5 - Operation De-esser Release 200 ms The Release Time control adjusts the time it takes the compressor element's gain to increase 6 dB after the signal coming from the highpass filter drops below the threshold. The range of the control is from 20 milliseconds to 2550 milliseconds. (The default setting is 120 milliseconds.) ªª High Pass Frequency Page Pressing the HI-PASS button brings up this page: De-esser Highpass Frequency: 5402 Hz The de-esser can be viewed as a compressor which is keyed by the output of a high pass filter. When the filter passes a signal whose level is higher than the compressor's threshold, the compressor clamps down on the signal. Since sibilants are primarily broad band noise above 5 kHz, the filter is designed to pass these signals and attenuate low frequency signals as much as possible. The filter used in TA-1VP's de-esser is a two pole, 12 dB/ octave high pass design which effectively distinguishes between sibilants and other vocal sounds. The range of the control is from 2971 Hz to 20 kHz. (The default setting is 5497 Hz.) ªª De-esser Gain Reduction Meter Page DeS:-20 -12 -6 -3 0 Pressing the DE-ESS button while the De-esser page is displayed will display this high resolution gain reduction meter. The meter displays the amount of de-essing of the signal. If the frequency and threshold controls are set properly, the meter will display little gain reduction during vowel sounds and soft consonants, and substantial gain reduction during sibilants. Pressing the DE-ESS button again will return to the De-esser page. ªª Gain Reduction Meter The front panel de-esser GAIN REDUCTION meter is intended to provide a quick indication of de-esser activity. For precise gain reduction indication, refer to the De-esser Gain Reduction Meter Page described above. The range of the meter is 15 dB. ªª De-esser ON Button When this button is lit, the De-esser module is active. When it is not lit, the module is bypassed. Pressing the button toggles its state. The De-esser On/Off function can also be controlled by MIDI and/or by a footswitch. EQUALIZER/OUTPUT MODULE ªª EQ #1 Page Pressing the EQ BAND 1 button brings up this page: EQ1 Peaking f: 7725 Q:2.4 Gn:+12 This page allows you to select the type and set the parameters of the first of the TA-1VP's two bands of parametric equalization. Use the Data Knob to select the type of equalization (default setting is High Shelf ) and then use the cursor buttons to move to the various parameters available for that type. The equalization types and their associated parameters are as follows: ªª EQ Off EQ1 (off) No equalization applied. ªª Low Shelf Filter EQ1 Low Shelf f: 1000 S:1.0 Gn: +6 The Low Shelf filter can be thought of as the world's most flexible version of the venerable "Bass" tone control familiar to users of radios, home stereos and boom boxes. The Low Shelf filter boosts or cuts all frequencies below cutoff frequency "f" by the Gain ("Gn") amount (in dB). Additionally, you can vary the slope ("S") of the shelf from 2 dB/octave (S=0.3) to 12 dB/octave (S=2.0). ªª High Shelf Filter EQ1 High Shelf f:11039 S:1.5 Gn: +4 The High Shelf filter can be thought of as the world's most flexible version of the venerable "Treble" tone control familiar to users of radios, home stereos and boom boxes. The High Shelf filter boosts or cuts all frequencies above cutoff frequency "f" by the Gain ("Gn") amount (in dB). Additionally, you can vary the slope ("S") of the shelf from 2 dB/octave (S=0.3) to 12 dB/octave (S=2.0). TASCAM TA-1VP 31
