• BOOST Frequency: Allows you to select a specific frequency range (40 Hz to 90 Hz) to boost for enhanced bass impact.
• HIGH CUT Control: Sets the crossover frequency for the subwoofer (70 Hz to 150 Hz). This determines the upper frequency limit of the subwoofer's output and the lower frequency limit of the signal sent to your full-range speakers via the 'PASS THRU' outputs.
• Kusintha kwa PHASE: Inverts the phase of the subwoofer's output. Experiment with this setting to achieve optimal bass alignment with your main speakers.
• LIMIT LED: Illuminates when the internal limiter is active, indicating that the signal is too high and clipping may occur. Reduce the input level or the LEVEL control if this LED is constantly lit.
