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 Amplifier 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 Niles SI-250 Amplifier to interface with any kind of system and have the unit automatically turn on.
Bridged Mode The Niles SI-250 Amplifier can be operated in a bridged mono configuration. In this configuration, 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 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.
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.
Current for Reactive Loads The high current design of the Niles SI-250 Amplifier 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 Each channel of the Niles SI-250 Amplifier 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 amplifier is on, allowing you to operate voltage triggered devices like motorised screens and curtains.
