S120PII Studio Series
Dolby Digital or DTS (or Other Digital Surround Mode) Connection
Use this installation method for Dolby Digital, DTS or other digital surround processors: IMPORTANT: Make sure that the LFE toggle switch � on the subwoofer is in the �LFE� position. Use the Line Level input jacks ¶ for the LowFrequency Effects channel. Connect these jacks to the LFE output or subwoofer output on your receiver or amplifier. Note: If your receiver or amplifier has only one subwoofer output jack, then you may connect the subwoofer output on your receiver/preamplifier to either the left or right Line Level input ¶ on the subwoofer. It makes no difference which jack you choose. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier. Make sure that you have configured your surround sound processor for �Subwoofer On� or �LFE On.� The front left, front right, center and rear speakers should be set to �Small� or �Large� depending on their size and frequency response. Consult your receiver�s or processor�s owner�s manual.

BassQ� Jacks
The jacks marked �BassQ� § are for use with the JBL BassQ bass equalization module that will be released in the near future. The BassQ will enable you to optimize your system�s bass response by equalizing the output of multiple subwoofers to best match your listening environment. DO NOT connect these jacks to any other device. Do not use the BassQ jacks § without having first read the BassQ owner�s manual.
