how to install Sennheiser SKM 100 G4-S Handheld Transmitter

To achieve optimal performance with your Sennheiser SKM 100 G4-S handheld transmitter, follow these straightforward steps. This process assumes you already have a compatible evolution wireless G4 receiver and microphone capsule selected for your needs.

Step 1: Insert fresh batteries. Open the battery compartment on the transmitter and place two AA batteries (alkaline or rechargeable NiMH) according to the polarity markings. Ensure the batteries are seated properly to avoid contact issues during performance.

Step 2: Attach your chosen capsule. If you are using a replaceable capsule such as e 835, e 935, or another compatible capsule, firmly attach it to the transmitter’s microphone head, ensuring a snug fit. Some capsules may require gentle threading or a snap-fit connection; follow the capsule’s installation instructions to secure it correctly.

Step 3: Power on and configure. Turn on the SKM 100 G4-S using the on/off switch. Verify that the mute switch is functioning and test the microphone by speaking into the capsule. If your system uses a dedicated gain or pad control, set these according to your mic technique and the performer’s voice.

Step 4: Sync with the receiver. Use IR sync to pair the transmitter with your evolution wireless G4 receiver. Align the IR window on the transmitter with the receiver’s IR sensor and initiate the sync command from the receiver. The devices should indicate a successful link, and you should see the corresponding channel and signal strength confirm on both units.

Step 5: Set the channel and level. Ensure the transmitter’s channel matches the receiver’s, then adjust the transmit level so your voice sits cleanly in the mix without clipping or excessive noise. Perform a quick sound check in a live environment to confirm consistent gain throughout your cueing and performance.

Step 6: Final checks and on-stage readiness. Confirm that the mute switch works as intended, and perform a final mic test with the performer’s typical vocal technique. If you anticipate feedback in the venue, consider adjusting the capsule choice or mic placement, and coordinate with the sound engineer on monitor levels and EQ to achieve a balanced, feedback-resistant mix.
