Half-DIN chassis with seven adjustable frequency bands and selectable low-pass filter. Six-channel, 8-Volt RCA outputs plus front 3.5mm and rear RCA aux inputs and high-level speaker inputs.
Precise tone shaping – Thanks to the 7-band graphic equaliser
Seven sliders target 50Hz, 125Hz, 315Hz, 750Hz, 2.2Khz, 6Khz and 16Khz for narrow boost or cut across the audible spectrum. Independent control of each band allows surgical adjustments without affecting adjacent frequencies.
Accurate frequency control makes it straightforward to remove muddiness or tame harshness, producing a more balanced soundstage in the car. Small changes to individual bands yield noticeable improvements to vocal clarity and instrument separation.
Flexible connectivity – With front 3.5mm aux, rear RCA aux and high-level speaker inputs
Front panel 3.5mm auxiliary input and a two-channel RCA auxiliary input include variable gain adjustments, while high-level speaker inputs accept speaker-level signals from factory head units. Variable gain helps match signal levels to downstream amplifiers.
Easy to integrate with smartphones and aftermarket sources, along with factory systems that lack line-level outputs. Variable gain and high-level inputs reduce the need for extra adapters during installation.
Controlled bass management – Thanks to selectable 12dB low-pass filter and subwoofer level control
Selectable 12dB/octave low-pass filter can be switched between 60Hz or 90Hz, accompanied by an independent subwoofer level control and fader control selection. Ground loop isolation circuitry helps limit interference when adding a subwoofer.
Allows tight, predictable bass roll-off and straightforward blending of subwoofer and main speakers, improving low-end focus and reducing boominess. Sub level and fader control enable tuning to different cabin acoustics and seating positions.
