The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance (servicing) instructions in the literature accompanying the appliance. 1. [. . . ] FX to AUX3 These controls allow to mix the FX1/2 output signals with the AUX3 signal. In case you are using the AUX3 bus for monitoring purposes, you are able to add the FX signals at the desired level to the monitor mix. Experience in mixing has shown that the effect level in the monitor mix should be lower than the level in the main mix. AUX/FX SEND These rotary controls could also be called FX SEND master controls, since they are used to adjust the overall level of the effect mix that you have established using the channel FX send controls. The AUX/FX SEND controls are used to set the input levels of the corresponding FX unit, respectively and the levels of the AUX SEND outputs. Whenever the Peak LED (PK) blinks, there is the potential risk that the FX input signal is driven into clipping, making it necessary to reduce its level by turning the corresponding AUX/FX SEND control to the left, until the LED is not lit anymore. Since the AUX/FX SEND controls not only affect the signals of the FX buses but also the monitor effect level, which is sent by the FX to AUX3 control, careless changes can result in acoustical feedback. 10 of 32 EFFECT 1/2 30. FX ON These switches are used to turn the internal FX units on ­ the green LED is lit. Please keep in mind that you also can use an external foot switch to turn the FX units on. In this case the LED also shows the actual state of operation. If you want to use a foot switch, the FX ON switch has to be engaged first. The corresponding FX unit is activated and you can use the foot switch to turn the selected effect program on or off. 31. PEAK LED These indicators show if the input stages of the internal FX units or the AUX 1/" SEND signals are driven into clipping. To achieve an adequate S/N ratio, please adjust the FX units' input level as follows: Note on how to adjust the FX input signal: 1. Establish a "dry" mix ­ without effect settings ­ according to the previous descriptions. Set the AUX/FX send controls of the effect channels to their center position. Position the effect return faders of the effect channels at the ­5dB marks. Use the UP/DOWN buttons to select the desired FX program preset. Play the sound source of the desired input channel and adjust the desired amount of the FX signal, using the AUX/FX controls of this input channel. Repeat this step for all input channels that you want to include in your effect mix. Adjust the AUX/FX SEND controls, so that the Peak LED only lights frequently at highly dynamic signal peaks. Use the FX to AUX3 control to add the effect mix to the monitor mix. [. . . ] The LF-signal outputs of the crossover are connected to an external power amplifier, driving the woofer cabinets. The signal of the crossover's HF-signal outputs is fed into the PSX's internal power amplifier via the POWER AMP INPUTS. Compared to the passive configuration, the overall sound gains clarity and higher volume levels are possible, since the Hi/Mid cabinets do not have to deal with the low frequency signals. 25 of 32 SPECIFICATIONS Technical Specifications PSX Mixing desk in rated condition, Unity Gain ( MIC Gain 20 dB ), all faders position 0 dB, all pots in mid position, Master fader + 6dB, amplifier rated output power into 8 ohms, one channel driven, unless otherwise specified.
