¡ Bias Battery: The bias batterysupplies constant DC bias to thecrossover capacitors, eliminatingcrossover distortion at zero electricpotential. Replace the test batterysupplied with your system with a9-volt, 006P rectangular battery assoon as possible. Thereafter,although the speaker will functionwithout the battery, JBL recommendsthat you replace the battery everytwo years for best performance.Access the battery by unscrewing thecover. Make sure to observe properpolarity when installing the replace-ment battery.™ Network Mode Switch:This switch should be left in the“Normal/Bi-Wire” position unless youare connecting the speaker in a bi-amp configuration using two poweramplifiers and an external electroniccrossover. Access the switch byunscrewing the battery cover. Theswitch may be adjusted using a flat-head screwdriver.£ HF Trim Switch: This switchallows you to adjust the output of thehigh-frequency transducers to com-pensate for the acoustics of yourroom. The +1dB position increasesthe output, the 0dB position is a flat-level position, and the –1dB positiondecreases the output. Each positionwill affect the tonal balance over awide frequency spectrum. Experimentby placing the switch in each positionwhile listening to familiar programmaterial and choose the position thatsuits your room acoustics and listen-ing preferences. You may find thatafter a few months, once the trans-ducers have settled in, that anotheradjustment is necessary. This isnormal. Access the switch byunscrewing the battery cover. Theswitch may be adjusted using aflathead screwdriver.¢ Mid/High-Frequency InputTerminals: For bi-wire or bi-ampconfigurations, connect the speakerwires for the mid- and high-frequencyranges to these terminals.∞ Shorting Bars: Leave the short-ing bars in place only if you are usingthe passive single-wire connectionoption described on page 15.Otherwise, remove the bars to pre-vent possible damage to the speakersor your electronics.§ Low-Frequency InputTerminals: For bi-wire or bi-ampconfigurations, connect the speakerwires for the low-frequency range tothese terminals.14CONTROLS AND CONNECTIONS(–)(–)(+)(+)High FrequencyLow FrequencyBI-AMPHIGH FREQUENCY TRIM+1dB0dB–1dBNORMAL/BI-WIRE¡ ™ £¢∞§Figure 9.
