Sennheiser MD 445 Handheld microphone (high-rejection super cardioid, dynamic) with 3-pin XLR-M - 508828

Product Overview

The Sennheiser MD 445 is a high-rejection super-cardioid dynamic handheld microphone built for productions where maximum feedback rejection and focused vocal reproduction are the primary requirements. A newly developed aluminum-copper voice coil delivers fast transient response and nuanced high-frequency character in the direct vocal range, while the high-rejection super-cardioid pattern minimizes ambient stage noise and monitor bleed more aggressively than standard super-cardioid designs. The MD 445 is the appropriate choice for loud stage environments where standard dynamic microphones cannot maintain adequate gain before feedback.

Product Description

The MD 445 uses a high-rejection super-cardioid polar pattern, which provides a narrower acceptance angle than both cardioid and standard super-cardioid designs, resulting in significantly higher gain before feedback in environments with loud monitor wedges or high ambient stage SPL. The aluminum-copper voice coil is lighter and more responsive than standard copper-wound designs, contributing to the direct, close character of the vocal reproduction and enhanced transient detail in the high-frequency range. The large diaphragm diameter supports a full, rich low-mid response that gives vocals body and weight without requiring additional low-end processing at the console. A spring-mounted capsule isolates the transducer from body-borne noise from handling and cable movement—a practical requirement for performers who move aggressively with the microphone. The hum compensation coil rejects EMI from stage lighting dimmers and power transformers. Like all dynamic microphones, the MD 445 requires no phantom power, simplifying cabling and console infrastructure. The XLR-3M output is compatible with all standard mixing consoles and stage boxes.

Frequently Asked Questions

Q: What distinguishes the MD 445 from the MD 435?

Both use aluminum-copper voice coils and rugged metal construction. The MD 445 uses a high-rejection super-cardioid pattern that provides a narrower acceptance angle and higher gain before feedback than the MD 435's standard cardioid. For stages with loud wedge monitors or environments where feedback is the primary constraint, the MD 445 is the appropriate choice. The MD 435 is more appropriate where performer movement relative to the mic axis is large and a wider acceptance angle is needed.

Q: Does the MD 445 require phantom power?

No. Like all dynamic microphones, the MD 445 is passive and does not require phantom power from the console.

Q: Is the MD 445 appropriate for house of worship applications?

Yes. The high-rejection super-cardioid pattern is particularly valuable in houses of worship where ceiling or balcony speakers are close to the stage and feedback margins are tight. The noiseless operation and standard cardioid-style handling make it easy for non-technical users to operate.

Q: What are typical high-rejection super-cardioid monitor positions?

A high-rejection super-cardioid pattern has its null points at approximately 125 degrees off-axis on each side. Monitor wedges should ideally be positioned at these null points relative to the microphone axis for maximum feedback rejection. This differs from a cardioid's 180-degree rear null and should be factored into monitor placement decisions by the monitor engineer.
