Speaker setup and testing
The relative volume of the speakers must be adjusted for optimal surround sound. You should be at your usual listening position when adjusting the speaker volume. See “Receiver menu” on how to unit up the receiver for the used speakers. Ideally, the volume in the listening position should be the same from all speakers.
1 | Press POWER / STANDBY to switch on the receiver. |
2 | Press TEST TONE on the remote control. |
Positioning the speakers
General hints for positioning
Avoid positioning the speakers in a corner or on the floor as this will boost the bass tones too much. Placing the speakers behind curtains, furniture, etc. will reduce the treble response. The listener should always be able to ”see” the speakers.
Each room has different acoustic characteristics and the positioning possibilities often are limited. You can find the best position for your speakers by referring to the picture above.
As a minimum we recommend 5 speakers (2 front, a center, 2 surround) for good surround sound. It is possible to reproduce some kind of surround sound with fewer speakers. This is done by redirecting the signals which are foreseen for the missing speakers to the existing ones. See “Menus” on how to set up the receiver correctly for the number and size of the speakers used.
Positioning the front speakers
The front speakers should be placed to the right and left in front of the listening position like usual stereo speakers.
Positioning the center speaker
The center speaker should be placed in the center between the two front speakers, e. g. underneath or on top of the TV. The best height for the center speaker is the height of the listener’s ears (while seated).
Positioning the surround speakers
The surround speakers should face each other and be in line with, or slightly behind the listener.
Positioning the subwoofer
A subwoofer can be used to enhance the bass performance of your system dramatically. The subwoofer can be positioned anywhere in the room, because it is not possible to locate the source of deep tones. Nevertheless, you should not place the subwoofer in the middle of a room, since the bass could be severely weakened. Do not place any object on the subwoofer.

3 | Press +/- REAR on the remote control to |
| increase/decrease the volume of the actual speaker. The |
| best result is achieved when all speakers have equal |
| volume in the listening position. |
4 | Press TEST TONE on the remote control. |

Note: If you are not completely satisfied with the volume settings, we recommend making minor adjustments to them during surround sound playback.
Power handling
If the receiver is used at very high power it can produce distortions which may damage your speakers seriously. If distortions occur, reduce the volume and the tone controls to a level where the sound is acceptable again.
To avoid overheating of the unit a safety circuit has been built in. Therefore your set may disconnect under extreme conditions. If this happens, switch the unit off and let it cool down before reusing it. After having let the set cool down switch the set on again and select the desired source by turning SOURCE SELECT.
Headphones
Connecting headphones to PHONES will switch off the speakers. The receiver switches to STEREO and surround sound will be reduced to a stereo signal which is reproducible by standard headphones.
Disconnecting the headphones switches on the speakers again. If you wish to enjoy surround sound again, switch the receiver back to surround sound.
Maintenance
Clean the receiver with a soft, slightly dampened,
Do not expose the receiver to humidity, rain, sand or excessive heat (caused by heating equipment or direct sunlight).
