Clock
24. Clock Synch mode: Atomic/DARS/Word/Standalone
If the Clock Synch mode* is used, please select the correct clock device.
Atomic Clock: Connect to an external atomic clock source (10MHz).
DARS: Digital Audio Reference Signal, connect to an external DARS clock reference (it
is a S/PDIF signal without any actual audio data).
Word Clock: LRCLK / WCLK of I2S Signal.
Standalone: No external clock source is used.
25. Clock Synch output
BNC multifunction Sync Out (DARS out, Word out), selection via Clock Sync mode* switch.
26. DC loop out supply
DC loop through for use with other Pro series products (e.g. Pro iCAN Signature).
27. DC power supply connection
15V/4A DC power input.
Tip: Any 9v to 18v DC power source with a minimum of 60VA rating can be used with the Pro iDSD Signature (including vehicular, RV and boat based
12V DC power). We strongly recommend the use of the included iPower Plus 15v. It offers the latest in power supply technology and is better and
cleaner than any battery or aftermarket linear power supply.
* Clock synchronization instructions:
1. Clock synchronization function is only valid when using the USB input.
2. When using USB playback:
i) When set to 10MHz (Atomic clock), the clock port must receive a 10MHz (9-11MHz) signal.
If 10MHz clock is not detected, an error will be displayed and the Pro iDSD Signature will switch back
to the internal clock.
ii) When set WLCK/DARS, the clock port input should have the following corresponding signals:
- When the USB input song frequency is a multiplier of 44100 (44100, 88200, 176400), the
sampling rate supported by the clock input is 40100hz - 48100Hz,
- When the USB input song frequency is 48000 times (48000, 96000, 192000), the clock input
supports sampling rate 44000hz - 52000Hz.
Current USB playback sampling rate is X
- If X% 44100 == 0, the supported input sampling rate: (44100-4000 / (X / 44100)) ~ (44100 + 4000 / (X / 44100))
- If X% 48000 == 0, the supported input sampling rate: (48000-4000 / (X / 48000)) ~ (48000 + 4000 / (X / 48000))
