Overview

The Sennheiser ew 112P G4 is an all-in-one UHF wireless lavalier system designed for single-camera ENG, broadcast journalism, and field production where a clean, reliable dialogue signal is required without the complexity of a dedicated audio bag rig. The system pairs a camera-shoe-mounted receiver with the ME 2-II omnidirectional condenser lavalier microphone, transmitting up to 100 meters (330 feet) over a UHF link that accesses up to 3,520 selectable frequencies within its band. Sennheiser's G4 platform uses an analog compander to maintain a noise floor appropriate for broadcast dialogue — the characteristic sound is clean and intelligible, with the subtle artifacts of analog companding that experienced ears recognize on quiet dialogue passages. The 25 Hz to 18 kHz frequency response captures the full vocal range without coloration.

In the field, the ew 112P G4 earns its reputation on ease-of-use and reliability. The 3.5mm output connects directly to a camera's microphone input, keeping the signal chain short. Eight hours of battery operation covers a full shooting day without forced breaks for battery changes. The all-in-one camera-mount form factor is the defining practical advantage — there is no secondary piece of equipment to track, no bag to carry, no mixer to configure. This is a lavalier system designed for run-and-gun workflows where the operator needs broadcast-quality audio out of a single-camera setup. The Renewed designation on this unit means it has been inspected to Sennheiser's specifications and carries a 6-month Alto Music Warranty — a practical choice for operators who want G4 reliability at a reduced entry cost.

Frequently Asked Questions

The ew 112P G4 is listed as "Renewed" — what does that mean for reliability in professional field use?

This unit carries a 6-month Alto Music Warranty, meaning it has been inspected and certified to function within specification. For non-mission-critical field production work, a certified Renewed unit is a reasonable cost-saving choice. For broadcast work where a single failed take is unacceptable, consider whether you'd want a full manufacturer warranty — and build in a confidence-check session before any critical production day.

What frequency band does this G4 unit operate in, and does it conflict with common wireless audio systems?

The product listing does not specify the exact frequency band of this unit. Sennheiser G4 systems are sold in multiple frequency ranges (A, A1, AW, G, etc.) covering different portions of the UHF spectrum. Verify the specific frequency band of this unit before purchase and cross-reference with your market's RF allocation — the 600 MHz band was reallocated in North America and some units in that range are no longer legally usable.

How does the ME 2-II lavalier's omnidirectional polar pattern affect placement and performance?

The ME 2-II is omni-directional, meaning it captures sound equally from all directions at its capsule. In practice for speech, omni lavs are more forgiving of placement imprecision than cardioid lavs — you don't need to point them precisely at the speaker's mouth. They also handle off-axis talent movement (turning head, looking away) with less level variation. The trade-off is reduced rejection of ambient noise compared to a directional lav.

What is the actual dynamic range and frequency response of this system for dialogue recording?

Sennheiser G4 systems deliver broadcast-quality audio across a 25 Hz to 18 kHz frequency response. The system uses an analog compander (compressor-expander) that can introduce a subtle noise signature compared to digital wireless systems. For dialogue and speech applications — ENG, interviews, broadcast — the noise floor is well within acceptable broadcast standards; for music recording or extremely quiet productions, a digital wireless system like the Sennheiser EW-D would be preferable.

Can the ew 112P G4 receiver be mounted on a camera hot shoe, and what camera connection does it use?

The ew 112P G4 is an all-in-one system where the receiver mounts directly on a camera or recorder via a camera-shoe mount. The output connection is a 3.5mm jack, which connects to a camera's microphone input. This is not an XLR system — use a 3.5mm-to-XLR adapter if connecting to a professional audio recorder or mixer. The 3.5mm output is designed for direct camera mounting workflows.

Strengths & Trade-offs

👍 Pros

The ME 2-II omni lavalier's omnidirectional polar pattern is forgiving of imprecise clip placement and talent head movement — reducing dialogue inconsistency during ENG and interview work.
Up to 8 hours of operation on a single battery charge supports a full day of ENG or event recording without mid-shoot battery management.
100-meter (330-foot) operational range provides meaningful working distance for field production where talent moves freely within an exterior location.
All-in-one camera-mount receiver design eliminates the need for a separate mixer or bag — the signal chain from lavalier to camera runs through a single unit.
The G4 platform's 3520 selectable frequencies within its band provide enough channel headroom to resolve most frequency conflict situations on a busy multi-system set.

👎 Cons

Analog compander circuitry introduces a subtle noise signature that is characteristic of the G4 system — audible as a slight noise floor modulation on very quiet dialogue, particularly noticeable in quiet production environments.
3.5mm output is not a balanced XLR signal — connecting to professional recorders or mixers requires an adapter and accepts the noise risk of an unbalanced line run.
As a Renewed unit with a 6-month third-party warranty rather than a full Sennheiser manufacturer warranty, the reliability confidence window for professional broadcast deployment is shorter than a new unit.
The frequency band of this specific unit is not confirmed in product documentation — buyers must verify band allocation and regional RF legality before purchase and deployment.
The compact all-in-one form factor, while convenient for single-camera ENG, does not rack-mount or integrate with a proper bag-based audio system without adapters and workarounds.
