ROMs are sensitive to the number of times they are overwritten, but this would only be a problem if
this feature were used 1000x times.
2. What happens when the battery runs out?
Among a host of other components, the SX-1 s internal architecture includes a central processing unit
based around a PC motherboard. Like a PC, the motherboard has a battery used to store system data
when the SX-1 is either powered off or unplugged, and just as in a PC, this battery will run down over
time, with a life expectancy of 4-5 years. To give you an idea what happens when the battery finally
dies, we removed the battery completely and started the machine.
The VGA will initially display this message:
CMOS Setting Wrong
CMOS/GPNV Checksum Bad
Press F1 to Run SETUP
Press F2 to load default values and continue
At this point, all you need to do is press F2. The SX-1 is unique, in that it has a custom BIOS whose
default values are the correct ones to operate properly — when the battery dies you can simply reload
the default BIOS settings and continue working. This assumes that the VGA output is being displayed
on a monitor, and a PS/2 keyboard is connected.
Once it boots up from this state, the only difference you will notice from normal operation is that the
clock has been reset to January 1
clock, which will work normally until you power down (at which time it will reset again for lack of
battery power).
The battery is a standard PC-type CR2032, which is available not only from TASCAM service but
from many computer shops as well.
3. Flickering display with an SVGA monitor.
Depending on the unit, connecting a 15 (or larger) flat panel LCD monitor can result in flickering
displays on the Waveform tabs and Track screens when the transport is moving. This is due to an
interaction between the refresh rate of the SX-1 and the natural response of the LCD monitor. The SX-
1 can set its VGA refresh rate to any of the following: 60, 70, 75, 85, and 88Hz.
LCD displays can usually accommodate a refresh rate in the 60-75Hz range, but a lower value can
often produce a more stable display. It is a good idea to try all of the available rates and pick the one
that exhibits the least amount of flickering. A CRT monitor on the other hand, always looks best when
it is being driven with the fastest refresh rate this it supports. The internal LCD display has been
calibrated
4. Complete rundown of audio file compatibility.
The following is a summary of the audio file format compatibility in SX-1 V1.50.
NOTE: The first section consists of a list of the supported audio files for playback — meaning that
these are the only files that should be located in a project s Audio Files folder. Audio files can be
mono only, and will be played back as mono. The sample rate of the audio file will be ignored once
inside a mix, and will playback at the project s sample rate — meaning that the pitch/speed of the audio
file in question will be incorrect unless it is played back at the same rate at which it was recorded.
Supported file types for playback:
