    A. No, Class -I amplifi ers are a fundamentally different design from all other amplifi er classes on the market. Crown has patented the technology behind Class-I amplifi ers and is the only manufacturer in the world building this design.
  • Page 29 A. No. The DSP is an integral part of the I-Tech, not just bolt-on signal processing. By integrating the DSP into I-Tech, Crown engineers have been able to dramatically improve signal-to-noise, and use this integration to allow intelligent control of amplifi er operation.
  • Page 30 Q. If I use I-Tech and Macro-Tech A. There is a ~1 ms difference between I-Tech and Macro-Tech amplifi ers, as well as any other Crown amplifi er using the Grounded Bridge Q. What is latency, and does I-Tech have a fi xed latency? A.
  • Page 31 Q. What happens if the amp loses digital signal? A. The analog connections can be confi gured as backup and the amplifi er will switch to those connections auto- matically.
