Its compact aluminum chassis houses protection circuits and a switchable operating mode, enabling flexible use with active or passive subs, or as an independent mono amplifier in multi-amp setups.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the G2 PRO improve bass performance in my system?\u003c\/h3\u003e\n\u003cp\u003eThe G2 PRO provides a selectable SUB mode and an adjustable low-pass filter so you can dial in the subwoofer’s crossover point for tighter, more accurate bass. Built-in protection circuitry prevents audible distortion at high output, helping the sub stay clean under load.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSUB mode with dedicated SUB output for active subwoofers\u003c\/li\u003e\n  \u003cli\u003eLow-pass frequency adjustment from 40–300 Hz to match speaker response\u003c\/li\u003e\n  \u003cli\u003eHigh output headroom from the TPA3255 amplifier topology\u003c\/li\u003e\n  \u003cli\u003eProtection circuit reduces clipping and audible artifacts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use the G2 PRO with passive speakers or only with subwoofers?\u003c\/h3\u003e\n\u003cp\u003eThe G2 PRO is versatile: flip the PBTL\/SUB switch to operate as a full-frequency mono amplifier or as a subwoofer-dedicated amp. It can drive passive subwoofers directly or feed active subs via the SUB output, and two units can run left and right channels independently for stereo setups.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePBTL (full-frequency) mode powers passive speakers and subwoofers\u003c\/li\u003e\n  \u003cli\u003eSUB mode outputs a filtered low-frequency signal for active subs\u003c\/li\u003e\n  \u003cli\u003eCompatible with bookshelf, floorstanding, ceiling, and outdoor speakers\u003c\/li\u003e\n  \u003cli\u003eUse two G2 PRO units to separate left\/right channels and avoid interference\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat controls and connections let me tune the sound?\u003c\/h3\u003e\n\u003cp\u003eThe front and rear-panel controls let you set gain levels and the low-pass cutoff so the amplifier integrates smoothly into varied systems.
