2U standard 19-inch rack-mount structure, featuring a black anodized aluminum brushed panel and humanized handles. Advanced titanium gold polishing technology is adopted, endowing it with an exquisite and premium finish.

★Computer Software: Complimentary computer programming software is provided with the product. Boasting a clear interface, the software is simple, easy to learn and highly practical, requiring no professional training (basic computer operation skills are sufficient). It enables the setting, modification, query and deletion of program elements including broadcast content, time, date and zoning (supporting both single program deletion and full deletion), as well as the backup of multiple sets of programmed programs.

Wireless Transmission: Adopts a U-disk based wireless data transmission method for connecting the computer and the device, which transfers computer-programmed timed programs to the device via U-disk. Auto/Manual mode is selectable; in Auto mode, the device operates programs automatically for unattended running.

Intuitive Display: Equipped with a 128×64 large-screen LCD with full Chinese menu and multi-level menu operation for easy operation.

★Power Management: Three-way power sockets are controlled by computer programming for timed on/off, which schedules the timed startup/shutdown of electrical equipment such as power amplifiers, CD players, DVD players and double cassette decks. The device is configured with one constant-on power output channel and one controlled low-level output channel; the latter can externally control a 16-channel programmable power manager for real-time on/off, and manage the real-time or timed power on/off of power amplifiers and other peripheral devices connected to the power manager.

Multi-channel Signals: Audio signals support 8-zone programmed timed output, and can also receive amplified signals from power amplifiers to realize the 8-zone programmed timed output of the controller.Priority Order: Emergency Announcement, Alarm Activation (or Timed Activation, priority selectable via settings) > Timed Playback > Manual Playback (including MP3, FM, AM, LINEOUT, etc.).

★1-channel Alarm/Timed Activation Output.

Zoned Paging: 1-channel volume-adjustable MIC input, supporting paging output to any of the 8 zones.

USB Interface: A USB port is designed on the panel, supporting hot-swappable U-disks.

★Advanced System: The built-in MP3 audio source outputs via 8 zones; two external audio source devices output audio after being powered on through the device’s POWER2/POWER3 ports, forming an 8-channel audio source output for 8 power amplifiers.

All electrical equipment is powered by the OBT-8080 externally controlled by the OBT-9300USB, constructing a powerful synchronous multi-audio-source public address system.
