Model 234 Announcer’s Console

Order Code: M234

The Model 234 Announcer's Console is designed for on-air and live-event use by announcers and commentators who will benefit from high-performance microphone and headphone audio resources. Supports Dante audio-over-Etherent media networking technology and includes an extensive set of features. The compact tabletop unit uses the STcontroller software application for configuration. Five pushbutton switches allow the user to control five audio output channels: one main and four talkback. Two gigabit (GbE) Ethernet interfaces allow redundant Dante operation. Powered using a Power-over-Ethernet (PoE) connection or an external source of 12 Vdc.
