20. PRE OUT Terminal Strip
This terminal strip outputs the mixed audio signals of all sources (that are connected
to the amplifier’s inputs) and can be used to feed an external power amplifier, a signal
processor (e.g. an equalizer) or any other external appliance. The unbalanced signal is
affected by the individual input controls. Before using the PRE OUT you need to remove
the bridging-strip between this binding post and the MAIN IN terminal (21).

fier This opportunity provides a proper solution whenever shaping or improving
the audio signal is necessary (adjusting delay times, equalizing, eliminating the
Larsen-effect, etc.). The input is unbalanced, and is affected by the tone controls
and the master volume control.
22. AUX 1 and AUX 2 Inputs
These two RCA-type connectors let you connect the two channels of an external
high-level unbalanced signal source, such as an AM/FM tuner, a cassette deck, a CD
player etc. Use input sensitivity switch (27), suitable for difference appliances.
