Engineering MAN301R Music Server
Foreword
Congratulations on purchasing the MAN301R Music Archive Network Player!
We hope that your unit will provide you with countless hours of music
listening.
Please make sure to read this user manual before getting started.
A short history of the MAN301R
Several years ago we introduced the MAN301 music archive network player. It
was built around the philosophy of CD ripping, audio file downloads, internet
radio streaming and metadata editing. The MAN301 was and is a very valuable
device for these purposes.
In the meantime, however, streaming of high quality music sources has mostly
taken the place of playing local files. This motivated us to “reconfigure” the
MAN301 for streaming purposes by integrating the Roon platform into it.
Roon is one of the best platforms for the music lover, because it gathers
streaming functionality along with the management of your local music library.
We have kept alive the CD ripping feature as well as the the pre-amp mode,
which converts the MAN301R into a transparent D/A converter.
With all these features in mind, the new MAN301R model is once again at the
state of the art for music playback.
First steps
Set up the MAN301R hardware
Carefully unpack the MAN301R unit. The following items should be included:
- The MAN301R unit
- This user manual with a warranty card
- The WiFi antenna
After unpacking the MAN301R, screw on the antenna onto the appropriate socket
on the back of the unit. It can be rotated to the position you like best.
The antenna does not have to be mounted if you do not need the WiFi access
point functionality of the MAN301R.
Connections
The MAN301R has the following wired connectivity:
- RJ45 gigabit Ethernet
- USB 2.0
- Digital audio: XLR input/output, S/PDIF input/output, optical input
- Analogue audio (if DAC board is present): RCA output, XLR output
Ethernet
Please make sure to connect the Ethernet port to your router. The MAN301R is
operated through a web interface, which requires you to be connected on the
same network.
USB 2.0
The USB 2.0 connector can be used for attaching music storage devices like
hard disks (HDDs) or solid state disks (SSDs). Supported file systems are
FAT32, exFAT, NTFS, and ext2/3/4.
Digital audio
The MAN301R supports up to two channels of 192kHz/24bit digital audio. No more
than one of the digital inputs (XLR, S/PDIF, optical) can be active at the
same time. The digital outputs (XLR and S/PDIF) are active at the same time
and deliver the same audio content.
Analogue audio
For units with a DAC, two channels of analogue audio are available. The RCA
and XLR outputs are active at the same time and deliver the same audio content
as the digital outputs. The RCA or XLR connectors can be used to drive
headphones through an adapter cable (sold separately).
Mains power on/ off switching
The MAN301R will automatically accommodate for the mains voltage, so there is
no mains voltage selector to set. The fuse rating is the same for all mains
voltages.
To turn on the MAN301R, press the “on” switch on the front panel. The blue LED
will light up. After about a minute or so, the MAN301R has booted and is ready
to be accessed through its web interface.
The MAN301R can be switched off from within the web interface or via the power
switch on the front panel. If switched off from the front panel, the LED turns
green and starts to flash until the MAN301R has shut down. If the green LED
does not stop flashing for more than 5 minutes, you may force a power down by
pressing and holding the power switch until the LED goes off.
Booting, WiFi
After having connected all necessary devices to the MAN301R (including the
power cord), switch on the MAN301R and wait about a minute until it has
booted.
In order to access the web interface, make sure that your
phone/tablet/computer is connected either your own local WiFi or the WiFi of
the MAN301R:
- The WiFi network is called man301r-XXXX, where XXXX is the serial number printed on the back of your unit
- The default password is WeissMAN301R
Please note: the MAN301R requires to be connected to an Ethernet router. Without a router, you will not be able to connect to the MAN301R WiFi network.
User interface
TheMAN301R is operated through a web interface, which is optimized for phones,
tablets and desktop computers.
Accessing the web interface
Pre-requisites
In order to operate the web interface, you need a device or a browser which
complies with at least one of the following requirements:
Browser/Device | Minimum version |
---|---|
Chrome | 60 |
Firefox | 60 |
Firefox ESR | No minimum version |
iOS | 12 |
Safari | 12 |
Connecting to the web interface
First, find out the serial number of your MAN301R.
It is written on the back of your unit. In your browser, simply type the
following link: man301r-XXXX.local
where XXXX is the four-digit serial number. For the unit depicted above, the
link would be: man301r-1130.local
Switching between modes
In the top section of the web interface, you can select one of three modes: roon server mode, preamp mode, and CD ripping mode.
Roon server mode
When “roon server” mode is selected, the MAN301R hosts a Roon instance that
can be accessed by all devices in the same network with the Roon app
installed.
Roon is a software for managing local music libraries, lossless streaming from
certain platforms (e.g. Tidal, Qobuz, KKBox), and web radio.
The Roon app is available for phones, tablets and desktop computers. It
requires a monthly subscription or a one-time purchase. For more information,
please visit the Roon website: https://roon.app
If yourMAN301RhasaDAC installed, you will have three audio settings at your disposal in the web interface:
- DAC output level selection, in 10dB steps
- DAC filter type
- DAC polarity
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 addition to the three physical inputs (XLR, RCA and optical) you can enable
UPnP or AirPlay streaming to the device.
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. The volume control is not available with UPnP
and AirPlay inputs.
If your unit does not have a DAC installed, the DAC settings (output 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:
- Connect a USB storage device and tap the “check” button in the USB drive section. If the device is recognized correctly, the status will change from “not detected” to “mounted”
- 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 recognized immediately, wait for a couple of seconds and tap”check” again
- Start the ripping process by tapping the”start ripping” button. If you wish to abort, tap the “abort ripping” button.
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.
There are two options available for CD ripping: output format selection
(“wave” or “flac”) and metadata lookup (“off” or”on”).
Output format The available formats are “wave” and “flac”. When “wave” is
selected, the tracks will be left unaltered after ripping. When “flac” is
selected, all tracks will be compressed to FLAC, a lossless audio format that
usually achieves 40%-50% compression when compared to WAV. The result of the
decompression is bit-perfect.
Metadata lookup When metadata lookup is set to “off”, each ripped CD will be
placed in its own folder with the following naming scheme: CD-RIP-YYYY.MM.DD-
HH.MM
where YYYY, MM and DD are the current year, month and day, while HH and MM are
current hour and minute. Each track inside the folder will be named with the
following naming scheme:
track01.cdda.wav
track02.cdda.wav
track03.cdda.wav
…
When metadata lookup is set to “on”, the MAN301R will attempt to correctly
name the folder and the tracks based on the artist, release and track names.
Roon metadata lookup If the integrated metadata lookup fails, or if you prefer
to use Roon for this purpose, follow these steps:
- Install the Roon desktop app (available for macOS and Windows)
- Make sure that the USB drive is added to your Roon library
- Use the export function to save the ripped CD to your favorite location. This function will cause Roon to look up the release in the Roon database. If a match is found, the exported release will be renamed and metadata will be inserted in each track
System section
At the bottom of the user interface, there is a system section which allows you to do the following:
- turn off/on the WiFi access point
- change the password of the WiFi access point
- update the MAN301R firmware
- shut down/reboot your unit
Managing the WiFi access point
The WiFi access point is turned on by default. This is done to guarantee that
you can reach the web interface if you are not in range of the WiFi network of
your router, or if your router does not have WiFi capabilities. Please note:
it is highly recommended to change the default access point password by the
tapping the”change password” button.
If you want to turn off the access point, simply select the “off” toggle. The
user interface will ask you for confirmation, since this action requires a
system reboot.
The access point can be turned on again with the “on” toggle. Once again, a
reboot will be required.
Updating the firmware
If you simply wish to check whether a new firmware version is available,
select the “check for updates” toggle. A window will appear, showing the
installed firmware version, latest firmware version, and hardware revision
number.
If you are ready to update your system, select the “update system” toggle.
Once again, version information will be shown. If the latest firmware is newer
than the installed one, you can start the update process. Please note: follow
the update instructions carefully and keep your MAN301R both powered up and
connected to the internet during the entire process.
Power management
The MAN301R can be shut down and rebooted from the web interface instead of
using the physical power button. A confirmation for completing the action will
be required.
