Recording; Input Selection; Input Monitoring; Frequency Conversion - Tascam Professional CD-RW900SX Owner's Manual

Before you start recording using the CD-RW900SX, make sure
that you understand the following key points:
o Once you have recorded on a CD-R disc, the data cannot be
erased from it.
o You can add tracks to an unfinalized recordable disc. Once
finalized, a CD-R disc is "fixed" and behaves in the same way
as a pre-recorded disc. Finalized CD-RW discs, however, can
be erased, refreshed and re-recorded.

Input selection

To select the input to be recorded, press the INPUT SELECT key
on the main unit.
Repeated presses of the key cycle through the following
options:
ANALOG Analog
OPTICAL Optical digital in
COAXIAL Coaxial digital in
In the case of either the coaxial or optical inputs being selected,
the indicator COAXIAL or OPTICAL lights up.
If the analog signal is selected, the ANALOG indicator lights on
the right of the screen.
Analog recording level:
The level of the analog signals received at the ANALOG IN jacks
are controlled with the INPUT controls.
When recording analog signals, set the digital volume to 0 dB.
Digital recording level:
The level of the digital signal may be controlled using the digital
volume menu, as described below.
1.
Call up the VOLUME option in the REC sub-menu. (see
"Operation basics" on page 16)
Push the MULTI JOG dial to enter the function on.
2.
Rotate the MULTI JOG dial to adjust the input volume
between -54dB and +18 dB (relative to the original input
level).
There is also a - setting which represents a complete
signal cut. The display shows "Vol> ---dB" for the -‹ setting.
3.
Press the MENU key or push the MULTI JOG dial to enter the
setting and return to normal mode.

Input monitoring

When the unit is in record ready, or record mode, the input
signal is output from the OUT jacks (digital and analog), allowing
you to hear the input signal.
Press the RECORD key on the front panel or the remote control
when a recordable disc is not inserted.
The word "Monitor" appears on the display to show that the
output signal is an echo of the input signal(s).
Exit the monitor mode by using the STOP key.

Frequency conversion

The sampling frequency for CDs is 44.1 kHz. The CD-RW900SX
will always record (and play back) CDs at this frequency.
However, if recording through a digital connection (coaxial or
optical) and the source has been recorded at a frequency other
than 44.1 kHz, or is being played back at a non-standard speed
using a varispeed unit (more than 1% away from the standard),
the CD-RW900SX's internal frequency converter: SRC (Sampling
Rate Convertor) will automatically convert the incoming
frequency to 44.1 kHz.
To enable the SRC
Press the MENU key and select the "SRC?" option in the REC sub-
menu. (see "Operation basics" on page 16)
Rotate the MULTI JOG dial to select "ON". Press the MENU key or
push the MULTI JOG dial to enter.
NOTE
When the SRC function is off, and a digital signal is received,
the display shows the REC indicator flashing while recording
or when in recording standby mode.
The digital signals other than 44.1kHz cannot be recorded
when SRC is off. The error message "Not Fs44.1k!" will appear
on the display.
