– 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 . T[...]

– 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. A multi-layer insulated metal substrate operating with minimal thermal resistance spreads heat both downward and outward to quickly dissipat[...]

– 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. The subsonic filter reduces the energy of these frequencies and restrains the woofer from operating outside [...]

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. The only ele- ments in these in[...]

Auto T urn-on / Sleep Mode The Fosgate Audionics subwoofers automatically turn on when they sense an input signal. When the signal being fed to the subwoofer is turned off, the subwoofer ’ s amplifier will turn of[...]

– 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. For 0 ˚ degrees of phase shift, leave all three switches in the OFF (up) position[...]

– 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. If a grounded circuit is n[...]
