6 – Effects
The DV-RA1000 incorporates two signal processors:
a 3-band equalization stage and a dynamics proces-
sor. These can be inserted either before the final
recording process (post-AD conversion) or on play-
back (pre-DA conversion).
These effects can be used on playback to simulate the
effects of pre-mastering effect processing before the
mixed stereo track is actually pre-mastered in another
Setting up the effect position
The
key is used to switch the effects on and
EFFECT
off, to set up the parameters, and to set up the posi-
tion of the effect in the signal chain.
Press and release the key to turn the effect chain on
and off (the indicator shows the status).
Press, hold and release the key to bring up the first
setting screen:

Equalization
The equalization effect has three bands: a shelving
sweepable low, a fully parametric mid, and a shelv-
ing sweepable high.
All bands can cut or boost ±12 dB. The slope of the
low and high bands is 6 dB/octave.

facility, or may be even used to perform the actual
premastering.
Equalization is carried out a 40-bit resolution, and
dynamics processing is carried out at 32-bit resolu-
tion at the same sampling frequency as the current
project.
NOTE
The effects are not available in quad-frequency or DSD
modes.
Use the wheel to change the effect position between
the playback (
PLAYBACK
) and recording positions
(
RECORD
).
Use the cursor keys to navigate to the
OUTPUT LEVEL
fields, and use the wheel to set the val-
ues of these parameters (that is, the input attenuation
before the signal enters the effects section and the
attenuation after the signal leaves the effects section).
These levels can be set from
INF
(infinity, i.e. no sound), in 0.5 dB steps from 0 dB
to –10 dB and in 1 dB steps thereafter.

The output level from the EQ effect (which
feeds the dynamics processor) is shown by the
meters at the right of the response curve.
NOTE
Since each band is capable of boosting the level by
12 dB in the digital domain, you should take care not to
overload the outputs.
