Applications
CI-1RR in a HI-FI system
Connect the CI-1RR in between your preamp and power amp to eliminate noise without affecting the signal quality. The CI-1RR’s exceptional frequency response, phase accuracy and signal handling makes it perfect for high-end 2 channel systems.
CI-1RR in a home theater
Combining video and audio together in home theater setups can often lead to noise. The Iso-Max CI-1RR solves the problem by isolating the video playback system from the multi-channel audio system, eliminating the hum and buzz caused by ground loops and DC offsets.
CI-1RR in a your car
Car audio enthusiasts know the challenges of ground hum polluting their audio. Turning up the volume only amplifies the problem. Isolating the radio/receiver from the power amp eliminates buzz caused by ground loops. The CI-1RR does it perfectly without affecting the performance.
