PCM and DSD

Two competing formats are available in the form of PCM and DSD, both of which are used to store audio signals at very high resolution and quality. Each of these formats has its own specific advantages. A vast amount has been written about the relative merits of these two formats, and we have no intention of participating in the dispute, much of which is less than objective in nature. Instead we consider it our task to develop equipment which reproduces both formats as effectively as possible, and exploits the strengths of each system to the full.

Our many years of experience with both systems have clearly shown that PCM and DSD cannot just be lumped together; it is essential to treat each format separately, and take their specific requirements into account. This applies both at the digital and analogue level.

For this reason the MP 2500 R employs two separate digital sections and two D/A converter sections - each optimised for one format.

MP 2500 R and DSD

By its nature the DSD format involves a noise floor which rises above the range of human hearing as frequency rises. Although this noise floor is not directly audible, it does subject the treble units in the loudspeakers to a significant load. It is also possible for the high-frequency noise to cause distortion in many low-bandwidth amplifiers. The lower the DSD sampling rate, the more severe the inherent noise, and it cannot be disregarded, especially with the DSD64 format - as used on the SACD. As the DSD sampling rate rises, the high-frequency noise becomes increasingly insignificant, and with DSD256 it is virtually irrelevant. In the past it has been standard practice to apply digital and analogue filtering processes in an attempt to reduce DSD noise, but such solutions are never entirely without side-effects on sound quality. For the MP 2500 R we have developed two special techniques designed to eliminate the sonic disadvantages:

1.) The  True-DSD technique, consisting of a direct digital signal path without filtering and noise-shaping, plus our True 1-bit DSD D/A converter

2.) Analogue reconstruction filter with automatic bandwidth selection.

MP 2500 R and PCM

The PCM process makes extremely high-resolution sampling values available: up to 32 bits. However, the sampling rate of PCM is significantly lower than that of DSD, and the spacing in terms of time between the sampling values is greater. This means that it is extremely important with PCM to employ maximum possible precision when converting the high resolution into analogue signals. Here at  our answer was to develop quadruple D/A converters which provide a four-fold improvement in accuracy over conventional converters. A further very important aspect of PCM reproduction is to reconstruct the curve of the original analogue signal between the sampling points with great accuracy, since these points are much more widely spaced in comparison with DSD. To this end the MP 2500 R employs a polynomial interpolation process (BezierSpline interpolation) developed in-house at , which in mathematical terms delivers the smoothest curve for a given number of reference points (sampling points). The output signal generated by Bezier interpolation exhibits a very “natural” shape, devoid of the digital artefacts - such as pre- and postoscillation - which are usually produced by the standard oversampling process. More detailed information on this can be found in the chapter “Technical

description, oversampling / up-sampling”

DSP set-up option

Oversampling (OVS)

The MP 2500 R can exploit four different filter types offering different tonal characters:

 Oversampling FIR long is a classic FIR filter with an extremely linear

frequency response.

 Oversampling FIR short is a FIR filter with improved peak handling.  Oversampling Bezier / FIR is a Bezier interpolator combined with a IIR filter.

This process produces a result very similar to an analogue system.

 Oversampling Bezier is a pure Bezier interpolator – offering perfect “timing”

and dynamics.



Please refer to the Chapter 'Technical description - Digital filters / Oversampling' for an explanation of the different filter types.

DSP set-up option

Output phase

With particular instruments or voices the human ear is certainly capable of detecting whether absolute phase is correct or not. However, absolute phase is not always correctly recorded.

In this menu item the phase of the signal can be changed from normal to inverse phase and back.



The correction is carried out at the digital level, and has absolutely no adverse effect on sound quality.

General information

There are three types of SACD disc: single-layer, dual-layer and hybrid. The hybrid disc contains a standard audio CD layer in addition to a super audio CD.

An SACD should always contain a pure stereo audio track, but it might also include an area containing multi-channel recordings. However, there are a few examples which are pure multi-channel discs, i.e. without a stereo audio track. Since the MP 2500 R is designed to reproduce pure stereo sound only, it is not possible to play back multi-channel discs.

Setting the preferred layer

The MP 2500 R always tries to read the preferred layer first. If this is not available, the alternative layer is read in automatically.

Proceed as follows to set the preferred CD layer (SACD or CD):

 Open the disc drawer by a brief press on the  button.  Select the preferred disc layer (SACD or CD) using the  button on the

Playback Program

The MP 2500 R’s integral Bluetooth interface provides a means of transferring music wirelessly from devices such as smart-phones, tablet PCs, etc. to the MP 2500 R.



For a successful audio Bluetooth transfer from a mobile device to the MP 2500 R the mobile device must support the A2DP Bluetooth audio transfer protocol.

Selecting the Bluetooth Audio source

Briefly tap the  buttons on the front panel of the MP 2500 R, repeatedly if necessary, or the  button on the SRC1 remote control handset until the source BLUETOOTH is displayed on the screen.

Setting up audio transfer

Before music from a Bluetooth-capable device can be played through the MP 2500 R, the external device must first be registered to the MP 2500 R. As long as the MP 2500 R is switched on and no device is connected, it is always ready to receive. In this state the screen displays the message 'not connected'.

This is the procedure for establishing a connection:

 Start a search for Bluetooth equipment on your mobile device.  When it finds the MP 2500 R, make the connection to your mobile

device.

Once the connection is successfully established, the message on the MP 2500 R’s screen switches to 'connected to YOUR DEVICE'.



If your device requests a PIN code, this is always '0000'.



The procedure for establishing a connection can only be made if the Bluetooth source is activated (see chapter “Basic settings of the MP 2500 R”).



Due to the large number of different equipment on the market, we are only able to provide a general description for setting up the radio connection. For detailed information please refer to the operating instructions supplied with your device.

Playback functions

Information on the piece of music currently being played is displayed on the screen of the MP 2500 R if this function is supported by the device connected to the unit.

The behaviour and method of operating the connected mobile device are determined by the device itself. In general terms the function of the buttons of the MP 2500 R or the SRC1 remote control handset are as follows:

Start and pause playback

The  /  buttons on the remote control handset or the front panel are used to start and pause playback (PLAY / PAUSE function).

Stop playback

Pressing the  button halts playback.

Skipping tracks

A brief press on the  /  buttons during playback causes the device to jump to the next or previous piece of music within the current playlist.



Please note that many AVRCP-capable mobile devices do not support the controlling through the MP 2500 R. In case of doubt, please ask the manufacturer of your mobile device.

Operating the Bluetooth source

Controlling the MP 2500 R



The MP 2500 R can also be controlled from the mobile device (Start/Stop, Pause, Volume, etc.). To control the MP 2500 R the mobile device must conform to the Bluetooth AVRCP protocol.



Please note that many AVRCP-capable mobile devices do not support all the

MP 2500 R’s control functions. In case of doubt, please ask the manufacturer

of your mobile device.

NOTES



The MP 2500 R has been tested with a large number of Bluetooth-capable mobile devices. However, we are unable to guarantee general compatibility with all devices available commercially since the range of equipment is so wide, and the various implementations of the Bluetooth standard differ widely in some cases. If you encounter a problem with Bluetooth transfer, please contact the manufacturer of the mobile device.

The maximum range of a Bluetooth audio transfer is normally about 3 to 5 metres, but the effective range may be affected by a number of factors. To achieve good range and interference-free reception there should be no obstacles or persons between the MP 2500 R and the mobile device.

Bluetooth audio transfers take place in what is known as the “everyman

frequency band”, in which many different radio transmitters operate - including

WLAN, garage door openers, baby intercoms, weather stations, etc. Radio interference caused by these other services may cause brief dropouts or - in rare cases - even failure of the connection, and such problems cannot be excluded. If problems of this kind occur frequently in your environment, we recommend that you use the Streaming Client or the USB input of the MP 2500 R instead of Bluetooth.

By their nature, Bluetooth transmissions always involve data reduction, and the attainable sound quality varies according to the mobile device in use, and the format of the music to be played. As a basic rule the maximum quality of music which is already stored in a data-reduced format, such as MP3, AAC, WMA or OGG-Vorbis, is worse than with uncompressed formats such as WAV or FLAC. For the highest reproduction quality we always recommend the use of the Streaming Client or the USB input of the MP 2500 R instead of Bluetooth.

General Information on D/A Converter Operation

The  MP 2500 R can be used as a high-quality D/A converter for other devices such as computers, streamer, digital radios etc. which are fitted with poor-quality converters or no converter at all. The MP 2500 R features two optical and two electrical S/P-DIF digital inputs on the back panel to allow this usage. A USB-DAC input on the back panel permits to use the MP 2500 R as D/A converter for computers.



You can connect devices with electrical co-axial or optical light-pipe output to the digital inputs of the MP 2500 R. At the optical inputs Digital In 3 and Digital In 4 the MP 2500 R accepts digital stereo signals conforming to the S/PDIF norm, with sampling rates of 32 to 96 kHz. At the electrical co-axial inputs Digital In 1 and Digital In 2 the range of sampling rates is from 32 to 192 kHz.

At the USB DAC IN input the MP 2500 R accepts digital PCM-encoded stereo signals with sampling rates of 44.1 to 384 kHz (32-bit) and DSD data with sampling rates of DSD64, DSD128, DSD256 and DSD512.

If you wish the MP 2500 R to convert audio files from a Windows PC connected to it, you must first install driver software on the computer (see the chapter entitled ‘USB DAC operation in detail’). If you are using a computer running Mac OS X 10.6 or higher no drivers are necessary.

D/A Converter Operation

Selecting a D/A Converter Source

Select the MP 2500 R as listening source on your amplifier. Choose the digital input to which you have already connected the source

device which is to be played by pressing the source button  on the front panel or the  button or the  button (for the USB DAC IN) on the SRC1 (repeatedly if necessary).

As soon as the source device delivers digital music data, the MP 2500 R automatically adjusts itself to the format and sampling rate of the signal, and you will hear the music.

The drivers required, together with detailed installation instructions including information on audio playback via USB, are available for downloading from our website at

http://www.ta-hifi.com

Settings

A number of system settings have to be altered if you wish to operate MP 2500 R with your computer. These changes must be made regardless of the operating system. The installation instructions provide detailed information on how and where the settings are to be changed.

Notes on software



By default, the operating systems listed above do not support ‘native’ music

playback. This means that the PC always converts the data stream to a fixed sample rate, regardless of the sample rate of the file to be played. Separate software is available - e.g. J. River Media Center or Foobar - which prevents the operating system converting the sample rate. The installation instructions included in the driver package contain further information on audio playback via USB.

Notes on operation



To prevent fail functions and system crashes of your computer and the playback program, please note the following:

 For Windows OS: Install the driver before you use the MP 2500 R for the

first time.

 Use only drivers, streaming methods (e.g. WASAPI, Directsound) and

playback software which are compatible to your operating system and between each other.

 Never connect or disconnect the USB connection while the system is

running.

Firmware update

Compact Discs (CD) are digital data media which need to be handled carefully. These are the basic rules:

 The surface of a CD should only ever be cleaned with a soft dry cloth. Never

wipe it in a circular motion, i. e. along the tracks.

 Never use petrol, paint thinners, disc cleaners or similar materials on

compact discs.

 CDs must be handled carefully in order to avoid serious damage to the

surface. Severely scratched surfaces, writing on the disc or applying selfadhesive labels may result in the CD player being unable to read the data.

 CDs should not be heated or bent. This means that they should be stored in a

position and attitude which meet these requirements.

R2 LINK

Control interface for remote control of  systems.

Field strength

The electrical field strength is a measurement of the level (strength) of the radio signal supplied by the antenna. In general terms, the higher the field strength of the tuned station, the better the reception quality. Signal field strength is determined primarily by the following factors:

1. Distance from radio transmitter

2. Obstacles (mountains etc.) between transmitter and receiver

3. Transmitter output power

4. Quality and direction of the receiver antenna system. Point 4 is of crucial importance here. It is impossible to obtain good reception

with a poor aerial system. Your specialist  dealer will be glad to advise you on the subject of installing

or improving your aerial system, taking your specific local reception conditions into account.

= Frequency Modulation

All FM radio transmitters use the 'FM' method of modulation. This technology provides maximum possible sound quality and interference suppression.

Cable Network

When the MP 3000 HV's tuner was being developed the requirements of the European cable network were given high priority. The tuner copes very well with excessive signal levels, and its high selectivity avoids many of the problems involved with cable operation, without any reduction in reproduction quality.

MIX

In MIX-Mode (Shuffle) the titles of a CD or the titles of a program are played back in a random order.

Muting =

Hiss suppression

The MP 2500 R features automatic hiss suppression which cuts out the annoying hissing sound between radio stations, and suppresses very weak stations which cannot be received with reasonable quality.

Preset

= station memory

The MP 2500 R can store all the settings for stations, any of which can be recalled simply by pressing a button.

RDS

= Radio Data System

Many radio stations broadcast supplementary digital information simultaneously with the programme. The MP 2500 R is equipped with an RDS decoder, and displays the station name of RDS transmitters in plain text on its alpha-numeric screen. This is a great advantage when searching for particular stations.

SINGLE CD

A Single CD‘ is a CD with smaller diameter and a shorter play time. The

MP 2500 R can play back CD singles. Please insert these discs into the depression at the center of the disc tray.

Standby

The MP 2500 R can be switched on from the Standby state from the remote control handset.

Seek threshold

The seek threshold is the minimum field strength value at which the automatic station search process halts. It is set at a level which ignores very weak transmitters.

Glossary / Supplementary Information

Oversampling

The audio data on for example CDs is stored at a sampling rate of 44.1 - i. e. for each second of music 44.100 sampled values are available for each channel. In the MP 2500 R the audio data read from the CD is „multiplied“ to a higher sampling rate (352,8 kHz) before it is converted back into analogueue music signals. This process delivers a very much better, more finely graduated signal to the converter, which can then be converted with correspondingly higher precision. The raised sampling rate is a calculating process for which there are many different mathematical methods. In almost all digital audio devices which exploit the advantages of increased digital sampling rate a process known as a FIR filter is employed for this purpose. At  we have been carrying out research for more than ten years, aimed at improving the oversampling process, because the standard FIR method has one drawback to set against its indisputable advantages: it adds small pre- and post-echoes to the music signals. At  we have developed mathematical processes (known as Bezier polynomial interpolators) which do not share this disadvantage. For this reason they should sound better and more natural than the usual standard process. Since the calculating procedure employed by us is considerably more complex than the standard method, the MP 2500 R features a highperformance digital signal processor (DSP) which carries out the over-sampling process with immense precision (56 bit) using special algorithms developed by . The freely programmable DSP which we use is capable of carrying out the oversampling process using any method of calculation. For this reason we have implemented a slightly modified Bezier process (filters 3) in the MP 2500 R in addition to the pure Bezier process (filter 4), together with two variants of the standard process (filter 1 and filter 2). For more information on the different processes please refer to the next section. You can switch between the various algorithms, then decide for yourself which of the filters gives the results you prefer.

Oversampling 1 (Standard FIR Filter) The long FIR filter is the standard oversampling process in digital technology,

offering extremely linear frequency response, very high damping, linear phase characteristics and constant group delays. The disadvantage is the pre- and post-echoes which are added to the signal. These „time range errors“ tend to

affect the music signal’s dynamics, precision and naturalness, and reduce

spatial orientation.

Frequency response and transient characteristics of the long FIR filter

Technical description

Digital filters / Oversampling

Oversampling 2 (Impulse optimised filter) Shortening the filter (lower coefficient) reduces the time range errors, albeit

combined with a slight loss of linearity in the frequency range and damping performance.

Frequency response and transient characteristics of the short FIR filter

Oversampling 3 (Bezier-interpolator plus IIR-filter)

In this process an ideal Bezier interpolator is combined with what is known as an IIR filter. This eliminates the problematic pre-echo of the FIR method. This

process produces highly „analogueue“ system characteristics, with a sound

quality and measured performance similar to those of good analogueue record players.

Frequency response and transient characteristics of the Bezier interpolator plus IIR filter

Oversampling 4 (pure Bezier interpolator)

This process delivers a perfect reconstruction of the original music signal. It exhibits no pre- or post-echoes of any kind, and does not add coloration or timing errors to the original signal. In sonic terms this method offers an impressive blend of naturalness, good dynamics and accuracy.

General information

The Switch ensures that the individual components within a network are connected correctly. This is only possible if it can identify each device within the network unambiguously; this is the reason why every component is assigned a form of “house number” (IP address). The IP address consists of four number blocks each containing three digits separated by dots (e.g. 192.168.1.1).

Each of the individual number blocks may contain values between 1 and 254 (the values 0 and 255 are reserved for certain special functions, and should therefore not be used). However, if the network is to operate reliably, the network owner should only select addresses designed for home network use i.e.: the first two number blocks should always be 192.168.xxx.xxx; the third block can be selected without restriction within the above limits (but should be the same for all devices on the network), and the fourth block must distinguish each device uniquely (e.g.: MP 2500 R 192.168.001.001, NAS:

192.186.001.002, PC: 192.168.001.003, ...). If this local network is to include Internet music sources (Internet radio) as well

as physical devices, then the  MP 2500 R must have access to the Internet. This facility is provided by a device such as a router with connection to the DSL network. This router is also a constituent part of the network, and is assigned its own IP address. The  MP 2500 R must also be informed of the address of the router (Gateway) to enable it to gain access to the outside world.



Please ensure that the first three blocks of the Device IP, Gateway IP and DNS 1 share the same address space (e.g. 192.168.0.xxx). The fourth block assigns a unique address (house number) to the components in the local network. This number must not be present more than once in the local network. The Device IP mask should always be assigned the address 255.255.255.0.

DNS

The Domain Name System (DNS) is one of the most important services on the

Internet. Its primary task is to convert “Internet addresses”, such as

www.taelektroakustik.de, into the associated IP address. In most home networks the router carries out the DNS function. If you decide to configure your network manually (without DHCP), then simply enter the address of your router as the DNS address when configuring the network.

Ethernet-LAN

Wired network. Interference-free network technology, with the drawback of having to deploy a network cable.

Gateway

The computer or router in your network which is responsible for managing data traffic between your home network and the outside world (i.e. the Internet).

Client

Network device which obtains data from the network, decodes it and converts it into, for example, analogueue music signals which can then be reproduced via an amplifier and loudspeakers. Streaming Clients also contain functions for displaying media content, and for navigating on the Internet or servers.

DHCP

DHCP is an abbreviation of Dynamic Host Configuration Protocol. The primary purpose of DHCP is to enable Clients to obtain your network configuration automatically from a server or router.

IP-Adress

Network address. Each device in the network requires an IP address at which it can be accessed, and by which it is unambiguously identifiable. No individual network address may be present more than once. This is important if you are entering network addresses manually. If the addresses in your network are assigned by DHCP, you do not need to worry about IP addresses at all, as the DHCP server manages the addresses automatically without your intervention.

Network Terminology

NAS (Network Attached Storage)

Network storage facility. This is generally a very large-capacity (> 200 GB) storage device to which other devices have access. If the NAS server includes a UPnP-AV server service, then the MP 2500 R has access to media files stored on the NAS, and can play them back.

Powerline-LAN

In a Power-Line LAN data is transferred via the existing mains power cabling. Devices known as “Power-Line modems” are required at the transmitting and receiving end. In most cases Power-Line offers relatively problem-free data transfer with adequate data rates for audio streaming. We recommend PowerLine modems with bit rates of 85 or 200 Mbit/s.

Proxy server

A Proxy or Proxy server is a computer in the network which is capable of carrying out data transfers faster and more efficiently, and can increase security through the use of access control mechanisms. Most home networks do not include a proxy server. In this case there is no need to enter a Proxy address when configuring the MP 2500 R network.

Router

Central network device which creates and manages the connections between the network devices. In most networks the router also assumes the function of Gateway to the outside world.

Server

Network device which provides data and services for other devices in the network. For example, a UPnP-AV server typically stores audio / video data, and makes it available to other devices (the Streaming Clients). Many UPnP-AV servers also offer functions such as cataloguing, and easy identification of media content using criteria such as artiste, album name, genre, etc.

UPnP-AV

Network protocol that makes media files available on the home network. On PCs and NAS storage devices a UPnP-AV server software must be

installed to enable the MP 2500 R to access media files stored on these devices.

Examples for UPnP-AV server software compatible with the MP 2500 R: Windows:  Twonky Media Server

WLAN (also W-LAN, Wireless LAN)

Radio network. The network is connected by means of radio waves operating in the 2.4 GHz frequency band. Radio networks are easy to install as no cables have to be deployed, but they are often problematic and unreliable - especially when the transmission distances are substantial. Power-Line networks, which can also be installed without separate cabling, are a better choice in many situations. In every case the deployment of a network cable is the most reliable and problem-free technology for data transfer.

Compatible hardware and UPnP servers

The marketplace offers a vast number of routers, NAS devices and USB hard discs made by a very wide range of manufacturers.  equipment is generally compatible with other makes of machine which bear the UPnP label. A list of devices which  has checked for compatibility can be found on the Internet at: http://www.ta-hifi.de/fileadmin/software/e-serie/MP_HW_KOMP.pdf

Machine does not switch on (Display does not light up).

Cause 1:

Mains leads not plugged in correctly. Remedy:

Check connection, push connector in firmly.

Whistling or whispering noises from the speakers.

Cause:

The antenna lead is routed too close to a mains, remote control or audio signal cable.

Remedy: Move the leads so that they are spaced well apart. Use the domestic (loft or outside) antenna or a cable connection.

The RDS station name does not appear in the display.

Cause 1: The station is not broadcasting RDS information.

Cause 2:

Reception is poor, interference is severe, or the field strength (signal strength) is low.

Remedy: Select only those stations which can be received with a strong signal: hiss-free and without interference.

The unit can be operated normally, but very few stations or none at all can be picked up.

Cause:

The antenna system or antenna cable is faulty. Remedy:

Check the antenna lead for good contact at the antenna socket (at the wall) and in the back of the tuner. As a test, try using the system with a trailing antenna. If you can now receive stations reasonably well, we recommend that you call out an expert antenna technician to check your antenna system.

The screen displays the message 'No Disc' when you close the CD drawer.

Cause 1:

CD not inserted correctly. Remedy:

Place CD centrally in the drawer, printed face up.

Cause 2: CD dirty.

Remedy: Clean disc and insert again.

Cause 3: CD damaged in the Table of Contents (TOC) area.

Remedy: No remedy; the CD is unusable.

Cause 4: The CD player has become very cold (e. g. in transit) and condensation has formed on the laser sensor optics.

Remedy: Allow the unit to warm up for about an hour in a warm, well ventilated location.

Trouble shooting

Many problems have a simple cause and a correspondingly simple solution. The following section describes a few difficulties you may encounter, and the measures you need to take to cure them. If you find it impossible to solve a problem with the help of these notes please disconnect the unit from the mains and ask your authorised  specialist dealer for advice.

Tuner

CD player

CD playback stops or 'jumps'.

Cause 1:

CD damaged or dirty. Remedy:

Clean CD. A damaged CD cannot be repaired!

Cause 2:

The CD uses a copy protection system which does not conform to the CDAudio standard (Red Book Standard)

Remedy: Take back the CD to the dealer and ask for a proper CD according to the general CD standard.

Loud humming noise from the loudspeakers.

Cause:

Poor contact between the Cinch plugs and sockets, or a faulty Cinch cable. Remedy:

Please check all connections and cables thoroughly.

The streaming client cannot connect to a network.

On the display the indication Cannot connect to network...' is displayed.

Cause 1 (cable LAN):

Network cable not properly connected Remedy:

Connect network cable, check connection to router

Cause 2 (wireless LAN):

WLAN antenna not connected or placed in a location with bad reception quality Remedy:

Connect WLAN antenna properly and find a location with good reception quality.

Set the transmission power output of your WLAN router to maximum. Try to establish a network connection first in a location close to the WLAN

router. If this succeeded try to connect to WLAN from a more remote location. Experiment with antenna position and try to find a location with better reception quality.

Cause 3 (wireless LAN):

WLAN reception quality bad (low field strength). Possibly too much attenuated by walls/ceilings on the transmission path.

Remedy: Optimize location of receiver and transmitter antennas.

Alternative:

If transmission problems persist a so called ‚Power Line‘ network might be good alternative to establish a good and stable network connection.

The best, safest and most secure network however will always be a cable LAN network.

Cause 4:

Network parameters not properly configured. Remedy:

Configure the network parameters correctly (see chapter 'Network

configuration').

Cause 5 (operation without network connection):

For proper operation the MP 2500 R needs at least one properly connected network device. This can be a LAN or WLAN network or a USB storage device.

Remedy: If the MP 2500 R shall be operated without network (LAN / WLAN) please connect at least a USB stick.

The message 'No Data Available' is displayed

Cause:

The music file on the storage device or on the music server was deleted or the internet radio station is not available at the moment.

Remedy: Choose another music title or radio station. If the station or title is not available any more it should be deleted from the Favourites List (if stored there).

Streaming Client

The message 'network problems –

restarting' is displayed

Cause:

Network problems in your home network or on the internet occurred; the connection was interrupted.

Remedy: When encountering a network problem or interruption the MP 2500 R will restart the network communication. After re-start please choose a music title or internet radio station and start playback.

Transmission interruptions occur when listening to internet radio stations.

Cause 1:

The capacity of the internet radio station‘s server is at its limit.

Remedy: Choose a different station.

Cause 2: Network problems occurred.

Remedy: Check your network (see above).

Some internet radio stations cannot be received

Cause:

The internet radio station has been switched off, it transmits only at certain hours of the day or it has changed its internet address.

Remedy: Try to get information from the website of the station regarding transmission hours and internet address (URL).

Try to establish a connection to the station at a later time.

Bad sound quality at certain internet radio stations

Cause:

The station transmits with a low audio bandwidth (low bitrate). Remedy:

Use stations transmitting at least at 128 kBit/s. This is the lowest recommended bitrate for adequate sound quality. For good sound quality we recommend high bitrates like 320 kBit/s

USB Storage device is not recognised

Cause 1:

The storage device (especially USB hard discs without separate power supply) draws more electrical current from the USB interface than is permitted by the USB standard.

Remedy: Only use USB storage devices that conform to the USB standard or use

storage devices with own power supplies.

Cause 2:

The storage device is not formatted with an appropriate file system. Remedy:

The MP 2500 R accepts storage devices with FAT16 or FAT32, NTFS, Ext2, Ext3, Ext3 file systems.

Note:

For big music archives we recommend to use a NAS (network attached storage) device with a UPnP-AV server to which the MP 2500 R will connect via your home network.

Problems occur with highresolution audio formats (HD audio) (FLAC and WAV).

Cause:

The MP 2500 R is receiving audio data via a WLAN connection. WLAN connections do not provide reliable quality, and in most cases are not adequate for HD audio.

Remedy:

If you want to play back HD audio formats via a network connection, please use a LAN cable network.
