6. nce Select Switch What this does is allow you to hook up external speaker cabinets and maintain maximum power As mentioned the internal speakers are 8 Ohms so when using the internal speakers only set the Impedance Selector to 8 Ohms If and when you hook up another cabinet you have to make sure the external cabinet is either 4 Ohms or 8 Ohms only Do not use a 16 Ohm cabinet Please read below for cor rectly hooking these up IMPORTANT NOTE DO NOT use an external speaker cabinet with a Wattage rating of less than 30 Watts or 40 watts if you are using a 4 Ohm external speaker cabinet or less than the output power you ve selected with the POWER SELECT control see page 19 in A Guitarists Guide lf you ignore this you could end up blowing a speaker and that s not recommended ANOTHER IMPORTANT NOTE ALWAYS use speaker cables unshielded to connect speaker cabinets NEVER use guitar shielded cables AD60VTX SPEAKER CONNECTION CHART Please read the below chart to make sure you correctly connect external speakers to the AD60VTX Keep in mind that the speaker jacks are wired in Series which means that the total impedance of the speakers equals the sum of the impedance of the internal 8 Ohms plus the external speaker 4 or 8 Ohms As an example the AD60VTX contains an internal 8 Ohm speaker when you hook up an additional 8 Ohm speaker you ll set the impedance select switch on the back of the amp to 16 Ohms 8 8 16 Simple righ
