FEATURES AND BENEFITS
Microcontroller Based Real World Power
The SI-1260 12 channel amplifier incorporates microcontroller technology which
maximizes the amplifier's operational efficiency and enables it to deliver a solid 60
watts per channel into 8 ohms, 20Hz to 20kHz, 0.04% THD. Its power increases to
80 watts per channel into 4 ohms, 20Hz to 20kHz, at 0.06% THD. The massive
Multi-Tap Toroid power transformer features 6 independent secondary windings, one
for 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 house
full of speakers.
Transparent Sound
The audio circuitry of the SI-1260 is constructed with the finest parts available
including the latest in discrete output transistor design, featuring 1% metal film
resistors, high quality capacitors and oversized heat sinks. All this attention to
technical detail results in a sound that is clear and uncolored.
Microcontroller Based Operation and Protection Modes
The SI-1260 utilizes advanced microcontroller based operation circuitry that moni-
tors all facets of the amplifier's operation and protection modes: over/under line
voltage, main power fuse status, channel pair on/off status, thermal protection, short
circuit/low impedance protection and DC output protection. Additionally, easy to
see front panel LED indicators display the operation or protection mode for each
channel pair (CH1/2, CH3/4, CH5/6, CH7/8, CH9/10 and CH11/12) as well as for
the amplifier's main power supply, providing fast and easy troubleshooting. In the
unlikely event that a problem occurs on one channel pair, the other channels will
continue to play. When conditions return to normal, regular operation will resume.
Dual Input BusMatrix ™ Selector
Nile’s unique Dual Input BusMatrix ™ selector gives you the flexibility to individually
assign each amplifier channel to a BusMatrix ™ input signal, either Left1, Right1,
Left1+Right1, Left2, Right2, Left2+Right2, or to a dedicated signal input. With the
BusMatrix
™ , routing surround sound to the master bedroom, stereo to the den, and
mono 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.
