Real World Power The SI–1230 is a 12–channel amplifier that delivers a solid 30 watts per channel RMS into 8 ohms and 40 watts per channel RMS into 4 ohms. A massive toroidal transformer design provides the energy necessary to efficiently deliver solid, deep, controlled bass response to a house full of speakers. Turn–On Modes The SI–1230 features three turn–on modes: 1. Manual turn–on via the front panel switch, 2. Audio Sense and 3. External Voltage trigger. Audio Sense and External Voltage trigger modes enable you to configure the SI–1230 to interface with any kind of system and turn on sutomstically. Twelve to Six Channel Configurable Power Each of the SI–1230's six adjacent speaker output pairs are bridgeable. You can create up to six 80 watt channels by sliding the bridging switches located between each pair to the "bridged" position. This enables you to allocate more power to specific locations, such as large rooms or outdoor applications. BusMatrix Selector Our unique BusMatrix selector gives you the flexibility to assign each channel to a common Left, Right, or Mono signal bus, or to a dedicated signal input. With BusMatrix, routing surround sound to the master bedroom, stereo to the den and mono to the powder room is as simple as flicking a switch. BusMatrix makes the SI–1230 an ideal multi–room or multi–zone amplifier and offers exciting new features and system design possibilities to the professional installer. Freedom from Noise and Cross–Talk The SI–1230's BusMatrix incorporates advanced PCB construction ensuring extremely high channel to channel isolation. Signal to noise ratios and cross–talk are equivalent to a professional mixing board found in a recording studio. With the SI–1230, the music playing in the living room cannot interfere with the music in the den.
