RN 101 IO
Control SectionThe front-panel provides controls to set up and configure the unit without a computer. It incorporates three two-digit displays and
six push buttons that are used for intuitive operation of a two-level menu. Optionally, RockNet 100 can be remotely controlled using the RockWorks PC/Mac software via the USB interface. Default mode displays the status of the device when the system is in normal operation and shows:
• channel assignment for the input channels [quad 1 to 20]
• channel assignment for the output channels [quad 1 to 20]
• device ID [1 to 99]
A ‘quad' is a term used to describe a four channel block that simplifies the routing if no PC is used. The 80 transport channels are packaged into 20 quads.
Options mode gains access to the general device setup:
• select primary / secondary master
• shut-off display
• lock-out front panel operation
I/O Section
The RN.101.IO provides 16 microphone/line input and 8 line output channels on XLR connectors. The circuit design is optimized to maximize audio quality. The mic pres are similar to the highly acclaimed 300 series preamps and the converters characterized by high definition and wide dynamic range based on proprietary technology.
Any input channel of the RN.101.IO can be remotely controlled by a Yamaha mixing console or the RockWorks PC/Mac software:
• pre-amp gain adjustable between -6dB and +66dB in 1dB steps
• select 48V phantom power (with auto-mute)
• mute channel
The status of each input is displayed by four LEDs, indicating:
• mute [on/off]
• signal presence
• clip
• phantom power [on/off]
Each output channel can be controlled by the RockWorks software:
• output level adjustable between -9dBu and +24dBu in 1dB steps
• mute channel
The status is of each output is displayed by three LEDs, indicating:
• mute [on/off]
• signal presence
• clip
Network Interface
The network interface incorporates Media Numerics' proprietary core technologies. LateralTM ultra-low latency asynchronous transmission enables RockNet to support various redundant network topologies and to provide real-time, isochronous data transport in conjunction with remote control data. The data rate is 200 MBits/s on a CAT5 cable and the number of nodes is limited to 99. ConcreteTM clock recovery and jitter rejection utilizes a unique digital PLL structure. Jitter magnitude, spectrum and probability distribution are de-randomized by a sophisticated digital modulation scheme, resulting in an extremely high jitter rejection and zero jitter build-up through the network. Two Ethercon® RJ45 network connectors link to an upstream and a
downstream neighbor in a redundant ring topology.
