In addition to the standard input RCA signals, the amplifiers have a high-level signal input for connection to the factory audio system. The auto-on function working with the high-level input has been enhanced with a new EPS circuit. It prevents unwanted malfunctions when using the high-level input when connecting to the original factory headphones.
The best sound quality is provided by fast operational amplifiers with a rise rate of 9V/ms. Thanks to this, even the smallest sound details are processed carefully.
Monoblocks from the GTS series - as one of the few on the market - also have high-level inputs. They are characterized by an efficiency of up to 86%. They also have the ability to simultaneously connect two identical amplifiers into one power summing up at 2 Ohm - master/slave system.
All models have a number of filters that allow you to perfectly set the sound parameters depending on the needs and speakers used.
