Loudspeaker Outputs

The speaker output jacks are suitable for connecting speaker cables with a maximum diameter of 2.5 mm2. The provided screwlock connectors can be screwed to the power amp to prevent inadvertent disconnection. Power amps offer low impedance outputs and / or floating outputs (ISOLATED OUTPUTS) with nominal voltages of 50V, 70V and 100V, depending on the amp model.

Caution: The symbol of a FLASH at the loudspeaker connectors indicates that these outputs may carry high voltages which, when getting in contact with, can cause serious harm. Establishing connections at these outputs is only permissible for persons who have been instructed on how to do so. Otherwise use prefabricated cables only.

PA2450L & PA4150L

Loudspeaker systems connected to channels A and B (or C and D) have to be connected according to the polarity indicated. Please, make sure to mind the minimal impedance of 4 ohms per channel.

For bridged operation, the load has to be connected according to the BRIDGED- label and the Mode switch needs to be set to “Bridged”. Please, make sure to keep in mind that in Bridged Mode the minimal impedance is 8 ohms and that the input audio signal has to be fed to channel A (or C).

PA1250T, PA2250T & PA2400T

Integrated audio output transformers convert the power amp’s nominal output voltage to 50V, 70V and 100V. The amplifier models PA2250T and PA2400T present all voltages simultaneously at the floating outputs so that the power amp channels can be used in any combination of possible output voltages. Mixed operation of low-impedance speaker systems and floating loudspeaker lines on a single power amp channel is possible as well.

The use of loudspeaker systems with 100V or 70V matching transformers to reduce the effects of cable loss is recommended when the distance between power amp and speaker systems exceeds 165 feet. In addition, this also facilitates distributing the output power among loudspeakers.

As many loudspeaker systems as possible can be connected, as long as the speaker network’s overall power consumption does not exceed the power amp’s rated output power while at the same time not falling below the nominal load impedance of the power amp outputs. Please refer to specifications in the appendix for individual values of the rated output power and nominal load impedance of power amp outputs.
