  • Key Specs
    • Continuous Watts x Channel @ Ohms: 100W x 2 x 4 ohms
    • Input(s): None
  • General
    • Product Name: 2-Channel Bridgeable Power Amplifier
    • Brand: Niles
    • Model Number: SI-250
    • Color: Black
    • Color Category: Black
  • Audio
    • Continuous Watts x Channel @ Ohms: 100W x 2 x 4 ohms
    • Maximum Watts x Channel @ Ohms: 8-ohm configuration: 50W; 4-ohm configuration: 100W (This is the maximum load the speaker, subwoofer or amp can drive.)
    • Number of Channels: 2 (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.)
    • Impedance: 2.66 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.)
    • Minimum Frequency Response: 5 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: 25 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.)
    • 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.)
    • Signal-to-Noise Ratio (SNR): 102 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.)
    • MOSFET Power Supply: false (A specific type of power supply with the advantages of high switching speed and efficiency at low voltages.)
    • 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.)
  • Feature
    • App Compatible: false (The product can be connected to a program or software application on a mobile device, which then receives collected data from the product.)
    • Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
    • Fan Cooled: false
  • Connectivity
    • Wi-Fi Built-in: false (Able to connect directly to a wireless network without the use of an adapter.)
    • 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.)
  • Input
    • Input(s): None
  • Output
    • Preamp Outputs: true
  • Dimension
    • Product Height: 2.25 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: 17.25 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: 13.5 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.)

Enjoy high-quality audio with the help of this Niles SI-250 power amplifier, which features 2 bridgeable channels with independent level controls for simple sound customization. The independent power supply helps ensure crystal-clear output by eliminating crosstalk.

    • 200W RMS power (100W x 2 channels @ 4 ohms): Along with 100W RMS power (50W x 2 channels @ 8 ohms) for powerful audio output. Bridge mode delivers 225W of power in a bridged mono configuration.
    • High-current design: Allows the amplifier to handle unusual and reactive loads with ease.
    • Independent level controls: Enable precise volume adjustment.
    • Metal film resistors, high-quality capacitors and oversize heat sinks: Ensure crystal-clear audio.
    • 3 turn-on modes: Include music sense, voltage trigger and manual for simple operation.
    • Independent power supply: Increases isolation between channels and helps eliminate crosstalk for interference-free sound.
    • Rack-mountable design: Offers flexible placement options.
