Analog Connections

For optimum performance, some attention to wiring details now can reduce system degradation later. The cabling recommendations given below follow standard wiring practice for differential inputs.

Balanced Sources

The best way to run your system is balanced, where both “HOT” (+) and “COLD” (-) signals are supplied from the source along with a GROUND/SHIELD. These are typically carried on 2 conductor shielded cables with XLR connectors on both ends.

Alternatively, connectors with Tip, Ring and Sleeve (T/R/S) jacks can be used. Whenever possible, the cable shield should not be connected to any signal pin, but left to perform a cable shielding function only. Note:

Under no circumstances should the safety ground wire be removed from the AC power connector.

When using balanced sources with the LSR4328P or LSR4326P, either the XLR or T/R/S input connector can be used, since the circuit is common to both. However, both inputs should not be used simultaneously.

For balanced signals, the HOT (+) signal from your source should be connected to the tip of the T/R/S connector or Pin 2 of the XLR input as shown in Diagram A. The “COLD” (-) signal should be connected to Pin 3 of the XLR or the “Ring” of the T/R/S connector. To avoid ground loops, connect the SHIELD at the source end but not at the LSR input.
