10-1 External Synchronization

10-1-1 Overview

Different synchronization signals
You can use the following synchronization signals
when using the PCM-3348HR digital copying function
or for synchronized operation.
• PCM-3348HR internal clock signal
Using the PCM-3348HR as the master unit, and the
external digital audio equipment as the slave, the
PCM-3348HR supplies this signal to the external
digital audio equipment.
• Word sync signal (sector sync signal, sector
address signal)
Use these signals when phase synchronizing the
external digital audio equipment to the sampling
word signal.
• Synchronization signal included in an AES/EBU
format digital audio signal
Use this signal when making a digital copy through
the AES/EBU connector.
Below, this signal is referred to as an "AES/EBU
format synchronization signal."
• Composite video signal (composite video signal,
composite sync signal, or black burst signal)
Use this signal for synchronizing with video
equipment.

SYNC CLOCK switch
Use this switch to select the synchronization signal
used on the PCM-3348HR.
INT X'tal: PCM-3348HR highly-accurate internal
master clock signal to operate the built-in AD/DA
converter with a high quality. The variable speed
function cannot be activated.
INT NORMAL: PCM-3348HR internal master clock
to use the variable speed function.
EXT: Signal supplied by the device connected to the
WORD SYNC INPUT connector on the rear panel
of the PCM-3348HR
DI: AES/EBU format synchronization signal supplied
by the device connected to the AES/EBU D-1
connector on the rear panel of the PCM-3348HR
REMOTE 3: Signal input through the RM-3348HR
VIDEO: Signal supplied by the device connected to
the REFERENCE VIDEO INPUT connector on the
rear panel of the PCM-3348HR
When the SYNC CLOCK switch is set other
than to INT, and no external synchronization
signal is input
The PCM-3348HR uses the built-in master clock
signal for synchronization. In this case, the INT lamp
lights and the SYNC CLOCK lamp for the selected
signal flashes.
