ATTENTION: Connect the amplifier to the AC adapter BEFORE connecting the AC adapter to the power outlet to avoid sparks due to rush-in

Connect the amplifier to regular passive loudspeakers via the supplied speaker cable. Observe the correct polarity when connecting the speakers.

ATTENTION!

Do not connect the amplifier to active speakers or active subwoofers!

Use the Model 400 Wireless Audio receiver to connect to active speakers.

Step 3

Placing the amplifier

For best reception, we recommend that the amplifier be placed within the line of sight from the transmitter. If possible, the amplifier should be placed right side up with its front toward the transmitter.

Example 1 below shows the optimum placement of the amplifier. If no line of sight is possible, place the amplifier such that there is the minimum possible number of walls and obstacles between the transmitter and amplifier.

You can mount the amplifier vertically as shown in Example 2 by using the 2 screw openings at the bottom. In this case, the operating range is reduced compared to mounting the amplifier right side up.

The amplifier incorporates a directional antenna which prefers signals transmitted toward the front of the amplifier. Therefore, the front of the amplifier should always be facing toward the direction of the strongest transmitter signal.

Note: This product will not work properly from within an enclosed metal cabinet.

Troubleshooting

Problem Possible Cause Solut ion

No audio at amplifier Faulty AC adapter or faulty power outlet

Strong interference

Check the amplifier power supply.

Audio is distorted

Receiver audio level is too low

Audio drops out intermittently or crackles

Amplifier volum e control set too high

Lower the source audi o vol ume until clipping stops.

Problem

Transmitter range is extremely short

Possible Cause Solut ion

Strong interference In some cases, there may be strong interference preventing proper reception of the audio si gnal which can be caused by 5.8 GHz cordless telephones or 5.8

GHz wireless networks. Either eliminate the interference, l ocate the base unit of the cordless phone i n another room, set the wi reless network to use the 5.1 GHz frequency band rather than 5.8 GHz, relocate the transmitter, relocate or reori ent the amplifier to improve reception.

Too many obstacles Audi o will drop out if there are too many obstacles between the transmitter and the amplifier, try rel ocati ng the transmitter or receiver to improve reception.

IMPORTANT SAFETY INFORMATION

ATTENTION!

READ THESE SAFETY INSTRUCTIONS CAREFULLY AND

HEED ALL WARNINGS IN THIS MANUAL.

POWER SOURCE

To product malfunction, and to protect against electric shock, fire or personal injury, please observe the following:

• This product has been designed to work with 120-volt AC current using the supplied AC adapters. Connection to a line voltage other than that or use of non-compatible AC adapters may create a safety and fire hazard and may damage the product.

• Do not run power cords under rugs or carpets or place heavy objects on them.

• Damaged or deformed power cords are hazardous and should be replaced immediately by a qualified service technician.

LOCATION

• Do not use this product outdoors or in cars.

• Do not place this product in direct sunlight, or near heat sources.

• Keep this product away from strong magnetic objects.

VOLUME CONTROL

• Do not turn up the amplifier volume while listening to a portion with very low level input or no audio signal to avoid damage to your speakers during a peak level audio portion.

• Turn the amplifier volume control to minimum prior to connecting or disconnecting the transmitter or amplifier and prior to switching audio sources as this may cause loud clicks which can damage your speakers.

CARE

• Do not place any object containing water or other liquids on this product.

• Do not remove the cabinet. Touching parts inside the cabinet could result in electric shock and damage to the product.
