3FEATURES AND BENEFITSMicrocontroller Based Real World PowerThe SI-1260 12 channel amplifier incorporates microcontroller technology whichmaximizes the amplifier's operational efficiency and enables it to deliver a solid 60watts per channel into 8 ohms, 20Hz to 20kHz, 0.04% THD. Its power increases to80 watts per channel into 4 ohms, 20Hz to 20kHz, at 0.06% THD. The massiveMulti-Tap Toroid power transformer features 6 independent secondary windings, onefor each of the six amplifier modules. This extraordinary power supply design pro-vides the power necessary to deliver solid, deep, controlled bass response to a housefull of speakers.Transparent SoundThe audio circuitry of the SI-1260 is constructed with the finest parts availableincluding the latest in discrete output transistor design, featuring 1% metal filmresistors, high quality capacitors and oversized heat sinks. All this attention totechnical detail results in a sound that is clear and uncolored.Microcontroller Based Operation and Protection ModesThe SI-1260 utilizes advanced microcontroller based operation circuitry that moni-tors all facets of the amplifier's operation and protection modes: over/under linevoltage, main power fuse status, channel pair on/off status, thermal protection, shortcircuit/low impedance protection and DC output protection. Additionally, easy tosee front panel LED indicators display the operation or protection mode for eachchannel pair (CH1/2, CH3/4, CH5/6, CH7/8, CH9/10 and CH11/12) as well as forthe amplifier's main power supply, providing fast and easy troubleshooting. In theunlikely event that a problem occurs on one channel pair, the other channels willcontinue to play. When conditions return to normal, regular operation will resume.Dual Input BusMatrix™ SelectorNile’s unique Dual Input BusMatrix™ selector gives you the flexibility to individuallyassign each amplifier channel to a BusMatrix™ input signal, either Left1, Right1,Left1+Right1, Left2, Right2, Left2+Right2, or to a dedicated signal input. With theBusMatrix™, routing surround sound to the master bedroom, stereo to the den, andmono to a bathroom is as simple as flicking a switch. The Dual Input BusMatrix™makes the SI-1260 an ideal multi-room or multi-zone amplifier, offering the profes-sional installer exciting new features and sound system design possibilities.FEATURES AND BENEFITS
