Rear Panel | Crate Amplifiers GTX3500H instruction

The Rear Panel:

28.LINE OUT: When using an external effects processor, connect this jack to the input of the effect by means of a shielded signal cable. This jack also doubles as a source for a post-EQ, preamp signal to send your signal to a mixing board, recorder, powered monitor or external amplifier.

29.LINE IN: When using an external effects processor, connect this jack to the output of the effect by means of a shielded signal cable. This jack also doubles as a direct connection to the power amp, bypassing the input and preamp stages. This is useful for “slaving” a pair of ampli- fiers together.

30.SPEAKERS: Use these jacks to connect the amplifier to your speaker cabinet(s) using speaker cables with mono 1/4” plugs. These jacks are wired in parallel. Make sure that the com- bined impedance of your speakers is equal to or greater than 2 ohms! Use the chart below to help determine parallel loads. If in doubt, ask your dealer.

CAB IMP	# CABS TOTAL IMP		CAB IMP	# CABS	TOTAL IMP
4 ohms	2	2 ohms	16 ohms	2	8 ohms
8 ohms	2	4 ohms	16 ohms	4	4 ohms
8 ohms	4	2 ohms	16 ohms	8	2 ohms

31.FOOTSWITCH: Use this jack to connect the footswitch cable (5-conductor midi cable) to the four-button footswitch (supplied). This allows you to remotely switch between the channels, set tap tempos, save new presets, and access a second set of DSP presets. (See page 9 for addi- tional information.)

32.FUSE: The fuse protects the amplifier from damages caused by a faulty AC power source and/or other problems. If the fuse fails, replace it ONLY with the same size and type. If fuses continue to fail, check the AC source – if the source is okay, contact your Crate dealer for service information.

33.AC LINE CORD (not shown): This grounded power cord is to be plugged into a grounded power outlet, wired to current electrical codes and compatible with the voltage, power, and frequency require- ments stated on the rear panel. Do not attempt to defeat the safety ground connection.
