ALPHA Tube Preamplifiers

Series A-100

A 100LC Line + Cross:
Line Tube Preamplifier plus a two way electronic cross-over.

The preamplifier part of this unit is universal.
The electronic crossover part is especially designed to be used for bi-amplification of a system driving Analysis loudspeakers.

• Four inputs
• One conventional output
• Two additional outputs, to drive the separate amplifiers connected to your Analysis loudspeakers
    ° The first, is internally pre-adjusted to drive the high frequency (for the tweeter) amplifier
    ° The second, to drive the low frequency (for the woofer) amplifier

The electronic cross-over's output levels are able to be adjusted individually.
Thus, amplifiers of different input sensitivity may be used for the high and the low branches. (i.e. In bi-amplification it is sometimes desirable to use a tube amp for the highs and solid state for the lows).
Once the relative output levels are set, the central volume contron, masters all outputs.
