For example when the Release control is set at 100 ms the limiter s attenuation Will release at the rate of 100 ms per dB or viewed in another way it would release 10dB over 1 second of time The attack and release time action was designed this way to achieve a more natural attack and release behavior of a constant rate rather than time It should be noted that fast attack and release times may distort the audio signal This occurs in any limiter because a fast attack or release action changes the gain rapidly which will by definition distort the waveshape of long wavelength low frequency signals Therefore it is recommended that longer attack and release times be used for lower distortion 10 segment meters on the LCD indicate amount of GAIN REDUCTION and OUTPUT LEVEL including a Peak LED on the output meter As with EQ and all other audio functions the limiter is enabled by the In Out key 5 3 3 HPF LPF The HIGHPASS and LOWPASS filters of fer precise frequency adjustment of two 24dB oc tave filters creating accurate visual representation of the pass band The frequency indicated for each filter is the 3dB point Use the four softkeys to shift the frequency for each filter To quickly shift both filters off while in this menu press the FLAT key to the right of the display 5 3 4 DELAY The DELAY feature is used to time align two or more loudspeaker sources so that the acoustic energy created by different speakers at different
