MODE SELECTION BUTTONS:
8. Digital Mode and Indicator
This button operates as a three-way toggle function. The LED immediately
above the button has two colors - RED and GREEN, and an OFF mode
where it is not illuminated.
When Digital Mode is selected, the decoder will automatically default to a
digital signal for the selected input if one is present.
If a digital signal is present and detected, the SP1.7 will automatically determine
the type of bitstream and select the proper decoding mode. The indicator
LED will turn green when this happens.
If NO DIGITAL SIGNAL is detected the SP1.7 will default back to the analog
input for the selected source. This also automatically puts the SP1.7 into its
Digital Standby Mode. When this occurs the LED indicator will turn RED
In this mode, the decoder will continually check the selected source inputs
for the presence of a digital signal. If one is detected, the SP1.7 will auto-
matically switch over to the pre-selected digital operation mode for that source.
To defeat this auto-digital detect mode you must press the button again. If
you do the LED will go OFF.
When this mode of operation is selected the SP1.7 will look at ONLY its
analog inputs. If a digital signal does appear the SP1.7 will NOT recognize
it and will remain in its analog only mode until you press the Digital button
again to either select the digital source or place the SP1.7 into its auto detect
mode as explained above.
9. Surround Button
Pressing this button will engage the SP1.7’s surround listening mode. When
this function is operational the LED will turn green. For Dolby Digital 5.1,
DTS 5.1, and DTS-ES 6.1 bitstreams, the signal will be decoded and pre-
sented with no additional post-processing. For 2-channel source material,
the SP1 will synthesize surround information based on the chosen Surround
Mode (see 31. for Surround Mode information).
