Tascam 2488neo owner manual Using the mastering EQ/noise shaper, ªª Saving compressor settings

8 − Mastering and CD recorder

ªª Saving compressor settings

Use the following procedures to save mastering tool com- pressor settings as a user patch.

1With the compressor screen open, press the YES/ ENTER key to open the MASTERING TOOL

LIBRARY screen.

3Use the JOG/DATA dial to select the save destina- tion.

If you select an existing library patch, it will be overwritten by the new data.

Select (new lib) to save a new patch in the library data without overwriting another patch.

4Press the YES/ENTER key to save the patch in the library and return to the MASTERING TOOL screen (compressor screen).

NOTE

If you press the NO/EXIT key instead of the YES/ENTER key, the MASTERING TOOL screen (compressor screen) will reopen without saving a patch.

You can give the patch a name (see “Titling” on page 15).

2 Use the > cursor key to select SAVE.

Using the mastering EQ/noise shaper

1When the MASTERING TOOL screen is open, press the Á cursor key to select the EQ/NS tab and open the EQ/noise shaper screen.

FREQ: Frequency in the following ranges

L:32 Hz – 1.6 kHz

M:32 Hz – 18 kHz

H:1.7 kHz – 18 kHz Q (only MID): 0.25 – 16

NOTE

Q is a value found by dividing the center EQ frequen- cy by the bandwidth. The higher the Q value is the smaller the range of the cut/boost effect.

ªª Noise shaper

2Use the cursor keys and JOG/DATA dial to select parameters and adjust them.

NOTE

When the cursor is on the SW item of the EQUAL- IZER or the NOISE SHAPER, pressing the Ó cursor key switches to the compressor screen.

ªª Settings the EQ

The parameters and setting ranges of the mastering 3-band EQ are the same as for the channel EQ. The low band (L) and high band (H) are shelving type bands that have GAIN and FRQ (roll-off frequency) parameters that can be set. The mid band (M) is a bell type band with GAIN FRQ (center frequency) and Q (band width–see note below) parameters that can be set.

SW: Switch that turns EQ ON and OFF

GAIN: Amount gain is cut or boost ± 12dB

Audio CDs use 16-bit quantization, so the master track data is automatically converted to 16-bit.

Ordinarily, bit conversion results in a very low level of quantization distortion at points where sound is removed. By turning the noise shaper ON, this quantization distor- tion can be reduced.

The noise shaper in this unit uses a dithering technique that adds random noise below the quantization steps to reduce quantization distortion.

ªª Noise shaper setting

The noise shaper can be turned ON and OFF using the SW item at the bottom left of the screen.

NOTE

EQ and noise shaper settings cannot be saved in the library.
