PLUG FITTING INSTRUCTIONS (UK ONLY)

The cord supplied with this appliance is factory fitted with a UK mains plug fitted with a 5 amp fuse inside. If it is necessary to change the fuse, it is important that a 5 amp one is used. If the plug needs to be changed because it is not suitable for your socket or becomes damaged, it should be cut off and an appropriate plug fitted following the wiring instructions below. The plug must then be disposed of safely, as insertion into a mains socket is likely to cause an electrical hazard. Should it be ecessary to fit a 3-pin BS mains plug to the power cord the wires should be fitted as shown in this diagram? The colors of the wires in the mains lead of this appliance may not correspond with the colored markings identifying the terminals in your plug. Connect them as follows:
The wire which is colored BLUE must be connected to the terminal which is marked with the letter ‘N’ or colored BLACK.
The wire which is colored BROWN must be connected to the terminal which is marked with the letter ‘L’ or colored RED.
The wire which is colored GREEN/YELLOW must be connected to the terminal which is marked with the letter ‘E’ or colored GREEN.
If a 13 amp (BS 1363) plug is used, a 5 amp fuse must be fitted, or if any other type of plug is used a 5 amp fuse must be fitted, either in the plug or adaptor or on the distribution board.

Connections

LOUDSPEAKERS
Check the impedance of your speakers. You can use types with an impedance of 8 Ohms.
The red-colored speaker terminals are positive (+) and the black speaker terminals are negative (-). Make sure correct polarity is maintained at each speaker connector or the sound can become weak and “phase” with little bass.

USING BARE WIRE CONNECTIONS
Prepare the speaker cords for connection by stripping off approximately 10mm (3/8”) or less of the outer insulation. More than 10mm could cause a short circuit. Twist the wires tightly together so there are no loose ends. Unscrew the speaker terminal, insert the speaker cable, tighten the terminal and secure the cable.
Note: All connections are made using a standard loudspeaker cable.

USING BANANA PLUGS
We recommend using Banana plugs with our units to establish a secure connection and ensure there are no loose strands of wire that may cause unwanted noise or interference.
Once you have stripped the outer insulation of the cable and twisted the wires as indicated above, securely connect these to your banana plugs, remove the dust cap from the end of the speaker terminal and push the plugin as far as possible without applying excessive force.

BASIC CONNECTION
The diagram below shows the basic connection of your unit to a CD player, turntable, and a pair of loudspeakers.

SPEAKER B CONNECTIONS
The Speaker B connections on the back of the amplifier allow for a second set of speakers to be used (i.e. speakers located in another room).
The Speaker A/B button on the front panel and remote control allows the two sets of speakers to be toggled on and off. Refer to the Front Panel or emote Control section of this manual for more information on the Speaker A/B operation.
Either A or B or both A and B may be selected for use.
Note: When using two pairs of speakers, use speakers with a nominal impedance of 8 ohms each.

BI-WIRE CONNECTIONS
If your loudspeakers are equipped with two sets of terminals, then it is possible to connect them in the bi-wire configuration. Bi-wiring sends the bass and treble frequencies down separate speaker cables, resulting in a clearer, more focussed sound.

Note:
– Speakers A and B must both be selected for this type of connection to work.
– Remove the bi-wire link on the speaker terminals before connecting. Refer to your speakers’ manual for more information.

Aerials

Note: The AXR100D is supplied with a temporary aerial for initial use. For permanent use, outdoor aerials are highly recommended.
DAB/FM AERIAL
Extend and move the aerial until you get the best reception.
AXR100D has an F-type screw connection and the attached aerial can be removed and replaced with an optional outdoor DAB & FM aerial if required.
To remove the aerial, feed the supplied aerial key through the aerial and turn the key counter-clockwise.

Troubleshooting

THERE IS NO POWER
Ensure the AC power cord is connected securely.
Ensure the plug is fully inserted into the wall socket and is switched on.
Check fuse in the mains plug or adaptor.
Check the power is on at the front of the unit.
THERE IS NO SOUND
Check the correct input is selected.
Check that the speakers are connected correctly.
If using the tuner, check aerial connections, and an available station is selected.
Check the unit is not in mute mode.
Check the Speaker A/B configuration matches your speakers.
THE SOUND IS DISTORTED
Check aerial connections and placements.
Check speaker connections.
THERE IS A HUM COMING FROM THE SPEAKER
Ensure that all cable connections are secure, particularly ground/shield connections for turntables.
THERE IS UNWANTED BACKGROUND NOISE AND
INTERFERENCE
Move the unit away from other electrical equipment that is likely to cause interference.
Re-orientate the aerial.
Ensure that all cable connections are secure, particularly ground/shield connections for turntables.
THE REMOTE HANDSET WILL NOT FUNCTION
Check that the batteries have not expired.
Ensure that nothing is blocking the remote sensor.
OVER-TEMPERATURE PROTECTION
The unit has an over-temperature and shutdown protection. If the unit is continuously used for a long period and overheats, the unit will shut down. Leave the unit ‘Of’ for  10 minutes to cool down, then turn the unit on to continue listening. If the problem persists, then the unit is being overdriven. Reduce the volume level, and ensure the unit is in an open ventilated area to resolve the problem. The use of two pairs of speakers which are less than 8 Ohms can cause overloading and is not recommended.
