Receiving Inspection INSPECT YOUR X-AMP FOR ANY DAMAGE which may have occurred during shipping. If any damage is found, notify the shipping company and call CARVIN immediately. SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to reship your amp, always use the original carton and packing material. This will provide the best possible protection for your unit during shipment. CARVIN and the shipping company are not liable for any damage caused by improper packing. SAVE YOUR INVOICE.
Quick Set Up If you're like most new owners, you're probably in a hurry to use your new X-Amp. Here are some brief instructions to get you started. 1) CONNECTING AC POWER • Check and change if necessary the rear AC Voltage Switch to the proper voltage. On some models a switch will not be not found, instead pull out the Fuse Holder (built into the AC cord receptacle) and turn it over to the proper voltage as seen on the holder.
turn the TREBLE and PRESENCE controls down. Use only the amount you need—these controls are very powerful. 9) FS36 FOOTSWITCH • The optional FS36 footswitch remotely controls the channel switching by depressing the "CH" button on the footswitch. Be sure that the LEAD DRIVE control is pushed in for this to work. The EFFECTS LOOP only works with the FS36. To control it, depress the "EFF 1". The REVERB is controlled by depressing "EFF 2".
X-Amp Design (technical description) (Refer to schematic diagram) Signal input to the X-Amp is by way of either the High or Lo input jacks. These are shorting type jacks with input resistor arrangement (R62 & R63) such that the LO input is attenuated 6 dB with respect to the HI input when either jack is used alone. If both jacks are used simultaneously then they each will have the same sensitivity. The input impedance at the HI jack is 2.2 Megohm (R14): the LO input impedance is 20k ohms (R62 plus R63).

IN CASE OF TROUBLE All X-Amps all fully tested with a 10 hr break-in period before they leave the factory. However, on those rare occasions when an X-Amp fails to operate properly, the problem is almost always with the vacuum tubes. Vibrations from shipping is usually the cause. The solution to fixing the problem could be as simple as replacing the defective tube.
CHANNEL SWITCHING / FOOTSWITCH PROBLEMS a) Verify that the channel switcing and reverb are working properly with the footswitch disconnected. b) If the footswitch is not working, tighten the small set screw in the XLR connector on the footswitch cable. NOTE: this is a reversed—right-hand thread). The footswitch ground makes its contact through this screw. c) If the channel switching at the amp is not working, replace the defective 4049 IC and check the R132, 22 ohms resistor.
