    Explanation
    The deliverable power to a single amplifier channel is defined by the current and voltage. Current refers to the flow of electric charge in the circuit, while voltage is the potential difference that drives the current. These two factors determine the amount of power that can be delivered to the amplifier channel.

    Rate this question:

  • 6. 

    What mode combines two channels to provide more power to higher impedance loudspeakers?

    • A.

      Bridge

    • B.

      Parallel

    • C.

      Power Factor Correction

    • D.

      Intrinsic Correction

    Correct Answer
    A. Bridge
    Explanation
    Bridge mode combines two channels to provide more power to higher impedance loudspeakers. In this mode, the two channels are connected in parallel, with one channel's output inverted and then combined with the other channel's output. This results in an increased voltage and power output, allowing for better performance with speakers that have higher impedance.

    Rate this question:

  • 7. 

    Which loudspeakers benefit most from a Bridge-Parallel mode?

    • A.

      Loudspeakers with impedance in the 4 – 8 ohm region

    • B.

      Loudspeakers with impedance more than 8 ohms

    • C.

      Loudspeakers with impedance less than 4 ohms

    Correct Answer
    A. Loudspeakers with impedance in the 4 – 8 ohm region
    Explanation
    Loudspeakers with impedance in the 4 - 8 ohm region benefit most from a Bridge-Parallel mode because this mode allows for combining the power of two channels to drive a single loudspeaker. In this mode, the impedance of the loudspeaker is effectively halved, which means that loudspeakers with higher impedance (more than 8 ohms) may not be able to take full advantage of the increased power. On the other hand, loudspeakers with lower impedance (less than 4 ohms) may be at risk of overloading the amplifier. Therefore, loudspeakers with impedance in the 4 - 8 ohm region are the most suitable for this mode.

    Rate this question:

  • 8. 

    What mode combines two channels to provide more power to lower impedance loudspeakers?

    • A.

      Bridge

    • B.

      Parallel

    • C.

      Power Factor Correction

    • D.

      Intrinsic Correction

    Correct Answer
    B. Parallel
    Explanation
    Parallel mode combines two channels to provide more power to lower impedance loudspeakers. In this mode, the positive terminals of both channels are connected together, as well as the negative terminals. This results in the total impedance being halved, allowing for more power to be delivered to the speakers. By combining the power of two channels, parallel mode is able to drive lower impedance speakers more efficiently and effectively.

    Why is the PLD/CXD built “upside-down”?

    • A.

      To keep small particles from ending up on the circuit boards

    • B.

      To make the amplifier harder to duplicate

    • C.

      Gravity is critical to the amplifier’s power capacitors

    Correct Answer
    A. To keep small particles from ending up on the circuit boards
    Explanation
    The PLD/CXD is built "upside-down" to prevent small particles from ending up on the circuit boards. By placing the boards upside-down, any particles that may fall during the manufacturing process will fall away from the sensitive components, reducing the risk of short circuits or other damage. This design helps to ensure the reliability and performance of the amplifier by minimizing the chance of contamination from particles.

    Rate this question:

  • 14. 

    Why do channels A and C share a heat sink?

    • A.

      Since channel A is most commonly paired with channel B, this spreads out the thermal load when channel A and B are in use.

    • B.

      They share one circular heat sink with channels B and D as well.

    • C.

      Since channel A is most commonly paired with channel C, this allows one heat sink to handle both of their thermal loads, letting the other heat sink cool down.

    Correct Answer
    A. Since channel A is most commonly paired with channel B, this spreads out the thermal load when channel A and B are in use.
    Explanation
    Channels A and C share a heat sink because channel A is most commonly paired with channel B. This arrangement helps to distribute the thermal load evenly when both channel A and B are in use. By sharing a heat sink, the thermal load of both channels can be handled effectively, allowing the other heat sink to cool down. Additionally, channels B and D also share the same circular heat sink, further optimizing the cooling system.
