X Series


X Series Amplifiers

The X-series amplifiers are two-channel amplifiers at a compact size of 2U and 3U. All amplifiers in the X-series range offer clean and dynamic sound quality coupled with a reliability that you can depend on. The front control panel has two gain controls and the LED display informs about the condition of the amplifiers.

The rear panel of the amplifier has XLR input connectors and two XLR output connectors (link), two SPEAKON© outputs and four binding posts. The SPEAKON© connector of output 1 (left) is connected at all four poles. This connector offers the output signal of channel 2 (right) at the pins 2 (+/-). This enables a four-pole connection of two-way speaker systems with one speaker cable only. The bridged output is available via the binding posts. X-series amplifiers can be switched into three different operation modes: stereo, parallel and bridge mode. The amplifiers limiters can be switched on or off. All models are equipped with a switch-on delay to protect the connected speakers.

Safety circuits

The comprehensive package of safety circuits protects the connected speakers in case of component failure. All NOVA X-series amplifiers are equipped with the following safety circuits:

► Back EMF protection
Speakers are a complex and reactive load for an amplifier. Because of the high damping factor of all NOVA amplifiers the EMF effect figures not during normal operation. In case of a defective speaker the energy could be sent back to the amplifier. This energy could damage amplifier parts such as the transistors. All NOVA amplifiers are equipped with back EMF protection.

► Short circuit protection
A short circuit in a speaker or cable could damage the transistors of an amplifier. All NOVA amplifiers are equipped with short circuit protection.

► Overheating protection
All NOVA amplifiers are equipped with sensors at the transistors and transformers. Because of permanent monitoring of the temperature the built-in fans ensure sufficient cooling.

► HF protection
Extremely high frequencies could damage the voice coils of the connected loudspeakers. All NOVA amplifiers are equipped with HF protection circuits and filters.

► DC protection
DC (direct current) at amplifiers output could destroy the voice coils of connected loudspeakers. All NOVA amplifiers are equipped with DC protection circuits.
