Heavy duty gold plated RCA connectors for input and output. Outputs are always in phase. Toroidal power transformer. The XM26 uses 4 12AX7 tubes in each of the two channels. It has a solid state regulated power supply for both the plate voltage and the filament voltage.
Power is provided with a heavy duty toroidal power transformer.
The crossover frequency of XM26 Electronic Crossover Network can easily be set by replacing a frequency module. A total of four frequency modules set the crossover frequency for left and right, low and high pass filters. Each frequency module has the capacitors and resistors that set the crossover frequency and slope for that channel. The XM26 front panel has 4 calibrated level controls, one for each low pass and high pass, for left and right channel. A sum switch allows the low pass channel to be summed.
