This jumper-cap adjustment module lets you shape bass and treble by configuring four jumpers on bridges A, B, C, and D. It is designed to be used with speaker systems that support jumper-cap tuning on these bridges. Key benefits and how it helps - Precise bass control: A sets the lower limit of the bass range and B sets the upper limit, enabling you to tailor the bass response to your speaker and room. - Distortion reduction: If distortion occurs when bass is set too high, you can limit very low bass by removing the cap on bridge A. - Flexible bass boost or reduction: Removing the cap on Jumper B increases bass; leaving the cap on Jumper B reduces bass. - Treble adjustment: Jumpers C and D control the high frequency range; when the caps on C and D light up, the treble is the loudest. - Simple, non-invasive tuning: Changes are made via jumper caps on predefined bridges, without altering other circuit elements. Important attributes - Function: Bass range control via jumpers A and B; high frequency control via jumpers C and D; cap status (on/off or illuminated) indicates active tuning. - Compatibility: Compatible with speaker setups that use jumper-cap tuning on bridges A–D. - Performance: Enables distortion management and customized bass/treble balance for improved listening clarity. Use scenarios - Home audio with bass distortion: If you notice distortion at high bass levels, remove the cap on bridge A to limit super low bass and reduce distortion. - Studio or critical listening: Adjust B to tighten or deepen bass presence to suit the mix without altering midrange or treble. - Bright or detailed speakers: Ensure the caps on Jumpers C and D are illuminated to achieve the desired treble emphasis when needed. Note: The bass behavior is: removing B’s cap increases bass, while keeping B’s cap on reduces bass. Cap status on A reduces very low bass, addressing distortion. Cap status on C and D amplifies treble.
