Digital Drive Version 2.0 New Features
Description
Allows EQing without video or EQ out hookup. Upon powering the unit up, when 3-2-1 is
pressed on the remote, the DD automatically emits 25 sweep tones. If the microphone
is connected, the unit self-EQs. Note that this only affects the low frequency EQ - it
does not affect phase, crossovers, or other settings.
New option on System Response screen. This feature resets the EQs to zero level
and default third-octave frequencies (20, 25, 32, 40, 50, 63, 80, 100 Hz), then
automatically a/- 1 dB each sweep if needed. Can be done on SETUP
(for all presets) or for an individual preset.
Each preset can have its own independent EQ setup, or all can be affected through the
SETUP selection. Also, EQ curves reflect the effect of ALL settings for each preset,
e.g. crossovers, phase, etc. Previously, these settings only reflected the SETUP values.
The low-pass crossover can be completely shut off by pressing SELECT then RESET
when the cursor is on the low-pass crossover frequency on the System Settings screen.
New field on System Settings screen - whatever preset is selected will be invoked
at startup.
Now users can use all four directional arrows to position the cursor, then press SELECT
to activate the field for alteration. For users who liked the old navigation, simply press
select and then use the left, right, up, and down buttons as before. Also, SET +/- can
be used at any time to adjust settings.
Pressing SELECT on this field freezes the SETUP column values. Previously, after
individually setting preset values, a change to the setup column would override any
individual preset changes. Users are advised to complete the global setup using the
setup values, then lock the setup column and adjust individual presets if desired.
This has been implemented by simply not erasing the previous graph until the new
graph overlays it, allowing the user to see the effect of the new settings.
Previously, the TEST button showed the user the graph screen but the only available
function was to press TEST again to return to the System Settings screen. Now the
graph screen is fully functional, and pressing TEST again puts the user at the field
where they left off on the System Settings screen.
When the volume up or down buttons are pressed, the Velodyne light will blink faster
as the volume increases, and slower as the volume decreases. Additionally, the light
will blink out the volume number - slow blinks are tens, faster blinks are ones.
So, three slow blinks followed by two faster ones indicate a volume level of 32.
The Velodyne light blinks the number of times for the selected preset (e.g. three times
for preset three).
This was introduced in release 1.6 and has been carried over to release 2.0.
The default video mode has been changed to NTSC from PAL/SECAM. To establish
PAL/SECAM video output, press the down arrow four times followed by reset on
the main screen. To restore NTSC mode, restore defaults.
