23. Line Out A/B
The LINE OUT connector is useful for providing unbalanced line level signal to another amplifier or
other external devices. Prior to using this feature one must understand where the internal signal pick
up point is so you can decide if it is correct for your application. We suggest you refer to the block
diagram of the AA120/AA240 to have a complete understanding of the signal flow.
Note the following conditions for LINE OUT
A. Pre Low Cut Filter
B. Post Tone Controls (meaning the settings for the Bass and Treble controls affect this signals
output). Note: Refer to “Low Cut Filter Switch for complete understanding of the LCF feature.
C. Post Amp In (meaning any signal that is inserted into the Pre AMP In jack will be present at
the Line Out).
24. Tape Out A/B
Line level mono signals are available at this jack for connection to recording devices. The signal
available here is PRE tone control and low cut filter and comes from the internal mix bus.
25. Pre Out
The PRE OUT connector has Post tone control signals available to drive another power amp or
external audio devices. Use in conjunction with the AMP IN connector, an effects loop can be created
by connecting the PRE OUT jack to a device such as an equalizer then back out to the AMP IN
connector. See the connection diagram in the setup section of this manual.
26. Pwr In
The AMP IN connector is useful for converting the AA120/AA240 into a slave amp. When a line level
signal is connected to this input, the internal connection between the preamp and internal power amp
is broken. The AA120/AA240 is now just a power amplifier, amplifying audio signals applied to this
connector.
