[. . . ] Increasing the value of this parameter creates an increasing "live"sound, simulating an increasing area of reflective surfaces in the room. Diffuse (Diffusion: 0 ~ 1 0 ) Refers to the clearness of the sound. As the value is increased, the complexity of the reflections increases producing a thicker and richer sound. IniDly (Initial Delay Time: 0. 1msec ~ 400msec) Initial delay is the time between the beginning of the direct sound and the beginning of the early reflection. HPF (High Pass Filter Frequency: THRU, 32Hz ~ 1. 0kHz) Permits rolling off the low frequency content of the reverb signal above the set frequency. LPF (Low Pass Filter Frequency: 1. 0kHz ~ 16kHz, THRU) Permits rolling off the high frequency content of the reverb signal above the set frequency. Er Number (Early Reflection Number: 1 ~ 19) This parameter directly sets the number of early reflections produced from 1 to 19. FbDly (Feed Back Delay Time: 0. 1msec ~ 900msec) The parameter sets a delay time between the beginning of the original early reflections and the first of the repeats caused by feedback. Shorter FbDly times simply thicken the early reflection sound while longer FbDly times can create extended or repeated early reflection effects. FbGain (Feed Back Gain: -99% ~ +99%) The parameter determines how many times (for how long) the early reflection are repeated. The lower the setting, the lesser is the feed back. High (High Frequency Feed Back Gain: 0. 1 ~ 1. 0) Controls feedback Fb1 and Fb2 in the high frequency range. The high frequency feedback is reduced as the value of this parameter is decreased. HPF (High Pass Filter Frequency: THRU, 32Hz ~ 1. 0kHz) Permits rolling off the low frequency contents of the reverb signal above the set frequency. Fb1Gain (Feed Back 1 Gain: -99% ~ +99%) Sets the amount of Fb1 fed back to the input of the processor. The higher the feedback gain setting, the greater the number of delayed repeats produced by the corresponding feedback loop. LPF (Low Pass Filter Frequency: 1. 0kHz ~ 16kHz, THRU) Permits rolling off high frequency content of the reverb signal above the set frequency. The LPF is OFF when set to THRU. 30 Echo (Echo) 1in/2out The echo effect offers independently variable left and right echo intervals. Parameters L. FbDIy (Lch Peed Back Delay: 0. 1msec ~ 740. 0msec) Sets the time between the echo sound and the first repeat heard from the left channel. L. Fb (Lch Feed Back Gain: -99% ~ +99%) Individually set the amount of the left channel echo signal fed back to the left channel input of the processor. The lower the feedback gain setting, the smaller the number of echo repeats produced by the feedback loop. R. FbDIy (Rch Feed Back Delay: 0. 1msec ~ 740. 0msec) Sets the time between the echo sound and the first repeat heard from the right channel. R. Fb (Rch Feed Back Gain: -99% ~ +99%) Individually set the amount of the right channel echo signal fed back to the right channel input of the processor.
