Reliable dual-line solution

We have deployed five of these units across our team. They run stable for weeks without needing a reboot. The ability to record two distinct lines into separate files automatically saves us hours of editing time.

Great SDK for custom integration

As a developer, I was looking for hardware that supports secondary audio development. The provided SDK made it easy to integrate recording triggers directly into our custom CRM software. Highly recommended for tech-savvy users.

Solid performance, clear audio

The audio quality is crisp and clear on both computer and telephone inputs. Setup took about 15 minutes. The only reason for 4 stars is that the manual could be more detailed regarding the Linux drivers.

Perfect for our office phone lines

We needed a reliable way to record both our main line and a dedicated support line simultaneously. This box handles both channels without any cross-talk. The pop-up display is a nice touch for quick status checks.

Good value for the features

Works exactly as described for my home office setup connecting my laptop and landline. The pop-up display is bright and easy to read. Wish it came with a longer USB cable, but that's a minor issue.

Excellent sampling rate

Impressed by the 48kHz sampling rate at this price point. The recordings are detailed enough for transcription services we use. The build quality feels durable and professional.

5 FAQ

Q: Does the pop-up display show the remaining storage space?

A: Yes, the pop-up LCD screen displays real-time information including recording status, active channel indicators, current time, and available storage space on the connected drive.

Q: Can this device record a VoIP call on one channel and a standard landline on the other simultaneously?

A: Yes, the 2-Channel Recording Box is designed to handle mixed input types. You can connect one channel to your computer for VoIP and the other to a physical telephone line, recording both independently at the same time.

Q: Can I save recordings directly to a network drive?

A: The device writes directly to locally connected USB storage. To save to a network drive, you would need to use the provided software or your custom SDK script to move files from the local buffer to the network location automatically.

Q: What happens if the power goes out during a recording?

A: The device is designed to safely finalize the current audio file in the event of a sudden power loss to prevent file corruption. However, we recommend using a UPS for critical continuous recording environments.

Q: Is the SDK compatible with Python for custom scripting?

A: Absolutely. Our Secondary Audio Development Support includes libraries and documentation for Python, C++, and C#, allowing you to create custom scripts for automated recording management.
