I have a Tag Mclaren Aphrodite and 100X5R power amp. I want the Aphroditie to remotely switch on the power amp. IAG helpdesk say "power up the Aphrodite holding down 'TV', 'TAPE', and 'RANDOM' you will be offered the on/off choice for amp standby control. 'Search Forward' should switch it on the control, 'Search Back' should switch it off the control." I have put a Cat5 patch cable between Aphrodite-bus out to 100X5R- bus in but nothing happens. Does anyone know how this works?
