NOTE: The ground switch is not functional on 220/240 volt models. FUSE (3) A 5 amp fuse is located within the cap of the fuse holder. Tt must be replaced with the same type and value in order to avoid damage to the equipment and to prevent voiding the warranty. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair. WARNING: The fuse should only be replaced when the power cord has been disconnected from its power source. REMOTE FOOTSWITCH JACK (4) Provided for the connection of the supplied remote footswitch. Footswitch is used to select the channel from clean to lead and to select the effect, reverb, and tremolo on or off. LEVEL (5) Adjusts the voltage level of the effects loop. If the send level is too low for a particular effects device, turn the control clockwise; if too high, counterclockwise. EFFECTS SEND (6) Output for supplying signals to external effects or signal processing equipment. 5 L SWITCH LOGIC EFFECTS RETURN (7) Input for returning signals from external low-level effects or signal processing equipment. NOTE: Signals are supplied to outboard effects or signal processing units by patching from the effects send jack (6) output into the outboard unit(s) and back into the effects return (7) input using shielded cable with l/4” phone plugs. Only non-gain effects devices (chorus, reverb, delay, etc.) should be used in the effects loop. Remote (on/off) selection of outboard effects devices can be achieved using the footswitch. PREAMP OUT (8) The preamp out jack can be used to route the amplified signal to a mixing console, tape recorder, etc. Connect the preamp output using a shielded cable to an input of the tape recorder, mixer, etc. This patch does not affect the operation of the amplifier. IMPEDANCE SELECTOR SWITCH (9) Use to select the appropriate impedance of the speaker enclosure(s). If two enclosures of equal impedance are used, the switch should be set at one-half of that value (e.g., two 16 ohm enclosures: set switch to 8 ohms; two 8 ohm enclosures: set switch to 4 ohms). When using only the internal speakers, the Impedance Selector Switch should be set to 16 ohm. SPEAKER OUTPUTS (10) Paralleled l/4” output jacks for connecting speaker enclosure(s) to the amplifier (minimum 4 ohms). When using more than one enclosure, be sure to calculate the total impedance and set the impedance switch (9) accordingly. (See section on Impedance Switch.) IMPORTANT: Use only high quality, unshielded cable for speaker connections. SPECIFICATIONS THIS BLOCK DIAGRAM PRE POST SHOWS SIGNAL FLOW WITHIN THE UNIT.
