Toroidal power transformer.
The XM26 Electronic Crossover Network is a
fourth- order constant-voltage crossover design that provides
both low-pass and high-pass outputs. The slope of each output is
normally 24 dB/octave and, because of the fourth-order design,
the high-pass and low-pass outputs of the crossover are always
in phase with each other on 24dB/oct filter selection. Other
slopes of 6dB/oct, 12dB/oct or 18dB/oct are available.
The XM26 uses 12AX7/ECC83 tubes in each of the two channels. It
has a solid state regulated power supply for 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. Normal slope is 24 dB/oct, 4th order,
constant voltage (Linkwitz-Riley), but modules for first, second
and third order slopes are also available.
The XM26 front panel has 4 calibrated level controls using
stepped attenuators, one for each low pass and high pass, for
left and right channel. A sum switch allows the low pass channel
to be summed. This is useful when using the XM26 with a common
subwoofer.
Available options include 24 position stepped attenuators
instead of the standard 12 position attenuators for level
control. The 24 position stepped attenuators are calibrated in
0.5 dB steps and allow very fine setting of the levels for each
output.
The XM26 is also available as 1-way instead of 2-way. The 1-way
can be used as low-pass only to drive subwoofers or as high-pass
only.
