SYSTEMS INTEGRATION AMPLIFIER
SI
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 amplier 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 Amplier features
three turn-on modes: 1. Music Sense, 2. External
Voltage Trigger, 3. Manual Turn-On via the front panel
switch. You can congure the Niles SI-2150 Amplier
to interface with any kind of system and have the unit
automatically turn on.
■ Bridged Mode The Niles SI-2150 Amplier can be
operated in a bridged mono conguration. In this
conguration, 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 amplier 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 Ampliers allow the
amplier circuitry to stay cool even when operating
into low impedance loads without the distracting noise
created when using fan-cooled ampliers.
■ Current for Reactive Loads The high current design
of the Niles SI-2150 Amplier 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
Amplier 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 amplier is on, allowing you to operate
voltage triggered devices like motorized screens and
curtains.
