XPS 1400 is a 2-channel power finish in an extremely compact and lightweight DH class. Equipped with high efficiency SMPS (switching power supply), combines lightness and performance in only 2 rack units. The front panel has two gain controls and the main dirtutor. Two LED displays inform the condition of the amplifiers. The back shows 2 XLR inputs and 2 XLR outputs (link). Linput sensitivity (gain) is 32 dB. The Speakon channel connector 1 It is connected with all four poles and offers the output signal of the channel 2 (right) to the feet 2 (+ /-). This allows an efficient 4-pole connection of two-way systems with a single power cable. The XPS final series can operate in 3 modes: stereo-parallel-bridge. The integrated crossover is equipped with a filter passes-High and a filter passes-Low (every 18 db / butterworth). The filter type can be set and activated by a switch on the rear panel. The crossover function is off in Fullrange position. Switchable impedance adaptation function that can be set with OVP interrupt switch to the rear panel, ensuring output power even at low impedances. Equipped with a function delay to protect the connected speakers.

Features

• The DH class finals are the evolution of class technology-H. Sound free of distortions thanks to the continuous control of the supply voltage, greater efficiency and lower energy consumption, less heat and extremely reduced power loss
• Design The OVP is a special dynamic power supply converter that is able to provide more energy even at low impedances. To pilot a higher impedance (such as a speaker with an 8 ohm impedance) a higher voltage is required. Using the OVP switch (not available in the XPS 900), the user can adjust the amplifiers NOVA XPS exactly to the impedance of the connected speaker.
• High efficiency integrated crossover advantages X-Over: For larger and larger speaker systems, it is recommended to use a digital speaker management system, which takes on a crossover. For smaller systems, such as a system consisting of two DA18 "subwoofers and two-way mid / high speakers, it is possible to contain costs use amplifiers NOVA XPS that are equipped with a high pass filter (120Hz / 18DB / Butterworth) and a pass-Low filter (120Hz / 18db / butterworth). You can select the filter type on the back side of the XPS amplifiers using a switch. The function crossover is disabled in Fullrange position. Advantage of this system X-Over: high flexibility and great performance even in smaller systems
• The SMPS system guarantees low without distortion. The core of the amplifiers NOVA XPS is the SMPS a dynamic variable voltage regulator that offers stable performance even with voltage fluctuations in the network power supply (230V ~ + /-10%). The power supply is designed specifically for class DH amplification technology-NOVA, it provides a stable power supply for performances without compromises even at full load and low impedance.
