Page 8: Front Panel Controls And Their Functions
Front Panel Controls and Their Functions Input Jack(s): Input jack(s), are 1/4" phone plugs, designed for 1-Meg impedance, guitar-level signal. This input will readily accept pedals/effects without any loss in performance. The design of the Clean Machine amplifier is quite flexible, so we first suggest exploring its performance without any effects or pedals initially. - Page 9 NOTE: There are no internal trimmer pots, other than output tube bias and AC balance controls for the power amplifier stage. There are no internal tone altering controls in a Clean Machine II. These internal controls are best left to professional technicians, who have the proper measuring equipment to set them properly. There are hazardous voltages present in any tube amplifier, even after it has been shut off for some period of time.
- Page 10 (A)-REAR Panel Controls, inputs/outputs, (B)-Effects Loop (A)-REAR panel Controls/input/output jacks AC power cord input: Using the supplied power cord. Connect AC POWER IN on amplifier and to AC power source. Please confirm your line voltage matches that of the amplifier!!! AC power Fuse: This fuse protects the amplifier if any malfunction occurs.
- Page 11 (B)-Effects Loop Using the Loop: When inserting a device like an equalizer, or perhaps a Sonic Maximizer (or similar processor), the loop should be set in series mode. The mix controls on the outboard device can be used to control all effects and the balance between clean and dirty effects.
- Page 12 FOOTSWITCHES: Your Clean Machine is provided with either: a 1- button standard, 2-Button enhanced, or a 4 button “Artist” footswitch depending on your purchase selection. Standard 1 or 2-Way footswitch: Connects via ¼” phone cable (supplied) to rear panel input. Single button controls reverb.
