Connecting Your Subwoofer
-7-
Low Level (RCA) Input Connection
1. Locate the LINE IN RCA on the FF6.5 amplifier.
2. Connect the FF6.5 to the signal source, i.e. AV receiver. Even though there is no need to have both
RCAs to the signal source since the subwoofer is often operated in mono signal, we recommend
connecting the receiver to both RCA inputs in order to obtain higher signal level.
3. If needed, connect the LINE OUT RCA to another amplifier to drive satellite speakers (front or rear).
The LINE OUT RCA has high pass filtered signal at about 70Hz (5dB/Octave cut off).
