  • Make sure the amplifier is powered down.
  • Place the MODE switch (located on the back panel) in the Parallel-Mono position.
  • The input connector should be inserted into channel one (leave the channel two input empty).
  • Place a small diameter wire (14 gage {1.63 mm}) between the two red output binding posts.
  • Connect the speaker leads across the red and black binding posts.
  • Channel one level control should be used to control output level.

How to determine the best input sensitivity setting?

The input setting has to be matched with the output level of whatever is before the amp in the audio chain. For instance, amplifiers with 0.775V position corresponds to a 0 dBu level.

Conclusion

Both the Crown XLI and Crown XLS series offer great audio amps with power and durability. However, the Crown XLS are newer, class d, and offer electronic crossover, whereas the xli are Class AB. There isn’t much significant difference in the performance of the amplifiers but we can surely say that the Crown XLS offers better performance with more features that are useful in every way.
