4 Channels


High performance 96kHz DSP

9,5kg (20 lbs)

The XiT4 is a four channel amplifiers optimised for lower demanding pro audio applications. Offering a unique combination of power output, audio performance and combined with advanced 96kHz DSP and network control.

Sharing the same form factor as Tecnare’s T44&48 Series amplifiers, each of the XiT4 four channels can deliver 1250 Watts RMS in to 2 ohms continuously, or up to 2500 Watts in to 4 ohms for a bridged pair of channels. These are not burst or peak power figures, they are the power levels that are delivered by all channels simultaneously.

With the X Series amplifier there is no need to ratio power between channels, you can use all the power in any format as you please, even when the driven with the same dense program material.

Remote control operation is via the PC application ‘System Engineer’. The system engineer application provides convenience and time saving features such as very flexible management of presets, Overlay grouping of Mutes, Gains, Delays and EQ across an entire system. BvNet is a RS485 based system that allows many XiT4 amplifiers to be ‘daisy chained’ over hundreds of metres, using low cost Rj45 cables without the need for a network switch. You can also connect via USB.

The XiT4 also provides extensive fault and status logging including driver integrity monitoring. These facilities are usually only associated with very expensive specialised products and this is the first time that they have been made available as standard features for no additional cost.
