QSC PLD Series - Presets

Presets
Twenty factory presets pre-installed in the amp offer all the different combinations of amp channels that FAST allows.
Internal relays connect the channel outputs in accordance with how FAST has them arranged. For example, if A and B are
parallel, you can use either output connector—A or B—or both of them to connect the loudspeakers.
Presets F1 through F9 set up only the amp’s output configuration. F10 through F20 provide output configuration along
with basic DSP settings for the application described. You can modify or set any parameters and save the configuration in
in any of the 50 user preset slots.
The factory presets are identified by the prefix F and the user presets by the prefix U.
Factory Preset Display Description
F1
Four separate out-
put channels
Suitable for as many as four different signals into as many as four
different loudspeaker loads. Load impedances may vary from one
channel to another, as long as they are 2Ω or higher.
Input 1 goes to channel A; Input 2 to channel B; Input 3 to chan-
nel C; and Input 4 to channel D.
F2
Channels A and B
parallel; C and D
separate
Suitable for a high-power 2–4Ω full-range loudspeaker load and
two separate full-range loudspeaker loads of any impedance 2Ω or
higher.
Input 1 goes to the parallel channels A and B; Input 3 to channel
C; and Input 4 to channel D.
F3
Channels A and B
bridged; C and D
separate
Suitable for a high-power 4–8Ω (or higher) full-range loudspeaker
load and two separate full-range loudspeaker loads of any imped-
ance 2Ω or higher.
Input 1 goes to the bridged channels A and B; Input 3 to channel
C; and Input 4 to channel D.
F4
Channels A and B
parallel;
channels C and D
parallel
Suitable for two high-power 2–4Ω full-range loudspeaker loads.
Input 1 goes to the parallel channels A and B; Input 3 goes to the
parallel channels C and D.
F5
Channels A and B
parallel; channels C
and D bridged
Suitable for a high-power 2–4Ω full-range loudspeaker load and a
high-power 4–8Ω (or higher) full-range loudspeaker load.
Input 1 goes to the parallel channels A and B; Input 3 goes to the
bridged channels C and D.
F6
Channels A and B
bridged; channels
C and D bridged
Suitable for two high-power 4–8Ω (or higher) full-range loudspeak-
er loads.
Input 1 goes to the bridged channels A and B; Input 3 goes to the
bridged channels C and D.
