11. Power Socket
  Connect the power cord to 240VAC only. Serious 
damage may result if accidentally connected to 
other line voltages.
12. 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.
13. Pwr In
  The AMP IN connector is useful for converting 
Mixer amp 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. Mixer amp is now just a 
power amplifier, amplifying audio signals applied 
to this.
14. 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.
15. Line Out A/B
  The LINE OUT connector is useful for providing 
unbalanced line level signals 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 
Mixer amp 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).
16. Input 5/6
  INPUT 5/6 consists of a pair of stereo line level 
inputs. Connect unbalanced audio outputs, 
such as CD player/MP3 player to input 6 only. 
Input 5 cannot be muted as this may be used 
for priority t devices such as an Alert/Avac 
controller.
