Pre-amp mode
In pre-amp mode, Roon will be turned off and the MAN301R
will relay the audio from a digital input to all of its outputs. The
unit will automatically lock onto the clock that comes from
the selected input source. Supported clock rates are 44.1kHz,
48kHz, 88.2kHz, 96kHz, 176.4kHz, and 192kHz. Supported
word-lengths are 16 bits up to 24 bits.
In the audio settings, a digital volume control will appear. Its
setting will affect both the digital and the analogue outputs.
When the volume control is set to maximum (right-hand side),
the digital output will be bit-transparent.
If your unit does not have a DAC installed, the DAC settings (out-
put level, filter type, and polarity inversion) will be absent.
CD ripping mode
In CD ripping mode, Roon will be turned off and the MAN301R will enable you to rip CDs from the
internal CD drive onto an external USB storage device. To rip a CD, follow these steps:
1. Connect a USB storage device and tap the "check"
button in the USB drive section. If the device is rec-
ognized correctly, the status will change from "not de-
tected" to "mounted"
2. Insert a CD into the CD drive. If the disc is recognized
correctly, the status will change from "not detected" to
"detected" and the track list will be printed out in the
status window below. Please note: the CD drive may
need a while to access the discs. If the disc is not rec-
ognized immediately, wait for a couple of seconds and
tap "check" again
3. Start the ripping process by tapping the "start ripping"
button. If you wish to abort, tap the "abort ripping" but-
ton. This will stop the ripping, but it will not eject the
disc. To eject the disc, tap the "eject" button in the CD
media section
To rip a new CD, simply eject the current disc and insert a
new one: unmounting the USB storage is not necessary.
The files on the USB storage device may be then directly accessed via Roon or they may be copied
to another storage device for further use.
