Rear Panel 3 1 2 4 5 6 7 A Grounding screw For safety, use this screw to ground the AD8HR. The included power cable has a three-pin plug. If the AC outlet is grounded, the AD8HR will be grounded correctly via the power cable. If the AC outlet does not provide a suitable ground, this screw must be connected to a suitable ground point. Grounding is also an effective method for eliminating hum, interference, and other noise. B [AC IN] connector Connect the included power cable here. First, connect the power cable to the AD8HR, then insert the power cable plug into the AC outlet. WARNING Be sure to use the included power cable. Use of other cables may result in malfunction, heat generation, or fire. C [HA REMOTE] connector 1 This D-sub 9-pin connector is used to connect a computer or Yamaha PM5D Digital Console or 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/ 6 8 9 D [PC RS422] switch If you connect a computer to [HA REMOTE] connector 1, set this switch to PC. If you connect a Yamaha PM5D or DM2000, or an additional AD8HR in a multiple AD8HR system, to [HA REMOTE] connector 1, set this switch to RS422. E [HA REMOTE] connector 2 In a multiple AD8HR system, connect one AD8HR to this D-sub 9-pin connector on another AD8HR. F [DIGITAL OUT A/B] connector These D-sub 25-pin connectors output AES/EBU format digital audio. In Double Speed mode, each connector outputs digital audio data routed from Channels 1–8. In Double Channel mode, the [DIGITAL OUT A] connector outputs digital audio data routed from Channels 1–4, and the [DIGITAL OUT B] connector outputs digital audio data routed from Channels 5–8. G [WORD CLOCK OUT] connector This BNC connector outputs a wordclock signal. H [WORD CLOCK IN] connector This BNC connector inputs a wordclock signal. This connector is terminated at 75Ω. I INPUT 1–8 connectors These balanced XLR-3-31-type connectors are used to input analog signals to the corresponding channels.  Basic Operations Basic Operations Selecting the Wordclock 3 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. 1 2 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. 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. While the indicator is flashing rapidly, press the [+48V] button again. The phantom power for the selected channels turns on, and the corresponding channel [+48V] indicators and the [+48V] button indicator light up. If you do not press the [+48V] button again before the indicator stops flashing (it will flash for five seconds), the setting is cancelled. Adjusting the Gain Follow the steps below to adjust the channel gain in 1dB steps. 1 2 Press the Channel Select button to select a channel. The selected channel’s Channel Select button indicator lights up and the Gain display indicates the gain value. Rotate the Gain control to adjust the gain You can adjust the gain in the range of 10dB through –62dB in 1dB steps. NOTE: NOTE: • While adjusting the gain, you may notice that the sound is briefly interrupted. This is not a malfunction. 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 only word clock source available via the AES/EBU connection is the IN signal of DIGITAL OUT A channels 1/ 2. • 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. 1 2 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. Press the Channel Select buttons to select the channels. The selected channels’ Channel Select button indicators light up. The channel +48V indicator lights up when the +48V phantom power for the selected channels is turned on. Press the [+48V] button. If phantom power for the selected channels was off before the operation, the [+48V] button indicator starts flashing rapidly. If phantom power for the selected channels was on before the operation, the [+48V] button indicator and the phantom power for the selected channels turns off. 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 and hold down the desired Channel Select button for more than two seconds. The Channel Select button indicator flashes and the Gain display indicates the gain trim value. 7  Basic Operations 2 3 Rotate the Gain control to adjust the gain trim value. You can adjust the gain trim value in the range of –1.5dB through +1.5dB in 0.1dB steps. Press the same Channel Select button again. The Channel Select button indicator lights up and the Gain display indicates the gain value. Selecting the AES/EBU Format You can select Double Speed mode (AE1) or Double Channel mode (AE2) for the AES/EBU format. ■ Double Speed Mode In Double Speed mode, digital audio data is transmitted at the current higher sampling rate (i.e., 88.2kHz or 96kHz). Select this mode if the devices that support the higher sampling rates receive data. The [DIGITAL OUT A] and [DIGITAL OUT B] connectors each output digital audio data routed from Channels 1–8. 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 cutoff frequencies for each channel’s high pass filter. 1 2 3 4 5 Press the Channel Select button to select a channel. The selected channels’ Channel Select button indicators light up. The channel HPF indicator lights up when the high pass filter for the selected channels is turned on. To change the cut-off frequency, press and hold down the [HPF] button for more than two seconds. The [HPF] button indicator flashes rapidly and the Gain display indicates the cut-off frequency. Rotate the Gain control to set the cut-off frequency. You can set the cut-off frequency in the range of 20Hz through 600Hz (in 60 steps). Press the [HPF] button again. The [HPF] button indicator returns to the previous (on or off) status and the Gain display indicates the gain value. Follow the steps below to copy channel settings to another channel. You can copy the following settings: channel gain, high pass filter on/off, cut-off frequency, and phantom power on/off. The gain trim value will not be copied. 8 In Double Channel mode, digital audio data is transmitted as mono signals at a sampling rate that is exactly half (44.1/48kHz) the current higher sampling rate. The data is handled by two channels. This is useful when you wish to transfer data from the AD8HR running at a higher sampling rate to legacy 44.1/48kHz digital devices. The [DIGITAL OUT A] connector outputs digital audio data routed from Channels 1–4, and the [DIGITAL OUT B] connector outputs digital audio data routed from Channels 5–8. However, if the AD8HR is running at a sampling rate of 44.1/48kHz, each connector outputs digital audio data routed from Channels 1–8. If the wordclock master is DIGITAL OUT A, the AD8HR will run at a clock rate that is twice (88.2/ 96kHz) the incoming clock (44.1/48kHz). Press the [HPF] button to turn the channel high pass filter on or off. Copying the Channel Settings 1 ■ Double Channel Mode Press and hold down the Channel Select button of the copy source channel, and press the Channel Select button of the copy destination channel. The channel settings will be copied. To copy the same channel settings to a different channel, continue holding down the Channel Select button of the copy source channel, and press the Channel Select button of the target channel. 1 2 Turn off the power to the AD8HR. Press and hold down the [WORD CLOCK] button and the Channel Select button of Channel 1 or 2, then turn on the [POWER] switch. Pressing the Channel Select button of Channel 1 will select Double Speed mode (AE1). Pressing the Channel Select button of Channel 2 will select Double Channel mode (AE2). At the same time, the Gain display will indicate the selected mode (AE1 or AE2) for one second.  Basic Operations Adjusting the LED Brightness Follow the steps below to adjust the brightness of the front panel LED and Gain display. 1 While pressing and holding down the Channel Select button of Channel 8, rotate the Gain control to adjust the brightness. You can adjust the brightness in seven steps. Panel Operation Lock You can lock the buttons and controls on the front panel to avoid any trouble due to unauthorized or unintentional operation. Note that you cannot lock the operation from the remote control. 1 Press the [WORD CLOCK] button, [+48V] button, and [HPF] button simultaneously. This will turn the Panel Operation Lock function on or off. If the Panel Operation Lock function is turned on, the Gain display flashes when you operate the front panel, but you cannot change the settings. Initializing the Memory Follow the steps below to initialize the backup memory to reset to the factory value. 1 2 Turn off the power to the AD8HR. While pressing and holding down the Channel Select button of Channel 4 and the [+48V] button, turn on the [POWER] switch. The backup memory will be initialized. The backup memory stores the following settings. Channel settings • • • • • Phantom power on/off Gain Gain trim High pass filter on/off High pass filter cut-off frequency Global settings • • • • Wordclock AES/EBU format LED brightness Panel Operation Lock setting 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. However, the maximum number of AD8HRs that can be controlled remotely depends on the type of connected device. When each AD8HR receives control signals, the Gain display indicates the ID number of the corresponding unit. This is useful when you wish to identify each of multiple AD8HRs that are connected in a system. When you operate the panel on the unit, its ID number on the Gain display disappears. The ID number of the AD8HRs is determined based on the connection order in the daisy chain. You can also create a daisy chain connection that mixes AD8HRs and Yamaha AD824 AD converters. However, in such a system, any AD8HR that is connected after any AD824 unit (when seen from the host device; e.g., computer) will be recognized as an AD824, and you will be unable to control the following functionality on these AD8HR units. For this reason, we recommend that you connect all AD8HR units closer to the host than any AD824 unit. • High pass filter on/off and cutoff frequency cannot be controlled • Gain adjustment will be in 6 dB steps • [+48V MASTER] switch on/off status cannot be monitored If a computer is connected to [HA REMOTE] connector 1, set the [PC RS422] switch to PC. If you connect a Yamaha PM5D or DM2000, or another AD8HR in a multiple AD8HR system, to [HA REMOTE] connector 1, set this switch to RS422. NOTE: • If you are remotely controlling the AD8HR from a device that supports only the AD824, the device will recognize all AD8HRs as AD824s. • When remotely controlling the AD8HR from a Yamaha DM2000/DM1000, all AD8HR units may be recognized as AD824 units and some functionality may be limited unless the DM2000/DM1000 firmware is V2.0 or later. For the latest information, refer to the following website. http://www.yamahaproaudio.com/ • If you are connecting the [HA REMOTE] connectors on two AD8HRs to each other, be careful to avoid loop connection. 9  Connection Examples Connection Examples AES/EBU Connections AD8HR Daisy Chain Connection 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. Digital audio devices (PM5D, DM2000, etc.) You can connect multiple AD8HRs to a Yamaha PM5D or DM2000. Connect [HA REMOTE] connector 1 of the first AD8HR to the COM connector of the DM2000, and connect [HA REMOTE] connector 2 to [HA REMOTE] connector 1 of the second AD8HR. Set the [PC RS422] switches on both AD8HRs to RS422. Specify the DM2000 as the wordclock master, and set the wordclock source on the AD8HR to DIGITAL OUT A.

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 can also lock to the wordclock signal received at the [DIGITAL OUT A] connector or [WORD CLOCK IN] connector. AES/EBU Connections WORD CLOCK jack connection Use an AES/EBU cable to transmit digital audio data and receive a wordclock signal on the AD8HR. NOTE: In Double Channel mode, the AD8HR will run at a clock rate that is twice (88.2/96kHz) the clock (44.1/48kHz) received at the [DIGITAL OUT A] connector. In Double Speed mode, the AD8HR will run at a clock rate that is the same as the wordclock (88.2/96kHz) received at the [DIGITAL OUT A] connector. The AD8HR can receive wordclock signals at the [WORD CLOCK IN] connector.
