PENTA 721 is a new generation audio router and audio distribution interface from NTP Technology, which provides a versatile and flexible interface for signal distribution of digital audio via AES/EBU, MADI, Avid Pro Tools interface as well as routing via IP Gigabit Ethernet and optical fibre networks.
PENTA 721 is a compact 1U digital audio interface designed for stand-alone use in recording studios, radio stations and stage venues. It comes with eight channel AES/EBU input/output channels, MADI, two IP Audio Ethernet in/outs and an interface for Avid Pro Tools as well as a mini-module slot for ST optical MADI connection or dual SFP MADI optical in/out.
8 AES/EBU I/O and 1-3 MADI I/O
Interface for AVID Pro Tools
IP audio L3 Ethernet I/O powered by Dante
TCP/IP control via NTP Router Control System and
Stand alone control applications for PC
Single or Dual power supply
Flexible patching and routing of digital audio signals providing
Stand alone IP audio interface and format converter
Interface for NTP TDM router systems
Low latency, tightly synchronised, transport of uncompressed audio over IP networks using off the shelf switches
PENTA 721 include a 1024x1024 multiplexer,enabling all analogue and digital inputs and outputs to be routed in any combination; this enables the unit to also split signals for advanced signal distribution. The multiplexer can be used to establish the static connections of the signal inputs and outputs, and furthermore it incorporates soft switching with a fade down and fade up functionality of the signal level. Soft switching ensures that setting or changing a signal path can be made without any audible click or artefact.
IP Audio powered by Dante
The PENTA 721 IP Audio protocol is based on the robust tried-and-tested Dante™ digital audio network
technology, and will interoperate with products of other brands that comply with Dante. The protocol will provide AVB
support once standardization is fully completed. The Dante and NTP IP Audio formats provide fast, flexible, and
economical audio routing via IP and are compatible with NTP PENTA 720 Modular I/O, NTP PENTA 725 IP Audio router, and other Dante devices. The IP Audio routing provides Low latency, tightly synchronised, transport of uncompressed audio over Gigabit IP Ethernet Layer 3 networks using off the shelf switches, and routers for audio routing via one or more sub-nets. A total of 512 channels can be routed on a 1 Gigabit network, and more if the network capacity is higher.
PENTA 721 are TCP/IP controlled via one or two Ethernet ports. Control and supervision can be made by the NTP RCCore control system, and the operation is done via the NTP VMC control software client applications. A simple dedicated software control application for Windows is available for controlling and setting up PENTA 721 on a unit to unit basis when less advanced operation is required.
The IP Audio routing is for larger systems controlled by the NTP RCCore Router Control System, for easy and simple setting of connections on the Gigabit IP Ethernet. PENTA 721 can also be controlled by the Dante IP Audio routing controller software.
The ultimate choice for High Reliability and High Performance Audio Routing and Audio Processing.
Small in size, but big in performance. The all digital Penta 721 is developed with the newest technology in FPGA, SMD and software design. Featuring single or dual processor. Ultra compact, ultra fast, ultra reliable.
Reliability, innovation and years of expirience.
NTP IP Audio is powered by Dante.
