Audio Connections

The LSR2300 Series Speakers are equipped with balanced XLR and 1/4" TRS connectors and unbalanced RCA connectors for connection of professional computer audio interfaces, mixing consoles and audio production equipment as well as unbalanced consumer audio products including personal music players, consumer audio receivers and audio visual equipment.

Connect professional equipment with balanced outputs to the XLR or ¼" TRS input of the speaker using balanced signal cables. (More information is available www.jblpro.com/lsr click on support.)

Connect consumer equipment with unbalanced outputs to the RCA input of the speaker.

The volume control on the rear of the speaker should be set to achieve the comfortable listening level when the signal source is playing at it’s loudest volume. Positive voltage to Pin 2 of the XLR connector, the tip of the 1/4" TRS jack, and the RCA jack will produce a forward motion in the low frequency cone.

Power Connections

The LSR2300 Models include a rear panel voltage selector switch that is set at the factory for the appropriate voltage. Before connecting the power cable it is a good idea to check the position of this switch to confirm the voltage switch is correctly set for the country of use. The power connector on the speaker includes a user- replicable protective fuse. The ground terminal of the IEC plug is required by wiring codes and regulations and must always be connected to the electrical installation safety ground. The LSR2300-Series units have carefully designed internal grounding and balanced inputs and outputs to reduce the possibility of ground loops that produce hum. If hum occurs, see Appendix A for suggested audio signal wiring, system grounding hints and other preventive measures.

Making Sound

After connections are made, reduce the output level of the audio source (mixing console, computer recording system, or preamp) to minimum. Turn on the powered speakers. When the Blue LED on the front of each speaker illuminates, the speakers are ready to reproduce audio signals. Power up all audio equipment. Slowly advance the volume control of connected audio equipment to achieve a suitable listening level, and enjoy.
