CAUTION graphics are used to highlight certain topics that require extra precaution. Overview A single AE Techron amplifier can provide continuous output current or voltage only up to a certain level. If you need increased output above those levels, you can combine multiple amplifiers into a system that can provide increased voltage or current. -

Use only 2100 or 7000-Series Amplifiers of the same Model Number Use only AE Techron 2100 or 7000-Series amplifiers of the same model to construct these multiple amplifier systems. You CANNOT combine different models of 2100 or 7000-Series amplifiers in the same system, such as combining 7224 amplifiers with 7548 amplifiers. -

AE TECHRON MULTI-AMP CONFIGURATION GUIDE Remove Slave Labels (optional) We recommended removing any “Slave” amplifier labels to avoid later confusion or errors. Reconfigure SIM-BNC-OPTOC Cards. Refer to Figure E-5 for SIM-BNC-OPTOC factory-default settings. Note that for normal stand-alone operation, jumpers J6 and J7 (Master/Slave) should be returned to the factory defaults. Stand-alone amplifiers can operate with jumpers J4 (Balanced/Unbalanced) and J5 (Ground Lifted/Chassis Ground) set to either selection, depending on the user’s preference.
