    Classic Stable Power You Can Trust
    Offering the classic Niles stability that you've come to know and trust, the powerful SI–2100 brings extremely high current power to a custom installed A/V System in a remarkably convenient way. Featuring audio circuitry constructed using the finest materials available, including 1% metal film resistors, high quality capacitors and oversized heat sinks that ensure proper cooling without the need for a noisy fan. This 2–channel amplifier provides 100W per channel (400W when bridged for higher output applications) and independent level control, making installation easier and more straight forward than ever before.

Details from Niles

    Real World PowerThe SI–250, the SI–2100 and the SI–2150 deliver 50 watts, 100 watts, and 150 watts per channel at 8 ohms and 100 watts, 220 watts, 270 watts per channel at 4 ohms respectively. Youa??ll get tremendous bass and dynamics from every pair of speakers connected.

    Transparent SoundThe audio circuitry of the Niles System Integration Amplifiers® is constructed using the finest parts available; including 1% metal film resistors, high quality capacitors, and oversized heat sinks. All this attention to technical detail creates a sound that is clear and uncolored with phenomenal imaging.

    Freedom From CrosstalkEach channel of the Niles System Integration Amplifier is powered via its own independent power supply. This increases the isolation between the two channels and eliminates cross talk, guaranteeing you absolute silence as the backdrop to your music.

    Current For Reactive Loads
    The high current design of the Niles System Integration Amplifiers assures that even unusual and reactive loads are handled with ease. A massive toroidal transformer (SI–250) and cutting edge digital power supplies (SI–2100, SI–2150) provide more than ample current to your system.

    Freedom From Fan Noise
    The oversized heat sinks inside the System Integration Amplifiers allow the amplifier circuitry to stay cool even when operating into low impedance loads without the distracting noise created when using fan–cooled amplifiers.

    Independent Level Controls
    Each amplifier channel features an independent level control enabling precise volume matching to the rest of the system. These level controls can also limit volume to prevent abuse of the system.

    Lifetime Connections
    The Niles System Integration Amplifier® family features gold plated stereo inputs, cascade stereo outputs, and five way binding posts to ensure perfect connections without corrosion for years to come.

    Turn–On Modes
    The Niles System Integration Amplifier® family features three turn–on modes:

    • 1. Music Sense
    • 2. External Voltage Trigger
    • 3. Manual Turn–On via the front panel switch
    You can configure a Niles Systems Integration Amplifier® to interface with any kind of system and have the unit automatically turn on.

    Automatic Protection
    The Niles System Integration Amplifier® family is equipped with sophisticated protection circuits. In the unlikely event that a problem occurs, the amplifier shuts itself off. When conditions return to normal, regular operation resumes.

    Status Display For Troubleshooting
    LED indicators on the front panel indicate: Power, Active Status, and a protection Warning. With a glance at the front panel, a troubleshooter is quickly provided with key information!

    Control Output
    A 12 Volt DC output is provided whenever the amplifier is on, allowing you to operate voltage triggered devices like motorized screens and curtains.

    Bridged Mode
    The Niles System Integration Amplifier® family can be operated in a bridged mono Configuration. In this configuration, the SI–250, the SI–2100 and the SI–2150 deliver 225 watts, 400 watts, and 550 watts respectively. Bridged mode is perfect for subwoofer, rock speakers or any applications requiring high power output.

    Compact 1u Design
    The SI–250, the SI–2100 and the SI–2150 all share the same compact low profile design requiring only a single rack space (1U). Designed and engineered IN the USA with limited two–year parts and labor warranty.
