Frequently Asked Questions
- Q: What is the channel number of SI-1200?
A: There are a total of SI-1200 of 12 channels.
- Q: What is the continuous power output for each channel?
A: Per contract output is per channel – 25 watts at 8 ohms.
- Q: Are the channels able to be bridged for additional power?
A: Yes, bridge adjacent channels, up to six 50-watt channels can be made.
- Q: What speakers can be used with the SI-1200?
A: SI-1200 is intended to drive speeakers with an impedance of 4 ohms or greater open bridged channels and 8 ohms or greater when bridged.
- Q: What are turn-On Modes available?
A: The SI-1200 has a total of 3 turn-on modes, Music Sense, External voltage trigger and Manual Turn-on.
- Q: Describe how the BusMatrix functions?
A: Each channel can be assigned to a common Left, Right or Mono signal bus or to an individual signal input, this is done with the BusMatrix.
- Q: What will happen if the amplifier is hot?
A: When the amplifier or the hotter will trigger off the protection circuits, regular operation returns when the conditions become within the normal range.
