Name: SpeakerCraft - 480W 8.0-Ch. Amplifier Controller - Black
Brand: SpeakerCraft
SKU: 6081142
Rating: 0 (0 reviews)

Key Specs
- Continuous Watts x Channel @ Ohms: 60 Watt x 8 @ 4 Ohm
- Number of Channels: 8 (The number of discrete channels of sound output. This can be a single number or multiple numbers separated by decimal(s). The first number is the primary, horizontally directed audio channels. The number after the first decimal, if applicable, is the number of subwoofer outputs or channels. The number after the second decimal, if applicable, is the number of height or atmospheric channels designed to immerse the listener by producing overhead sound effects.)
- Preamp Outputs: true
General
- Product Name: 480W 8.0-Ch. Amplifier Controller
- Brand: SpeakerCraft
- Model Number: MRA-664
Audio
- Continuous Watts x Channel @ Ohms: 60 Watt x 8 @ 4 Ohm
- Maximum Watts x Channel @ Ohms: 30 Watt x 8 @ 8 Ohm (This is the maximum load the speaker, subwoofer or amp can drive.)
- Total Power Handling: 480 watts (How much amplifier (amplified) power (wattage) that can be handled before damaging the product.)
- Number of Channels: 8 (The number of discrete channels of sound output. This can be a single number or multiple numbers separated by decimal(s). The first number is the primary, horizontally directed audio channels. The number after the first decimal, if applicable, is the number of subwoofer outputs or channels. The number after the second decimal, if applicable, is the number of height or atmospheric channels designed to immerse the listener by producing overhead sound effects.)
- 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.)
- Signal-to-Noise Ratio (SNR): 100 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.)
Audio
- Impedance: 4 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
Inputs
- 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.)
- Line-Level Inputs: true (Also referred to as low-level inputs. Enables the amplifier to receive a sound signal from another device via RCA cables.)
Outputs
- Preamp Outputs: true
Features
- Bridgeable: false (Bridging an amplifier increases the power it supplies to the speaker(s).)
Dimensions
- Product Height: 3.5 inches (The out of box height of the item. Height is measured as the vertical distance from the bottom of the item to the top as it would be primarily used or placed.)
- Product Width: 17.2 inches (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
- Product Depth: 12.9 inches (The out of box depth of the item. Depth is measured as the distance from the front of the item to the back as it would be primarily used or placed.)
- Product Weight: 18 pounds (The out of box weight of the item.)
