Always connect the (
+)
speaker wire to the adapter's (
+)
terminal and the (-) speaker wire to the adapter's (-) terminal. When all wires are
connected, plug the adapters into the amplifier's FRONT (and REAR, if using the 4-channel amplifier) preamp inputs.
7. lnput level:
i
From high-level
source
Use this switch along with the gain control to set the amplifier's input level. lf use а radio's RCA-level outputs, set the lnput Level switch to the
"LO" position. lf using high-level outputs, start the control-setting process with the lnput Level switch set in the "Н11" position.
Note: lf you have connected your amplifier to the audio system's speaker outputs, the audio signal may fail to play. lf this happens, change the
lnput Level switch to the "Н12" position. The "Н12" position includes а circuit designed to fool this type of factory audio system into "seeing" а
speaker connected to its input.
lmportant: The "Н12" setting should never Ье used when the amplifier is connected to ап aftermarket head unit's line-level (RCA-type) outputs.
8. Grossover filter selectors (X-OVER):
Crossove r-f i lte r se I ectors.
• LP: Low pass. Choose this setting if you're connecting а subwoofer(s), or want to provide а low-pass filter for separate mid-bass speakers.
• FULL: Full range. Choose this setting if you're connecting full-range speakers, and not using а subwoofer in your system.
• HP:High pass.Choosethis setting to prevent lowbass from reaching midrange orfull-rangespeakerswhenyou're using asubwoofer in yoursystem.
