TASCAM 2488neo 31
5 − Mixer
In this section, we explain the channel functions of the
2488neo’s mixer. The recorder track channels (1–24) and
input channels have similar functions, so we explain them
together as channel functions. Stereo bus functions are
explained on page 33.
Channel functions
EQ
Press the EQ key to display the EQ screen for the current
channel. To change the channel, press the INPUT key or
SELECT key of the desired channel.
ª
Digital pad/gain
Press the channel’s SELECT key, followed by the EQ key
(this order can be reversed). Use the cursor keys to navigate
to the PAD/GAIN area, and set the value to between –42 and
+6 dB.
This is usually set at 0 dB, but when boosting EQ, we recom-
mend that you lower the gain to prevent digital clipping.
Use this to add volume to a quiet instrument or to remove
excess volume from a loud one. When a channel’s EQ
screen is shown, simply pressing the SELECT key of
another channel will show the EQ screen for that channel.
ª
EQ
Set the three-band equalization for each channel using the
same screen as the digital pad/gain (see above). On the
2488neo channels, you can adjust the gain (the amount that
the signal is cut and boosted) by ±12 dB, and the frequency
(high or low) affected by the equalization in three bands.
The frequencies are (in Hz):
Low (L) 32 — 1.6k
Mid (M) 32 — 18k
High (H) 1.7k — 18k
Note that the frequencies are set in discrete steps; it is not
possible to set the center frequencies to intermediate val-
ues. In addition, you can adjust the “Q” (the width of the
effect) in the center band from 0.25 to 16.
TIP
“Q” is defined as the center frequency of the equaliza-
tion band divided by the bandwidth. A high Q value
provides narrow filtering.
As you adjust the equalization, the graph at the bottom of
the screen changes to provide an idea of how the equaliza-
tion affects the signals.
TIP
With the SHIFT indicator lit, press the EQ key to restore
all channel EQ parameters to their initial settings.
There is also an on/off soft switch provided at the upper
left of the screen to allow A/B comparison of the equal-
ized and unequalized signals. With the SHIFT indicator lit,
press YES/ENTER to turn it on, and NO/EXIT to turn it off
(you can also use the cursor).
Each of the 24 channels provides the following facilities:
Digital pad/gain
•
3-band parametric EQ
•
Effect sends
•
Phase reversal switch
•
Pan-pots
•
A physical fader (which may be overridden by an
•
internal “virtual fader”)
A mute key
•
Solo facilities
•
Like the 24 track channels, the eight inputs are provided
with phase, digital pad/gain, EQ, effect sends, etc. They
are not provided with physical faders, but the output from
these “extra channels” can be adjusted on-screen. Although
these settings can be made at any time, they are only effec-
tive when the inputs have been assigned to the sub mixer.
See “Sub mixer” on page 35 for details.
