5NF-01A (Powered Near Field Studio Monitor)Block diagramControl positionsEnclosure positioningTo optimally enjoy NF-01A's accurately time-aligned performance, each enclosure must be positioned sothat the 2 drivers will be aligned on a vertical line. The human ear's sensitivity in the right-left directionmakes horizontal positioning of enclosures undesirable.Vertical positioning is also recommendable so that heat generated by the amplifiers can be more effectivelydissipated.* Power output adjustmentTurning clockwise using a Philips screwdriver increases volume.* Tweeter level adjustmentAn adjustment of a range of +/- 3dB ispossible. Turning counterclockwise fromthe center position (0dB) decreases thetweeter output level, and turning clockwiseincreases the tweeter level.This control is factory-set at the "0dB" po-sition.* Correction to low frequency (55Hz) characteristicsThis LO FREQ switch permits correc-tion of the low frequency (55Hz) re-sponse by +/- 2dB.This control is factory-set the "0" po-sition. By setting the switch at the"+2dB" position, the 55Hz response will be enhanced.Setting to the "-2dB", the response will be attenuated by2dB.<Vertical positioning><Horizontal positioning>INPUT (UNBAL)-10dBVINPUT (BAL)+4dBu1: GND2: HOT3: COLD+2dB-2dB0dBVOLTWEETERLEVELHF POWERLF POWERTWEETERWOOFER8070905060110100(dB)20Hz50100 200 5001k 2k5k 10k20k40kWf: +2dBWf: -2dBTw: +3dBTw: -3dB
