2-4-1 Switch Settings on the System Control Block of the PCM-3348HR

The upper right part of the control panel of the PCM-
3348HR includes twelve switches. When the leftmost
MASTER SAFE switch is in the upper position, it is
on and the MASTER SAFE lamp lights. All of the
other switches operate by changing the setting each
time they are pressed downward.

2-4-2 Selecting the Word Length

Select either 24 bits or 16 bits using the WORD
LENGTH selector in the system control block.
Tapes recorded with a word length of 16 bits are
compatible with those recorded with conventional
DASH-format devices.
Note
Unlike that of the sampling frequency, the value of the
word length used in recording is not automatically
selected in playback. Be sure to select an appropriate
value before starting playback.
2-4-3 Selecting the Sampling
Frequency
Sampling frequency for prestriping or
advance recording
With the Fs switch on the system control block, select
44.056 kHz, or 48.0 kHz. The selected frequency is
recorded on the CTL track on the tape as the Fs ID

also set as the AES/EBU digital I/O Fs ID code, and as
the sampling frequency for internal operation in the
PCM-3348HR.
Setting the FS SHIFT switch on the CTK board to ON
switches to Fs shift mode, and when the sampling
frequency selected on the system control block is 44.1
kHz or 48.0 kHz, the 44.1 kHz or 48.0 kHz lamp
flashes. In this case, the sampling frequency used for
internal operation of the PCM-3348HR shifts down
from the selected frequency by 0.1 %. The Fs ID
code, however, remains at the setting on the system
control block.
Sampling frequency other than for
prestriping or advance recording
For insert recording, assemble recording, or playback,
both the AES/EBU digital I/O Fs ID code and the
sampling frequency used for internal operation are
automatically set to the sampling frequency recorded
on the CTL track.
