APX1000

All APX series ampliﬁers are Class D, meaning they are lightweight,

have high dollar-per-watt ratios and are very efﬁcient in converting

available power into usable wattage without generating the type

of heat associated with other designs. Each APX ampliﬁer has

balanced XLR/quarter-inch combo inputs that enable connection

to balanced or unbalanced audio sources, while Speakon® NL-4

connectors and binding posts outputs provide for connection to

virtually any passive speaker system.
