IMPORTANT SAFETY INFORMATION The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of un-insulated ‘dangerous voltage’ within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. • Servicing: Do not attempt to service this product yourself as opening or removing covers may expose you to dangerous voltage or other hazards. • Refer all servicing to qualified service personnel.
EMI To reduce the possibility of outside electrical interference during performance, operate your amplifier and instrument away from appliances/equipment that generate high levels of electronic/electromagnetic noise. This may include, but is not limited to: fluorescent lighting, refrigerators, motors, mobile phones, radios, computers etc. BEFORE USING YOUR AMPLIFIER Speakers Always ensure the correct speaker load (Ω) is connected to the SPEAKER OUTPUT terminal(s) at all times during operation.
FRONT PANEL FEATURES (RIGHT TO LEFT) Input Jack Socket Plug your instrument into this jack socket. Gain Control (Channel B) This controls the gain level of Channel B. Shape Control (Channel B) This controls the frequency sweep on Channel B. It adjusts between all midrange (minimum setting) to all bass and treble with no midrange (maximum setting). Volume Control (Channel B) This controls the output volume of Channel B. Gain Control (Channel A) This controls the gain level of Channel A.
This controls the treble response of Channel A. Volume Control (Channel A) This controls the output volume of Channel A. Attenuator Control This controls the amount of attenuation for both channels. Turn clockwise to reduce the overall volume level. This can be defeated using a latching footswitch for a volume boost. Channel Switch Use any latching footswitch to change channel using this socket. (Note – The front panel channel toggle switch must be switched to Channel A for the footswitch to function.
REAR PANEL FEATURES SEND / RETURN (Effects Loop) Use the ‘Send’ jack socket to connect to the input of time based effects pedals such as delay, chorus, etc. Use the ‘Return’ jack socket to connect to the effects pedal’s output. FOOTSWITCH CHANNEL: Use any latching footswitch to change channel remotely. Note – The front panel channel toggle switch must be switched to Channel A for the Channel footswitch to function. ATTENUATOR: Use any latching footswitch to defeat the Attenuator control.
VALVES AND FUSES CAN FAIL AT ANY TIME! From time to time output and preamp valves may fail. The fuse on the rear labelled ‘HT FUSE’ will blow if any of the power amp/output stage valves fail. This helps to protect the rest of the circuitry. We suggest that output valves are changed at least once a year and that all class AB models (50 watts and above) will benefit from having the bias checked and adjusted. Bias checking must be carried out by a qualified engineer.
