The Rear Panel:

17.AC LINE CORD (not shown): Connect the male end of this heavy duty power cord to a properly grounded AC power outlet of the correct voltage. DO NOT attempt to defeat the ground pin of the power cord! (If your amplifier was pur- chased outside the United States, see the rear panel serial number label for voltage and current information.)

18.IMPEDANCE SWITCH: For the best performance and least strain on the amp, you MUST match the amp’s impedance to that of your speaker cabinet(s). Set the selector switch to the 8 or 16 ohm position, depending on the total impedance of your cabinets. The chart below can help you determine that impedance based on the follow- ing combinations of speakers connected in parallel.

CAB IMP.	# OF CABS	TOTAL IMP.
16 ohms	2	8 ohms
32 ohms	2	16 ohms
32 ohms	4	8 ohms

19.SPEAKER JACKS: Connect the amplifier to your speak- er cabinet(s) via these jacks, using heavy-duty speaker cables (not instrument patch cords). Use cabinets rated at 8 ohms or higher, in combinations which never create a load lower than 8 ohms. Make sure the Impedance switch (#18) is properly set. Always use the MAIN speaker jack first, then connect to the EXTENSION jack if using more

than one cabinet.

Connecting to the Insert Jack:

The front panel Insert jack (#6) lets you patch external effects into the GT-500H just prior to its power amp stage. When using Crate’s CYC6MS stereo-to-mono Y-cord, connect its 1/4” stereo plug into the amp’s Insert jack, its “send” plug into the IN jack of the effect and its “return” plug into the OUT jack of the effect.

Another method is to buy or make a stereo-to-mono Y- adapter (such as Crate’s CA11Y) and use two 1/4” signal cables to patch into the effect as shown below.
