Hear Technologies Hear Back PRO Modular Mix Routing System with MADI Input (4-Pack)

The Hear Technologies Hear Back PRO Modular Mix Routing System with MADI Input (4-Pack) is a modular and expandable system designed for professional audio applications. It includes a MADI input connection, line level inputs with optimal settings of 0 dBu and maximum of +18 dBu, XLR mono balanced inputs with typical impedance of 150 ohms, and high pass filtering at 150 Hz. The system also features headphone load impedance of 8 ohms with 1.2 W, line outputs with a frequency response of 20 Hz to 20 KHz, and noise specifications of -93 dBu @ 192 kHz (A-Weighted). The system includes an analog input hub with 8 balanced inputs on a DB-25 female connector, maximum input levels of +8 dBu and +18 dBu, RJ45 hubs for HBus in and out, USB 2.0 ports for firmware and settings, and a card hub. Power requirements include 48 VDC at 150 Watts for the hub and 36-52 Volts DC at 15 Watts max for mixers via an external power supply. The mixer dimensions are 9.5 x 5.95 x 2.71 inches with a weight of 1.6 lb, while the hub measures 1.75 x 19 x 8.5 inches and weighs 6.3 lb.
