The only signals not affected are AUX sends selected to be pre-fader. The fader offers greater than 80db of attenuation and up to 10db of boost. Normal operation is between -10 and 0. pre-fader listen--PFL Pressing this switch will include (illuminated) or exclude (not-illuminated) the input channel. see--master module p. 37 2 stereo input module module block diagram X-Four owner's manual panel 1 3 +10 Ø L p. 38 R NO R L stereo input module 2 rear panel features The stereo line-input module provides connectors for three stereo linelevel signals. see--line 2 switch. balanced left and right line-in XLR connectors These two jacks accept balanced or unbalanced +4dB line level signals. The LINE 2 switch on front-panel must be disengaged for these connectors to be active. F line-input left and right 1/4" TRS jacks These two jacks accept balanced or unbalanced line level signals. The LINE 2 switch on front panel must be engaged for these jacks to be active. line-input left and right RCA connectors These two jacks accept unbalanced line-level signals. They are active when the LINE 2 switch on front-panel is engaged and nothing is plugged into the corresponding left or right 1/4" TRS jack(s). p. 39 3 group module module block diagram X-Four owner's manual panel +10 +10 p. 40 group module 3 output eq features The X-Four output-section includes eight output-equalizers occupying the upper portions of the four GROUP sub-modules and the four MASTER submodules. By using designated assignment switches, output eq's can be fed by the six AUXES or GROUPS, the two matrix masters or left, right, and mono masters. Each eq features four bands of equalization, making them ideal for feeding on-stage or in-ear monitors. high frequency--HF 15dB boost and cut at 12kHz--shelving response. high-mid frequency--HM 15dB boost and cut. Selectable frequency range of 400Hz to 8 kHz. The response is bell-shaped with a fixed Q of 1. 5 mid frequency--MID 15dB boost and cut Selectable frequency range of 200Hz to 4kHz. The response is bell-shaped with a fixed Q of 1. 5 low-mid frequency--LM 15dB boost and cut. Selectable frequency range of 80Hz to 2kHz. The response is bell-shaped with a fixed Q of 1. 5 low frequency--LF 15dB boost and cut at 80Hz. The boost response is bell-shaped and the cut response is shelving. p. 41 3 group module module block diagram X-Four owner's manual panel +10 +10 p. 42 group module 3 output EQ features equalizer--EQ ON Equalizer is on. This switch can be used to make A/B comparisons between "flat" and eq'd signals. This switch can be used to make A/B comparisons of "flat" and EQ'd signals. + group equalization --per output channel--EQ TO GROUP This switch selects the signal path for the eq. eq to AUX MASTERS eq to GROUPS p. 43 3 group module module block diagram X-Four owner's manual panel +10 +10 legend p. 44 group module 3 matrix features The X-Four includes two MATRIX outputs. Each of these outputs can be made up of signals from the four GROUPS; the left, right and mono buses; and an external source. matrix 1­2 levels--M1, M2 These level controls are used to mix the group's signal into the corresponding matrix. post-group The GROUP fader setting has no effect on the group-to-matrix level controls 1­2. The GROUP fader is introduced into the signal path. When the group is muted, the matrix level controls 1­2 are muted as well. p. 45 3 group module module block diagram X-Four owner's manual panel +10 +10 legend p. 46 group module 3 fader reverse The AUX / GRP feature is used to swap the functions of the AUX MASTER controls and the GROUP MASTER controls and the AUX MASTER and LEFT/RIGHT MAIN controls.

If possible the power supply should be connected to a dedicated circuit. Should any other appliance on the same circuit draw enough current to overload the circuit, the breaker or fuse will trip causing loss of power to the console. The power switch on the supply front panel is also a circuit breaker; there is no power fuse. Should the supply ever shut down, or trip at start up, simply push the switch to the off position and then push on again. Note the maximum current draw specifications at left. [. . . ]
