  • Key Specs
    • Continuous Watts x Channel @ Ohms: 75W RMS x 4 @ 2 ohms, 50W RMS x 4 @ 4 ohms
    • Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
    • Number Of Channels: 4
    • Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
    • Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
    • Low-Pass Crossover: None (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • High-Pass Crossover: Selectable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

  • Audio
    • Number Of Channels: 4
    • Minimum Frequency Response: 26 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Maximum Frequency Response: 22 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Total Harmonic Distortion: 0.2 percent (Measurement of the harmonic sound distortion. The lower the percentage, the cleaner the sound.)
    • Signal-to-Noise Ratio (SNR): 106 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
    • Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
