New effects algorithms

When the VS8F-2 effects expansion board is installed, the following effects algorithms will be added.

-Making the volume consistent for each frequency band (Mastering Tool Kit) (p. 14)

-Modeling various speakers (Speaker Modeling) (p. 17)

Making the volume consistent for each frequency band (Mastering Tool Kit)

This is a compressor that can be applied independently to each frequency band (high, mid, and low ranges). When mastering to MD or DAT,

or when using a CD-R disc to produce your own original audio CDs, this allows you to master at the optimal level.

The mastering tool kit can be used in either EFX1 or EFX3. When

you use it, EFX2/EFX4 will be unavailable.

EQ (Equalizer)

This is a four-band equalizer with low, low-mid, high-mid,

and high ranges.

Sw (Switch) Off, On

Turns the equalizer on/off.

InputG (Input gain) -24–+12dB

Adjusts the overall volume level of the signal before entering

the equalizer.

Low Type Shlv, Peak

High Type Shlv, Peak

Selects the type of the low range (Low) and high range

(High) equalizer. (Shlv: shelving type, Peak: peaking type).

Low Gain -12–+12dB

LoMid Gain (Low middle gain) -12–+12dB HiMid Gain (High middle gain) -12–+12dB High Gain (High gain) -12–+12dB

Adjust the gain (the amount of boost or cut) for each

equalizer band.

Low Freq (Low frequency) 20–2,000Hz

LoMid Freq (Low middle frequency) 20–8,000Hz

HiMid Freq (High middle frequency) 20–8,000Hz

High Freq (High frequency) 1.4–20kHz

Adjust the center frequency of each equalizer band.

Low Q (Low Q) 0.3–16

LoMid Q (Low middle Q) 0.3–16

HiMid Q (High middle Q) 0.3–16

High Q (High Q) 0.3–16

Adjust the width of the area around the center frequency (Freq) that will be affected by the Gain. As these values are raised, a narrower range will be affected.

Lvl (Level) -24–+12dB

Adjusts the overall volume of the signal that has passed through the equalizer.
