AA60 MIXER AMPLIFIER
OWNER’S MANUAL
18. Pre Out
The PRE OUT connector allows Post tone control and low cut filter (when engaged) functions to be available
to drive another power amp or external audio device(s). Used 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 Example 3 in the Setup section of this manual.
19. Amp In
The AMP IN connector is useful for converting the AA60 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.
Audio signals applied to this connector are post tone control and input level controls.
20. Breaker
The circuit breaker is designed to trip and shut down the AA60 "Unswitched Outlet" upon an over current
condition. After correcting the cause of the breaker tripping, reset the breaker by pushing in on the tab.
21. Unswitched Outlet
The unswitched outlet provides power for other devices (Atlas Sound rack work light, etc.) and is live
whenever the power cord is plugged into a live outlet. Total power draw must not exceed 500 W.
22. Output Terminal Strip
For loudspeaker connections, connect as follows or proceed to the setup section for typical wiring schemes.
COM - Speaker common or negative connection
4Ω - Connect to direct coupled loudspeakers
25V - Connect to transformer coupled, 25V loudspeakers with a total load impedance of no less than 10.4Ω
70V - Connect to transformer coupled, 70.7V loudspeakers with a total load impedance of no less than 83.3Ω.
