Streamlined Connectivity for Your Hear Back PRO Hub
With the Hear Technologies Hear Back PRO Analog Input Interface Card, you can connect your Hear Back PRO Hub to any professional analog audio equipment. This option card provides eight balanced audio inputs, using a standard TASCAM DA-88-style pinout on a DB-25 connector. Furthermore, it includes a -10dB pad on each channel, enabling you to select a +8dB or +18dB maximum input sensitivity level. Meanwhile, it supports user-configurable sampling rates of 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz using jumpers. You can populate each Hear Back PRO Hub with two cards, outfitting it with 16 analog inputs, and you can populate your Hub with four cards to allow A/B input switching between two 16-channel banks. At Sweetwater, we recommend the Hear Back PRO Analog Input Interface Card to those seeking streamlined analog connectivity for their Hear Back PRO system.
