sE Electronics BL8 - Semi-Cardioid Condenser Boundary Microphone

sE Electronics BL8 – Semi-cardioid Condenser Boundary Microphone

The sE Electronics BL8 is a boundary microphone designed to capture deep low end and ultra-fast transient response. It features the same 1/2" True Condenser capsule as the legendary sE8, with a gold-plated 3-micron diaphragm, for exceptional reproduction in kick drum, cajon, piano, and room applications. Its semi-cardioid pattern minimizes unwanted reflections while maximizing gain-before-feedback. With a pad, low-cut filter, and a "Character" switch (Classic/Modern), the BL8 adapts to any source, often eliminating the need for an additional kick drum mic. Its rugged construction and compatibility with KellyShu suspension systems make it ideal for touring and live performance.

Frequently Asked Questions

• Does it require special assembly? It sits directly on a surface; optionally, it can be hung on KellyShu Flatz.
• How do I select the Character mode? Classic mode offers a neutral timbre; Modern mode boosts low mids for added presence.
• Do I need phantom power? Yes, 48V phantom power for your condenser capsule.
• Does the pad affect the tone? It only attenuates the level; it maintains the frequency response unchanged.
