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 includ-
ing 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
monitors 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
