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 opti- mum 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 acti- vation. 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 installa- tion time when using Niles Systems Integration Electronics. Niles multi-zone pre- amplifiers are equipped with a mating DB25 output connector. This output con- nector provides 6 zones of line-level audio signal output and a 12V Trigger Voltage for reliable amplifier activation.
Designed in the USA
The Niles SI-1260 was designed in the USA by Niles engineers and includes a two year parts and labor warranty.
