The main output connectors of the LX741 are 5-Way (BLK/RED) binding posts for standard connection to the loudspeaker or other load device. The XLR female input connector provides for typical connection to balanced or unbalanced signal sources.

For most applications this will be the typical configuration, eliminating both ground loops and common mode noise between any source and the LX741 power amplifier.

However, if true unbalanced connection is desired, two internal jumpers are also provided to force the amplifier common to chassis ground, and to connect Pin-3 to the COM/GND as well.

Two BNC connectors are provided for the Voltage and Current monitor outputs. Each of these outputs provide the means to obtain both voltage and current signal data associated with the load. Since the load is driven under true voltage source drive conditions, acoustic SPL data on the driver can also be obtained at the same time.

This enables true and accurate impedance data to be obtained as driven by a low impedance voltage source. This also allows distortion in the current signal of the load to be easily measured, or acoustic distortion at the same time.

Four color coded LED indicators are provided to indicate signal condition and gain. They are: MUTE, 0.0dB, +10.0dB, and +20.0dB. These indicators reflect software program control settings and/or configuration changes.
