  • Page 4: Introduction

    INTRODUCTION We call the SI-1650 a Systems Integration Amplifier because it is a power amplifier specifically designed to solve the problems of interfacing with different brands and models of equipment, different acoustic environments in different rooms, and different kinds of applications: home theater, stereo, and background music.

  • Page 5: Features And Benefits

    Signal to noise ratios and cross-talk are equivalent to a professional mixing board found in a recording studio. With the SI-1650, the music playing in the living room cannot interfere with the music in the den.
  • Page 6 TURN-ON MODES The SI-1650 features three turn-on modes: 1. Manual turn-on via the front panel switch, 2. Audio Sense and 3. External Voltage trigger. Audio Sense and External Voltage trigger modes enable you to configure the SI-1650 to interface with any kind of system and turn on automatically.

  • Page 7: System Design Basics

    To achieve different volumes and greater convenience in different rooms within a zone, individual volume controls can be used. Niles makes volume controls in various styles and colors. When designing your system, take into account who will use the system and when they will use it.
  • Page 8 SYSTEM DESIGN BASICS CONTINUED... A MultiZone system as shown in Figure 2, offers the household more flexibility. For instance, a family might have their family room wired for surround sound and their living room wired for background music. In a two zone system, the children can watch TV in surround sound while Mom and Dad are reading the paper and enjoying background music in the living room.

  • Page 9: System Design Considerations

    SYSTEM DESIGN CONSIDERATIONS CABLE AND WIRE Because the SI-1650 has many connections on the rear panel (see page 32 & 33), it is important that you correctly label all of the input cables and speaker wires. Label the cables and wires with their destination or source, rather than the SI-1650 terminal to which they are connected.
  • Page 10 AREAS THAT REQUIRE MORE VOLUME AND POWER All of the odd numbered amplifier channels of the SI-1650 (channels 1, 3, 5, 7, 9, 11, 13, and 15) include a power output of 50 or 100 watts that is selected using a web based IP Configuration utility.
  • Page 11 SI-1650 is critical when driving an 8 ohm load with amplifier channels configured to 100 watts. If the SI-1650 is not properly ventilated, the protection circuits may activate and shut off the channel at higher volume levels (for more information on proper amplifier placement, see Installation Considerations on page 29).

  • Page 12: Applications

    SI-1650 BusMatrix™ you dedicate a robust 50 watts to each speaker in your multi-room system. The SI-1650 has an IP Configuration and Setup tool to adjust volume and tone for each channel individually so you can compensate for architectural differences that create sonic imbalances.
  • Page 13 USING A DUAL-ZONE RECEIVER FOR TWO LISTENING ZONES Most of today’s Audio Video Receivers include a second zone preamplifier output to create a second listening zone. Using this output with the SI-1650 BusMatrix™ input provides amplification for multiple rooms within a second listening zone as shown in Figure 4.
  • Page 14 BusMatrix™ input signals are then routed to all the amplifier channels via the IP Configuration and Setup Tool. All eight rooms connect to the SI-1650 in Zone #6 with their own room volume control for adjusting room volume levels individually.
  • Page 15 In the ultimate MultiZone system, you connect individual stereo preamplifiers (or a single component multi-zone/multi-source preamplifier) to the BusMatrix™ inputs of SI-1650. These independent input signals are then routed to the appropriate amplifier channels via the IP Configuration and Setup Tool creating completely independent listening zones.

  • Page 16: Configuring Your System

    CONFIGURING YOUR SYSTEM Because the SI-1650 offers so many configuration possibilities it is important to plan carefully before you install it. Draw a block diagram of your system and use the Configuration Worksheet on page 41 to record how you plan to connect your SI-1650.
  • Page 17 DIRECT ETHERNET CONNECTION A direct Ethernet connection is made by connecting the RJ-45 network connector of a PC directly to the RJ-45 network connector on the rear panel of the SI-1650. Use the numbered steps below to establish network communication between a PC and the SI-1650 when using a direct wired Ethernet connection.

  • Page 28: Installation Considerations

    INSTALLATION CONSIDERATIONS TURN-ON MODES Automating the turn-on of your SI-1650 is one of the easiest steps when installing it in a distributed system. However, do not plug the main power cord into the switched AC outlet of your preamplifier or receiver. The high power design of the SI-1650 requires large amounts of current from its AC power source.
  • Page 29 The amplifier is off when there is no 3-24V AC or DC voltage detected at the trigger input. Voltage triggers can be supplied by Niles automated switchers, some video projectors, some surround sound processors, or something as simple as a 12 volt AC wall adapter plugged into the switched outlet of your stereo receiver.

  • Page 36: Operation

    Calibrate your system volume levels with the steps outlined below: 1. Lower all of the SI-1650 level controls to the minimum volume position. If there are any other amplifiers in the system, lower their level controls to the minimum (all of the amplifiers in your system must have level controls).

  • Page 37: Cleaning And Maintenance

    Even at levels like that, the SI-1650 will sound clear and clean. However, it requires more power to achieve a reasonable volume of sound in a large room than it does in a small room.
