1010卡上还有其他接头，用于连接其他设备如0202子卡（1212M系统）、同步卡等。还有一对神秘的“Xcard In”和“Xcard Out”接头，名字强烈暗示着可以并连几块1010卡共同工作。虽然Emu并没有正式回答该问题，但是目前的驱动程序仅支持1块1010卡。

All the 0404's circuitry, including the Burr-Brown PCM1820 ADC and AKM AK4395 DAC chips, is on a single PCI card. Both converter chips are 192kHz-capable, but only 44.1, 48 and 96 kHz sample rates are supported here, although at this price I don't see this as much of a restriction. As on the other Emu soundcards, the mysterious Xcard In and Out connectors are present for rumoured multi-card support, as well as a Sync socket so you can attach the optional Sync daughterboard via an internal ribbon connector to add word clock in and out, SMPTE in and out, and MTC (MIDI timecode) out. I suspect these functions will be overkill for the majority of potential 0404 users, but it's a welcome upgrade option.
