Overview
Audioscience ASI-2816-1000, AM/FM/Weather, 1RU 4 Channel Streaming Tuner
The ASI2816 is a multi-channel streaming radio tuner packaged in a 1U form factor. It can be configured with up to four modules. Each module contains four radio tuners for a total of up to 16 tuners per ASI2816.
PLEASE NOTE: THIS PART NUMBER ASI-2816-1000 IS PRECONFIGURED WITH 1) ASI2816 and 1) ASI1471 MODULE WITH FOUR AM/FM/WeatherBand (WB) tuners. PLEASE CONTACT US FOR OTHER CONFIGURATIONS.
The ASI1471 module contains four AM/FM/WeatherBand (WB) tuners. The ASI1472 module contains four AM/AM-HD/FM/FM-HD tuners. Up to sixteen ICY encoded audio streams can be sent from the ASI2816. The format of the streams is mono 44.1kHz AAC-LC.
The ASI2816 contains an OLED front panel display showing current configuration and status of all tuners including band, frequency, signal strength and HD status.
Each tuner module also includes balanced stereo audio outputs on a StudioHub compatible RJ-45 connector with a software adjustable level of 0 to +24dBu
