JK Audio CELLTAP4C CellTap 4C Wireless Phone Audio Tap Adapter

Phone Call Recording Adapter for Interviews and Archiving

The JK Audio CellTap 4C is a passive phone tap adapter designed for recording high-quality audio from phone calls. By connecting to the 3.5mm headphone jack of a mobile phone, this device makes it simple to capture conversations directly into a recorder or mixer. Whether for interviews, journalism, podcasts, or archival purposes, the CellTap 4C provides an easy and reliable way to integrate phone audio into professional workflows.

Simple Setup with Standard 3.5mm Connections

The adapter uses standard 3.5mm TRRS connections to interface with both a phone and a headset, ensuring compatibility with most smartphones and mobile devices that include a headphone port. By plugging the phone into the designated input and connecting a TRRS-compatible headset, users can maintain a live conversation while simultaneously routing the audio to a recording system.

Stereo Recording with Transformer Coupled Output

The CellTap 4C delivers a stereo output that separates the microphone audio onto the left channel and the caller’s audio onto the right channel. This signal routing allows for independent mixing and editing in post-production, making it particularly useful for podcasters, broadcasters, and content creators who need clean separation between interviewer and guest audio.

Caller Level Adjustment for Consistent Sound

An integrated screwdriver adjustment lets users fine-tune the caller’s audio level to achieve a balanced recording. This feature ensures clear and consistent sound quality, even when dealing with callers on varying mobile networks or devices. The ability to adjust levels at the hardware stage reduces the need for heavy post-processing.

No Power Required for Operation

As a passive device, the CellTap 4C requires no batteries or external power supply. This makes it both dependable and convenient, as it can be deployed in field environments without worrying about charging or power management. Its simplicity and reliability make it a go-to tool for professionals who need consistent results.

Compact Build Made for Professional Use

Built with durability in mind, the CellTap 4C is compact, rugged, and made in the USA. Its sturdy design ensures it will hold up under frequent use in broadcast studios, on location, or in mobile recording setups. For those who need dependable call recording hardware without unnecessary complexity, the CellTap 4C delivers an efficient and professional solution.
