DIR (COAX) (default) It is possible to evaluate the AK4387 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the received data through RCA connector (J3). Setting of jumper is shown below. COAX is recommended for an evaluation of the Sound quality. JP1 OPT COAX RX (Default) Figure 2. Jumper setting, when using DIR 2. DIR (Optical Link) It is possible to evaluate the AK4387 by using CD disk. The DIR generates MCLK, BICK, LRCK and SDATA from the received data through optical connector (PORT3: TORX173).
