Front Panel Overview

1. Standby/on ( ) button
   Press this button to turn the unit on and put it in standby. The blue indicator lights when the unit is turned on.
   • When this unit is in standby mode, it still consumes some power, which is why the term "standby" or "standby mode" is used instead of "off".
2. Source button
   Each time this button is pressed, the source changes.
3. Input source indicators
   The indicator for the selected source lights. These indicators blink when the input signal is not a digital audio signal or is a digital audio signal in a format other than PCM or DSD (such as Dolby Digital, dts or AAC).
4. Sampling frequency indicators
   These show the sampling frequency of the input digital audio signal.
   When an input signal is locked, the indicator for its sampling frequency lights. These indicators blink when there is no input signal or the input signal is not locked.
   NOTE
   If the sampling frequency of the input signal is 32 kHz, no sampling frequency indicator will light, but the input indicator will light.
5. PHONES jack
   Connect headphones with a standard 6.3mm (1/4") stereo plug here.
6. VOLUME knob
   When the LEVEL switch is set to VARI, you can use this knob to control the audio level output from the analog audio output jacks (see "Connections").
   When headphones are connected, this knob also adjusts the headphones volume.

Be sure to set the VOLUME knob to MIN before putting on connected headphones. Do not turn the unit on or put it in standby or connect/disconnect headphones while wearing them. Doing so could cause a sudden loud sound, resulting in harm to hearing.
