Niles Amplifier SI-1230

The Niles SI-1230 is a fully configurable 12-channel power amplifier designed primarily for multi-room or whole-house audio systems. It provides flexible power output and routing options for various audio setups.

Typical Applications

The SI-1230 is an ideal solution for professional installers wiring whole-house audio systems, allowing for a centralized amplifier to power speakers in up to twelve different locations or six stereo zones.

Key Features and Specifications

• Channels: 12 channels.

• Power Output:

o 30 watts RMS per channel into 8 ohms (all channels driven).

o 40 watts RMS per channel into 4 ohms (all channels driven).

o Bridgeable to 80 watts RMS into 8 ohms for adjacent channel pairs (creates six 80-watt channels for larger rooms or outdoor speakers).

• BusMatrix™ Selector: A unique feature allowing each channel to select its audio source from four options: Left Bus, Right Bus, Left Plus Right Bus (summed stereo), or the channel's dedicated input. This simplifies custom audio routing.

• Turn-on Modes: Three modes for flexible integration with different systems: Music Sense, Voltage Trigger (3-24VAC/DC), and Manual.

• Independent Level Controls: Each of the 12 channels has its own level control to balance volumes across different zones.

• High-Quality Construction: Built with high-quality components, including a massive toroidal transformer and oversized heat sinks for reliable, fan-less cooling and clear sound.

• Inputs/Outputs: Features RCA inputs (one per channel plus a stereo bus input), cascade outputs for daisy-chaining multiple amplifiers, and gold-plated 5-way binding post speaker connectors.

• Dimensions: Approximately 17.25" W x 5.75" H x 16.25" D.
