BASIC FUNCTIONS

Q: What are the main differences
between VS-2400CD and
VS-1880/1824?
A: Main differences from VS-1880/1824 are as follows.
• Accommodates 96kHz sampling rate
• 24-bit linear recording
• An R-BUS port
• Newly developed pre-amp circuit on analog input
• 13 motorized faders
• Mouse operation on VGA screen
• 3.5" hard disk drive installed with expanded partition
size to 10GB
• Dynamics processor (Compressor/Expander) equipped
on every mixer channel
• 4-band EQ
• Surround panning function
Q: About the Recording Mode
A:
• M24 (Mastering 24bit)
Audio from the analog inputs that passes through the
VS-2400CD's 24-bit A/D converter, and audio data from
the 24-bit digital inputs will be recorded and played as
linear data.
When this mode is selected, the VS-2400CD will function
as a 16-track recorder (tracks 1–16). When sampling
frequency is more than 64kHz, the VS-2400CD will
function as a 8-track recorder.
• MTP (Multi Track Pro)
Audio from the analog inputs that passes through the
VS-2400CD's 24-bit A/D converter, and audio data from
the 24-bit digital inputs will be recorded and played
using proprietary Roland coding technology (R-DAC).
Normally you should select this mode.
• CDR (CD-R Writing):
This mode allows you to directly create a CD image file
on your hard disk – this file can later be burned onto a
CD-R. Recording and play back will occur using 16-bit
linear data similar to that of a CD player or DAT
recorder. In CDR mode, Tracks 1–8 are linked in
odd/even fader pairs, with their levels controlled by the
odd-numbered fader. Track 17–24 cannot be used.
• M16 (Mastering 16bit):
Recording and play back will occur using 16-bit linear
data similar to that of a CD player or DAT recorder.
When this mode is selected, the VS-2400CD will function
8
as a 16-track recorder (tracks 1–16). When sampling
frequency is more than 64kHz, the VS-2400CD will
function as a 8-track recorder.
• MT1 (Multi Track 1):
This recording mode provides approximately twice the
recording time of M16 mode.
• MT2 (Multi Track 2):
This recording mode provides even longer record times
than MT1.
• LIV (Live 1):
This mode is appropriate when your hard disk lacks free
space or when recording live performances where the
total recording time is unknown.
• LV2 (Live 2):
This mode provides the longest recording time. This
mode is appropriate for live recordings of speeches, and
recordings made for reference purposes. Use this mode if
you have very little drive space left or you aren't sure
how long the recording will be.
Q: Is it possible to mix down even
when all the 24 tracks are occupied?
A: Yes. In the Mastering Room, you can mix down to the
empty V-tracks on tracks 23/24 while playing back 24 tracks.
Q: How long is the recording time?
A: Recording time in each recording mode and sampling rate
is as shown in the following table. (unit: minute)
