Whether the application is for a standalone system controller or crossover, configured using front panel controls, or a comprehensive wireless networked system for Stadium or Arena sized tours, the Intelli-X² is designed to provide the solution that our clients demand. With a comprehensive preset library provided as standard, implementing the Intelli-series into your system couldn't be easier.

Designed to be Plug-and-Play, the Intelli-X² is simple to configure and integrate into any network. Whether the application is for a standalone system controller or crossover, configured using front panel controls, or a comprehensive wireless networked system for Stadium or Arena sized tours, the Intelli-X² is designed to provide the solution that our clients demand.

With a comprehensive preset library provided as standard, implementing the Intelli-series into your system couldn't be easier. Reliability hasn't taken a back seat either. Comprehensive test procedures including vibration and thermal tests, extended soak testing and the use of high reliability power supplies all ensure that the Intelli-X² is as reliable as possible against the rigors of life on the road.

The new Intelli-series consists of two system management devices, Intelli-X² 26 (2 in, 6 out) and Intelli-X² 48 (4in, 8 out), providing all the system management tools necessary for comprehensive system alignment and EQ, through to the provision of IIR and FIR based crossovers.

The new Intelli-series comprises a no-compromise design resulting in unmatched audio performance, even when using lower sample rates. The internal processing is selectable from 44.1 kHz to 192 kHz, providing full compatibility with both standard and high-end sample rate formats. Sample rate convertors are provided on the inputs as standard and may be switched in and out of circuit as required, enabling digital equipment operating at different rates to be connected.

A high degree of sonic quality in the analogue domain is also attained based on a no-compromise design philosophy. The new Intelli-series is equally at home in both live and studio applications. Intelli-X² I/O can be selected (in pairs) to be either analogue or AES3/EBU, enabling a mix of audio formats to be used simultaneously. Comprehensive front panel control means that reliance on computers to configure or tweak parameters is a thing of the past.

An exceptionally intuitive front panel, with integral LCD menu (using graphical icons similar to those used on many smartphones) makes operation of the Intelli-X² extremely quick to learn.

Critical attention has been focussed on synchronisation. Four sync options are available: Wordclock, AES A/B, AES C/D and internal. The Intelli-X² series manages synchronisation by providing a three-tiered redundancy approach, ensuring that if any sync source is lost, the Intelli-X² will automatically revert to another (as defined by the user) ensuring no loss in audio.

An integral date and time-based logging system is incorporated within all Intelli-devices. The log provides details of any key configuration/ control changes made and this log is available for viewing on the front panel display, or can be downloaded directly onto a computer.

The Intelli-series is designed to interface easily into any existing (or bespoke) Ethernet network via internal 3-way Ethernet switches. Both automatic IP (DHCP) and static IP configuration is provided as standard, enabling plug & play connectivity and more rigid IP assignments for use in fixed installations. SNMP support also provided. Wireless access points can be directly connected to Intelli-X² devices allowing direct control over a wireless network.
