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 provides 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 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™ makes the SI-1260 an ideal multi-room or multi-zone amplifier, offering the professional installer exciting new features and sound system design possibilities.
Twelve to Six Channel Configurable Power
Each of the SI-1260's six adjacent output pairs are bridgeable. You can create up to
six 120-watt channels by setting the bridging switch to the "BRIDGED" position.
These switches are located at the top of the rear panel (see Page 21 Figure 16).
Bridging enables you to double the power to specific speaker locations, including
large rooms and outdoor applications.
Freedom From Noise and Cross-Talk
The unique design of the SI-1260's Dual Input BusMatrix™ PC board ensures
extremely high channel-to-channel isolation. Signal-to-noise ratio and cross-talk
specifications are comparable to those of mixing consoles used in professional
recording studios. With the SI-1260, the music playing in the living room will not
interfere with the music playing in the den.
Independent Level Controls
Each channel has its own independent volume level control, enabling you to
individually adjust the setting for up to twelve different speaker locations for optimum
audio performance, providing uniform sound in every room.
Turn-On Modes
The SI-1260 features three selectable turn-on modes: (1) manual turn-on via the front panel switch, (2) microcontroller enhanced audio sensing which activates only the appropriate amplifier channels while leaving unused channel pairs off to eliminate
cross talk and (3) a 3-30 volt AC/DC voltage trigger input which enables voltage activation. Audio Sense and External Voltage trigger modes enable you to configure the SI-1260 to turn on automatically in any kind of system configuration.
DB25 Audio & Voltage Trigger inputs
The SI-1260 incorporates a DB25 input connector to reduce wiring and installation
time when using Niles Systems Integration Electronics. Niles multi-zone preamplifiers
are equipped with a mating DB25 output connector. This output connector
provides 6 zones of line-level audio signal output and a 12V Trigger
Voltage for reliable amplifier activation.
