The Digital Effects
The PA6FX/PA8FX features sixteen built-in digital effects. Rotate the DSP
control (#12) to select the desired effect. Each channel’s DSP/Eff control
(#7) adjusts the amount of effect applied to its channel. The main DSP
Ret control (#13) determines the overall amount of internal effects
applied to the output signal.

15. TAPE IN LEVEL:
Use this control to adjust the level of the signal from the
tape In jacks (#21).
16. MAIN:
Use this control to adjust the main mixed signal level sent to the
mixer’s internal power amplifier. To avoid overdriving the amplifier, this con-
trol should be set around 6 or 7 to allow sufficient headroom for peaks in the
program material.
17. MONITOR:
Use this control to adjust the level of the signal from each
channel’s Mon control (#6) sent to the Monitor Out jack (#18).
18. MONITOR OUT:
Use this jack to send the monitor signal to your moni-
tor amp and speakers.
19. EFFECTS SEND:
Use this jack to send the signal from the DSP/Eff bus
(from each channel’s DSP/Eff control, #7) to the input of an external effects
device. This signal is post-channel level, post-channel eq, pre-master.
20. EFFECTS RETURN:
Use this jack to return the output signal of an external
effects device back into the mixer for processing.
21. TAPE IN/TAPE OUT:
Use these jacks to connect a tape recorder to the
mixer. Connect the Tape Out jacks to the recorder’s In/Record jacks. Connect
the Tape In jacks to the recorder’s Out/Play jacks. To avoid feedback, turn
down the Tape In Level control (#15) when recording.
22. AUX IN:
Use this jack to connect an auxiliary source (such as a tape play-
er, CD payer, etc.) to the mixer. This jack is a mono input - a stereo signal will
have to be mixed down to a mono signal by means of a summing device. This
input is especially useful for expanding the channel count of your P.A. by
adding an external mixer (see page 6).
