Niles Audio SI-1230 Details
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. As a result, the SI-1230 delivers twenty percent
more power than its predecessor, the SI-1200. This extraordinary power supply
design provides the energy necessary to deliver solid, deep, controlled bass
response to a house full of speakers.
Twelve to Six Channel Configurable Power
Each of the SI-1230's six adjacent 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 specific
locations, such as large rooms or outdoor applications.
Freedom from Noise and Cross-Talk
The SI-1230’s Input/BusMatrix™ PC board incorporates advanced 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.
Transparent Sound
The audio circuitry of the SI-1230 is constructed with the finest parts available,
including 1% metal film resistors, high quality capacitors and oversized heat sinks.
All this attention to technical detail results in a sound that is clear and uncolored.
BusMatrix™ Selector
Our unique BusMatrix selector gives you the flexibility 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 flicking a switch. BusMatrix makes the
SI-1230 an ideal multi-room or multi-zone amplifier and offers exciting new
features and system design possibilities to the professional installer.
Independent Level Controls
Each channel has its own independent level control enabling you to adjust the
volume settings for twelve different speaker locations. Each speaker can be
adjusted for its location and who uses it!
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.
Automatic Protection
Each channel has independent thermal and short circuit protection. In the unlikely
event that a problem occurs on one channel, the other channels will continue
to play. When conditions return to normal, regular operation resumes.
Status Display for Troubleshooting
LED's on the front panel indicate Power, Active and Protection Status. With a glance
at the front panel a troubleshooter is quickly provided with key information!
