2.5 Boundary Compensation Device Models 201, 203, 205
Models 201, 203 and 205 incorporate a three position bass level control situated on the top of the terminal panel (see below). The ‘FLAT’
position is the factory setting which is suitable when the loudspeakers are positioned more than about 0.75m from the front wall, commonly
termed ‘free space’. The ‘CUT’ setting reduces the bass level by about 1.5 to 2dB for when the loudspeakers are positioned with their backs
right up against the wall. The ‘LIFT’ setting increases the bass level by about 1dB for free space positioning in rooms which absorb significant
amounts of the bass output. Experiment with the setting to determine which balance best suits your particular situation.
207 BCD adjustments are detailed on a seperate sheet.
