USB devices

Our Echo USB Voice Recording devices provide powerful features for building small to medium channel count portable Digital Voice Recorders. Each model features a USB 2.0 compatible high throughput interface and combines a compact form factor with very low power consumption resulting in unmatched reliability.

On-board DSPs and large streaming buffers impose very little demand on system and application resources.

D-channel signalling supports Call Setup, Connect, Clear, DDI number and CLI number decoding.

It also supports all major ISDN variants, Q.SIG, DASS-2, DPNSS and various PBX Digital handset D-channel protocols. This means that simultaneous recording on all channels of both upstream and downstream sides of a conversation is possible.
