    ECHNICAL ESIGN trans•nova (TRANSconductance NOdal Voltage Amplifier) The trans• nova (TRANS conductance NOdal Voltage Amplifier) is a patented circuit (U.S. Patent 4,467,288) that allows the audio signal to pass through the amplifier at low voltage . Each amplifier channel utilizes its own “fully floating” power supply and is configured to increase power gain.
  • Page 6 The DSM (Discrete Surface Mount) manufacturing process combines the advantages of both discrete components and integrated circuitry. Rockford Fosgate is the only American amplifier manufacturer to have invested millions into this process. DSM components differ from conventional discrete components in different ways. They are more compact, more rugged, and they efficiently dissipate generated heat.
  • Page 7 (Metal Oxide Semiconductor Field Effect Transistor) Rockford Fosgate is one of the few manufacturers in any of the sound communities to utilize MOSFET devices in both the power supply and the output stages . MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer several important inherent advantages over the 30 year old technology of bi-polar design.

    Balanced Line Input– This input will allow the Balanced Line Transmitter (BLT) or any balanced Rockford Fosgate source unit/signal processor to be used in conjunction with the amplifier to provide better noise rejection.
  • Page 9 Bass EQ Control – The Bass EQ allows a narrow band adjustment of up to +18dB centered at 45Hz. The bass boost can be bypassed by turning the control to its minimum or counterclockwise position. E-Z Bridge Switch / 0 -180 Phase Switch – This dual purpose switch enables you to E-Z bridge the amplifier or invert the signal phase of the right channel.

    I R I N G Y S T E M CAUTION: Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or harnesses. The power wires carry substantial current and could induce noise into the audio system. 1.

    11. After the final inspection is complete, install the power fuse and enjoy listening. During the initial listening period, you may need to “fine tune” any phasing and level settings within your particular vehicle. To aid in this procedure, play a track with high musical content and cruise around your neighborhood.

    S I N G T H E The crossover functions are controlled through the use of an XCard and can be set for high-pass, low-pass or full range operation. The XCard shipped with your amplifier is set for Full Range. Each crossover card has two faces: one face operates Full Range, the other has arrows to indicate the edge for selecting HP (high-pass) or LP (low-pass) operation.

Unlike standard RCA cables that use two wires to carry the audio signal and ground, balanced lines use three. In a balanced line, the output signal and its inverted replica travel down a pair of wires where the ground connects via the shield.

  • Page 29 III. MOVE THE DECK. If you're at this step, it's time to turn your system into an “amplified deck” by temporarily relocating the deck right ON TOP of the clean amplifier. Then using very, very short signal cables, connect the output of the deck into the input of the amp and test for noise.
  • Page 30: Dynamic Power Measurements

    The IHF-202 standard is a dynamic power measurement and was developed as a means of measuring power in a manner that best represents the Real World operation of an amplifier. Many manufacturers, including Rockford Fosgate, at times will measure amplifier power into a fixed resistor (4 ohm, 2 ohm). While this method is useful in some types of evaluation and testing, it is not representative of an amplifier that is connected to a speaker and playing music.
