INITIAL OPERATION

• Place the MA 900 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 – 2.5 mm². Strip approx. 10 mm 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.
• 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.

CONNECTING THE DEVICE TO A BLUETOOTH AUDIO SOURCE

Select Bluetooth input. If you have previously connected a Bluetooth device, the MA 900 will automatically attempt to re-establish a connection with this device. If this is the case, you may be required to manually reconfirm the connection on the source device.

If a connection has not already been made or the connection cannot be re established, the MA 900 will automatically activate the ‚pairing mode‘. „BT“ will flash on the display.

Now activate the Bluetooth mode on your source device. The MA 900 will appear in the list of Bluetooth devices as „MA 900“. If it is not displayed in the list, set your source device to search for Bluetooth devices manually and make sure that the MA 900 has been switched to the pairing mode.

Depending on the source device, you may be asked whether the password is to be accepted during the pairing procedure. You can confirm this by simply pressing „Accept“. If you are still asked for a password, use the default passwords „0000“ or „1234“. If you are asked if you want to establish a connection after pairing, please select „Yes“. When the device has been paired and connected successfully the „BT“ indicator will illuminate continuously.

The MA 900 supports the „Qualcomm® aptX™ HD“ high quality audio transmission standard. If your source device also supports this standard, „Qualcomm® aptX™ HD“ will be selected automatically as the transfer mode when establishing a Bluetooth connection.

AUTO STANDBY FUNCTION

The unit has an auto standby function that automatically switches the device to standby mode around 3 1/2 hours after the last time it was operated (via the controls on the unit or via the remote control).
This function implements an EU energy-saving regulation (1275/2008 EC), reducing power consumption if the device is accidentally left turned on after use.

This function can be deactivated as follows:
Press the DIM button on the device for around 5 seconds. APO MODE OFF appears in the display.
Pressing the button again for around 5 seconds activates the function again.
APO MODE ON then appears in the display.
