31、ections for foot switch The PCS-31 connection cable for the foot switch is a conversion cable connecting a stereo plug and two standard plugs. Connect the standard plugs to the foot switches. The “white” side of the standard plug is used to change JC CLEAN and LEAD of SELECT. The “red side” of the s

32、tandard plug is used to switch EFX on and off. TIP and RING of the stereo (TRS) plugs of the PCS-31 correspond to SELECT and EFX, respectively. 2. Setting up of the panel Set the LEAD CH rotary switch to “ACOUSTIC”, and all other knobs to “0” or “off”. Undepress the SELECT button to JC CLEAN (to gre

41、LECT switching (white side) during version display to turn off the LEDs and start automatic checks. The LEDs come on in the order of green, red of SELECT and red of EFX during the checks. If all the checks are completed and the results are OK, all LEDs blink. If the results are NG (no good, fail), o

42、nly the EFX LED blinks. The automatic checks take approximately 5 - 6 seconds. If the check results are OK, press the foot switch for SELECT switching (white side) to proceed to the next check. If the results are NG, the next check cannot be started. 3. Switch check: When the switch check starts, al

43、l LEDs go out. 1. SELECT switch operation check Press the SELECT button. If the check results are OK, both of the green and red LEDs of SELECT come on. If the check results are NG, none of the LEDs come on. The next check cannot be started, either. 2. Operation check for “AMP TYPE switching” of LEAD

44、 rotary switch Shift the switch slowly in the following order to check if the switch setting is read correctly. At this time, check if the green and red LEDs of SELECT come on alternately as follows. ACOUSTIC (green, red) BLACK PANEL (green) BRIT COMBO (red) TWEED (green) CLASSIC STACK (red) METAL S

If the check results are NG, the green and red LEDs do not come on simultaneously.

46、The next check cannot be started, either. If the switch knob is shifted too fast, the green and red LEDs blink. In this case, repeat the operation slowly to allow the switch settings to be read at all positions. 3. Jack switch (foot switch terminal EFX, RECORDING OUT/PHONES terminal) check a. Foot s
