• HPF–(high pass filter) Select
this filter when the amplifier will

the "bass" going to these
speakers.
Tri-mode/Three channel operation
An amplifier is usually configured for tri-mode
operation when you want to use one amplifier
to drive a pair of front speakers and
subwoofer(s). In other words, when you want
to drive a complete system with one amp.
Your Jensen amplifier is capable of tri-mode
operation.
Important
Tri-mode operation requires using "passive
crossovers". These crossovers are available
at your local retailer or install shop. Failure to
install these filters may damage your
amplifier and/or your speakers.
