Lsr6328P Systems With Lsr6312Sp Subwoofer - JBL Room Mode Correction User Manual

II. LSR6328P Systems With LSR6312SP Subwoofer
First, make sure that you have completed steps for a stereo LSR6328P system. Signal for
the left and right LSR6328P speakers should be fed through the main LSR6312SP unit and
the calibration of the left and right LSR6328P units must have been done with the
LSR6312SP powered off or in Bypass mode (See LSR6300 owner's manual). Now, to cali-
brate the RMC system of the LSR6312SP, power up the unit and make sure the Bypass is
not active. (See Figure 12) Ensure the RMC system on the LSR6328P units are active.

After the system is connected and levels have been calibrated according to the proce-
dures that follow, the contribution of the subwoofer will match that of the main channel
loudspeaker (Figure 13), resulting in smooth response over the crossover region between
the two.
