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. The Niles SI-1650 Systems Integration Amplifier brings extremely high current power to a custom installed A/V System in a remarkably convenient way. - SI1650

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS FEATURES AND BENEFITS REAL WORLD POWER The SI-1650 is 16-channel amplifier configurable to deliver a solid 50 watts per channel RMS into 8 ohms or 100 watts per channel RMS into 8 ohms using a special high power mode. A new digital power transformer design provides the energy necessary to efficiently deliver solid, deep, controlled bass response to a house full of speakers.

FEATURES AND BENEFITS CONTINUED... IP CONFIGURABLE EQ ADJUSTMENT, VOLUME LEVEL AND HIGH/LOW PASS SELECTION A web based IP Configuration utility provides independent EQ adjustment and volume level for each amplifier channel enabling you to EQ and set volume levels for 16 different speakers individually. A High/Low Pass Filter setting for each channel accommodates passive subwoofers and small full range speakers. Installers can now acoustically optimize each speaker for both its type and in

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS SYSTEM DESIGN BASICS As shown in Figure 1, a distributed audio/video system is defined by the number of listening zones it has. Within a listening zone you can listen to only one source (e.g. CD, Radio, iPod, etc.) at any one time. A listening zone can consist of a single 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 c

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.

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS 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. This will make it easier to reconfigure your system in the future. The SI-1650 connects to your sources via shielded

SYSTEM DESIGN CONSIDERATIONS CONTINUED... CREATING HIGH POWER AMPLIFIER CHANNELS FOR 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. When an odd numbered amplifier channel is configured to100 watts, it’s even numbered adjacent amplifier channel (e.g. channel 1 and 2, channels 3 and 4, channels 5 an

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS SYSTEM DESIGN CONSIDERATIONS CONTINUED... SPEAKER COMPATIBILITY Any SI-1650 amplifier channel configured to the 50 watt mode is capable of driving a 4 ohm impedance speaker load. No more than two 8 ohm speakers or no more than one 4-6 ohm speaker can be safely connected to a single channel. Proper ventilation of the SI-1650 is critical when driving lower impedance loads. If the SI-1650 is not properly ventilated, the protection circuits may ac

APPLICATIONS ADVANTAGES OF USING THE SI-1650 IN A SINGLE ZONE SYSTEM When you connect the preamplifier outputs of your stereo receiver or stereo preamplifier to the 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. In addition, you can fine tune the system so t

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS APPLICATIONS 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. In addition, in this example high power is supplied to the patio stereo speakers by configuring channel 13 for high power

Zone 1 Zone 2 Zone 3 Zone 4 Zone 5 APPLICATIONS EXPANDING A MULTIZONE SYSTEM TO INCLUDE MORE ROOMS Many MultiZone systems incorporate multiple rooms within a single zone. The SI-1650 BusMatrix™ Input simplifies the connections required for this system design. As shown in Figure 5, a Niles ZR-6 MultiZone Controller has its speaker outputs connected directly to speakers in zones 1-5. The ZR-6’s preamp output six, set to a fixed output mode, is connected to the SI-1650’s BusMatrix™ inputs. Th

16 CHANNEL, FULLY CONFIGURABLE POWER AMPLIFIERS APPLICATIONS ADDING PREAMPS TO CREATE MORE LISTENING ZONES 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. MultiZone systems enable listeners lo
