CAUTION
When using this unit (as a preamp) connected to a power
amplifier, always set the LEVEL switch to VARI and mini-
mize the volume knob before turning the amplifier on. If

The indicators light for the selected source and input sampling frequency.
o The input source indicators blink when the input signal is a digital audio signal in a format other than PCM
or DSD (such as Dolby Digital, dts or AAC). If this is the case, check to see if the connected digital audio
output device has a "PCM" setting for the digital output format. Refer to the operation manual for that
device to make this setting.
o The sampling frequency indicators blink when there is no input signal or the input signal is not locked.
o If the sampling frequency of the input signal is 32 kHz, no sampling frequency indicator will light, but the
input indicator will light.
o When using a Windows computer connected to this unit by a USB cable, you must install the dedicated
driver on that computer in order to play audio files through this unit (see page 12).
