I/O Card Specifications 253 I/O Card Specifications Specifications for the currently available I/O cards are as follows. Card Format In Out A/D D/A Wordlength Connectors MY8-AD Analog input 8 MY4-AD Analog input 4 MY4-DA Analog output - MY8-AT ADAT 8 MY8-AE AES/EBU 8 MY8-TD Tascam TDIF-1 8 - 20-bit, 128 times - - Phone jack (balanced) x8 - 24-bit, 128 times - - XLR-3-31 type (balanced) x4 4 - 20-bit, 128 times - XLR-3-32 type (balanced) x4 8 - - 16, 20, 24 Optical x2 8 - - 16, 20, 24 25-pin D-sub (cable not included) 8 - - 16, 20, 24 25-pin D-sub BNC wordclock output As these specifications show, analog I/O cards offer either inputs or outputs, while digital I/O cards offer both inputs and outputs. Choosing I/O Cards The DME32 features four I/O slots, for a total of 32 inputs and 32 outputs, which correspond to the slots as follows: DME32 Slot 1 2 3 4 DME32 Channels Inputs Output 1-8 1-8 9-16 9-16 17-24 17-24 25-32 25-32 The type of cards you choose affects the number of channels that can be accessed. To access all 32 inputs and all 32 outputs, for example, you need to install four digital I/O cards. If you install four MY8-AD 8-channel analog input cards, for example, you can access all 32 inputs but no outputs. Analog access to all 32 inputs and all 32 outputs can be achieved by using Yamaha AD824 DA Converters and Yamaha DA824 DA Converters. See "AD824 & DA824 Converters" on page 256 for more information. Analog and digital I/O cards can be combined, so you could for example, install two MY8-AD 8-channel analog input cards in slots 1 and 2, providing analog access to input channels 1 through 16, and install two digital I/O cards in slots 3 and 4, which would provide digital access to input and output channels 17 through 32. Any of the four I/O slots can be selected as the external wordclock source when using digital I/O cards. See "Selecting the Wordclock Source" on page 229 for more information. To connect the DME32 to other digital audio equipment, you must determine which digital interconnect format-AES/EBU, ADAT, or Tascam TDIF-1-the other equipment supports, and then install the necessary I/O cards in the DME32.
