VTX350H Three-Channel Guitar Amplifier with Advanced DSP

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 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 pre- amp stages. This is useful for “slaving” a pair of amplifiers together.

30.SPEAKERS: Use these jacks to connect the amplifier to your speaker(s) by means of speaker cables with mono 1/4” plugs. These jacks are wired in parallel. Make sure that the combined 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 additional information.)

32.FUSE: The fuse protects the amplifier from damages caused by a faulty AC power source and/or other prob- lems. If the fuse opens, 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 requirements stated on the rear panel. Do not attempt to defeat the safety ground connection.

WARNING: The speaker output of this unit can exceed 10 Watts and could be a shock injury.

Connection to speakers should be performed by a skilled person in compliance with local building codes. Class 2 wiring is required for speaker cables. Use of external speakers outside the rat- ings stated at the speaker jack may result in a shock injury or damage to the unit.
