Pros & Cons
👍 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.
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.
