5. TOSLINK Digital Audio Optical Inputs

The SP1.7 offers two assignable TOSLINK optical inputs. These can be designated to any input using the OS menu (“Other Settings”)on the LCD screen. Please note that if you choose to assign an optical input to an input with a coaxial input, the coaxial will be over-ridden and the optical input signal will be used by the SP1.7. The pro model replaces the two TOSLINK connectors with a single AES/EBU Digital connector.

NOTE: On the pro model, ‘AES’ will show up in the ‘Other Settings’ Menu (instead of OPT1 and OPT2),

to setup the AES/EBU input assignment.

6. Tape/Recording Outputs

The SP1.7 provides two analog outputs for the TAPE and VCR sources. The front panel selected input signal is always routed to these tape outputs, except when TAPE or VCR is selected. In those cases the appropriate output is automatically muted to prevent feedback.
