Niles SI-1260 Installation & Operation Manual

Most of today's Dolby Digital surround sound receivers include a second zone pre- amplifier output used to create a second listening zone. Using this output with one of the 51-1260's BusMatrix™inputs provides amplification for multiple rooms within a second listening zone as shown in Figure 6.

Using the individual level controls, the 51-1260 enables you to set a specific volume level for each of the different rooms connected. Individual room volume levels can be calibrated so that all rooms have similar volume control characteristics regardless of size and acoustics and to establish a maximum volume level. This is especially useful if your system is remote controlled, or if some of the users like to play the stereo too loudly. Calibrate your system's volume levels using the steps outlined below: 1. Adjust all of the 51-1260's level controls to the mi ...

In large or irregularly shaped rooms, you may find that the main listening area may be closer to one of the speakers. If the speakers in the room are connected to a stereo amplifier you will only hear half the music. The 51-1260's BusMatrix'" enables you to create mono sound from one speaker without impacting the stereo quality in the rest of the system. You can configure each room to either stereo or mono as needed with no ill effects. Some of the most popular areas where mono will greatly enhance the sound quality would be: • Large rooms with many seati ...

Each of the 51-1260'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 27 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 51-1260's Dual Input BusMatrix'M PC board ensures extremely high channel-to-channel isolation. 5ignal-to-noise ratio and cross-talk sp ...
