Front Panel
The front panel is quite simple with no user controls. LEDs indicate power, the
input source, the sampling frequency and whether an option is installed and is
active.
Power - The blue power LED lights up any time power is applied. The LINK should
always be left plugged in with the blue LED lit.
Option - The option LED will never light unless an option is installed. It indicates
a specific function for each option, such as upsampling or HDCD. It will light in the
full brightness and half brightness mode for further differentiation between mul-
tiple options. The Gold LINK comes with upsampling installed, so the option LED
will light whenever the upsampling toggle switch on the back panel is turned on.
Source - Both the coaxial and optical inputs are indicated on the display with
separate LEDs. When an active digital signal is attached to the LINK III the LED
will light, even if no music is playing, or the source is data (like Dolby Digital or
DTS). If both sources are active, both LEDs will light, but the COAXIAL input will
take priority. If a balanced or 192k input is sensed, that input takes priority over
both single-ended inputs but no indication is made on the input LEDs. They
continue to indicate that status of the single-ended inputs.
Sample Frequency - These LEDs indicate the incoming sampling frequency, whether
music is playing or not, and whether the source is data or not. When upsampling is
selected, the LEDs indicate the frequency of the upsampled data, not the source.
As no LED was provided for 132k, no LEDs light when upsampling to 132k, but the
option LED reminds you that upsampling is on. The 192 LED will not light without
a 192 source present on the balanced input, and the proper setup configuration
made inside the unit.
