IMPORTANT SAFETY PRECAUTIONS

• Please read the instruction manual carefully before use and keep it in a safe place.
• This device is only intended for use with 230V / 50Hz AC voltage.
• Only operate the device at an ambient/room temperature between 5^ and 40^ .
• Make sure there is sufficient ventilation for the device. There must be a minimum gap of 10cm between objects to the side, to the rear and above the device.
• The ventilation slots should not be covered by any items (e.g. curtains, newspaper, etc.) in order to ensure sufficient ventilation for the device. Please do not position any sources of heat, such as radiators, ovens, naked flames or other devices that generate heat in close proximity to the device.

Heating phase of the tube: WARMUP This lasts for around 20 seconds after the device has been switched on.

• Selected audio input:
  CJ TUNER PHONO RUX TAPE FRONT
  Volume muting:
  VOL 15
  MUTING
• Menu settings (see page 10).

5 LINE-IN (FRONT)

3.5 mm stereo input jack for an auxiliary audio device (e.g. MP3 player, etc.).

6 VOLUME/MENU

Turn: For adjusting the overall volume of the music.

Press: Launches the menu for adjusting tone and for configuring the inputs. Turning the VOLUME knob navigates through the menu.

7 HEADPHONES

INITIAL OPERATION

• Place the MA 400 on an even surface. Observe the relevant clearance gaps as specified under "Important safety instructions".

IMPORTANT: Do not place any objects on top of the device (magazines, CD/record cases, etc.). The ventilation slots located on top of the device must be unobstructed at all times!

• Connect your speakers:

The stereo speakers (impedance of 4 to 8 ohms) are connected to the rear as follows:

Only use high-quality audio speaker cables with a conductor cross section of min. 1.5 - 2.5mm^2 . Strip approx. 10mm from the cables and twist the ends. Loosen the terminal screws one after the other and insert the stripped ends into the holes. Re-tighten the terminal screws. Make sure you pay attention to the correct polarity.

You can also use prefabricated cables with 4mm banana plugs or forked fittings.

Also observe the operating instructions for the speakers you are using.

• Connect your audio sources to the analogue connections.
• Connect the supplied mains cable to the rear and then insert the other end into a 230V socket.
• Actuate the on/off switch on the rear side, the device is now in the standby mode.
• Now switch on the device using the remote control or with the ON/STBY key on the front.
• When the tube has heated up the device is ready for use.
• Select your desired audio source using the input selector switch.

THE MA 400'S MENU

The tone and the inputs' input sensitivity may be comfortably adjusted via a menu.

• The menu is launched with the MENU key on the remote control or by pressing the volume control on the front.
• The menu may be navigated and settings changed with the VOLUME keys on the remote control or by turning the volume control.
• The individual menu items may be confirmed with the MENU key on the remote control or by pressing the volume control.

The following settings are possible:

• Bass adjustment:

Select BASS in the menu. Bass playback may be ramped either up or down in five steps.

• Treble adjustment:

Select TREBLE in the menu. The treble setting may be ramped either up or down in five steps.

Balance adjustment:

Select BALANCE in the menu. The stereo balance may be adjusted either to the right or left in ten steps.

• Loudness (aurally compensated volume correction):

Select LOUDNESS in the menu. The function may now be activated or deactivated.

• Input sensitivity:

Select INPUTGAIN in the menu. Now the input sensitivity for the currently selected input may be increased in four steps. This enables you to adapt audio sources with lower output levels to other audio sources.

The RESET menu item will restore the basic settings (all tone settings to 0, loudness function off and input sensitivity for all inputs to 0 dB).

You can leave the menu via EXIT.

TUBE REPLACEMENT

The device has a high quality preamplifier stage which is equipped with a tube. The tube has a very long service life when used under normal operating conditions (min. 20,000-50,000 hours).

If it is necessary to replace the tube, please refer to a specialist dealer.
