** Classic: {{Classic}} 750 Watts of power and therefore requires a good input power supply that is rated at least 1400 Watts. As a general guideline, you should budget at least 1000 Watt per system.

* Only use inverter<ref>inverter [http://powerequipment.honda.com/generators/inverter-generator-advantages Honda article on inverter generators], [http://www.yamahaef2000is.com/conventional_generator_vs_inverter_generator.html Yamaha article on inverter generators]</ref> type generators. These generators will provide clean sine wave power that makes them safe for use with sensitive equipment such as computers, laptops, and the {{L1}}. Generators of the type commonly used in construction should be avoided.

=== Pure Sine Wave Inverter ===

* Only use '''pure sine wave inverter'''<ref>inverter [http://powerequipment.honda.com/generators/inverter-generator-advantages Honda article on inverter generators], [http://www.yamahaef2000is.com/conventional_generator_vs_inverter_generator.html Yamaha article on inverter generators]</ref> type generators. These generators will provide clean sine wave power that makes them safe for use with sensitive equipment such as computers, laptops, and the {{L1}}. Generators of the type commonly used in construction should be avoided.

* If performing with the {{L1}} at a gig where an unfamiliar generator is being used, it is advisable to bring a multimeter and monitor the output voltage of the generator. If the reading is above 140 V or below 100 V, then the Bose system may not work reliably.

* Beware if you are at a gig where you must plug into a generator that also has something with a large compressor (like a refrigerator or freezer) plugged into it. When the compressor shuts off, there may be an excess of energy going through the line causing a significant spike in voltage going to the {{L1}}. Conversely, when the compressor starts up, there may be a significant power drop-off from the {{L1}}.

=== Modified Sine Wave Inverters ===

Inverters can be pretty abusive to many systems. Many create a “stepped sine wave” or "modified sine wave" (the red trace below). Those edges can wreak havoc in many electronic systems, especially switching amps and other circuits with critical timing requirements. They can also cause microprocessors to misbehave. Further, these waveforms can also age electrolytic caps much faster than true sine waves. We do not recommend the use of modified sine wave battery inverters for any electronics you care about.<ref>Modified sine wave inverters are not recommended. Source: Bose Engineering</ref>.
