manual abstract
The various programs make for prime simulation of the original cabinets on which it was based. All the originals’ typical properties such as different frequency responses, rotor speeds, coloration, start-up and decay times have all been determinated via precise measuring techniques and subjected to psycho-acoustic analysis. In the Fx 70 the 24 bit signal processor ARS-10 calculates the identical algorithms, thus providing perfect simulation of the original sound in stereo. A room simulation can be allocated to any of the programs which calculates the reflections of the rotating loudspeaker depending on the room type and size and adds the effect. This procedure is significantly more accurate and sounds a lot more natural than reverberating the effect via a random echo program. Preferential room simulations have been allocated to each program. These can, however, be changed. All function keys have status LED’s which signalize the current operating mode quickly and clearly. A special display indicates the rotor speeds. The parameters are edited via a rotary encoder, the respective values of the selected parameters being indicated with a 2-digit display. Alterations of the parameters can be stored under one of three program memory places. It goes without saying that remote control of the Fx 70 is also possible via MIDI. The unit is thus equipped with IN-OUT-THRU sockets for integration into a MIDI system. The power supply of the Fx 70 adapts automatically to mains voltages of 90 - 250 V (50-60 Hz). This user’s manual provides a wealth of information about the Fx 70. Please read it through carefully and we guarantee you immense pleasure with your new Digital Organ Cabinet Simulator Fx 70 from Electro Voice. IMPORTANT NOTES ATTENTION: This unit must be protected from damp because of fire risk and the possibility of electric shocks. 1. Make sure that nothing, especially no metal objects, are inserted into the device. This could result in a severe electric shock or malfunction. 2. If the unit is subjected to extreme fluctuations of temperature, e.g. on being transported from outside to a heated room, condensation can form. The unit should not be used until it has reached room temperature. 3. If water or any other liquid is spilt on to the unit accidentally, the unit should be switched off immediately and taken to a servicing facility to be checked. 4. Make sure that the unit is always well ventilated and never exposed to direct sunlight. 5. Do not use sprays to clean the unit as they have a detrimental effect on the unit and could ignite suddenly. V CONNECTIONS AND CONTROLS 2. CONNECTIONS AND CONTROLS 1 INPUT CONTROL This input control serves to alter the level of the input signal to achieve optimum modulation of the Fx 70 (0 dB on the level indicator). (Also see 17 HI/LO). 2 OUTPUT CONTROL The output control serves to change the output level of the Fx 70 to drive subsequent appliances with the optimum level. 3 LEVEL INDICATOR This serves for level control of the input signal. The optimum setting is 0 dB. A further feature is the Peak/Hold function which facilitates levelling. 4.1 EFFECT ON switches between the original signal (LED off: Input > Output) and Effect signal (LED On: Input > Effect > Output). 4.2 PROG 1, PROG 2, PROG 3 trip each other and select one of the three cabinet simulations. Each program uses different parameter values (ROTOR- SPEED, BALANCE, various rooms, distortion,) and different sound settings (Equalizer). These programs can be stored with altered parameters. 4.3 PARAMETERS and MIDI The keys Distortion, Room, Rotor-Balance, Rotor-Speed Bass, Rotor-Speed Treble and Midi trip each other (respective Status LED lights up) and select the access of the rotary encoder (9) with Display (5) to the respective function. 4.4 STORE This key serves to store the current setting on one of the three program memory places. Pressing the key a little longer time deletes the user programs and loads the factory presets (factory programs) on to all three program memory places. 5 UNIVERSAL DISPLAY This two-digit display has different meanings, depending on the function selected (Status LED). If MIDI has been selected, this is shown on the display, parameter value display, MIDI received, option numbers and values. The display goes off after 10 seconds. The display is turned on either by pressing or turning the rotary encoder (9) or by pressing one of the keys (4.3). 6 ROTOR DISPLAY This display allows a visual check of the bass rotor of an organ cabinet. 7 ROTOR DISPLAY This display allows a visual check of the treble rotor of an organ cabinet. 8 STOP, SLOW, FAST This switches the rotor speed for treble and bass cabinets into one of the three steps. 9 ROTARY ENCODER WITH KEY The meaning of this key depends on the function selected (Status LED). If MIDI has been selected, the MIDI channel is altered, parameter value control, option numbers and value control. Pressing and t...
