SYS/W.CLOCK function Note • For the DSP5D, you cannot select 2TR IN D1-D3 or SLOT 3-4. For CASCADE IN, you can choose either the D-sub 68pin connector or the RJ-45 connector. • If you make cascade or other connections using the DCU5D's CASCADE OUT (RJ-45) connector, it will not be possible to synchronize to the word clock from the DCU5D's CASCADE OUT (D-sub) connector. In this case, you'll need to provide a separate connection for the word clock. The operational status of each clock is shown by the color of the symbol at the left of each button. Each color has the following significance. • LOCK (blue) This indicates that a clock synchronized with the source selected in (2) is being input. If an external device is connected to the corresponding connector or slot, input/output is occurring normally between that device and the PM5D. If the sampling frequency is close, this status may be displayed even if not synchronized. • UNLOCK (red) A valid clock is not being input. If an external device is connected to the corresponding connector, input/output cannot occur correctly between that device and the PM5D. • LOCK, BUT NOT SYNC'ED (orange) A valid clock is being input, but is not synchronized with the clock source selected in (2). If an external device is connected to the corresponding connector, input/output cannot occur correctly between that device and the PM5D. • UNKNOWN (yellow) This indicates that the clock status cannot be detected because no external device is connected or because there is no valid clock input. You will be able to select this connector/slot, but successful synchronization cannot occur until a valid connection is established. • SRC ON (green) This is a special status only for SLOT 1-4 and 2TR IN 2TR IN D1-3, indicating that the corresponding channel's SRC (Sampling Rate Converter) is enabled. This means that even if the signal is not synchronized, normal input/output with the PM5D is occurring. Note • Noise may occur at the output jacks when the word clock setting is changed. In order to protect your speaker system, be sure to turn down the power amp output before changing the word clock setting. • If you attempt to select a channel whose SRC is on as the word clock master, a message will appear, warning you that the sampling rate converter will be disabled. B Fs (Sampling frequency) This indicates the sampling frequency at which the PM5D is operating. This will indicate "UNLOCKED" while synchronization is lost (such as immediately after switching the master clock). 34 5 67 8 C Slot number / Card type This area shows the type of digital I/O card installed in slots 1-4. D INPUT FORMAT (Input signal format) E OUTPUT FORMAT (Output signal format) Select one of the following as the method by which signals will be exchanged with a digital I/O card installed in the slot when the PM5D is operating at a high sampling rate (88.2/96 kHz). • SINGLE This setting allows transmission/reception of the normal number of channels when existing equipment that operates at 44.1/48 kHz is connected. The sampling rate will be converted for each channel of the digital I/ O card, and transmitted/received at half the sampling frequency (44.1/48 kHz) of the PM5D. (This setting can be selected only for slots in which a digital I/O card that does not support 96 kHz is installed.) • DOUBLE SPEED This setting allows high sampling rate audio signals to be transmitted/received without change when equipment that operates at a high sampling rate (88.2/96 kHz) is connected. (This setting can be connected only for slots in which a digital I/O card that supports 96 kHz is installed.) • DOUBLE CHANNEL This setting allows high sampling rate (88.2/96 kHz) audio signals to be handled when existing equipment that operates at 44.1/48 kHz is connected. Two channels of signals at half the PM5D's sampling frequency (44.1/48 kHz) are transmitted/received together as a high sampling rate monaural signal. (The number of usable channels will be half.) F FREQUENCY (Sampling frequency) This indicates the sampling frequency of the signal being input to each channel of the digital I/O card, in sets of two channels. G SRC (Sampling Rate Converter) This button switches the Sampling Rate Converter on/ off, in sets of two channels. This is available only for slots in which a digital I/O card with a built-in sampling rate converter is installed. H EMPHASIS STATUS This indicates whether emphasis is applied to the input signal, in sets of two channels. This is available only for slots in which a digital I/O card is installed. 220 PM5D/PM5D-RH V2 / DSP5D Owner's Manual Reference section
