The boundary layer design sits flat on a surface or inside a kick drum shell, using the pressure zone effect to capture a full, phase-coherent low-frequency signal without the comb filtering that conventional stand-mounted microphones can produce in reflective enclosed spaces.\u003c\/p\u003e \u003cp\u003eWhen placed inside a bass drum, the E 901 captures the deep fundamental and body of the kick without requiring a microphone stand or boom arm, simplifying stage setup and eliminating a potential trip hazard. The half-cardioid pattern rejects sound from behind the microphone, which reduces bleed from other drums and stage sources. The E 901 is often used as the inside kick microphone in a dual-mic configuration, paired with a dynamic microphone at the resonant head for attack.\u003c\/p\u003e \u003ch2\u003eKey Features\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eHalf-cardioid condenser boundary layer microphone\u003c\/li\u003e \u003cli\u003eOptimized for bass drums, piano, and low-frequency sources\u003c\/li\u003e \u003cli\u003eFlat boundary design for inside-kick placement without a stand\u003c\/li\u003e \u003cli\u003ePhase-coherent capture in the pressure zone\u003c\/li\u003e \u003cli\u003e3-pin XLR output, requires 48V phantom power\u003c\/li\u003e \u003cli\u003eIncludes carrying pouch\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eProfessional Applications\u003c\/h2\u003e\u003cp\u003eCommonly deployed in church, house of worship, and professional AV environments.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInside bass drum microphone for live and studio kick capture\u003c\/li\u003e \u003cli\u003ePiano lid microphone for low-frequency piano reinforcement\u003c\/li\u003e \u003cli\u003eCajon and percussion box internal microphone placement\u003c\/li\u003e \u003cli\u003eLow-frequency ambient capture in recording environments\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e \u003ch3\u003eHow does the E 901 differ from the E 602 II or E 902?\u003c\/h3\u003e \u003cp\u003eThe E 901 is a boundary layer microphone designed to sit inside the kick drum shell. The E 602 II and E 902 are conventional microphones placed on a stand or boom. The E 901 captures the body and fundamental, while the E 602 II and E 902 capture more attack from outside or at the port.\u003c\/p\u003e \u003ch3\u003eCan I use the E 901 and a conventional kick mic at the same time?\u003c\/h3\u003e \u003cp\u003eYes. A common technique is to place the E 901 inside the drum for body and a dynamic microphone at the resonant head port for attack. Blend the two at the console for a complete kick sound.\u003c\/p\u003e \u003ch2\u003eRelated Equipment and Workflow Compatibility\u003c\/h2\u003e \u003cp\u003eThe E 901 connects via standard XLR and requires 48V phantom power.
