About NTP Technology
Product Overview
NTP was founded in 1958. Since 2003 NTP Technology
has been a member of the Dan Technologies A/S group
of companies based in Denmark. NTP Technology
develops, manufactures and distributes professional high
reliability Audio I/O solutions and router infra structure
for analogue, digital and embedded audio routing
systems for major radio and television broadcasters
world wide.
The PENTA 720, PENTA 721 and PENTA 725 products
are Broadcast oriented modular I/O, router and
processing units with a focus on very reliable operation
and redundancy. The Penta products are designed for
use in television or radio studios, audio post production
facilities and outside broadcast vehicles. The Penta
products can be used in “stand-alone” configurations or
as units combined into a router system. The Penta
products are controlled via Ethernet by the various NTP
control software applications and general protocols.
In 2008 NTP Technology acquired the company DAD –
Digital Audio Denmark, a Danish manufacturer of highend Audio AD/DA converter interfaces, which formed
the NTP pro audio product line sold under the DAD
brand name.
Top quality, innovative technology and perfection in
performance are the reasons that NTP Technology has
been a preferred supplier for the broadcast industry for
more than 30 years. With a continuous focus on new
technologies, creative implementations and customer
needs, NTP Technology will continue to hold a significant
position also in the future landscape for audio I/O and
routing solutions.
With this approach NTP Technology provides smart I/O
and router solutions for any application, whether this is a
complex system for a broadcast studio facility, outside
broadcast unit, or a simple I/O solution for performing art
centres, concert halls or studio post production facilities.
NTP Technology’s team of application engineers provides
consultation on system configurations as well as training
and technical demonstrations.

PENTA Router Core
The Penta products have been designed with the
unique Penta router core based on a low latency and
a highly reliable FPGA-based asynchronous matrix
structure, with a time stamp mechanism providing
equal latency for all signals routed trough the Penta
core. The Penta core has a total capacity of 2,048 x
2,048 non blocking cross points, which provides a
capacity of 1,500 x 1,500 cross points on the I/O
level. All inputs and outputs have processing for level
adjustment, PPM level measurement, signal detection
and latency management. A part of the router core
also includes a 256 x 32 bus-based summing system.
AoIP via Dante / AES67
The PENTA 720 and PENTA 721 can optionally be fitted
with the robust tried-and-tested Dante™ AoIP digital
audio network technology, for routing and passing
signals via a Gigabit IP network. The protocol also
provides support for AES67 in compliance with current
standards. The Dante Audio format provides fast,
flexible, and cost efficient audio routing with an option
for redundant operation via IP. The NTP Dante system is
fully compatible with other Dante-enabled devices from
more than 200 manufacturers.
The Dante / AES67 AoIP routing provides low latency,
tightly synchronised transport of uncompressed audio
over Gigabit networks using off the shelf switches.
NTP Blue | NET Routing
The PENTA 720, PENTA 721 and PENTA 725 products
can form a routing system with distributed I/O
functionality for signal distribution and routing in
broadcast and other media related facilities. The NTP
Blue | NET router control system is based on the NTP
RCCore router control system and enables control of the
signal routing via a LAN / IP Ethernet based network
structure.
PENTA 720
I/O unit and 1.5K router engine
Features
Technology Overview
The PENTA 720 base unit comes as
standard with the following digital
interfaces:
The Penta 720 is based on a router core with a non-blocking 1,500 x
1,500 I/O matrix, channel based processing functionality and a
common signal summing processor. The matrix provides fixed latency
routing of all inputs to one or more outputs with a latency of 5 audio
samples and supports sample rates from 44.1 to 384kHz.
• 8 AES3 I/O interface via 2 D25
connectors
• 1 MADI I/O coax interface via BNC
connectors
• 2 interface for Pro Tools™ via SDR
connectors
The channel processor provides a signal detection logic, PPM level
measurement as well as level control on all input and output
channels. The common signal summing processor has a capacity of
32 mono summing output busses with a total of 256 inputs each
with an individual level control.
In addition to this, the base unit can be
expanded with the following factoryinstalled options:
Ethernet Control and Dante / AES67 I/O
• 64 ch. Dante/AES67 AoIP I/O via
RJ45 connectors
• Two Dual SFP MADI input/output mini

Control and interface via Ethernet
The PENTA 720 is controlled and monitored via a network
interface. Control protocols include NTP’s own protocol as
well as Pro Bel and Ember+. The PENTA 720 can be
controlled by multiple controllers simultaneously.
The two network connectors on the back of the PENTA
720 are also used for the optional Dante /AES67 AoIP
interface. The two ports can be configured as either
switched ports for daisy-chaining multiple units or as
redundant ports for the Dante/AES67 connections.
NTP Hotlink
NTP Hotlink is a digital audio format which provides 128 channels at 48 kHz sample rate on an optical fibre. NTP
Hotlink is an ideal solution for high-capacity links between multiple Penta units. All SFP slots in the Penta units can be
configured for either MADI or Hotlink operation.
Technical Overview

Control
Operation and Configuration
The Penta products are controlled via a standard network connection. The Penta products all communicate via the
NTP Penta protocol and the PENTA 720 and PENTA 721 also support the Pro-Bel SW-P-08 and Ember+ protocols. NTP
offers a range of application programmes for the configuration and management of the Penta units, including the Penta
manager (PENTAman) and DAD manager (DADman) as well as the NTP Router control systems, RCCoreV4 and Blue | NET.
PPM Signal
Monitoring
Penta Manager, PENTAman
The Penta manager control software runs on
Microsoft Windows. PENTAman is a stand-alone
user application for complete configuration and
operation of the Penta 720/721 interfaces. More
Penta units can be controlled by the application.
The PPM signal
monitoring
software runs on
Microsoft Window
as a stand-alone
application for
configuration,
display and
monitoring of input
and output signal
levels of one or
more Penta units.
Operation via a control system
The Penta products can be used and operated in systems managed
by a control system. The control system can be the NTP RCCore or
the Blue | NET control system, or a 3rd party control system
supporting either the NTP Penta command protocol or the industry
standard Pro-Bel SW-P-08 or Ember+ protocols.
VMC 2 – Blue | NET control
When using VMC 2 and the NTP Blue | NET Control System, it is
possible to establish an overall management of signal routing for all
the Penta units and other Dante-enabled AoIP units, with an IP
network as the back-bone for the signal distribution. The management
of the system layout is done by the control system with a system
database configured to have all information of the system. When
using the Penta products configured with a central MADI router the
NTP RCCore control system can be used for controlling a similar way
to the Blue | Net system. User operation of the control system can
be done via various VMC client software applications like the VMC 2.
DAD Manager, DADman
The DADman control software runs on Microsoft
Windows and Apple OS X. DADman is a standalone user application for complete configuration
and operation of the DAD products as well as
the PENTA 720/721 interfaces. DADman can
manage multiple Penta units and Penta units
can be controlled simultaneously from multiple
computers running DADman.
