Real World Power The SI-250 delivers 50 watts per
channel at 8 ohms and 100 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-250 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-250 Amplier
to interface with any kind of system and have the unit
automatically turn on.
Bridged Mode The Niles SI-250 Amplier can be
operated in a bridged mono conguration. In this
conguration, the SI-250 delivers 225 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-250 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-250 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.
Features & beneFits
Offering the classic Niles stability that you’ve come to know and trust, the powerful SI-250 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 50W per channel (225W when bridged
for higher output applications) and independent level control, making installation easier and more straight forward than
ever before.
