Offering the classic Niles stability that you’ve come to know and trust, the powerful SI-2150 brings extremely high current
power to a custom installed A/V System in a remarkably convenient way. Featuring audio circuitry constructed using the
nest materials available, including 1% metal lm resistors, high quality capacitors and oversized heat sinks that ensure
proper cooling without the need for a noisy fan. This 2-channel amplier provides 150W per channel (550W when bridged
for higher output applications) and independent level control, making installation easier and more straight forward than
ever before.
■ Real World Power The SI-2150 delivers 150 watts
per channel at 8 ohms and 270 watts per channel at 4
ohms. You’ll get tremendous bass and dynamics from
every pair of speakers connected.
■ Turn-On Modes The Niles SI-2150 Amplier features
three turn-on modes: 1. Music Sense, 2. External
Voltage Trigger, 3. Manual Turn-On via the front panel
switch. You can congure the Niles SI-2150 Amplier
to interface with any kind of system and have the unit
automatically turn on.
■ Bridged Mode The Niles SI-2150 Amplier can be
operated in a bridged mono conguration. In this
conguration, the SI-2150 delivers 550 watts. Bridged
mode is perfect for subwoofer, rock speakers or any
applications requiring high power output.
■ Independent Level Controls Each amplier 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.
■ Freedom from Fan Noise The oversized heat sinks
inside the System Integration Ampliers allow the
amplier circuitry to stay cool even when operating
into low impedance loads without the distracting noise
created when using fan-cooled ampliers.
■ Current for Reactive Loads The high current design
of the Niles SI-2150 Amplier assures that even unusual
and reactive loads are handled with ease. Cutting edge
digital power supplies provide more than ample current
to your system.
■ Freedom from Cross-Talk The Niles SI-2150
Amplier is powered via its own independent power
supply. This increases the isolation between channels
and eliminates cross talk, guaranteeing you absolute
silence as the backdrop to your music.
■ Control Output A 12 Volt DC output is provided
whenever the amplier is on, allowing you to operate
voltage triggered devices like motorized screens and
curtains.

    What to do if my Niles SI-2159 Amplifier has no sound on one channel?
    • B
      burnettericAug 11, 2025
      If there's no sound on one channel of your Niles Amplifier, it could be due to several reasons: * A short circuit or loose wire at the speaker or amplifier terminals. Ensure connections are secure and no wire strands cross from positive to negative terminals. * A short circuit or break in the speaker wire. Disconnect the speaker wire at both ends, separate the conductors, and test for a short circuit with a meter. * The speaker is not working. Connect the speaker to a channel that is known to be working. * A bad audio cable to the input. Try connecting another cable that you know is good.

    Why is there hum from the speakers connected to my Niles Amplifier?
    • M
      Mr. Lawrence Burton PhDAug 31, 2025
      Humming from the speakers connected to your Niles Amplifier can arise from several factors, including faulty cables, faulty source material, an ungrounded phono system, or a defective component. Inspect these elements to identify the root cause.
