1. An amplifier is connected to Loops in Chain s output jack and the other ona particular loop in this case loop 4 Each presets have designated the effects and control lines which are to be used with each amplifier You can set up presets that use the effects attached in ports 5 6 and 7 for both amplifiers and effects connected to ports 1 2 and 3 will only act on the left amplifier If we shift everything to connect right amplifier into port 1 all effects will be accessible to both amplifiers The example gives us an idea of Loops in Chain s potential to build quite sophisticated setups Even a preset can be configured to operate both amplifiers at the same time providing the measures necessary to avoid ground loops This example shows how using a loop configured as control line it bridges both amplifier inputs to operate them simultaneously In this way you can have presets for A presets for B and presets for A and B together INTRODUCTION CONNECTIONS OPTIONAL ADD ONS SPECIFICATIONS OPERATION POWER PANEL PRESETS MODE INSTANT ACCESS MODE BUFFER MUTER CONTROL LINES CABLES SETUP EXAMPLES EXAMPLE 1 AMPLIFIER WITH EFFECTS LOOP EXAMPLE 2 TWO AMPLIFIERS Amb RWW WN2. Reset button turns off everything to stay in Truebypass In the effect selection mode each of the 8 buttons selects a loop If any loop is configured as control line it will operate the line In this mode loops are activated and deactivated by pressing and can build up those who are active The reset button turns off all active effects and control lines with a stomp Optional output Buffer Integrates a transparent buffer for the purpose to connect long cables to the amplifier without affecting the signal It can also be disabled if not required Muter It includes an automatic circuit that mutes or attenuates the signal during relays switching to reduce plop noise in the amplifier You can disable it from the panel Anti Bounce circuit for safe buttons operation Pull down resistors integrated in each loop Avoids plop noise produced by some effects when activated in the chain Aluminum cabinet with 2 mm thickness Connections Instrument input 1 4 mono jack 6 35mm Output to amplifier 4 mono jack 6 35mm Power jack 9 Volts DC 2 1mm pin center negative Optional add ons Loop Cables Y cable Insert cable for each stompbox Amplifier Effects loop cable Single Control line cable Double Control line cable 9V 1A Regulated power supply with center negative plug Specifications Power Supply 9Vdc Current draw up to 450mA with all loops active Dimensions 450x110x40mm 60mm tall including foot buttons Weight
3. ports it is likely that that port has been configured as control line To activate a control line the Loops in Chain closes a contact linking two cable wires To disable the line that contact is open To avoid ground loops this contact is made between tip and ring terminals in Loops in chain jacks Cables Y Cable the cable required for each loop is a shielded stereo cable that has a stereo plug on one end and two 1 4 mono plugs the other Stereo plug is plugged into Loops in Chain s loop jack and mono plugs are for effect s In and Out jacks or chosen effects chain Amplifier Effects loop cable is a shielded stereo cable that has a 1 4 stereo plug on one end and two 1 4 mono plugs on the other Stereo plug is plugged into Loops in Chain designated loop s jack and mono plugs are for amp s Input and EFX Send jacks Single control line cable is a mono cable that has a 1 4 stereo plug one and a mono plug on the other The stereo plug is plugged into the designated port on the Loops in Chain and the mono plugs to the footswitch jack on the amplifier Double control line cable is a stereo cable that has two 1 4 stereo plugs one end and a stereo plug on the other The first stereo plugs are plugged into the designated ports on the Loops in Chain and the single stereo plugs to the footswitch jack on the amplifier Setup examples Example 1 Amplifier with effects loop In the following
4. 1225 gr Operation Power The unit has its own 9V power supply optional but is feasible to use an output of a multiple power supply if so desired The unit uses center negative plug In any case it is recommended to use a same wall power outlet connector for all effects and the amplifier to prevent ground loops that give rise to hum or buzz in amplifier speakers INPUT POWER m gt INSTANT ACCESS RESET Presets Mode In preset mode each button activates a preset previously set using the dipswitches which lie at the bottom of the unit Each of the 8 dipswitches boasts 10 microkeys that correspond to each of the 10 loops control lines When you select the On position on each of the keys you are setting it to activate corresponding effect control line every time you select that patch or preset In this way the 8 dipswitches make up a bank of 8 configurable presets The possible combinations of each dip switch are 1024 which multiplied by 8 gives us the incredible amount of 8192 combinations In this mode the green LEDs indicate the patch or chosen preset and the blue LEDs indicate for that patch which loops control lines are active This mode is active when the Instant Access LED is off If the LED is on you must step on the Instant Access button to switch to Presets mode Instant Access Mode In Instant Access mode you can have direct access to the first 8 loops with each one of the 8 swi
5. ER NORMAL MUTER NORMAL 1 Buffer Integrates an output buffer that can be disabled or enabled at any time from the panel lever It is a unity gain buffer so it keeps same level and tone it only lowers the output impedance of the unit This allows the guitar to only see the input cable and not the output cable thus lowering the capacitive load imposed on the microphones and keeping guitars tone crystal clear You can easily check if this changes the tone by changing the position of the lever while playing in TrueByPass State stepping on reset Muter This circuit is triggered each time that you press a pedal and produces a very short time attenuation in the output signal to avoid relay s switching plop spreading towards the amplifier These plops can occur for many reasons In some pedals there are internal electrolyte capacitors which are loaded at activating them and this produces a transient load resulting in a powerful click or plop in amplifier speakers To avoid this regardless of Muter circuit Loops in Chain has a resistors on each loop that keep these capacitors loaded to prevent that transient Noisy switching stompboxes can be identified using the Instant Access mode activating one by one to diagnose this issue In any case circuit helps to reduce the level of the plop and does not alter signal tone It is implemented with a FET that is completely cut off in the normal state and produces
6. JAKE AMPS Loops in Chain RESET Introduction The product is a switcher that allows you to organize a very populated pedalboard and facilitate effect changes rapidly in a live performance without so much tap dancing It also allows more sophisticated applications so far only available on MIDI equipment This unit provides many possibilities without the need for complex configurations and at a very affordable cost Allows the use of any effect pedal wether it is TrueByPass or not and the Loops in Chain turns it automatically into TrueByPass It has the following features 10 effect loops any of which can be internally configured as amplifier control lines or of any other device 8 footswitches to select presets or patches 1 reset button to Truebypass whole unit 1 button which allows you to change the mode of operation 8 green LEDs indicating the preset or active loop 10 blue LEDs that indicate active loops control lines 1 red LED indicates that the unit is powered 1 red LED indicates that the active mode is Instant Access 8 dipswitches each with 10 microkeys to set presets or patches set of effects or control lines which are activated to select the patch Allows to have 8 configured presets and access to them from a single stomp 2 modes of operation patch selection Presets or effect selection Instant Access Patch selection mode changes the active patch to the new chosen with a single stomp
7. a short enough less than 10 ms cut to mask only the plop Control Lines All Loops in Chain ports can be configured as loops or control lines For this it s necessary to open the unit since this is done via internal jumpers J14 to J23 located on the analog board near each loop connection jack There are two jumpers for each loop if the jumpers are placed vertically that port is set to loop and on the other hand if they are placed horizontally that port is configured as control line 0 j a Control To open the unit you only need to remove the 4 screws of the top half of the cabinet and open carefully both halves taking particular care that both are linked by internal wiring Then you need to remove all the jack nuts and the three analog board fixing screws to remove the board and set the jumpers Loop The control lines are used to modify by means of a footswitch any feature of an amplifier which can be channel power Reverb etc With Loops in Chain there no need for an amp FSW Loops in Chain can operate that line every time the patch says so or in Instant Access mode if the line was set within the first 8 ports Factory setting is such that ports 1 to 8 are configured as loops and ports 9 and 10 are configured as control lines except customer express request at purchase time If an effect is not activated when you select it in a particular port and it works if you plug it in other
8. diagram you can see how to make a connection where some effects are at amplifier s input and some are in amplifier s effects loop Loop 6 is amplifier s preamp and should be always on If you turn it off you can enter directly to amplifier s power stage EFX s loop return bypassing amplifiers preamp Effects Loop In Loop send Loop return Example 2 Two Amplifiers In the following diagram you can see how to make a connection where two amplifiers are used Loops in Chain allows to switch from an amplifier to another by simply stepping on the appropriate patch and set the effects chain accordingly at the same time Two Amplifiers
9. tches Access to loops 9 and 10 is not available in this mode because there are only 8 available buttons This mode is aimed at improvisation allowing you to freely combine the eight effects assigned to these loops activating and deactivating each one individually and clearing all the loops from the Reset with a single stomp If one of those loops was configured as control line selecting it will toggle that line behaving as a footswitch In this mode dipswitches settings doesn t matter Green and blue LEDs will match in this mode since each button acts ona single loop control line You can pass from mode to the other at any time by simply stepping on the mode Presets Instant Access button In Presets mode the last selected preset is retained in memory even when you change mode In Instant Access mode changing mode will reset the selection Whatever is the state of loops control lines stepping on the reset key turns them all off both in the Instant Access mode and Preset mode leaving the audio line in TrueBypass Powered off unit is also in TrueBypass Effects order of sequence is set when it was decided in what loop to connect each one and it is fixed Although there isn t a prestablished effects order it is recommended to always put delay and modulation effects after overdrive and distortion effects Also if the amplifier has an effects loop it is recommended to put modulation and delay effects in this loop OUTPUT 4 BUFF
