Linea’s XiB4 is a four channel amplifier suitable for use anywhere a powerful, clean sounding product
with inbuilt DSP is required. Equally at home in portable PA, conferencing and contractor environments
the XiB4 is the perfect choice in any application where being tamperproof is important.
Remote operation is possible with Linea’s intuitive Podware PC application over BvNet, our installation
friendly network. BvNet is an RS485 based system that allows many XiB4 amplifiers to be ‘daisy chained’
over hundreds of metres using low cost cables and without the need for network switches etc.
Integration with other parts of a system is possible using dimple contact closure ports and Linea offer a
range of interface units that allow seamless connection to Ethernet and Dante.
The XiB4 also provides extensive fault and status logging including driver integrity monitoring. These
facilities are usually only associated with expensive specialised products and this is the first time that
they have been made available as standard features for no additional cost.
The advanced 96kHz DSP is fully integrated into the product and provides an array of unique and
genuinely useful features. Because all aspects of the DSP algorithms are designed and hand crafted in
house by Linea, they are not available on products from any other manufacturer. For example, LIR linear
phase crossover filters which are as easy to use as more conventional filter shapes, and have less latency
than FIR filters.
Each of the XiB’s four channels can deliver 1,250 Watts RMS in to 2 Ohms continuously, or up to 2,500
Watts in to 4 Ohms for a bridged pair of channels. Unusually these are not, ‘transient’, ‘burst’ or ‘peak’
power figures, they are the power levels that are delivered by all channels simultaneously even when
driven with the same dense program material.
With Linea amplifiers there is no need to ration power between channels, you can use all the power you
have paid for all the time.
Linea can do this because state of the art components and a finely optimised design results in an
amplifier that is more efficient than competitive products. This efficiency gain directly translates in to
the generation of less wasted energy (heat). In addition to reducing energy costs high efficiency results
in generous power reserves ensuring that pristine sound quality is maintained even under the most
extreme conditions.
