Utilizing our exclusive NexD\u2122 high-speed switching technologies, the ultra-compact RD400\/4 amplifier is designed to deliver loads of audio output power, with incredible efficiency and low distor<\/p>\n <\/span><\/p>\n Don’t let its modern styling and diminutive size fool you, this little powerhouse pumps out 100 watts of crystal-clear audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so It can be used as a 3-channel amplifier or a 2-channel amplifier producing a whopping 200W x 2 into 4 ohms.<\/span><\/p>\n For your convenience, the controls of the RD400\/4 are located on top of the amplifier, under a protective cover, with all connections located along one side of its chassis. Studio-grade signal processing features include 12 dB\/octave high-pass or low-pass filters (can be disabled) for each pair of channels, with continuously variable frequency selection from 50 to 500 Hz, and balanced inputs dual range differentials capable of accepting most voltage level inputs. Auto-activation capability (via signal detection or DC offset detection) is standard equipment, along with all-new input type switches for bridging stereo output channels without the need to use Y adapters.<\/span><\/p>\n Built-in LED clip indicators are also included with your RD400\/4. This brand new innovative feature allows you to easily adjust your amplifier’s input sensitivity settings quickly and accurately without special equipment. You’ll also find a handy set of preamp outputs, allowing you to feed signals to another amplifier almost effortlessly.
