4 BAND EQ (4 band equalizer)
This effect is the equalizer, which can adjust the 4 frequency bands to correct or process the sound.
Low/Hi EQ is a shelving type equalizer, which boosts or cuts the frequencies higher or lower than the specified
frequency.
The Mid1/2 is a peaking type equalizer, which boosts or cuts the specified frequency and the harmonics
surrounding the frequency.

COMPRESSOR
This effect compresses sound which exceeds a certain level, to make the sound levels even.
Threshold field: any signals, which exceed the level set here, will be compressed. The lower the value is, the
better the result will be.

PHASE SHIFTER
This effect adds sounds with different phases to the original sound, to create a swelling or rotating sound.

You can set the low frequency range.
You can adjust the gain of the low frequency range.
You can set the frequency of the mid frequency range 1.
You can set the gain of the mid frequency range 1.
You can set the band range of the mid frequency range 1.
You can set the frequency of the mid frequency range 2.
You can set the gain of the mid frequency range 2.
You can set the frequency range of the mid frequency range 2.
You can set the frequency of the high frequency range.
You can set the gain of the high frequency range.
You can adjust the overall level here. As you lower the value in the Threshold field, the
overall level is also lowered. You can adjust the final level in this field.
You can set the compression ratio here. The larger you set the value, the greater the
compression becomes and you can make the overall level even.
You can set the time it takes to start the compression after the incoming signal
exceeds the level set in the Threshold field.
You can set the time it takes to finish the compression after the incoming signal falls
below the level set in the Threshold field.
You can set the speed of the modulation here.
You can set the amount of the phase shift of L and R. If you set this field to 00, L and R
will be in sync. As you increase the value, the phases of the L and R will shift and you
can create the complicated effect.
You can set the feed back level from the output to the effect input. The effect will be
boosted and create more a unique sound.
You can set the depth of the modulation here.
You can set the center frequency for the phase shift. If you set this value high, the
phase shift will be applied around the high frequency range.
If you set it to ON, the Sweep rate will be set at the same cycle for both the Left and
Right. If you set to OFF, the sweep rate of the right channel will be set slightly higher
than that of the left channel. You will be able to create a more complicated effect.
