Attenuation
You can adjust the overall volume of each channel of the
Input Mixer and the Track Mixer without using the channel
faders. You can lower (attenuate) the volume of a track that is
much louder than the others or increase the overall volume
of tracks that were recorded at too low a level. This makes
adjusting mix levels easier.
1.
Press the SELECT button for the track (or input) you
want to attenuate or boost. The Track SELECT button
lights, and the Track Mixer screen appears in the display.
2.
Use [ ], [ ], [ ], and [ ] to move the
cursor to “ATT.” Or, press [F2 (ATT)]. If “ATT” does not
appear in the display above [F2], press [PAGE] until
“ATT” appears above [F2], then press [F2 (ATT)].
3.
Use the TIME/VALUE dial to change the setting.

Phase
The VS-1680 features balanced (TRS) INPUT jacks. The pin

fig.11-41
Some audio devices employ the opposite HOT (TIP) and
COLD (RING) wiring. Using such equipment as is may result
in poor sound placement, loss of correct left-right balance,
and loss of separation between left and right channels when
using stereo inputs. In such cases, you need to switch the
phase of each channel.
1.
Press the SELECT button for the track whose phase you
want to switch.
The Track SELECT button lights, and the Track Mixer
screen appears in the display.
2.
Use [ ], [ ], [ ], and [ ] to move the
cursor to “Phase.” Or, press [F3 (Phase)]. If “Phase” does
not appear in the display above [F3], press [PAGE] until
“Phase” appears above [F3], then press [F3 (Phase)].
3.
Use the TIME/VALUE dial to change the Phase setting.
Phase
This selects the Phase (NRM, INV) for the channel.
Usually “NRM” is selected.
NRM:
Normal phase (same phase as input). Default setting.
INV:
Inverted (opposite) phase.
4.
Press [PLAY (DISPLAY)] to return to the Playlist display.
When Phase Mismatch is a Problem
Audio equipment connected as shown below will result in
audio being out of phase. In such cases, select “INV.” It is
recommended that you check the HOT and COLD leads for
all of your audio equipment.

When Phase Mismatch is Not a
Problem
