Overview
The SF-NH1 is a headphone amplifier that converts two Dante network audio channels to a stereo headphone output with front-panel level adjustment. The output connects through a stereo 3.5 mm Mini-jack. Each channel provides 100 mW into 100 ohms for a network digital audio level of 0 dBFS. Special software is not required to configure the module. The SF-NH1 is a professional grade product for studio quality fidelity and low noise performance.
The SF-NH1 is PoE powered. Valid PoE power and synchronization to the Dante network is indicated by a green LED visible from the front of the unit.
The SF-NH1 is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX® product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of SYSFLEX® products adds enormous flexibility in the design and installation of professional A/V systems.
