Microphone emergency setting

In the case of an external emergency signal muting the unit’s outputs, an internal jumper can be set to either mute the connected microphones (”off”) as well or to keep them active (so that aside of a emergency message broadcasted, additional instructions can be given by a local microphone – “on”).To make the setting, locate and set the jumper on the front PCB as shown below.

Antenna mounting

To achieve acceptable Bluetooth reception distances, the product must be operated with an antenna in line-of-sight to the paired device. Connect the supplied Bluetooth antenna to the front panel antenna socket (35).

Notes on files, folders and data conventions

The media player section built into this unit is a hardware player and as such subject to various restrictions, which are useful to be aware of:

• Media Memory The player only works with USB sticks up to l6 GB of size which are formatted in FAT32 file system and contain a maximum of 2000 files.The player does NOT support larger memory sizes, external hard disks or any media with NTFS formatting.
• Media File The player’s replay ability from solid state memory media is limited to MP3 files in MPEG l Layer 3, MPEG 2 Layer 3, MPEG 2.5 Layer 3 standard, with sample rates of l28/l60/l92/224/256/320 kbps + VBR. Any other files existing on the solid state memory media will be ignored and are not available for replay.
• File/Folder The player only allows a two-layer folder structure on the solid state media memory, meaning a root layer and a folder layer, but not any cascaded folder-in-folder structures. Such subfolders will be ignored and their content is not available for replay. Playable files located in the root layer are displayed in a folder named “ROOT” although this folder does not physically exist on the solid state memory media.
• Folder Folders are displayed in the sequence of their creation dates on the solid state memory media. If a specific sequence is needed, then the folder shall be created in this sequence on the memory media before copying any MP3 files into them.
• File Files are sorted alphanumerically, but due to file system limitations, the sorting is limited to the first 8 digits. This may in some cases – where the first 8 digits are identical – lead to a random-looking, not alphabetical sorting sequence of files.
• File system In order to allow relatively quick access to the file directory during navigation, the player loads a copy of the file directory into its own memory upon insertion of the solid state memory media. This loading process requires some time, during which the display shows a countdown. The time required is about 4 seconds per 100 tracks with a maximum of 2000 tracks (meaning Max. 80 seconds loading time).
• Displayed File/Folder MP3 files are displayed with the first 30 digits of their file names in a scrolling manner; digits exceeding the first 30 will be ignored. Note that the display data is the file name and NOT the ID3 tag of the file. Folders are displayed with the first l0 digits of their names, any exceeding digits will be ignored.

Operation

A. Connections

For connecting this unit to AC mains, please follow the instruction given in the “unpacking” section.

For making audio signal connections, always remember that good and reliable connections are a basic requirement for good sound and reliable operation. Bad soldering of cables can result in intermittent audio signals or temporarily lost ground connections, hence always use good cables. In case of doubt about making proper connections, please see check the standard pin assignments required for proper operation in the following section of this manual.

B. Powering up

Following a proper power-up sequence protects your equipment – specifically speakers – and your ears. Follow the below procedure:

• Turn down all output volume controls of any equipment in your audio system.
• Switch on your audio sources first (Tuners, CD Players, PC’s with soundcards,Tapedecks, etc.)
• Switch on this unit, then any connected amplifier
• Turn up the audio level on your sources if such controls are provided.
• Set the stereo main volume control of this unit to a low level.
• Make adjustments to all volume settings as needed.
• For switching off, follow the inverse sequence

C. Use

Apart from using good equipment, good sound comes from using it correctly. Level setting mistakes are one of the common reasons why even good equipment may not perform as desired. For setting levels, please be reminded that two guidelines need to be followed:

• Avoid distortion by leaving some Never overrun any audio-equipment’s inputs. Level meters and displays allow you to make sure that signals do not enter critical levels.
• Avoid unnecessary amplification by using as little attenuation as For example, if you turn down the input gain of a mixer to minimum, and then increase the main output of the mixer to maximum to drive your amplifier properly, you will create unnecessary noise, as you first dispose of some already existing signal level, and then later apply amplification (tainted with noise) to make it up.

Obviously, these two requirements are marking a levelling window that the operator must match to achieve a good sound with as little distortion and noise as possible.

WARNING – HEALTH RISK Excessive volume levels on headphones or other sound systems may cause hearing damage. Always turn the volume control to minimum when you switch the unit on, and avoid prolonged exposure to sound pressure levels exceeding 90dB.

Bluetooth Replay

The MX141M has built-in Bluetooth module connectivity.

To connect a Bluetooth source like a smartphone or tablet to the MX141M, follow the procedure below:

• Press the SOURCE button (34) until the display shows “AUX-BT”
• Activate Bluetooth on the source device (phone, tablet)
• Search /(Scan) for Devices on the source device
• Select “Bluetooth Board” and confirm connection request
• Wait for single beep from the MX141M
• The devices are now paired and the MX141M is ready to receive audio via Bluetooth

Note: Only one device can connect – once a device is connected, the BT board will not appear on the device scan of any other device.

To disconnect, simply do the following:

• Tap on existing Bluetooth connection in your source device
• Wait for dual-tone beep from the MX141M
• The devices are now unpaired and the MX141M is ready to be paired with a different device.

Please note that the maximum distance of operation between your source device and the MX141M depends on many factors, such as other interfering signals, the position of the MX141M in the room, the position of the source device in the room, and the antenna/Bluetooth hardware design of the source device. While Bluetooth should work as a rule-of-thumb up to 10 m distance, certain hardware combinations, geometrical setups or the presence of interfering signals can reduce this significantly. The manufacturer of this device does not grant any specific operating distance and cannot take any liability for dropouts. For critical applications, we recommend to avoid wireless replay.

Connections

This unit uses the connector types below, for which the pin assignment must comply with the following specification. Balanced connections are to be preferred over unbalanced connections where applicable and feasible. Avoid unbalanced connections exceeding 2m of cable length.

Maintenance and Warranty

While we have chosen the best components to make this product as rugged and reliable as possible, some parts in audio products (potentiometers, faders, switches) are subject to wear which is a matter of operation cycles, and not of time. While providing a full time-based warranty according to the country’s of purchase requirements on the function of the electronic circuitry, we hence have to limit the warranty on such electro-mechanical parts to 90 days from the date of purchase.

In many cases, malfunction of electro-mechanical parts occurs due to dust contamination, which may require cleaning of such parts. As the inside of such parts is not accessible, a common practice is to use cleaning fluids in the shape of sprays. Please be reminded that many of such fluids contain chemicals which may wash away the dust but at the same time corrode or damage contact surface and may cause cosmetic damage to other parts.We hence explicitly exclude any claims for exchange of damaged part due to mechanical or chemical impact.
