[. . . ] LSR4328P, LSR4326P Studio Monitors Owner's Manual ii Important Safety Instructions 1. Install in accordance with manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus that produce heat. Do not defeat the safety purpose of the grounding type plug. [. . . ] For example, turning on the power to one speaker causes them all to power up; similarly, by changing the volume of one speaker, an equal volume change is made in all speakers. HiQnet networking also allows RMC calibration for all speakers to be accomplished with the push of a single button, with the supplied calibration microphone connected to a single speaker. It also makes it possible for all speakers in the system to be controlled using the supplied wireless remote control and/or LSR4300 Control Center Software. Up to eight LSR4328P or LSR4326P speakers can be interconnected in a single network. HiQnet enables coordinated RMC calibration so sound arriving at the mix position from all speakers is precisely balanced. Interconnect all speakers using the supplied CAT5 cable. Plug one end of the cable into either of the two HiQnet ports on one speaker and the other end into a HiQnet port on another speaker until all speakers are connected. (Speakers can be connected in any order). Place the two supplied Ethernet terminators on the first and last speakers in the chain. Finally, set each speaker's rear panel DIP switches according to its position in the system. For example, place the DIP switch labeled LEFT in the up (ON) position for the speaker reproducing the left channel, and place the DIP switch labeled RIGHT in the up (ON) position for the speaker reproducing the right channel. To set the DIP switch, gently push the white plastic nub of using a small flat blade screwdriver, a toothpick or other narrow object. Only one DIP switch should be in the up (ON) position. 21 Reference - AC Power Connections/Network Connections and DIP Switch Settings The illustrations below show typical network interconnections for both stereo and surround sound use. Networking interconnections and DIP switch settings for stereo use Networking interconnections and DIP switch settings for surround use At least one LSR4300 monitor in a networked system must have its LEFT DIP switch set to ON. When using only a single speaker, set the LEFT DIP switch to ON, regardless of the speaker's physical position in the room. If required, LSR4300 monitors can be used without being networked together (i. e. , without any CAT5 cable interconnections). In this case, the LEFT DIP switch in every speaker must be set to the ON position and all other DIP switches in every speaker must be in the OFF position. 22 Reference - Audio Connections Audio Connections The LSR4328P and LSR4326P speakers are equipped to accommodate a range of analog and digital signal input sources. You can connect two digital sources and one analog source to each speaker and switch between them using front panel controls, or the wireless remote control and/or LSR4300 Control Center software. Analog Connections Positive voltage to Pin 2 of the XLR connector or the tip of the ¼ jack will produce a forward motion in the speaker cone. See Appendix C in this manual for wiring diagrams. Analog signal sources must be connected to either the rear panel XLR or ¼ connector. Do not connect analog signal to both the XLR and ¼ inputs; use one or the other. The LSR4300 provides switchable input sensitivity between +4 dBu and -10 dBV, as determined by the two-position Input Sensitivity switch on the rear panel. When the sensitivity is set for +4 dBu, an input signal equal to +4 dBu will produce a system output level of 94 dB SPL at a distance of one meter. Likewise, a setting of ­10 dBV will cause an input level of ­10 dBV to attain the output acoustic level of 94 dB SPL at a distance of one meter.
