SF-NH1 The interface unit shall provide two (Left and Right) unbalanced analog amplified headphone output channels on a front-panel 3.5 mm Mini-jack. A rotary output level control shall be provided on the front panel. The maximum output level shall be referenced to 0 dBFS = 150 mW into 100 Ohms. The outputs shall provide a noise floor better than 95 dB below maximum output level from 20 Hz to 20 kHz, with crosstalk better than -80 dB at 1 kHz. The output shall provide a low-impedance path from the shield to the chassis. The unit shall be constructed in a steel enclosure equipped for mounting to any flat surface and compatible with RDL SysFlex mounting accessories. Digital to Analog conversion shall be performed at 24 bits with selectable sample rates of 44.1 kHz, 48 kHz, 88.2 kHz or 96 kHz. The unit shall operate from IEEE 802.3af compliant PoE power provided through the Ethernet cable. The unit shall be covered by a 3 year factory warranty. The Dante interface shall be an RDL SF-NH1.
