Niles Audio SI-2125 Amplifier Details

FEATURES AND BENEFITS

Real World Power
The SI-2125 delivers 125 watts per channel at 8 Ohms, 200 watts per channel at
4 Ohms and 300 watts bridged at 8 ohms. You’ll get tremendous bass and dynamics
from every pair of speakers powered by an SI-2125.

Transparent Sound
The audio circuitry of the SI-2125 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 Crosstalk
Each channel of the SI-2125 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 SI-2125 assures that even unusual and reactive loads
are handled with aplomb. A massive toroidal transformer with two separate windings
for each of the power supplies supplies more than ample current to your system.

Freedom from Fan Noise
The oversized heat sinks inside the SI-2125 allow the amplifier to stay cool even when operating into low impedance loads—without the noise of fan-cooled amplifiers.

Independent Level Controls
Each channel has its own independent level control enabling you to precisely
match the SI-2125 to the rest of your system. The level controls also enable you
to limit the volume, preventing abuse of the system.

Lifetime Connections
The SI-2125 features gold plated stereo inputs, the cascade stereo outputs as well as
the five way binding posts are gold plated to ensure perfect connections without
corrosion for years to come.

Turn-On Modes
The SI-2125 features three turn-on modes: 1. Music Sense 2. External Voltage Trigger 3. Manual Turn-On via the front panel switch. You can configure the
SI-2125 to interface with any kind of system and have the unit automatically turn on.

Automatic Protection
The SI-2125 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's 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 SI-2125’s can be operated in a bridged mono configuration. In this
configuration, it can deliver upwards of 300 watts. Bridged mode is perfect for
subwoofer, rock speakers or any applications requiring high power output.
