Please connect it to the INPUT connector. E2: The INPUT connector of the DIO8 is connected to the INPUT connector of the DSP unit. Please connect it to the OUTPUT connector. (This will not be displayed if the OUTPUT connector of the DIO8 is connected.) E3: Either the cable connected to the INPUT or OUTPUT connector has become disconnected, or the connection destination is incorrect. If the connection is correct, try replacing the cable. (This will be displayed only if both INPUT and OUTPUT are abnormal.) UC: Control signals are not being received correctly. Make sure that the power of the DSP unit is on. These error displays indicate an error for the INPUT/ OUTPUT A connectors if the PORT B SELECTOR switch is set to 5-8, and indicate an error for the INPUT/OUTPUT B connectors if the PORT B SELECTOR switch is set to 1-4. Even if there is an incorrectly connected connector, the error display will not appear if there is another control connector that is usable. UL: The word clock is not locked. Make sure that the word clock source is selected correctly, and that the cable is connected correctly. Note: You can change the PORT B SELECTOR setting by sending the control signal from the CS1D. At this time, two dots (“. .”) light up besides the indicator message described above. If the PORT B SELECTOR switch setting on the unit is different from the actual operation, one of the following messages and the indicator message described above will appear alternately. • If the PORT B SELECTOR switches to slots 1-4: “ ” • If the PORT B SELECTOR switches to slots 5-8: “ ” B PORT B SELECTOR switch Use this switch to select slots 1-4 or slots 5-8 to assign the INPUT A/OUTPUT A connectors (referred to as PORT A) and the INPUT B/OUTPUT B connectors (referred to as PORT B). PORT B SELECTOR is set to “5-8” Slot 1 Slot 2 Slot 3 Slot 4 INPUT A OUTPUT A Error displays If the PORT B SELECTOR is set to 1-4, only PORT B is available for input and output signals via slots 1-4. In reality, slot 1-4 input signals are routed to OUTPUT A, and the INPUT B signal is output to slots 5-8. If you wish to route slot 1-4 signals to both OUTPUT A and B, use this setting. Slot 5 Slot 6 Slot 7 Slot 8 INPUT B OUTPUT B This indicates the connector number (the number of the connector used to control the DIO8) of the engine DSP unit (DSP1D/DSP1D-EX) connected to the DIO8. If more than one connector is connected, either A or B will be automatically selected as the connector for control, according to the connection status of the INPUT and OUTPUT jacks. If there is a problem such as an incorrectly connected DSP unit or if the word clock is not locked, this will be indicated by one of the following error displays. If the PORT B SELECTOR is set to 5-8, slots 1-4 are assigned to PORT A and slots 5-8 are assigned to PORT B for input and output signals.

Slot 1-4 input signals will be output from OUTPUT A and B. However, the output signal will be the same as the signal input to INPUT B. C POWER ON/OFF switch Use this switch to turn the power to the DIO8 on and off. When the power is turned on, the I/O UNIT ID indicator lights up. D WORD CLOCK IN jack, ON/OFF switch The WORD CLOCK IN jack is used to provide word clock to the DIO8 from a clock generator or a connected external device. Use a BNC cable with an impedance of 75 Ω for connection. The WORD CLOCK ON/OFF switch is used to terminate the word clock connection. Basically, if the DIO8 is the last device of the word clock chain, or if nothing is connected to the WORD CLOCK IN/OUT jacks, set this switch to ON. E WORD CLOCK OUT jacks The WORD CLOCK OUT jacks are used to provide word clock from the DIO8 to the connected external device, such as digital MTR or DAT recorder. Use a BNC cable with an impedance of 75 Ω for connection. Caution: If you are using the MY8-AT card to handle ADAT format signals, synchronization may tend to be lost easily depending on the device that is connected. For the most reliable synchronization, we recommend that the word clock for digital audio devices being used together be taken from a connector other than the ADAT-format connector, such as this connector. F COM port This connector is provided for future system expansion, but it is not operative in the current software version. G OUTPUT connectors A (1-4)/(1-8), B (1-4/ 5-8) These connectors are used to output multi-channel digital audio signals to the DSP1D/DSP1D-EX. Depending on the setting of the PORT B SELECTOR, assignment between the OUTPUT A and B connectors and slots 1-8 varies. For more information, refer to 2 PORT B SELECTOR. Be sure to use the included genuine Yamaha half-pitch 68-pin cable for connection. Optional genuine Yamaha cables in a variety of lengths are also available. H INPUT connectors A (1-4)/(1-8), B (1-4/5-8) These connectors are used to input multi-channel digital audio signals from the DSP1D/DSP1D-EX.
