Multi-channel audio and telephone recording

The SEL DTR module includes the following devices:

• SEL DTR - PCI boards for logging audio information from analogue telephone lines, linear (microphone) and differential (radios) inputs. 
• SEL DTR USB - external device connected via USB port forloging audio information from analogue telephone lines, linear (microphone) and differential (radios) inputs.
• SEL DTR NET - IP network device for logging audio information from analogue telephone lines, linear (microphone) and differential (radios) inputs.

SEL DTR USB devices are designed to capture audio information from analogue telephone lines, differential and linear inputs (radios and microphones). Two analogue telephone lines and two analogue inputs can be connected to one device. The SEL DTR USB device can be connected to a a laptop, as well as normal PC. The selection of the required signal sources is made via software. .

External IP network modules SEL DTR NET are designed to capture the information from analogue telephone lines, differential (radios) and linear (microphone) inputs and to transmit it over TCP/IP to remote computer.
