User manual ELECTRO-VOICE 619KK DATASHEET

[. . . ] Do not block any of the ventilation openings. Install in accordance with the manufactures instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat. Only use attachments/accessories specified by the manufacturer. [. . . ] The preset 0 is a slap back echo which is mainly used for service and testing of the effects section and it doesn't appear on the list at the panel. The FOOT SWITCH connector is provided to allow the connection of a foot switch pedal to remote control the FX units' EFFECT ON/OFF function. If your foot switch features a LED ­ like the EV FOOT SWITCH does ­ this indicator will light when the effect is activated.

AUX1/2 SEND These jacks are meant for the connection of external FX units, providing the signal mixes that you have established for the AUX/FX buses ­ the identical mixes which are fed to the internal FX1/2 units. The output level is controlled using the corresponding AUX/FX SEND controls. The external devices' output signals can be send back to the PSX via the stereo return bus or by using stereo input channels. The AUX1/2 sends are designed with Ground Sensing technology to prevent the induction of external noise, even when longer cables are used. 26. DISPLAY The actual selected effect number is displayed. 27. UP/DOWN buttons The UP/DOWN buttons are used to select the effect presets. Keeping a button pressed constantly lets you step quickly through the program numbers. 28. FX to AUX3 These controls allow to mix the FX1/2 output signals with the AUX3 signal. In case you are using a different effect setting for the second FX unit, you have to repeat the step 2 - 8, respectively. Pay some attention to the peak indicators when operating your PSX to quickly interact when the signal levels exceed the normal range and enter clipping. 32. EFFECT RETURN These stereo faders are used to determine the effect amount of the main mix. In case you have to set these faders at a position above the +5dB mark, please check if the FX units input signals are adjusted properly. Otherwise use the AUX/FX SEND controls to increase the input levels. 11 of 32 AUX 3 Typically, the AUX3 channel is used as monitor bus. Depending on the setting of the AUX3 POST switch, it is also possible to configure the bus for the connection of an additional, external FX unit. 33. AUX3 SEND This output is meant for the connection of an external FX unit, a power amplifier or active stage monitor speaker systems, when the AUX3 bus is used for monitoring purposes. Using the AUX3 fader, the output level can be adjusted over a wide range up to +20dBu. The AUX3 send is designed with Ground Sensing technology to prevent the induction of external noise, even when long cables are used. 34. FEEDBACK FILTER The feedback filter is a very narrow band notch filter which is only active over a range that is extremely susceptible to acoustical feedback. The frequency band is set using the corresponding rotary control. [. . . ] In other words: the internal power amplifier is capable of driving a maximum of six 8 ohm speaker models. The following diagram shows how the speakers have to be connected. 6. Active stereo 2-way configuration: In this example the internal power amplifier of the PSX is used to drive the Hi/Mid cabinets. An active cross-over is connected to the MAIN OUTPUTS or the EQ OUTPUTS which carry the full-range signals. [. . . ]
