International: 408-573-1400Rane NM 1 Network Mic Preamp
Rane NM 1Network Mic Preamp is a very versatile single channel CobraNet I/O box that finds use in many applications. Rane NM 1 has a single studio-grade microphone input with +48 volt phantom power, and a single amplifier output for connection to an external loudspeaker. Rane NM 1 presents matchless features in a compact, reliable, easy to install and maintain package. Rane NM 1 design is based on the Cirrus Logic CS18101 CobraNet chip and CM-2 reference design including the secondary CobraNet port for data and power supply redundancy (more on this later). The microphone signal can be transmitted over CobraNet and the amplifier input can be driven by any CobraNet audio channel. Rane NM 1 also has logic I/O on a DB-15 connector for reading external switches and driving indicator LEDs so it can be connected to a custom switch panel to implement microphone enable, busy indication and similar functions.The feature of Power Over Ethernet (PoE) that adds the most versatility to Rane NM 1. It is fully compliant with the IEEE 802.3af standard as a Powered Device (PD). This means it's powered through the CAT 5 cable that connects it to an Ethernet switch. Of course, the Ethernet switch used must comply with the 802.3af standard as Power Supply Equipment (PSE); these switches are available from all the major Ethernet equipment manufacturers. All parameters are controllable via standard SNMP messages including microphone gain and muting, amplifier output level and muting, and CobraNet Audio channel and Bundle assignments. Four exterior switches assign the NM 1 MIB's SysName variable to uniquely identify each unit on the network. All NM 1 audio and data connectors are metal with locking, annular-ring shields for maximum durability, security and immunity from electromagnetic interference, be it radio, static or legislative hot airwaves. And all this fits in a very rugged (but good looking) extruded aluminum box. Rane's engineers have designed Rane NM 1 to have a redundant PoE supply along with the redundant data connections. Rane NM 1 can be powered from either Ethernet port independent of which one carries the CobraNet data, so an independently redundant power system comes along with the redundant data system with no redundant effort. Switching between ports for PoE is almost seamless and audio interruption is minimal. If the primary port fails the secondary port takes over very quickly, typically 10 ms, without loss of programmed settings. Features Power Over Ethernet (PoE) with built-in redundancy.
