The SymbiLink

 Z250C4-SL

Thank you for purchasing the Z250C4-SL.

The Z250C4-SL is a four channel amplifier that is conservatively rated at
30 watts x 4 into four ohms, 60 watts x 4 into two ohms and 100 watts x
4 into one ohm loads.

The Z250C4-SL features SymbiLink

 balanced inputs.  These

professional style connections eliminate induced distortion and noise for
the ultimate in sonic purity.  The SymbiLink

 system also allows for

simple connections to other SymbiLink

 components, greatly simplifying

the installation process.

The power supply in the Z250C4-SL is a new design that dramatically
increases the available power and efficiency.  New Gate Drive Boost
circuitry greatly improves the MOSFET switching performance and
allows cooler operation.  Low distortion, very high stereo separation and
smooth, fast transient response are all characteristics of this amplifier.
