Product Details
The MAGIC AC1 Go is a compact stereo IP audio codec that provides an additional independent command channel via G.711/G.722.
The system can be used for AoIP dial-up connections or IP leased lines. In AoIP mode, the system can register with 5 different SIP servers. For outgoing calls, the respective SIP server can be selected, incoming calls can be accepted automatically.
For reliable audio connections, Secure Streaming is integrated to guarantee highly reliable transmission by means of redundant transmission. The streams can be transmitted with delay to avoid failure with of inaudible switching even in case of burst errors.
The system supports the coding algorithms G.711, G.722, ISO/MPEG Layer 2, Opus, FLAC and PCM 16/20/24 bit in the standard version.
Optionally, the audio codecs can be extended with MPEG Layer 3, AAC-LD/AAC-ELD and AAC-LC+V1/V2.
The audio programmes can be input or output via an analogue or digital stereo interface (switchable).
The unit has an Ethernet interface with VLAN support for control and IP audio transmission.
Two RS232 interfaces are available for additional data and for control purposes. 4 TTL-GPIOs and 2 relays can be used for signalling.
The system also supports the Ember+ and DHD SetLogic protocols to exchange control and signalling commands with e.g. mixing consoles via 64 virtual GPIOs. Accessing status information and triggering of functions in the unit is possible via Ember+.
The system can be integrated into a network management system via the integrated SNMP protocol.
MAGIC AC1 Go is designed as a ½ x 19" system with external power supply.
The audio codec can be controlled via the front keypad with display or with the Windows PC software included in the delivery, with up to 5 workplaces being able to access a system simultaneously.
Multiple systems can also be centrally managed, operated and monitored via the Multi-Control software, which is also included.
The transmit and receive levels of all transmitted or received audio channels are displayed, including general system information such as IP addresses and alarms.
The internal system log file allows tracking of errors even without a connected PC and can be downloaded from the system at any time via the management software and displayed in an easily understandable way. For date and time information, the system supports NTP synchronisation.
Monitoring and alarming can also be done via SNMP. Traps can be reported to up to four network management systems.
Options
Coding Algorithms
In addition to the coding algorithms supported by default, the ISO/MPEG Layer 3 Upgrade, the FhG AAC-LD/ELD, the AAC-LC and the HE-AACV1/V2 Upgrade are optionally available via software upgrades.
AES67 4-Channel Upgrade
The AES67 upgrade allows the use of four additional audio channels (4 x RX (2 streams) and 4 x TX (1 stream)) over IP using AES67.
AES67 is the lowest common denominator of several similar technologies and thus secures the communication between e.g. AES67-compatible Dante® and Ravenna devices.
MAGIC System Manager Upgrade
If a broadcasting organisation has several AVT telephone hybrids and audio codecs, these can be viewed in the MAGIC System Manager. This centralised management software provides a clear overview of all MAGIC TH1Go, MAGIC TH2plus, MAGIC TH6, MAGIC THipPro Lite, MAGIC THipPro, MAGIC AC1 Go and MAGIC ACip3 systems. Even if systems use different software versions, all devices are supported. Any alarms and the operating status (in use, in configuration) are displayed for each device. Queries are made periodically via SNMP. System Monitor, Registration Dialogue, System Panel and Firmware Download can be accessed.
All hybrids and codecs can also be configured remotely by an administrator. Complete remote configuration of the system is possible and all presets and super presets can be managed. As a safety feature, the current status of the line is displayed. In future, desired systems will also be selected and then a new release will be rolled out completely to the corresponding clients and systems. Reconfiguration is also planned, either manually or via a scheduler. Presets and super presets can thus be loaded quickly and easily, and SIP accounts can also be assigned or changed.
One MAGIC System Manager licence is required per system.
