DESCRIPTION

TERRA-AMPII comes with 20W x 2 Channels with 8 Ohm (or bridged to 40W x 1 CH with 4 ohm) amplifier outputs, 1 balanced mic/line input, 2 mono or 1 stereo line outputs and 1 stereo line input (3.5 mm mini-jack). A micro-SD card interface is provided for playback and backup of pre-recorded playlists and announcements. 3 control inputs can work with RAC 5/RAC 8 source selector and volume controller, event triggering such as call/hang up, music play/stop and 3rd party command, etc. And the 2 relay contact outputs can be programmed to control an external device. TERRA-AMPII is also an ideal IP solution for any applications that require a simple device to paging, full duplex intercom with AEC (Audio Echo Cancellation) and play streaming audio over network. The TERRA-AMPII is easily configured via web interface providing full control over features such as priority and event management, logic control, DSP control, scheduler and output levels, etc.
