Стереофонический усилитель мощности Behringer KM750

Behringer KM750 Power Amplifier

Lightweight, professional 750 watt 2-channel power amplifier (750 watts bridged; 2 x 400 watts @ 4 ohms; 2 x 200 watts @ 8 ohms) with ATR (Accelerated Transient Response) technology and ultra-high transient response. A workhorse for many years to come!

Proprietary Accelerated Transient Response technology uses huge pulses of energy (current and voltage) to quickly drive the woofer to match bass beats. With carefully selected transistors, high spin speeds and optimized other circuitry, this amplifier responds immediately to even the most demanding electronic bass impulses. This technology has revolutionized amplifier design with its outstanding performance and efficiency, delivering tighter, crisper and more natural sounding low frequencies.

Front panel controls and indicators are easy to use. When the power button is pressed, the Power LED will light up to indicate that the amplifier is ready for use. All channels have independent gain controls, and an LED indicator shows when the signal is distorted and the gain needs to be reduced. The signal LED also indicates the presence of a signal in the channel.

Balanced XLR and 1/4" TRS jacks are available on the rear panel, plus an unbalanced 1/4" TS jack, unbalanced RCA inputs, MONO on/off switch, stereo (two channel modes), mono bridge mode, switchable limiters for reliable overload protection. Speakers, on the other hand, can be connected to the amplifier both through screw terminals and through Twist-Lock connectors.
