Front panel operation

1.Input – Plug your guitar into this 1/4" unbalanced input using a TS cable.

2.Program Up/Down Buttons – Change the program number with these buttons. When pressed together, they put the unit into both Bypass and Mute modes and access the tuner.

3.Display – indicates bank and program, shows parameter values, and displays the pitch in tuner mode.

4.EFFECT Knob – puts the Coolfire in PLAY mode or EDIT mode. You are in EDIT mode when this knob is set to anything other than PLAY.

5.VALUE Knob – adjusts parameter values and program numbers; stores changes.

6.MASTER VOLUME Knob – controls the volume of the signal sent to the speaker, headphones, STEREO LINK OUTPUT and SPEAKER OUTPUT.

7.HEADPHONES Jack – Plug in your headphones using a 1/4" stereo plug.

8.Power Switch – turns the Coolfire on and off.

Rear panel operation

1.Fuse – Replaceable fuse. See the rear panel of the Coolfire for details.

2.Power Cord – Plug this cord into a proper AC outlet. See the rear panel for details.

3.FOOTSWITCH UP/DOWN INPUT – Plug footswitches into these 1/4" jacks. Footswitches serve the same functions as the Program Up and Down buttons.

4.EXPRESSION PEDAL INPUT – Plug an expression pedal into this 1/4" jack for easy control over EFFECT parameters.

5.AUX INPUT – Plug a CD player or other audio device into these RCA jacks and play along!

6.STEREO LINK OUTPUT – Use a 1/4" TS cable to connect this jack to the input of another amplifier for true stereo. The Coolfire provides true stereo output instead of the standard mono; many of the Coolfire’s excellent effects will sound even better when you listen to them in stereo. If you don’t have a second amplifier, you can enjoy the stereo effects by listening with headphones.

7.SPEAKER OUTPUT – Use a 1/4" TS cable to connect this jack to an external 8-ohm speaker. Doing so disconnects the internal speaker.
