SubZero SZM-11 Dynamic Vocal Microphone
The SubZero SZM-11 is a cardioid dynamic microphone designed for both live performance and studio recording. Positioned as an affordable entry-point vocal mic, it features a premium capsule engineered for accurate voice reproduction and high off-axis rejection.

Overview
The SubZero SZM-11 is a dynamic vocal microphone designed to provide clear, nuanced audio reproduction for singers and public speakers. It is constructed to handle the rigours of frequent use, making it suitable for both stage environments and studio settings. The microphone focuses on delivering record-ready sound with minimal external setup requirements.
Key Features and Design
At the core of the SZM-11 is a premium capsule with a cardioid polar pattern. This unidirectional pickup pattern is essential for live performance as it focuses on the sound source directly in front of the mic while providing excellent off-axis rejection. This design helps to eliminate unwanted ambient noise and reduces the risk of feedback.
The microphone also features an internal protective foam insert. This integrated layer acts as a built-in pop filter, designed to attenuate plosives and wind noise without the need for an external shield. The chassis is built to be rugged, intended to protect the internal components from superficial damage and mechanical shock during transport or performance.

Sound Character
The SZM-11 is tuned for accuracy, aiming to capture the nuances of a performer's voice. Unlike some entry-level microphones that may sound muffled, the SZM-11 is designed to be articulate. Its cardioid pickup ensures that the room's focus remains on the primary subject, providing a clean signal that is relatively free from the coloration of surrounding room acoustics.
Comparison to Industry Standards
In terms of function and form factor, the SZM-11 occupies the same space as several industry-standard dynamic microphones. While it sits at a significantly lower price point (approximately £30), it competes for the same utility as the Shure SM58 and the Sennheiser e935.
Compared to the Shure SM57, which is often used for instruments, the SZM-11 is more explicitly tailored for vocals due to its integrated foam insert. While high-end broadcast microphones like the Electro-Voice RE20 or the Sennheiser MD 441-U offer more complex acoustic designs, the SZM-11 provides a straightforward, durable solution for users who require reliable cardioid performance on a budget.

Frequently asked questions
- What type of microphone is the SubZero SZM-11?
- The SZM-11 is a dynamic microphone, which means it uses a diaphragm, voice coil, and magnet to convert sound into an electrical signal. This design is generally robust and does not require external power.
- Does the SZM-11 require phantom power?
- No, as a dynamic microphone, the SZM-11 does not require +48V phantom power to operate. It can be plugged directly into any standard XLR microphone input on a mixer or audio interface.
- What is the polar pattern of the SubZero SZM-11?
- It features a cardioid polar pattern. This means it is most sensitive to sound coming from the front and rejects sound from the rear, helping to prevent feedback on loud stages.
- Can the SZM-11 be used for studio recording?
- Yes, while designed for live use, its premium capsule and accurate reproduction make it suitable for studio vocal tracking. The built-in foam insert helps achieve 'record-ready' sounds immediately.
- Do I need a separate pop filter with this microphone?
- The SZM-11 includes a protective foam insert designed to eliminate the need for an external pop filter or windshield. This helps reduce plosive sounds like 'p' and 'b' during performance.
- Is the SubZero SZM-11 durable enough for touring?
- The microphone features a rugged build designed to protect internal components from superficial damage. This construction is intended to ensure a long-lasting life even with frequent stage use.
- How does the SZM-11 handle background noise?
- Thanks to its cardioid capsule, it provides excellent off-axis rejection. This ensures that undesirable noise and room ambience from the sides and back are minimized.
- What is the typical price for the SubZero SZM-11?
- The microphone typically retails in the price range of approximately £30. This makes it an accessible option for schools, venues, and home studios.
