Make sure that you have the correct mains voltage. Only operate with the unit with the mains voltage marked on the rear panel. 2. Ensure that no objects (in particular metal objects) are Inserted into the unit. This could cause severe electric shock or give rise to malfunction. 3. If the unit is suddenly moved from a cold place to a warm place, e.g. transporting from outside into a heated room, condensation will occur. In this case you should not switch the unit on until it has warmed up to room temperature. 4. In the event of water or any other fluid being accidentally spilt on the unit, switch the unit off immediately and send it to a qualified service workshop for inspection. 5. Always ensure that the unit is well ventilated and never exposed to direct sunlight. 6. Do not use sprays to clean the unit as these may cause damage to it and could suddenly ignite. PSX 1250 - General Overview PSX 1250 - General Overview • 12 Input channels = 8 x Mic / Line + 4 Mic / Line Stereo • 4-band equalizer In each input channel • Two separate digital 16 bit stereo effect units • 1 digital 16 bit stereo effect unit with 6 reverb 8 delay programs and 2 special effects • 1 digital 16 bit stereo effect unit with 16 delay, flanging, chorus and doubling programs • 48 V Phantom Power • 2 effect paths • 1 AUX/Monitor path with 3-band equalizer and separate PCA processor power amp • Controllable Line In and Line Out path • Controllable Tape Record and Tape Playback path • Big 3-way LED Level Meter • 2 x 250 Watts (RMS/4 Ohms) PCA processor power amplifiers for master • 1 x 200 Watts (RMS/2 Ohms) PCA processor power amplifier for monitor The mixer of the PSX compact pov/er mixers is equipped with a wide range of features. The stereo input channels allow the connection of stereo program sources like keyboards, drum machines, tape recorders and additional mixing desks. Thus a lot more sound sources can be connected than with conventional power mixers. The stereo input channels can also be used as regular mic input channels. All mic inputs are electronically balanced and equipped with XLR sockets. 48 volt Phantom power can be switched to the mic sockets. The effect section is equipped with 2 digital 16 bit stereo reverb/delay/ special effect modules. One effect unit generates different, extremely natural sounding stereo reverb programs, special stereo programs which combine the reverb programs with additional echoes, and a stereo chorus program especially structured for vocals, brass and woodwinds. In addition 8 different delay and echo programs with excellent quality are available from the ARS 10 DSP effects board. The number of echo repeats is front-panel controllable. The other digital effect unit generates 16 different delay, flanging, chorus and doubling programs. The master section is equipped very comprehensively with separate control functions, e.g. for tape playback and record, connection for an additional external stereo effect unit, separately controllable AUX/LINE output/input and big LED level meter for the power amplifiers. ThePCAprocessorpowerampllflersare designed in advanced Hi-PowerMOS technology. The frequency and phase response of the loudspeaker cabinets connected is linearized in the low-frequency region with a 2nd order shelving eq. The comer frequencies of the 2nd order shelving eq have been designed to match with the characteristics of modern high-efficiency loudspeaker cabinets. A built-in fast acting limiter prevents excessive overdrive. The power...
