1. Handling Protect the controls from damage during transit Use adequate padding if you need to ship the unit To avoid injury to yourself or damage to the equipment take care when lifting moving or carrying the unit Servicing Refer servicing to qualified technical personnel only Installation Install the unit in accordance with the instructions printed in the user guide OVERVIEW The ART COOLSwitchPro A B Y Switch with Isolation is a handy foot operated box that lets you switch an instrument signal guitar bass or keyboard to either of two amplifiers or amp channels A or B The Y function sends the input signal to both the A and B outputs in parallel Switch selectable features on the B channel add versatility to the basic switching functions A high quality audio transformer can be switched in to provide isolation between the input and output signals This helps reduce the danger of shock when the amplifiers are at a different potential Also this isolation along with a ground lift function helps to eliminate the hum caused by ground loops A phase reverse function lets you make sure both amps are in phase The ART COOLSwitchPro is completely passive with true bypass and is housed in a rugged stable case with industrial grade footswitches spaced for easy operation It will provide many years of reliable service whether on stage or in the studio Features e Sends your signal to either of two amps or both with foot c2. OUTPUT A and the OUTPUT B jacks the Y function or to just one of the jacks which one is selected by the A B switch A B Pushing this footswitch alternately connects the INPUT jack to either the OUTPUT A or the OUTPUT B jack assuming the Y function is disabled ROCKER SWITCHES front The functions controlled by these switches operate on the OUTPUT B jack TRANSFORMER ISOLATE This switch allows you to insert the audio isolation transformer between the INPUT and OUTPUT B jacks In the DIRECT position the transformer is bypassed In the ISOLATE position the transformer is inserted PHASE This switch allows you to invert the phase of the signal to the OUTPUT B jack This function is only available when the TRANSFORMER ISOLATE switch is in the ISOLATE position When the PHASE switch is in the 0 position the phase is not affected In the 180 position the phase is inverted GROUND LIFT This switch allows you to break the OUTPUT B ground connection from directly connecting to the other ground connections In the GND position OUTPUT B s ground is connected In the LIFT position the direct connection is broken and there is only an AC signal path to ground APPLICATION The COOLSwitchPro is a simple product You might not think there would be much to say about how to use it but it turns out there s quite a bit we d like to say First let s talk about safety The COOLSwitchPro doesn t plug into an AC outlet but b
3. you paid attention to the safety warnings above connect your amplifiers to AC power 8 No smoke or sparks Good Now turn on the amps and turn up the volume controls slightly While strumming your guitar or otherwise creating an input signal verify that you get sound from both amps by toggling the A B footswitch Toggle the Y footswitch and verify that the sound comes from both amps or just one With sound from both amps now s a good time to listen for hum If you hear any try switching the GROUND LIFT switch in the front to the LIFT position If you still hear hum try switching the TRANSFORMER ISOLATE switch to the ISOLATE position For reducing hum always try the ground lift first then use the transformer for isolation only if necessary to minimize the effect the COOLSwitchPro has on your signal Next let s check that your amps are in phase or in other words that the speakers move in the same direction when playing the same signal As you might guess the PHASE switch is what we ll use to fix phase problems However note that this switch only works when the transformer is switched in TRANSFORMER ISOLATE switch in the ISOLATE position Set up your amps side by side and set them for equal volume Make sure the Y footswitch is toggled so that sound comes from both amps While strumming your guitar lower frequencies or bass notes work best try switching the PHASE switch back and forth One position should yield sound that is fu

6. OOLSwitchPro Passive vs Active We ve mentioned that the COOLSwitchPro is a passive device This has certain benefits like being able to disregard whether a jack is an input or an output as we talked about above It also means that no power is required However there can be downsides Some guitar pickups are relatively high impedance signal sources A passive device can load them down This lowers the signal level and can affect the frequency response You may notice a slight loss of higher 10 frequencies with some guitar pickups when using the COOLSwitchPro especially with the phase reversed There are several things you can do to minimize these effects Try adjusting your amp s volume and tone controls to compensate Keep your guitar s level controls all the way up so that the control s impedance doesn t add to the pickup impedance Try using a preamp or any active effect pedal between your guitar and the COOLSwitchPro Finally if possible try using a different pickup BLOCK DIAGRAM Foot Switches THRU Rocker Switches gt Transformer 11 WARRANTY INFORMATION Limited Warranty USA only Applied Research and Technology will provide warranty and service for this unit in accordance with the following warrants Applied Research and Technology ART warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials f
7. ecause one of its main applications is to connect to two power amplifiers that do plug into AC the possibility exists for dangerous voltages to exist especially if the amps are not properly grounded Make sure your amps are equipped with the proper plugs incorporating safety grounds and that you re using equipment approved by recognized safety agencies UL CSA etc Plugging all your equipment into the same circuit e g by using a single power strip can help reduce the danger of shocks Don t use an amp with a two pronged plug or defeat the ground function of a three pronged plug by using a cheater adapter unless you really know what you re doing are feeling lucky or don t mind going out in a blaze of glory You ve been warned Now let s talk about actually using this thing Before making any connections make sure your amps are unplugged with their power switches off and their volume controls turned all the way down Now connect your guitar or other instrument to the INPUT jack of the COOLSwitchPro using a cable with 1 4 inch phone plugs on each end hereafter referred to as a guitar cable Use guitar cables to connect the COOLSwitchPro s OUTPUT A jack to your main amplifier and OUTPUT B jack to your alternate amp All rocker switch functions operate on the signal going to the OUTPUT B jack For now make sure all rocker switches are switched to the left and in their normal or inactive position DIRECT 0 and GND Next assuming
8. ller more centered and with more defined bass a sign that the amps are in phase The other position should sound weaker and more hollow and unfocused indicating the amps are out of phase Use the setting you prefer you may like hollow weak sound That s all you really need to know to use your COOLSwitchPro However here s a few more things to think about Other Uses Connect your electronic tuner to the THRU jack for tuning on the fly Or if you prefer connect your tuner to the OUTPUT B jack instead of using this jack for a second amp to provide silent tuning The A B footswitch will act as a mute switch sending your guitar signal to the tuner instead of to your amp Push the footswitch again and you re back in business The COOLSwitchPro can be used to switch between two amp channels as easily as it can switch between two separate amps Or you can turn things around and switch two different guitars or guitar and keyboard or two different keyboards or you get the idea between one amp or amp channel Since the COOLSwitchPro is completely passive the normal rules of keeping your inputs and outputs straight don t apply The COOLSwitchPro would normally be the last pedal in your signal chain before the amps but that doesn t mean you can t change things up a bit and put some pedals after it For example you might have some effects that go with one amp but not the other Play around break the rules You won t hurt the C
