Since the above reverberation parameters are optimised to ensure authentic acoustical
simulation, they are by necessity program-dependent.
Controls
Input mute Removes audio feed from reverberation section.
Reverb mute Clears unwanted reverberant signal.
Input level control From 6dB gain to infinite attenuation.
Headroom indicator 10-point LED display, 0dB to -27dB.
Display Simultaneous display of all parameter information.
Parameter selection and store functions are verified by
individual LEDs.
