Palmer Passiver 2Kanal Line Summierer

Sometimes it is necessary to route two stereo signals to a single device, for example if two mixing consoles are to drive a common stereo power amplifier. In practice, however, this often leads to unwanted hum loops. This is where Palmer offers a reliable solution with the passive summing amplifier Main. It combines two stereo input signals via a resistor matrix, whereby the input pair A is galvanically isolated by a transformer to effectively prevent hum loops.

The Palmer main works completely passively, which makes it particularly low-noise and sound-neutral. Thanks to its generously dimensioned transformers, it can also handle high levels of up to +20 dBu without distortion. The transformers also allow the input pair A to be connected unbalanced, while the output signal remains balanced.

Thanks to its passive mode of operation, which does not require an external power supply, the Palmer main is characterized by its particular reliability. The robust aluminium/steel housing and the XLR connections are also ideally suited for demanding stage use. The Palmer main merge box offers a simple and uncompromising solution for typical sound reinforcement problems, with outstanding sound quality.
