[. . . ] Note: The top-most red LED should never illuminate during normal operation. Note 1: Audio specifications are measured from the input into the CAB 8i and the output out of the CAB 8o where relevant. Line level: 95 dBA, 93 dB unweighted, with a +12 dBu input signal, unity gain in and out* Two BNC I/O ports Note: Can be used for redundancy back-up that automaticaly switches from one CAB 8 to another if the first should fail. Better Than 65 dB at Any Gain Setting: 73 dB with +12 dBu input and unity gain in and out*, 69 dB with a +4 dBu input signal and unity gain in and out*, 68 dB with a Ð56 dBu input signal, no input pad, analog input gain at 60 dB, digital gain at 0 dB, analog output set for +12 dBu maximum (factory pre-set jumper for unity gain through-put). +29 dBu, with a 20 dB pad in and the analog input gain at 0 dB, +38 dBu with a 20 dB pad in and the analog input gain at Ð9 dB. Note: The analog input gain control is not buffered with an electronically balanced amplifier and maintains a balanced input circuit with 1-dB-per-step precision and specified CMRR. ¥ Eight with 20-bit transmission quantization selected ¥ Seven with 24-bit transmission quantization selected Audio specifications are measured with the input fed into the CAB 8i, digitally transmitted through an Ethernet hub, and the output fed out of the CAB 8o where relevant. CAB 8i: The Peavey CAB 8i shall provide eight channels of either microphone or line-level audio transmitted onto an Ethernet network. It shall provide full-bandwidth, high-quality audio transmission via 100BaseT (fast) Ethernet without lossy compression techniques, drop-outs or signal degradation by employing CobraNet audio transmission protocol to make Ethernet signal distribution deterministic. It shall employ 24-bit A/D converters with 20- or 24-bit selectable transmission quantization utilizing a 48 kHz sampling rate. It shall have a frequency response from 20 Hz to 20 kHz, +0/-0. CAB 8o: The Peavey CAB 8o shall provide eight channels of line-level audio transmitted from an Ethernet network. It shall provide full-bandwidth, high-quality audio transmission via 100BaseT (fast) Ethernet without lossy compression techniques, drop-outs or signal degradation by employing CobraNet audio transmission protocol to make Ethernet deterministic. It shall employ 24-bit A/D converters with 20- or 24-bit selectable transmission quantization utilizing a 48 kHz sampling rate. It shall have a frequency response from 20 Hz to 20 kHz, +0/-0. Its total harmonic distortion shall be no more than 0. Maximum output level shall be +24 dBu with a load of 600 ohms or greater. CAB 8o gain shall be from The output impedance of the CAB 8o shall be 100 ohms and designed to drive a load of 600 ohms or greater. Control features shall include eight relays with both normally open and normally closed contacts, and eight channels of TTL control outputs, both of which are software controllable via an Ethernet link. Also included are eight channels of analog voltage-control ports that allow external switches potentiometers or voltage sources to control MediaMatrix software parameters via an Ethernet link. Front-panel indicators shall display the following status conditions: signal transmission, signal reception, transmission error, reception error, fault indication, link indication, conductor status, RS-485 control indication, and power presence. It shall have eight peakreading headroom meters to monitor the analog level present at the output of the D/A converters, with the top-most red LED indicating D/A clipping. [. . . ] It shall have eight peakreading headroom meters to monitor the analog level present at the output of the D/A converters, with the top-most red LED indicating D/A clipping. Rear panel features shall include a detachable AC power cord, an AC power switch, and an AC power receptacle with a built-in auto-resetting circuit breaker. external or internal fuses shall not be acceptable. It shall have two word-clock connectors to enable auto-switch-over should a unit fail. [. . . ]
