The Net-Log has been specifically designed for long-term recording and archiving through the use of a dedicated hardware recording platform with a simple network connection for audio playback. The playback software on a network-connected PC streams the audio to the desktop where it can be played or saved as a file. The Sonifex Net-Log is a 4-channel audio recorder that can record weeks of programming on a large internal hard drive. The unit has been designed as dedicated hardware for reliability reasons, i.e. there is no PC motherboard in this machine. While PC-based systems are excellent for playback, they are generally not robust enough for continuous 24/7 recording all year round. The Net-Log has been designed from the ground up to offer: - High reliability for continuous operation. - High audio quality (mpeg compression). - Compatibility with existing and Windows-based broadcast systems (bwf files can be saved). - Automatic operation with very easy-to-use software. All audio files created by Net-Log are compatible with Windows Media Player™, so files can be emailed to colleagues and clients and played on any PC with an audio system. There are many applications for Net-Log, from radio stations recording their broadcasts for regulatory purposes, to small call centres, law firms and security companies using them for monitoring. Net-Logs have been installed in courtrooms and police interrogation rooms for audio monitoring. Radio Broadcast Recording When recording is required by authorities, Net-Log offers a perfect, easy-to-use and elegant solution, allowing playback of requested recordings within seconds. But even if recording is not regulatory, Net-Log can still deliver audio to anyone's desktop in a radio station - you don't need to go to the rack room or central technical area to play back a previously made recording. It therefore has the following advantages: - From their office, the sales team can check that advertising was broadcast on time and can create audio files to email to clients. - Programme controllers can spy on their presenters, check their performance and ensure that programmed music was broadcast. - Station managers can check their competition and compare it to the sound of their own station. - The production team has much easier access to audio recordings of past radio shows for preparing future jingles and trailers. Net-Log records in mpeg layer 2, the standard for broadcasting, so you can be sure that audio files created with Net-Log are compatible with almost all mpeg-based automation systems available. File downloads can be made in mp2, mp3 or linear wav format, and broadcast wave format (bwf) files are supported as standard, ensuring close integration with your broadcast systems. Key Features of Net-Log - Dedicated and reliable multi-channel recording hardware. - Easy-to-use remote Windows™ operation for playback, archiving, streaming and configuration. - Independently configurable channel pairs to record at different sample rates, different bit rates and in mono or stereo. - Configure channel recording duration as needed, e.g. 2 channels of low quality recording for 12 months with two channels of high quality recording for 1 month, on a single machine. - Recording inputs can be remotely controlled, e.g. covert recording from the live-mic output of a mixing console. - Automated voice recording - each channel can start and stop recording automatically by setting audio threshold levels, meaning it can be used for voice-controlled systems and telephone recording. - Up to 250,000 recordings can be made per channel. - Each Net-Log has its own IP address, so multiple machines can be installed on the same network. - Fail-safe alarm indicators and remote controls. - Password protection and system security access rights. - Support for hard drives up to 2048 GB. - Recordings can be made using the optional G.729 algorithm, allowing for longer recordings and reduced network traffic. G.729 audio quality is comparable to MPEG L2 at 32 kbps when used for recording/playing speech. - Recording on Net-Log can be serially controlled by Crestron and Televic meeting room controllers. Hardware Description Net-Log is a 1U rack-mountable unit that has 4 mono recording inputs on 3-pin XLR sockets with potentiometer gain controls and LED level indicators for each input. These accept 2 stereo or 4 mono audio streams which are encoded in mpeg layer 2 format and written to a large internal IDE hard drive. The disk size is continuously increased as technology improves and Net-Log can support sizes up to 2048 GB. Contact [email protected] for currently installed disk sizes. Net-Log has 2 serial ports on 9-pin D-sub connectors which are used to program the machine's IP address and to download new software. Additionally, there is a 15-pin D-sub connector used for remote input recording control and for alarm outputs (hard drive failure and archiving warning). A 10Mbps RJ45 network port is used to connect Net-Log to your PC network and audio is streamed using TCP/IP. Audio can be streamed simultaneously to one or more PCs, while simultaneously archiving audio data to an IP server automatically in the background. All Net-Log configuration and operational features are controlled from a connected PC using the Net-Log-Win software.
