Sensitivity is the minimum power an amplifier must supply to a speaker so the speaker can produce satisfactory volume ratings. Put simply, it measures how easily a device will conduct a current. Stated in ohms, impedance measures the resistance of a device to an Alternating Current (AC). The widely accepted frequency range of human hearing is 20Hz-20kHz. The frequency response is the range in Hertz (Hz) that a device can reproduce versus amplitude. A low-pass filter is typically adjustable allowing the user to choose which frequencies to continue to the subwoofer. A low-pass filter, which can be found on the Sub and Nuke subwoofers, eliminates or cuts off the high frequencies allowing only low frequencies to continue to the subwoofer. A crossover takes the signal and separates it into frequency bands, low frequencies, mid frequencies and high frequencies. What is the difference between a crossover and low-pass filter?Ī typical speaker can’t properly drive all the sounds in the audio spectrum. Additionally, the PP-2000 and PP-3000 are available in Bridge or Stereo mode. Currently every model in the L-Series and Slimpro Series is bridgeable.
#PROFESSIONAL POWER AMPLIFIER PRO#
Technical Pro offers multiple amplifiers which function in either Bridge or Stereo mode. Which Technical Pro Amplifiers can operate in either Bridge or Stereo mode? This will result in a voltage output twice that of an individual channel operating in Stereo mode. Bridge mode, also referred to as parallel mode, combines two output channels which are powered by a single input.
When an amplifier is operating in Stereo mode each channel is functioning independently, with a single input powering a single channel. What does it mean to operate an amplifier in Bridge Mode as opposed to Stereo Mode?įrequently amplifiers will operate in two modes, Bridge mode or Stereo mode. An amplifier is an electrical component that increases a signal, usually by increasing the voltage and the current.
