– 1 – The F A10.0, F A12.0, and F A15.0 monitors utilize a specially designed amplifier featuring our innova- tive T rans • ana cir cuitry . This topology , with its unique input-to-output configuration (derived from our patented T rans • nova cir cuit), employs power gain in the MOSFET output stage that result in superior sound quality .
– 2 – MEHSA (Maximum Efficiency HeatSink Application) MEHSA is a proprietary process that yields up to 5 times better heat transfer than traditional FET mounting techniques using the exact same components.
– 3 – Subsonic Filter The Point Zero series uses a Subsonic Filter to prevent the woofer from reproducing inaudible frequen- cies. Subsonic frequencies, (known as infrasonic frequencies), are signals below the normal human hearing range.

Home Theater Installations Home Theater installations are typically medium sized living rooms or game rooms that have large, flat walls. Acoustics in this type of installation can have a big effect on the SPL (Sound Pressure Level) and f3 (low frequency cut-off) of the subwoofer because the walls are very reflective.

– 8 – * This graph was generated by setting the variable crossover to 40Hz 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 120Hz & 140Hz. Auto T urn-on / Sleep Mode The Fosgate Audionics subwoofers automatically turn on when they sense an input signal.
– 9 – Phase Control The Phase Control switches allow the Fosgate Audionics subwoofer to be acoustically aligned with other speakers in your system. 0 ˚ , -90 ˚ , -180 ˚ , or -270 ˚ degrees of phase shift at 80Hz can be selected using DIP switches 2, 3, and 4.
– 10 – AC Line The F A10.0/F A12.0/F A15.0 operate from a 1 15 V AC/60Hz power line. The F A10.0CE/F A12.0CE/F A15.0CE operate from a 230 V AC 50/60Hz power line. Connection is made by a 16 gauge, IEC T ype 320, grounded line cord. For safety considerations only a properly grounded (earthed) receptacle should be used.
– 11 – Rockford Corporation (Fosgate Audionics Division) offers a limited warranty on Fosgate Audionics prod- ucts on the following terms: • Length of W arranty 1 year on Subwoofer Monitors • What is Covered This warranty applies only to products sold to the original owner and is non-transferable.
– 12 – The lightning flash with arrowhead symbol within an equilateral tri- angle is intended to alert the user to the presence of uninsulated “ dan- gerous voltage ” within the product ’ s enclosure, that may be of suffi- cient magnitude to constitute a risk of electric shock to persons.
