5 – ARCHITECTS & ENGINEERS SPECIFICATION
The CobraNet interface unit shall provide four mic/line analog inputs on rear panel pluggable 3-pin barrier strips.
Software selectable gains of 0dB, +25dB, +40dB, and software selectable +24V phantom power shall be provided. The
internal analog to digital signal conversion shall be performed at 16-, 20-, or 24-bit resolution with a sampling
frequency of 48kHz.. Two channels of balanced line-level outputs shall be provided on the rear panel pluggable barrier
strips. Outputs shall have software selectable gains of 0dB and +10dB. 7 logic inputs shall provide capability to
selectively mute various combinations of inputs and outputs. Interface power shall be provided by either an 802.3af
compliant PoE network switch or a +12VDC external power source.
The CobraNet interface shall provide DSP capabilities for independent channel gain, equalization, compression, and
gain sharing automatic mixing on all four local input channels. Each local output channel shall have DSP output limiting
capabilities. The DSP shall also provide a fully configurable 8-input, 2-output matrix mixer.
The CobraNet interface shall be compatible with Attero Tech Control Center software for flexible control and monitoring
in system applications. The CobraNet interface shall include a UL listed power source. The CobraNet interface shall be
compliant with RoHS directive.
The CobraNet interface shall be the Attero Tech DialogBox 4/2.
