been calibrated in the factory. Typically, you will not have to correct the setting. NOTE: In the factory, the level has been set to the optimum value and the initial level varies with each channel. This setting is reset to the factory value when you initialize the backup memory. 1 Press the Channel Select buttons to select the channels.
