With Eapt-X, OPUS, AAC HE
In its 15th year and 4th edition, the CENTAURI 3001 has become the broadcaster's darling. Everything onboard with even more to explore. Connects via Layer 3 or AAC, HE or ADPCM4SB, linear or G.722, and allows transmission sessions in mono or stereo.
It's all you need for a perfect transmission. Trust the classic version of an industry standard: the CENTAURI IV 3001. It supports SIP, DHCP, EBU Tech3326, and is a highly flexible codec algorithm tool box, supporting all relevant IP protocols including VoIP features. It offers wide compatibility, even with older 3rd party audio codecs from M-Taxi to Z-Fyre, featuring add-on capabilities for ISDN, X.21, Dual IP, Redundant PSU modules and more.

Backup options can be configured within one network or cross network, e.g. from IP to IP, from IP to ISDN, etc. depending on the available network interface cards.
Gateway functions allow the bridging of formats and interfaces, depending on availability of algorithms and network interface cards, e.g. from an 2x64kbps Layer 3 ISDN call into an Axia Livewire IP protocol
Simple Answering machine
Incoming calls can be recorded in different formats and kept on internal or external storage media, including SSD cards. They can also be send to external servers and disk capacities via FTP. The recorded signal can be incoming, outgoing or both.
Time logging is available as well, as an extension of the answering machine. Time stamps and further metadata archiving is as simple to admin as the audio format and storage organization.
Audio connections via IP are moving more and more to SIP as SIP servers are becoming more available. Multi SIP allows use of a variety of SIP servers within one product, e.g. 2 transmissions via SIP server 1, 4 transmissions via SIP server 2, etc.
Combination of applications and extensive applications packages
The CENTAURI IV 3001 can combine the above mentioned applications and do backup, gateway and recording/logging at the same time.
PLEC - Packet Loss Error Concealment
Real-time audio data streamed over unreliable IP networks, such as the Internet, may encounter losses due to dropped packets or late arrivals. PLEC detects and prevents dropped packets.
Voice Options (Echo Cancellation)
Voice options on MAYAH codecs include noise suppression, acoustic echo control, and automatic gain control. The CENTAURI IV 3001 can combine the above mentioned applications and do backup, gateway and recording/logging at the same time.
AJC - Automatic Jitter Compensation
Improves the IP connectivity with highly sophisticated automatic analysis and parameter setting mechanisms for bit rate, buffer and others.
FEC - Forward Error Correction
Line failures? Bit errors? No problem with the Pro MPEG FEC and its flexible settings for redundancy and performance.
PLEC - Packet Loss Error Concealment
Works without FEC optimizing the trade-off between buffer, bandwidth and redundancy. PLEC allows almost no buffer by maintaining high audio quality.
Dual IP, offers two mono encode/decode
You can split the device into two independent mono units, establishing two bidirectional mono connections via IP, instead of one bidirectional stereo connection.
Dual ISDN, offers two mono encode/decode
You can split the device into two independent mono units, establishing two bidirectional mono connections via ISDN, instead of one bi-directional stereo connection.
The CENTAURI IV 3001 supports up to 4 channels, twice that of our basic models.
Intercom Audio Mode
This unique intercom capability allows commentators to communicate with an additional person on-site by simply pushing a button.
Dual Reporter Mode
This mode allows users to send an audio transmission to up to 2 targets through one channel.
WebRemote 4.1 2015
Complete device monitoring and control is possible with our MAYAH Web Remote 4.1 2015.
Multichannel WebRemote 4.1 2015
Based on the very powerful but easy to use WR 4.1 2015, the new Multichannel WebRemote Control offers easy operation of up to 8 bidirectional channels.
The migration from ISDN to IP is ongoing. Instead of a complete switch which is supported by a variety of MAYAH products, the ISDN/IP Gateway solution offer a smooth transition.
After a line failure an automatic backup is used, which is supported by many MAYAH Audio Codecs. It is important that after everything is set back to normal, an automatic recovery to the original settings and lines is possible.
The monitoring, logging or automatic backup of the audio signal can be controlled in terms of duration and level.
You can split the device into two independent mono units, establishing two bidirectional mono connections via IP ISDN, instead of one bidirectional stereo via IP ISDN.

Redundant Audio Streaming
MAYAH supports redundant streaming for more stable and secure audio transmission. Two Ethernet ports are available to simultaneously output identical packets to the network or even to different networks. At the decoding side a control analysis determines the best stream and uses this for the decoding process.
Audio Signal Detection
MAYAH codecs possess highly sophisticated automatic analysis and parameter setting mechanisms. These make it easy to detect any problems with the signal or transmission.
SIP+ for enhanced usage of SIP
Simply register your MAYAH Codec at MAYAH FULL-SIP Server and be compatible with every other SIP Device and use features like ICE (Interactive Connectivity Establishment), FEC (Forward Error Correction) and Interconnect which enables connection without a STUN Server.
Easy unicast stream from one encoder to up to 11 remote locations. Good distribution alternative in networks without multicast support.
Point-to-Multipoint over ISDN
Distribute one signal over ISDN to up to 8 destinations using a single audio codec with 4BRI ISDN.
BGAN & KA Sat
All MAYAH audio codecs provide APN & Login Support for QoS on BGAN/Inmarsat connections. The most secure Audio-over-IP from every corner of the world.
Simultaneous Recording and Transmission
While fellow journalists just record their material to cut it and send it back to the studio later, you’re On Air with Audio-over-IP / 3G / Wi-Fi and still get your interview recorded as uncompressed audio on an SD Card.
Easy Backup for Audio-over-IP
Switch to the other IP or ISDN line automatically if signal is lost or play back the file from an SD card or USB.
