- Key Specs
- Continuous Watts x Channel @ Ohms: 85 x 4
- Maximum Watts x Channel @ Ohms: 600W x 4 ohms (This is the maximum load the speaker, subwoofer or amp can drive.)
- Amplifier Class: AB (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: Yes (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).)
- 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
- Signal-to-Noise Ratio (SNR): 75 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: Yes (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.)
- Features
- Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
- MOSFET Power Supply: false (A specific type of power supply with the advantages of high switching speed and efficiency at low voltages.)
- Input
