Audio and contact transmission device "SPF2154"

With the addition of units, transmission is possible for up to 32 points! You can also listen to the sine wave audio source.

The "SPF2154" is an IP conversion device that uses Ethernet (IP network) as its transmission medium to transmit voice signals and contact signals bidirectionally. It encodes voice signals and contact signals, transmits them as packet data, and demodulates the received packet data on the opposite side to output voice signals and contact signals. You can select the sampling frequency and compression format for the voice, allowing you to set the transmission bandwidth and audio quality as desired. 【Features】 ■ The voice channel transmits 2 channels of input and 2 channels of output bidirectionally. ■ It can transmit 16 contact signals bidirectionally (expandable to a maximum of 32 points with unit addition). ■ You can monitor the voice signals during transmission by selecting to listen to either the transmission or reception, or both, through the monitor speaker. ■ It is possible to listen to a sine wave audio source through local operation. ■ It has parameter setting functions, recording and playback level monitoring, and network configuration capabilities. *For more details, please refer to the PDF document or feel free to contact us.
