Controls and Functions Mono Input Channel Section The following section details each part of the twelve mono input channels. 1. SIGNAL LED - MIC/LINE preamp SIGNAL LED which, when illuminated, indicates that the signal is present at the input. 2. GAIN Control Knob - Variable GAIN control with a range of -6 to -50dB on the MIC input and +14 to -30dB on the LINE input. 3. LOW CUT Switch - LOW CUT (or high pass) filter rolls off the low frequencies from 75Hz and below at the rate of 18dB per octave. 4.
Controls and Functions 6. AUX 2 (PRE/POST) - Controls the amount of that channel’s signal that is sent to the AUX 2 Output. The signal that feeds Aux 2 is sent before, or pre, the channel Fader, so the channel Fader has no effect on the Aux 2 level. On the S4000, Aux 2 can be configured for pre or post fader send using the PRE/POST switch.
Controls and Functions Stereo Input Channel Section The S4000 feature stereo input channels for connected stereo line level devices like keyboards and drum machines, as well as the outputs from effects processors and digital guitar modelers. 15 16 15. SIGNAL LED - The SIGNAL LED which, when illuminated, indicates that a signal is present at the input. 16. GAIN Control - The preamp stage has a variable GAIN control with a range of -20 to +20dB on the stereo LINE input. 17.
Controls and Functions When the POST switch is in the down (POST) position, the signal feeding Aux 2 is sent after the fader, so the channel Fader has an effect on that level, meaning the Aux level tracks up and down with the channel Fader. This is the normal setting for using Aux 2 as an effects send, since when you set the channel louder you normally want the effect to get louder. 21.
Controls and Functions Digital Effects Section The S4000 feature built-in, 24 Bit Digital Multi-effects Processors with 100 dazzling, studio quality effects like Delay, Chorus, Flanger and lush Reverbs including Halls, Plates and Rooms. The following section describes the features control knobs and layout of the powerful on-board digital Multi-effects section. 28.
Controls and Functions Stereo Line Inputs 36. AUX 1 (Pre Fader Send) - Controls the amount of that channel’s signal that is sent to the AUX 1 Output. The signal feeding Aux 1 is sent before, or pre, the channel Fader, so the channel Fader has no effect on the Aux 1 level. The Aux 1 bus is usually used to create a separate mix for a floor monitor system. 37. AUX 2 (Pre Fader Send) - Controls the amount of that channel’s signal that is sent to the AUX 2 Output.
Controls and Functions PHONES and CD/TAPE MP3 IN Section 42. PHONES Control knob - This control adjusts the level of Headphone Output. 43. MAIN MIX 2 Control Knob - The mixer provides a second set of output connectors carrying a duplicate of the MAIN MIX signal for the purpose of feeding another speaker zone or recorder. The MAIN MIX 2 control knob is used to set the volume of the MAIN Mix 2 output. 44. Mute CH 1-12 Switch - This switch mutes input channels 1-12.
Controls and Functions Main Output Section 51. PEAK Indicators - The left and right PEAK indicators illuminate when the signal from the MAIN mix is beginning to reach a level where distortion occurs. If the PEAK lights stay on, your mix is too "hot" and you need to lower the MAIN mix volume. It is okay for the PEAK light to occasionally light, however they should go off quickly and not stay on. 51 52 52.
Controls and Functions Power Amp Section The S4000’s power amplifier section includes the PEAK limiter and Phantom Power switch, as well as LED indicators for the Protection Circuit. The PHANTOM POWER switch engages the power supply to allow you to connect condenser microphones. The PEAK LIMITER helps you keep the sound clean by using an active circuit to automatically control the system dynamics. And the Protection Circuit will help your S4000 run trouble free for years. 55.
Controls and Functions Graphic Equalizer Section 57. MONITOR EQUALIZER - This nine-band MON57 ITOR EQUALIZER allows you to contour the 58 frequency response of the AUX 1 mix bus signal. Providing a maximum of 12dB of cut/ boost for each frequency band, the Graphic EQ is also extremely useful tool for cutting the frequencies that cause annoying feedback. The frequency response is flat when the sliders are 59 60 in the center position.
Input and Output Connections The S4000 mixer has 20 mono mic/line and stereo line input channels, for connecting a variety of signal sources from microphones to line level devices such as synthesizers, drum machines and direct boxes. Channel 1-12 Mono Mic/Line Inputs The mono mic/line inputs each have a LINE level input, a MIC level input and an Insert connector for effects. A. MIC (Microphone) Input - Use these inputs to connect Low Impedance microphones and low-level signals from direct boxes.
