2. Setup

2.1 Unpacking and Inspection

Carefully remove all components from the custom carrying case. Verify that the package contains the SMX-100 microphone, a shoe-mount mic clip, and a foam windshield. Inspect all items for any signs of damage.

2.2 Mounting the Microphone

1. Attach the provided shoe-mount mic clip to your camera's hot shoe or a compatible microphone stand.
2. Gently insert the SMX-100 microphone into the mic clip, ensuring it is securely held.

2.3 Connecting the Microphone

The SMX-100 features a hard-wired 5-pin XLR connector. This microphone requires external phantom power ranging from 11 to 52 VDC for operation.

1. Connect the 5-pin XLR connector from the SMX-100 to a compatible audio input on your camera, mixer, or audio recorder. Ensure the input provides the necessary phantom power.
2. Verify that the phantom power is enabled on your recording device's input channel.

2.4 Installing the Windshield

Slide the foam windshield over the microphone's head. The windshield helps to reduce wind noise and plosives, improving audio clarity, especially in outdoor environments.

3. Operating Instructions

3.1 Powering On

The SMX-100 does not have an internal power switch. It is powered by external phantom power supplied through the 5-pin XLR connection. Ensure your recording device's phantom power is activated for the connected input channel.

3.2 Mid-Side (M-S) Stereo Recording

The SMX-100 utilizes a Mid-Side stereo configuration. This setup captures a central (Mid) signal and a bidirectional (Side) signal. These two signals are then decoded to produce a stereo image.

• The Mid capsule captures sound directly in front of the microphone (cardioid pattern).
• The Side capsule captures sound from the left and right (figure-8 pattern).
• M-S decoding can be performed in your audio recorder or editing software to adjust the stereo width after recording.
• This configuration allows for excellent mono compatibility, as the Mid signal can be used independently.

3.3 Optimal Placement

Position the microphone with the front end pointing towards your primary sound source. For optimal stereo imaging, consider the distance from the source and the desired ambient sound capture. Experiment with placement to achieve the best results for your specific recording environment.

4. Maintenance

4.1 Cleaning

• Always disconnect the microphone from power before cleaning.
• Wipe the microphone body with a soft, dry cloth.
• Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the microphone's finish or internal components.
• The foam windshield can be gently hand-washed with mild soap and water, then air-dried completely before re-use.

4.2 Storage

When not in use, store the SMX-100 in its custom carrying case to protect it from dust, moisture, and physical damage. Avoid storing the microphone in extreme temperatures or high humidity.
