Speaker Simulation (SS)The Tube Fex has four stereo speaker simulation curves:35 2x12 Open Simulates the frequency response of an open backed cabinet.2~ 2x12 Closed Simulates the frequency response of a closed backed cabinet.h 4x12 Cabinet Simulates the sound of four 12” speakers in a single cabinet.~3 4x12 British Simulates the frequency response of a well known British manufacturer’s guitarspeaker setup.These speaker simulation curves are convenient for both live performance and recording applications wherethe guitar is directly connected to a mixing console.Tip: Totryonly affect what goes out the balanced (direct) outputs and have full range going to your cabinetadding the following to the end of vour effects chain:. . . +FX+SS (use the stereo Effects Send outputs to go to your cabinet)Stereo Simulator (SoA transverse filter approach is used to simulate stereo separation of a mono signal. The mono signal is fedinto a comb filter and the output and input is summed in the right channel and subtracted from the left channel.The resulting output simulates stereo separation of frequency bands. Tune adjusts the distance between theseparated frequency bands. There is a LowI’ass filter which, when on, will keep the bass centered betweenthe two channels. The Depth of the stereo separation is variable from 0400%.ParametersLP The LP (LowPass) parameter is a lowpass filter which, when on, will keep the bass centeredbetween the two channels. Choose ON or OFF.TUm: The Tune parameter adjusts the distance between the separated frequency bands.Range is 100~SOOHz.Dc$d: The Depth parameter is the depth of the stereo separation. Range is O-100.The Noise Gate effect is a downward expander.Noise Gate (NG)The Peak level is determined by the input signal plus attack and decay variables which set the speed at whichthe peak can change.ParametersAtkRd.-The Atk (Attack Time) parameter is used to remove sharp attack transients. The larger this numberthe longer the attack will take to open the gate once closed. Lange O-99.The Rcl (Release Time) parameter adjusts the amount of time it takes a decaying signal to dropbelow the threshold. The larger this number the longer it will take for a decaying signal to dropbelow the threshold. Range l-99.Appendix A Individual Effects A-75
