15. "PRE OUT" terminal
This terminal output the mixed audio signals of all sources that are connected to the amplifier
Inputs and can be utilized to feed an external power amplifier, a signal processor (e.g.a equalizer)
or any other external appliance. The unbalanced signal is affected by the individual input
controls. Before using the PRE OUT you have to remove the bridging-strip between this
binding post and the "MAIN IN" terminal(16).

16. "MAIN IN" terminal
After removing bridging-strip between the "PRE OUT" and the "MAIN IN" terminals you can
include an external signal processor (e.g an equalizer) in the audio-chain between the
pre-amplifier and the power output stage of the power amplifier. This opportunity provides
a proper solution whenever shaping or improving the audio signal is necessary (adjust delay
times, equalizing, eliminating the larseneffect, ect.) The input is unbalance, which affected
by the tone control and the master volume control.
17. "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(20). Suitable for different appliances.
