Setting The Crossover; Adjusting The Subwoofer; Selecting Subwoofer Phase; Setting The Dynamic Bass Optimizer - Infinity KAPPA K2 Owner's Manual And Installation Manual

Setting the crossover (K2, K4, K600)
Properly setting crossover filter selectors optimizes frequency distribution for efficient speaker operation and best sound.
Step 1:
Use the slider controls to select low-pass (LP), FULL, or high-pass (HP).
• LP: Low pass. Choose this setting if you are connecting a subwoofer(s) or want to provide a low-pass filter for separate mid-bass speakers.
NOTE:
the K600 and K1000 feature low-pass crossovers only.
• FULL: Full range. Choose this setting if you are connecting full-range speakers and are not using a subwoofer in your system.
• HP: High pass. Choose this setting to prevent low bass from reaching midrange or full-range speakers when you are using a subwoofer in
your system.
Step 2:
Use crossover-filter frequency controls to adjust crossover point settings for coaxial speakers and subwoofers to suit listener preference.
Turn the dials to the left to lower the crossover point and to the right to raise the crossover point. Exact crossover settings for coaxial speakers
and subwoofers finally depend on your listening preferences. NOTE: crossover point does not apply in FULL mode.

Adjusting the subwoofer

Select INT if you're connecting a subwoofer to the K5 amplifier and if your source unit does not feature a subwoofer output (this will send a
summed audio signal to the subwoofer). If your source unit does feature a subwoofer output, select EXT to connect to that output.

Selecting subwoofer Phase (K600, K1000, K5)
You can choose a subwoofer phase output of 0° or 180°. To check your sub's phase, play music with lots of bass and listen as another person
slowly flips the 0/180 degree phase switch back and forth. The correct setting is the one that gives you more bass. If you don't detect any real
difference, leave the switch in the 0 setting.

DBO: Variable Subsonic High-Pass Filter with Variable Boost (Q)
• For woofers in tuned (vented) enclosures, set the frequency control to a value 10Hz below the enclosure's
resonance (tuned frequency).
• For woofers in sealed enclosures, set the control to any value you prefer between 30Hz and 50Hz.
• Set the Boost control according to your preference being careful not to apply excessive boost that would
damage your woofer(s).
• DBO Boost control provides up to 12dB of boost, slightly above the high-pass filter's frequency.
• DBO High-Pass filter Frequency control is variable between 10Hz and 80Hz.
