AoIP Products - PTP Grandmaster Clock
AVN-GMCS IEEE1588 PTP Grandmaster Clock with GPS Receiver
Category: Audio Over IP Products. Product Function: Provides a PTP time synchronised clock for use with AoIP audio networks. Typical Applications: Synchronise a PTP AoIP network, provide a GPS referenced signal via AES-3id, provide a master wordclock studio output or distribute a reference frequency to T&M equipment via the PPS output.
Sonifex joined the Ravenna group in 2012 and the AVN-GMCS is the result of our R&D in the area of audio over IP. 2
Features: • GPS enabled, with master and slave modes. • 8ns PTPv2 time stamping resolution. • Holdover drift <1ppm, with options for <0.01ppm & <0.0005ppm. • AES-3id, wordclock & variable PPS outputs. • Analogue master input. • Dual power supply inputs. • Front panel display. • GPS sync and power supply present LED indicators. • Ethernet webserver and front panel control & configuration.
* This figure represents the holdover accuracy should the GPS signal be lost - this is an approximation based on 1st year stability figures.
The AVN-GMCS is a PTPv2 grandmaster clock for use with AoIP applications. IEEE15882008 PTPv2 (precision time protocol) is used to synchronise all the nodes within a network. To achieve this one of the nodes must become the master clock and distribute time packets to the others. The AVN-GMCS is designed to perform this role simply and accurately, enabling sub micro second synchronisation between all nodes. RAVENNA (of which AES67 is a subset) allows for the distribution of audio across a network. For this to be possible, each of the nodes needs to be time synchronised with one another. Ravenna uses PTP time stamping to achieve this, which distributes the network time but also works out the latency involved in the delivery and adjusts the time at each node accordingly. Unit configuration is achieved easily either with the front panel controls or the webserver, including the setup of the PTP profile. In normal operaton, the unit has PTPv2 time stamping resolution to 8nsec. The AVNGMCS uses a combination of a GPS receiver, a PLL (phase lock loop) and a specialist on-board clock device to create the precise, low jitter clock signals required to drive
the physical transceiver’s time stamping circuitry, also providing holdover if the GPS signal is lost. The specialist on board clock is available in three different types: TCXO, OXCO and CSAC (Chip Scale Atomic Clock, Caesium), which vary in both price and accuracy: AVN-GMCS – TCXO Temperature Compensated Oscillator accurate to 1 part per million (worst case 1 sec gain/loss every 11.5 days). * AVN-GMCOS – OCXO Oven Controlled Oscillator accurate to 0.01 parts per million (worst case 1 sec gain/loss every 3.1 years). * AVN-GMCCS – SAC Quantum Atomic Clock accurate to 0.00050 parts per million (worst case 1 sec gain/loss every 63 years). *
AoIP Products - PTP Grandmaster Clock Specification For AVN-GMC Timing Specification
A separate clock input can act as an alternative reference source to GPS. Clock outputs, driven from the physical transceiver, can be used to provide media clocks for external equipment local to the AVN-GMC when it is in both ‘master’ and ‘slave’ states. The clock outputs are available as AES-3id and word clock at 32, 44.1, 48, 96, 176.4 and 192kHz. A variable PPS output is also available to provide an external clock accurate to the PTP system timing. The built-in webserver ,or front panel LCD display, can be used to configure the unit.
Front panel LEDs show the synchronisation status, GPS lock and the status of the AC and DC power supply inputs. 4 general purpose outputs indicate critical states for the unit using a 9 way D-type connector mounted on the rear panel. Pull down when active pins are supplied for GPS lock status, external sync present, AC power present and DC power present. The unit has a front panel power button and dual power connectors - an IEC mains input and a 12V DC input, which allows the
AVN-GMCS to be used for both studio and mobile installations. Moreover this allows for a secondary power source to reduce the effect of power down events. In any case, the unit monitors the status of both power sources and displays this on the front panel. In power off situations, a super capacitor is used to keep the GPS receiver powered in a low power mode for more than 20 hours, enabling the receiver to regain lock immediately rather than having to ‘cold’ start.

Audio & Video Interfaces - Synchronisers, Delays & Silence Detectors
RB-FS42 Audio Failover Switcher, 4 Main I/O, 2 Standby I/O
• Category: Synchronisers, Delays & Silence Detectors. Product Function: To route the source audio signals in to a standby encoder in event of encoder fail. Or to route the destination audio signals from a standby decoder in event of decoder fail. Typical Applications: As a failover switcher for multi channel audio transport over E1 or IP, typically as performed by APT Oslo, Prodys Nureus, where a N+1 topology is adopted. Features: • Relay based switching. • Dual DC, or AC, power supplies (select when ordering). • Encoder site (Set via IP): 4 stereo

Decoder Site (Set via IP): 4 +2 stereo program inputs, 4 program outputs where each program input carries: analogue L/R, stereo AES/EBU & RS232. Decoder Site: Each program input has an alarm detect GP input. AES/EBU transparent (for Dolby E transport). Passive throughput in event of power outage. GPO output for signalling RB-FS82 alarm conditions: PSU 1/2 fail, Standby 1/2 active, Summary Alarm. Automatic or Manual reversion modes. LED indicators on front panel. IP control, including Web GUI and SNMP.
The RB-FS42 4 + 2 audio failover switcher is a smaller channel count version of the RB-FS82, offering a lower number of inputs and outputs. It is a more cost effective solution where failover is needed for a smaller number of sources/destinations and supports all of the features of the RB-FS82.
Switching of program sources, including standby sources, to destinations in the event of source failure (‘Standbys to inputs’). Typically this would be audio decoders at a transmission site with “N” x programs and “N” x decoders feeding “N” x transmitters. If a decoder fails, the audio from a standby decoder, or other audio source such as an mp3 player, overrides the signal path to the transmitter so ensuring continuity on air.
The device has 4 main + 2 standby, stereo analogue audio, AES/EBU digital audio and RS232 connections (both inputs and outputs) The RB-FS42 supports any configuration and can be configured via Ethernet for two ŽĨƵƉƚŽϰŵĂŝŶƉƌŽŐƌĂŵƐŝŐŶĂůƉĂƚŚƐ;Eч main operational applications: 4) and there are 2 standby program signal For switching of program sources to a standby paths, in either mode of operation.

Typically this would analogue L/R audio, AES/EBU digital audio be audio encoders at a program distribution and RS232 data.

If an encoder fails the audio destined for that encoder gets routed to a All signal paths are passive and therefore standby encoder so ensuring the continuity of completely transparent utilising relay based audio to network transport. switching. This has the benefit of a “straight wire” topology during normal (alarm free) operation and also during any power outage to the device. An additional benefit of the passive signal path is AES/EBU bit transparency allowing throughput of AES/ EBU AC3 Dolby E TM signals. To ensure the passive nature of the device, switching is determined by alarm (General Purpose) inputs, with this alarm signalling in turn being normally provided by the encoder or decoders (or other devices) at site. Recognising the mission critical nature of the system, a high grade of relay is used in the RB-FS42.

The passive design ensures continuity of audio in the event of any power outage. However the RB-FS42 also includes dual redundant power supplies (85V-264V AC with a 12V 1A DC backup as standard). The RB-FS42-DC model accepts two DC power inputs (24 - 48V DC) via locking 2.5mm pin power connectors and both power supplies are monitored by the unit. This means that if either power supply fails, the other is ready to take over. In the extremely unlikely event that both fail, the unit’s passive signal path ensures a straight wire connection for all 4 program feeds (analogue, AES/EBU & RS232). This is essential for applications such as installation at transmitter sites, where a power failure to the unit will not prevent the audio input signal from being output to each of the supported 8 transmitters. A row of LEDs on the front panel confirm the unit status, with each individual program path indicated as being in alarm with either Standby 1 or Standby 2 programs clearly confirmed as actively over-riding the failed signal. Alarm LEDs on the front panel are also indicated for power supply 1 failure and power supply 2 failure and these are mirrored by the device’s own General Purpose Outputs so facilitating easy interfacing of the device with the addition of a summary alarm status GPO.
alarm is detected and if both Standby paths are already in use, then one of the two remaining options (Through, Silence) will be used. The unit can be configured to either Automatically restore a Main ‘through’ path or wait for a Manual button press. In the event of alarm clearing, the unit will automatically revert to normal operation, but a manual reversion mode is also provided, allowing for engineering investigation without the unit ‘hunting’ between different signal paths. Two buttons on the front panel, RESTORE 1 and RESTORE 2, allow manual restoration of the previously failed signal paths, away from Standby 1 and Standby 2 respectively. To facilitate integration with site management systems the RB-FS42 supports SNMP V1 and is configured by a simple web based GUI. All relevant information regarding input/output status, alarms and power supplies is available via SNMP GET requests to the unit. Traps can also be generated for most of the actions which can occur, including power supply fail and input GPI alarms, etc. Contact Sonifex for further information if you have a particular requirement that isn’t catered for by the RB-FS42 as standard.

The RB-AEC is an acoustic echo canceller primarily designed for the benefit of presenters and studio personnel in television and radio. When a studio presenter’s microphone signal is played out through a monitor speaker in the control room, it can be picked up by the control room microphone(s) and returned to the presenter’s earpiece as an undesirable echo.
It now has auto-sensing combined analogue and AES/EBU inputs and outputs, front panel speed dial buttons, together with an Ethernet interface to allow web browser access to the configuration and internal settings. All whilst still retaining stunning line balance rejection figures.
In circumstances where green screen video processing is taking place, the delay can be greater than 200ms. The RB-AEC is used to remove the control room monitor speaker output from the presenter’s feed by adapting to the environment in which the control room microphones are placed. Although acoustic echo cancellation is more commonly implemented in telephony systems, the Sonifex RB-AEC is designed to produce broadcast quality cancellation.
DHY-04G GSM Hybrid AES/EBU & Analogue I/O With Ethernet The DHY-04G is used on a quad band GSM cellular (mobile) phone network instead of a telephone (POTS) line. The DHY-04G can accept a SIM card in the rear panel slot and by connecting a suitable GSM antenna, it can receive and make high quality broadcast calls over the cellular network, converting the GSM call to the 4 wire audio signal to and from a connected mixing console. Ideal for studios in remote locations, for OB vans and trucks on the move, and in emergency situations where a telephone landline can’t be guaranteed, the DHY-04G offers outstanding performance.
