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.
