1. PATHFINDER S MEMORY PathFinder has very good memory It remembers all your programming the number of banks you use and the last mode used standard or up down All this information is stored in non volatile memory EEPROM meaning that the next time you turn PathFinder on you won t have to customize everything again No battery is necessary to keep this information RESET PROCEDURE At any time you may wish to restore PathFinder to its factory settings Also in rare occasions data stored in non volatile memories may get corrupted and cause strange behaviors In both situations the easiest procedure is resetting PathFinder to its original state following these steps 1 Unplug the power chord 2 Hold the left pedal P1 pressed and reconnect the power chord You can release P1 now You ll see leds and display being turned on The pedal will perform a self programming of its original EEPROM contents 3 If you see E blinking at the display it means some error occurred Try repeating the procedure If fails persist contact GNI or it s representa tive 4 If you don t see E blinking PathFinder was successfully reset to factory s standard Remove the power chord and connect it again to start using the pedal normally If strange behavior persists contact GNlorit s representative ALTERNATIVE USES FOR PATHFINDER PathFinder as an instrument or amplifier selector PathFinder has not been originally develo2. In the example signal passing through line A is sent by S A to a drive pedal and returns to PathFinder into R A Note that you can have as many pedals as you wish in each line Line C is an example of that signal is sent from S C to a chorus pedal then to a reverb pedal and returns to PathFinder into R C Banks programs Each program bank determines which lines are turned on and off In our example bank number 3 is selected and represents lines A and D enabled You can create up to 9 programs combining the lines as you wish The only restriction is the sequence always from Ato D How to set up the banks will be explained ahead Note that all lines enabled and all lines disabled are valid programs the last is alternative bypass method Bypass on off When PathFinder is off signal bypasses all lines and goes from input to output through a series of internal buffers When it s turned on signal passes in sequence through all lines signaled active by the correspond ing leds A bank programmed as all lines disabled has the same effect of bypassing alllines You can have other pedals before input and or after output and use them independently Two modes button B2 You can use PathFinder in two distinct ways normal and up down modes Normal Mode lets the user turn the unit
3. GNI MUSIC PATHFINDER S USER S MANUAL INTRODUCTION Thank you and congratulations on your choice for GNI Music s products Lots of work from engineers and professional musicians were spent in order to create really high end pedals These sections provide important information concerning the proper operation of our pedals Please read in order to feel assured you re ready to explore all available resources Please keep this book for future reference For more information and hints check www gnimusic com WHAT IS SPECIAL IN LAI PATHFINDER Musicians usually need several effects to create rich performances They can either purchase a single digital unit which offers several effects and are easy to operate or buy traditional individual effect pedals The second choice is usually considered more professional It allows the musician to fully customize it s set and take advantage of specialized analog circuitry avoiding digitally processed signals which become quite artificial sometimes The main disadvantage of pedalboards mounted with traditional pedals is that they are hard to use in some situations It s impossible for example to turn one effect on and another off at the same time The solution is the use of Line Selectors Using one allows the musician to connect several pedals in loops instead of a simple serial connection and then turn entire loops on and off simultaneously Most line selectors today are bi

5. g pieces of equipment powerful but expensive and unpractical GNI s PathFinder is the first compact line selector to offer a real solution intelligent operation and great value Its very important to note that PathFinder has a microcontroller that switches several analog paths inside it It means that there is no digital processing From your signal s perspective all the way from input to output is pure analog circuitry designed to cause no losses or distortion POWERING UP You need to power the LS1 with a 9v DC power supply through the jack in the back Since 151 consumes more current than GNI s other pedals adaptors 500 mA or bigger are recommended Also due to its current it can t be used with 9V batteries The plastic battery cover on the bottom of the unit serves only to close it There is no connector inside Please pay attention to the following specifications when purchasing a power supplyt Not complying with them may cause permanent damage tothe LS1 and void the warranty 9V DC regulated adaptor soc 7 O Polarity according to the figure y WARNING Unregulated or switched mode supplies may 500 mA recommended cause noise Wrong tension values or reversed polarity may cause permanent damage to the pedal not covered by warranty CABLING To take advantage of LS1 you must cable it properly You can group pedals as you wish using 4 loops Banks must also be progr
6. gth and levels in use gt To use amps D turn PathFinder on and choose a channel where the respective lines are enabled If you followed instructions correctly you can use all amplifiers at the same time gt Since amplifier D is connected directly to the output it will be always on If you don t want it you can simply leave main output disconnected TROUBLESHOOTING All pedals are tested before leaving GNI s facility If you are finding difficulties please pay attention to the following details Most small problems are easy to solve with a simple checklist Try to isolate the problem does the bypassed signal function correctly Is the problem in any specific line PathFinder requires many cables Pay attention to broken ones Check if you haven t missconnected send and return jacks Try reseting PathFinder If using DC adaptor be sure it respects our specs Reversed polarity wrong tension etc may damage the circuitry and compromise warranty Check volume levels Keep your unit away from other electrical devices TVs and other home appliances can cause interference and noise Don t play very close to the amplifier or directly facing it in order to avoid feedback noise If you ve carefully checked your setup and problems persist please contact our technical representative at your country for further support and warranty If you can t find our representative s informatio

8. me For example when you use guitar B line B signals coming from the main input jack guitar C and line A guitar A will be lost PathFinder as AMPLIFIER selector Amplifiers are signal sinks You can send the signal coming out from a line s send jack directly to the amplifier However you need to send this same signal back into the line s return jack The following example explains how to to it Example connecting amp C in loop C amp D in loop D and amp E inthe main output jack You need to split signals in the send jacks You can use for example a splitter Y cable 1 male to 2 female 1 4 adaptor all mono Insert the splitter in line C s send jack S C Now you have 2 copies of the signal coming out from line Connect one of the splitter s female jacks to R C using a standard cable of appropriate length Now PathFinder can find it s own signal previously split returning to it Connect the other female jack to amplifier Repeat the procedure to line D split the signal in S D cable it back to and connect the other female jack to amplifier D Connect amplifier E to PathFinder s main output jack Operation and restrictions gt Whenever you bypass signal will not pass through lines and D so amps connected to those lines should be silent However some residual audio might be audible depending on the signal s characteristics stren
