Williams AV MIC 168 – Heavy-Duty Dual-Muff Headset Microphone

Product Overview

The Williams AV MIC 168 is a heavy-duty, dual-muff headset microphone built for the Digi-Wave DLT 400 transceiver, combining a unidirectional electret boom microphone with circumaural noise-reducing earphones. It is the headset of choice for simultaneous interpretation, plant tours, and two-way communication in high-noise environments where interpreters and tour guides need to hear program audio clearly while speaking. The package pairs the proven MIC 068 headset with the ADP 016 y-splitter adapter, allowing both the microphone and headphone connections to interface with a single DLT 400 transceiver. With a 20 dB noise reduction rating and soft leatherette ear cushions, it supports extended wear during all-day assignments.

Product Description

The MIC 168 addresses a common problem in industrial guided tour and language interpretation deployments: ambient noise overwhelming both the talker's voice pickup and the listener's program audio. The dual-muff design seals around both ears with a 20 dB noise reduction rating, so interpreters working from a booth or guides walking a factory floor can monitor the floor feed or interpretation channel without raising volume to unsafe levels. The unidirectional electret microphone element rejects off-axis sound, keeping the transmitted signal focused on the wearer's voice rather than machinery, HVAC, or crowd noise.

Electrically, the microphone presents 1 kΩ impedance with -42 dB sensitivity and operates on 2–10 VDC bias supplied by the host transceiver. The headphone drivers offer 35 Ω impedance and a full 20 Hz – 20 kHz frequency response, giving wearers natural-sounding monitor audio for long sessions. Termination is via dual 3.5 mm stereo TRS plugs on a 39-inch cable, with the included ADP 016 y-splitter combining both connections into the single TRRS headset jack on the Digi-Wave DLT 400 transceiver. The headset weighs 0.75 lbs and is CE and RoHS compliant.

For AV integrators specifying Digi-Wave 400 Series systems for interpretation, intercom, or guided tour applications, the MIC 168 is the standard heavy-duty headset accessory for talker positions in loud spaces. Quieter installations can use the lighter MIC 158 dual-muff headset, while hard-hat environments call for the MIC 188.

Frequently Asked Questions

Which Williams AV transceivers is the MIC 168 compatible with?

The MIC 168 is designed for use with the Digi-Wave DLT 400 transceiver only. The included ADP 016 y-splitter adapts the headset's dual 3.5 mm TRS plugs to the DLT 400's single headset jack.

How does the MIC 168 differ from the MIC 068?

The MIC 168 is the MIC 068 headset bundled with the ADP 016 y-splitter adapter required for the DLT 400 transceiver. If you are connecting to an IC-2 interpreter console or a legacy DLT 300 with separate mic and headphone jacks, the standalone MIC 068 is the correct choice.

Is the MIC 168 suitable for noisy industrial environments?

Yes. The dual-muff design carries a 20 dB noise reduction rating and the unidirectional electret element rejects off-axis noise, making it well suited to plant tours, manufacturing floors, and other high-noise guided tour deployments.

Can interpreters use the MIC 168 for full-duplex communication?

Yes. Paired with a Digi-Wave DLT 400 transceiver, the MIC 168 supports simultaneous talk and listen, which is essential for interpretation, intercom, and two-way tour guide workflows.

What warranty and support does this headset carry?

The MIC 168 carries a 90-day Williams AV manufacturer warranty. Creation Networks can assist with Digi-Wave system design, accessory selection, and post-sale support for commercial deployments.
