The documentation says Max 45 Meters Cat 5 cable. Is this Cat 5 cable ONLY (ie not Cat 5e or Cat 6) I have had issues in the past with video distribution on Cat5e and when replaced with cat 5 all worked fine. (Individual pair cable length issues) Does the digital audio suffer from this also ?? I assume the IR targets are extras and don't come with the amps. Are these the same as the ones used in the 8050 system ?? or different ordering codes. Does the Matrix switcher come with the IR leds ? or extras again Charles
