Offering the classic Niles stability that you’ve come to know and trust, the powerful SI-1230 will exceed your installation
needs. Specically designed to solve the problems of interfacing with different brands and models of equipment, and
different rooms and applications, the SI-1230 makes installation easier and more straight forward than ever before. Fully
congurable, with 12-channels that provide 30W per channel (80W when bridged) and our unique BusMatrix™ Selector, the
SI-1230 is the perfect multi-zone or multi-room solution.
■Real World Power The SI-1230 is a 12-channel
amplier that delivers a solid 30 watts per channel
RMS into 8 ohms and 40 watts per channel RMS into 4
ohms. A massive toroidal transformer design provides
the energy necessary to efciently deliver solid, deep,
controlled bass response to a house full of speakers.
■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 you
to congure the SI-1230 to interface with any kind of
system and turn on sutomstically.
■Twelve to Six Channel Configurable Power Each
of the SI-1230’s six adjacent speaker output pairs are
bridgeable. You can create up to six 80 watt channels
by sliding the bridging switches located between each
pair to the “bridged” position. This enables you to
allocate more power to specic locations, such as large
rooms or outdoor applications.
■BusMatrix™Selector Our unique BusMatrix™
selector gives you the exibility to assign each channel
to a common Left, Right, or Mono signal bus, or to
a dedicated signal input. With BusMatrix™, routing
surround sound to the master bedroom, stereo to
the den and mono to the powder room is as simple
as icking a switch. BusMatrix™ makes the SI-1230
an ideal multi-room or multi-zone amplier and offers
exciting new features and system design possibilities to
the professional installer.
■Freedom from Noise and Cross-Talk The SI-1230’s
BusMatrix™ incorporates advanced PCB construction
ensuring extremely high channel to channel isolation.
Signal to noise ratios and cross-talk are equivalent to a
professional mixing board found in a recording studio.
With the SI-1230, the music playing in the living room
cannot interfere with the music in the den.
