Harman Kardon 150 Owners Manual - Page 9

When in this position the separation between LEFT and RIGHT will be partially reduced from that obtained in the normal SQ MATRIX position and the separation between FRONT and BACK will be slightly increased. When reproducing full orchestral material, the mode selector should be in the SQ MATRIX position. When reproducing individual instruments or soloists the mode selector switch should be in the SQ MATRIX BLEND position. LEFT B RIGHT FRONT SPEAKFR BALANCING LF (BACK SPEAKERS OFF) RF ENHANCED STEREO (STEREO TO QUAD) This position should be used to enhance (convert) any stereo source into spatially expanded sound. When playing any stereo source, if your 150+ has been installed in QUAD with four or eight speakers, the sound will emerge from each speaker filling the room with sound that is almost as exciting as authentic 4-CH. It may also be used to spatially enhance a monophonic source. In this position the Ig 4 mode indicator lights will be illuminated, denoting stereo to 4-CH operation. QUAD DISCRETE In order to utilize this position you MUST have a four channel source connected to the system. In this position 4 4 mode indicator lights will be illuminated denoting 4-CH to 4-CH operation.

It is a four section control which simultaneously adjusts all channels, and its close tracking specifications insure that the relative volume level of each channel will be identical. TUNING The tuning knob, located on the right side of the receiver is used to select the desired station when your FUNCTION switch is in the FM, STEREO FM, or AM position. SOUND FIELD BALANCE Your 150+ incorporates a unique four channel continuously variable balance control. The nature of stereo or 4-CH reproduction is such that it requires identical channels to attain the highest degree of faithfulness and spatial distribution. Any variation in the efficiency of any channel as compared to the others will disturb this relationship. Since there may be slight differences between program material, room acoustics, etc., your receiver includes a control to balance all channels. Sufficient range is covered by this control to permit rebalancing of the overall system even in cases where major unbalance exists. This control may be set anywhere within its range to attain system balance. It does not necessarily have to be set in the exact center position. When the BALANCE control is properly set, the apparent sound source will lie in a broad area between all speakers. SELECTING MONOPHONIC OR FM STEREO BROADCAST Under normal use for all FM broadcasts the function selector switch should be placed in the STEREO FM position. Your receiver is equipped with a stereo sensing circuit which will automatically determine whether your unit is receiving monophonic or stereophonic broadcasts, and then automatically adjust the mode of operation. If the station is transmitting stereo, your receiver will automatically switch on the multiplex section and you will hear the broadcast in full stereo. Should the station conclude broadcasting in stereo, your receiver will automatically switch back to monophonic reception. Should you receive a weak stereo signal whose quality has been degraded by noise or poor signal conditions, and you wish to listen to this stereo broadcast monophonically, place the function selector switch in the FM position. 8
