STEP 6. (6) TIME CORR. (Time Correction)
Due to the wide variety of installation and system design possibilities available, bass performance may not always be optimized as a result of speaker placement relative to the listening position. Sound waves may not reach the listener's ear at the same time as other speakers, especially in a multiple subwoofer configuration. Such differences in phase can result in muddy (unclear) bass or even a complete cancellation in the frequency response. Therefore, both the
STEP 7. (7) PHASE
Phase control allows you to flip the polarity of the subwoofer without actually reversing the physical connections. This convenient feature is useful when the subwoofer is in a position that could result in some cancellation, causing diffused, unclear bass. It is recommended to try both settings (0°/180°) to determine which is best for your particular system.

The Amp Set menu performs two functions. Firstly, by setting the amplifier ID number

STEP 9. (9) SAFE MODE (Output Disable)
SAFE MODE provides a simple way to safely adjust the all DSP functions with the amplification circuit turned off, eliminating the possibility of speaker damage during setup. When SAFE MODE is set to “ON”, it literally shuts down the high current draw output stage of the amplifier, and is essentially an “output disable” function. This is the only amplifier function that does not engage/disengage in real time, but requires the remote lead to be cycled off/on. Therefore, if it is accidentally set to “ON” during programming, there will be no output the next time the amplifier is activated. Additional uses include: bench setup with very small or low current DC supply, amp valet, and system troubleshooting.
SETTING SAFE MODE TO "OFF"
•Press and depress the "MODE" button until you are in mode "9" (SAFE MODE).
•Push "ENT" and push "ENT" again to select
•Toggle until "OFF" is displayed.
•Push "DISP" to exit.
Note: This setting will not take effect until the amp is turned off and then on again.

STEP 0. (0) MEMORY
Memory Mode allows you to store all amplifier settings in an auxiliary backup memory. Once stored, additional tweaks or adjustments can be made while retaining the ability to recall the original settings at a later time. Note: This is simply a convenience feature, since all settings are saved in real time as adjustments are made, and will remain even if power is lost during setup.
Typical causes for little or no output
1)Safe Mode is on: Go to Step 9 (Mode 9 on the amp) and set to “OFF”, then cycle amp power.
2)Subsonic and LPF frequency selections overlap or are too close together: Adjust the crossover properly
3)If using
display mode (voltage or temperature) and adjust the level control.
4)Defective or broken RCA cables): Replace RCA connectors
5)Blown fuse: Replace Fuse with proper value
6)Remote trigger is not active: Check remote
7)Bad ground or power connection: Check and replace ground connector
