The input signal from the T APE IN jacks can be sent directly fr om the ST bus, and can also be monitored fr om the C-R OUT jacks or PHONES jack.
Master controls 15 —Owner’s Manual 3 T APE IN switch This selects the signal that w ill be monitored b y the C-R OUT jacks and PHONES jack: either the PFL/AFL bus, or the T APE IN jacks. 4 C-R MONITOR LEVEL (control room moni- tor level) control This adjusts the level of the signal that is sent to the C-R OUT jacks.
