Welcome! Thank you for purchasing the Sony Active Super Woofer. Before operating this woofer, please read this manual thoroughly and retain it for future reference.
Getting Started Unpacking Installation Check that you received the following items: • Audio connecting cord (1) • Speaker cord (2) Since the human ear cannot detect the direction and position where the bass sound being reproduced by a woofer (below 150 Hz) comes from, you can install the woofer wherever you like in your room. To obtain a better bass reproduction, we recommend you to install the woofer on a solid floor where the resonance is unlikely to occur.
Getting Started Hooking Up the System Overview Use the LINE IN jack or the SPEAKER IN terminals of the woofer when you connect the amplifier. • If your amplifier has one of the following types of output jacks, connect the LINE IN jack and the amplifier's jack using the supplied audio connecting cord.
Getting Started Connecting to an amplifier with a single set of speaker terminals Connecting to an amplifier with double(A+B) sets of speaker terminals If your amplifier is equipped with a single set of speaker terminals, connect the woofer to the amplifier, and then connect the front speakers to the woofer. If your amplifier has double(A+B) sets of speaker terminals, connect both the woofer and the front speakers to the amplifier.
Getting Started Connecting to an amplifier with a special jack for a super woofer If your amplifier has a special jack for a super woofer (like a MONO OUT jack, MIX OUT jack, SUB WOOFER jack or SUPER WOOFER jack), connect the LINE IN jack of the woofer to one of those jacks.
Basic Operations Listening to the Sound POWER MIN U POWER Note Never set the amplifier’s tone control (BASS, TREBLE, etc.) or the equalizer output to a high level or input sinewaves of 20 Hz to 50 Hz recorded on a commerciallyavailable test disc or special sound (bass sound of electronic musical instrument, pop noise of analog disc turntable, sound with abnormally enhanced bass, etc.) in a high level to this unit. These actions may cause damage to the speakers.
Basic Operations Adjusting the Sound You can adjust the sound of the woofer to suit the sound of your front speakers. Reinforcing the bass sound gives you a greater sense of atmosphere.
