    Thank you for purchasing the award winning Niles SI-1230, one of the most versatile and powerful multi-channel amplifiers ever offered. Like all Niles prod- ucts, the SI-1230 is built to the highest standards of quality and reliability. With proper installation and operation, you’ll enjoy years of trouble-free use.

  • Page 3: Introduction

    INTRODUCTION We call the SI-1230 a Systems Integration Amplifier because, for the first time, a power amplifier has been 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 back- ground music.

  • Page 4: Features And Benefits

    FEATURES AND BENEFITS Real World Power The SI-1230 is a 12-channel amplifier that delivers a solid 30 watts per channel RMS into 8 ohms and 37 watts per channel RMS into 4 ohms. The massive Multi- Tap Toroid power transformer features six independent secondary transformers for each of the six amplifier modules.
  • Page 5 Turn-On Modes The SI-1230 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 allow you to configure the SI-1230 to interface with any kind of system and turn on automatically.

    A zone can consist of just one room or a group of rooms. 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. Consult your local Niles dealer for more information.
  • Page 7 By connect- ing an SI-1230 to the preamplifier outputs of your stereo receiver (or preamp) you dedicate a robust 30 watts to each speaker in your multi-room system. Since each channel has its own level control, you can compensate for architectural differences that create sonic imbalances.
  • Page 8 If your system is remote controlled, or if you think that some of the users like to play the stereo too loudly, you can choose to calibrate the system so that it is limited to a volume level you assign. The SI-1230 allows you to set different volume levels for different rooms.
  • Page 9 For the first time, the SI-1230’s BusMatrix enables you to route mono to one speaker without affecting the quality of the stereo in the rest of the system.
  • Page 10 You connect the variable output of the CD player to the SI-1230 channels for a particular room where you are willing to listen only to CD’s. The fixed outputs remain connected to the main preamp or receiver so that you can listen to CD’s in the rest of the house.
  • Page 11 Adding Preamps to Create More Listening Zones In the ultimate multi-zone system you would connect six stereo preamplifiers (or a single component multi-zone or matrix preamp) to one SI-1230 and create six completely independent stereo systems. A system like this allows six people to simultaneously listen to different sources.
  • Page 12 You can easily add a second room of surround sound speakers by connecting five of the SI-1230 channels to the pre-outs of your surround system. If there is a pre- out/main-in loop, use a “Y” connector as shown so that the internal power ampli- fier can still be used in the main surround sound room.

  • Page 13: Configuring Your System

    Draw a block diagram of your system and use the Configuration Worksheet on page 29 to record how you plan to connect your SI-1230. Here is an example filled out according to the block diagram on page 11. Sample Configuration Worksheet BUS INS &...

    (see Figure 2). Place the SI-1230 so that there is at least 5” of free air space above the chassis. If the amplifier is located on a carpeted surface, place a board under the amplifier’s feet.
  • Page 15 Turn-On Modes The SI-1230 draws more current than a preamplifier’s switched AC outlet can safely supply. Also, your preamplifier may “thump” at dangerous volumes if the amplifier is already on when the preamp turns on. It is usually best to turn the amplifier on only when it is needed.

  • Page 18 Do not use speakers with an impedance of less than 8 ohms with a bridged channel. An unbridged channel of the SI-1230 is designed to play into a speaker load of four ohms or more. When a four ohm speaker is connected, the continuous power rating of the amplifier increases to 37 watts RMS per channel, (all channels driven).
  • Page 19 Cable and Wire Because the SI-1230 has so many connections on the back panel it is very impor- tant that you label all the input cables and speaker wires. If you label the cables and wires for their destination or source, rather than which terminal of the SI-1230 they are connected to, it will be easier to reconfigure your system in the future.

    5 amplifiers from each of its six outputs, allowing 30 SI-1230 power amplifiers to be fed from the same master preamplifier. If your preamp has a vacuum tube output stage, you must use a Niles AVDA-3 to drive more than a single SI-1230.
  • Page 25 This is much more than the typical acces- nience outlets. sory outlet on the back of a component will provide. Use the SI-1230’s auto turn- on circuitry to turn on the SI-1230 when- ever the preamp is on.

  • Page 26: Operation

    Even at levels like that, the SI-1230 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.

  • Page 27: Cleaning And Maintenance

    Cleaning and Maintenance The internal parts of the SI-1230 are electronic and require no maintenance. Once a year it is appropriate to twist the RCA connectors on each input to remove any oxidation and improve conductivity.

To test for a ground loop, try reversing the AC plugs of each of the components in the system, that have non polarized plugs.
