TYPICAL APPLICATIONS
The Powerflex 6250 is essentially three stereo amplifiers in one chassis, each with dual stereo, dual mono, and
bridged mono capabilities, while the Powerflex 4400 is two stereo amplifiers (four channels), but with more power per
channel than the 6250. The ability to easily mix and match various configurations is what puts the "flexibility" in
Powerflex. Input connections can be 1/4" phone plug, XLR, or hard-wired with two-piece Euroblock connectors, while
speaker outputs can be either "banana" type plugs or wire crimped spade terminals. Note: The Powerflex 6250 is used
for the following application details, but the 4400 is used in a similar fashion, to a maximum of four channels.
