7. LEvEL bALANCE AND POLARITy
When using the FB-150 series in conjunction with full range speakers (such as TOA's HX-7 Series Speaker System), adjust
the level balance and polarity for each speaker independently depending on the installation site.
[Level balance adjustment]
Increase or decrease the level of the subwoofer (or full range speaker) as appropriate to the number of units and installation
conditions.
[Polarity adjustment]
• If the subwoofer and full range speakers are in phase in their crossover band, then acoustic energy is added; however,
acoustic energy is subtracted if the two are in reversed phase. Since the phase characteristics of both the subwoofer and
full range speaker change continuously depending on the frequency, it may not be ideal to follow the subwoofer's polarity
instructions when connecting it.
• Compare the degree to which acoustic energy increases by switching the polarity of the connection at the subwoofer
(from positive to negative and from negative to positive). Choose the way of connection that results in the greatest
increase in acoustic energy. To match the polarity correctly, make actual measurements of acoustic energy using a real
time spectrum analyzer.

6. EQUALIZING by DIGITAL SIGNAL PROCESSOR
When using the FB-150 Series Subwoofer System in combination with the TOA HX-7 Series Speaker System, it is
recommended that the TOA Digital Signal Processor (DSP) be used to set the recommended parameters.
For setting, refer to the HX-7 Series instruction manual.
