18. AC Line Cord (not shown): The grounded power cord should only be plugged into a grounded power outlet that meets all applicable electrical codes and is compatible with the voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection. 19. FOOTSWITCH JACK: Use this jack to connect the cable of the footswitch (supplied) for remote control of channel switching and the DSP effect. (Tip = channel select, ring = DSP select.) Refer to the section below for additional information about how the footswitch can be used to save DSP settings fro each channel.

20. LINE OUT JACK: Use this jack to send a line level signal from the amplifier to an external amplifier, a mixing console, or the input of an external effect. 21. LINE IN JACK: Use this jack to return the signal from an external effect to the amplifier. 22. EXT. SPEAKER JACK: Use this jack to connect the amplifier to a 16 ohm extension speaker. The internal speaker is not disconnected when this jack is in use. The impedance switch (#23) must be set to the 8 ohm position when a 16 ohm extension speaker is used.

23. IMPEDANCE SWITCH: Use this switch to set the amplifier�s output impedance to match the impedance of the speaker(s). The impedance of the speaker(s) inside the amplifier is 16 ohms. The switch is set at the factory to the 16 ohm position. When a 16 ohm extension speaker cabinet is used (see #22), this switch must be set to the 8 ohm position. Use the tip of a small flatblade screwdriver to slide the switch to the proper position.

Using the Footswitch to Save DSP Settings:
The two-button footswitch (supplied) may be used to save two DSP settings for each channel. (1) Connect the cable of the footswitch to the Footswitch jack (#19) on the back of the VFX amplifier. (2) Click the footswitch buttons until both LEDs are not illuminated. Channel A is now active. (3) Select one of the DSP settings - for example, Large Reverb. Click the �EFFECTS A/B� footswitch button (the EFFECTS A/B LED will illuminate). Select another DSP setting - for example, Vibrato Slow. Click the �EFFECTS A/B� footswitch button again (the #EFFECTS A/B LED will go out) and the Large Reverb DSP setting is recalled. You have now programmed the footswitch to recall two DSP settings for Channel A: Large Reverb (CHANNEL LED not illuminated) and Vibrato Slow (EFFECTS A/B LED illuminated). You may repeat this procedure for Channel B. Click the �CHANNEL� footswitch button (CHANNEL LED illuminated), then repeat step 3 for Channel B using different effects.
