Saramonic SR-WM4C Wireless Microphone System

Saramonic SR-WM4C Wireless Microphone System

The SR-WM4C is a compact, lightweight wireless microphone system designed for professional audio capture in film, television, and live event production. Its sleek black chassis houses four independent VHF channels, allowing multiple performers or speakers to be recorded simultaneously without interference.

Key Features

• Four-Channel Capability: The system supports up to four separate audio streams, each operating on its own frequency. This is ideal for interviews, panel discussions, or multi‑person performances where clear separation of voices is essential.
• VHF Frequency Range: Operating in the VHF band ensures minimal interference from other wireless devices and provides a stable signal over typical shooting distances.
• Lavalier Microphone Design: The built‑in lavalier microphone offers omnidirectional pickup, capturing sound evenly from all angles. Its small size makes it discreet and comfortable for the wearer.
• Compact Dimensions: Both the transmitter and receiver measure 102 mm × 62 mm × 45 mm, making them easy to mount on camera rigs, handheld grips, or other equipment without adding bulk.
• Lightweight Construction: Each unit weighs only 80 g, reducing fatigue for operators and ensuring that the system does not interfere with camera balance or movement.
• 3.5 mm (1/8‑inch) TRS Output: The receiver outputs a standard 3.5 mm stereo plug, compatible with most cameras, recorders, and audio interfaces.
• Battery Powered: Both the transmitter and receiver are powered by two AA (LR6) alkaline batteries, providing ample runtime for extended shoots.

Design & Build Quality

The SR-WM4C’s chassis is constructed from durable polymer that resists impact and environmental stress. The matte black finish not only looks professional but also helps reduce glare on camera surfaces. Each unit features a secure latch mechanism to keep the battery compartment closed during operation, preventing accidental disconnections.

Audio Performance

The integrated lavalier microphone delivers clear, natural sound with a frequency response tailored for human voice capture. Its omnidirectional pattern ensures consistent pickup regardless of slight movements or changes in speaker orientation. The receiver’s 3.5 mm output provides a clean analog signal that can be directly fed into a camera’s audio input or an external recorder without the need for additional adapters.

Operational Flexibility

With four independent channels, the SR-WM4C allows production teams to assign each channel to a different performer or location. This flexibility is particularly useful in multi‑camera setups where each camera may require its own dedicated audio feed. The system’s VHF operation also means that it can be used in environments with limited spectrum availability, such as studio sets or indoor venues.

Installation & Setup

Setting up the SR-WM4C is straightforward:

1. Insert two AA batteries into both the transmitter and receiver.
2. Connect the receiver’s 3.5 mm output to your camera or recorder.
3. Select a channel on both units (typically labeled 1–4).
4. Attach the lavalier microphone to the performer’s clothing, ensuring it is positioned near the mouth for optimal pickup.
5. Power on the transmitter and receiver; the system will automatically lock onto the selected frequency.

Use Cases

• Film & Television: Ideal for capturing dialogue in interviews, talk shows, or documentary footage where multiple speakers need to be recorded simultaneously.
• Live Events: Perfect for conferences, seminars, and live broadcasts that require clear audio from several presenters without the clutter of cables.
• Broadcasting: The system’s reliable VHF transmission makes it suitable for radio or television studios where interference must be minimized.
• Educational Settings: Teachers and lecturers can use the SR-WM4C to record lectures or presentations with multiple participants, ensuring each voice is captured distinctly.
