[. . . ] In the absence of such purchase receipt, the warranty period shall be one (1) year from the date of manufacture. This warranty shall be invalid if the product is damaged as a result of defacement, misuse, abuse, neglect, accident, destruction or alteration of the serial number, improper electrical voltages or currents, repair, alteration or maintenance by any person or party other than our own service facility or an authorized Service Center, or any use violative of instructions furnished by us. This one-year warranty is in lieu of all expressed warranties, obligations or liabilities. [. . . ] To understand it better please read and refer to the rest of this manual. OPERATION The LED display on MP80 EX shows the MIDI program number in a octal (count-by-8) bank preset format. The first digit shows the bank number (0 - 7. . ) and will go through all the digits then start over as the UP or DOWN switches are pressed. The first number is 0, then up to 9, then it jumps to 2 with both decimals on and counts up to 7 with both decimals on (7. . ). If the UP is pressed again it will go back to 0. The exact MIDI program # can be found by the formula (bank #+1) X (patch #+1)=MIDI program #. The MP80 EX has two modes of operation set by dip switch number 6, switch 6 OFF=128 mode, ON=80 mode. The 80 mode has only 10 banks and may be easier to use if you only need access to 80 presets. The UP and DOWN buttons select the desired bank (0 9 or 0 to 7. . ) but MIDI information is only sent when a patch button (0 through 7) is pressed. SELECTING A PRESET Buttons on the pedal are labeled UP and DOWN and 0 - 7. Pressing a numbered button causes a MIDI program change message to be sent. The selected preset number is displayed in the window right hand digit. Pressing the UP or DOWN buttons moves you into the next higher or lower group of 8 presets. The display will show the new bank selected in the left hand digit. INSTALLATION Apply power 7 to 15 volts AC or DC to the power jack on the rear of the MP80 EX or it may be phantom powered through the MIDI jack. While there is no standard for MIDI phantom power there is a convention of pin 1 as ground and pin 3 as hot, the MP80 EX may be phantom powered by 7 to 25 VDC @ 50 ma. [. . . ] With switch 6 off the banks go from 0 to 9 for 10 banks of 8 or a total of 80 program changes. SETTING THE MIDI CHANNEL NUMBER The MIDI channel is set with DIP switches 1-4 on the rear of the MP80 EX in binary coding, all off=ch 1 all on=ch 16.
