Fractal FM9 - NEUTRAL (“FLAT”) POWER AMP & GUITAR CAB

30
4 SETTING UP
NEUTRAL (“FLAT”) POWER AMP & GUITAR CAB
Global Settings: Modied (see below)
Presets: Factory or Custom
This popular setup uses a full range flat response (“FRFR”) power amp with traditional guitar speakers. Such
amps are usually solid-state and designed specically for pro audio or FRFR guitar. They are ideally tonally neutral
and dynamically transparent though some may have basic tone controls and/or some effect on “feel.”
The FM9 performs amp modeling but NOT speaker cab simulation. Effects can be used as desired in any position.
DISABLE SPEAKER CAB MODELING
Using real speakers and modeled speakers at the same
time would be redundant, so this setup requires you to
disable or remove the FM9 Cab blocks. You can do this
manually in each preset, or take advantage of an easy
global setting:
 Navigate to SETUP: Global Settings: Cong.
 Change Cabinet Modeling to “BYPASSED”.
A “NEUTRAL” POWER AMP...
In comparison to the neutral power amp used here,
the power section of most guitar amps has a very
pronounced effect on tone and feel. Here, however,
the FM9’s “Power Amp Modeling” simulates these
characteristics. This has several benets. First, since
one amp’s power section can be so different from
another’s, a modeled power amp ensures accuracy
when you change amp model types. The power amp of
a “deluxe” is extremely different the power amp of a
“recto”, for instance. Therefore, do NOT disable power
amp modeling on the FM9 when using a neutral power
amp.
One setting you should change, however, is Output
Mode, located near the top on the Advanced page of the
Amp block’s edit menu. Set it to “SS PWR AMP + CAB”.
In this mode, virtual speaker compression behaves
differently, relying on the real speaker for compression
while still simulating speaker interaction with the virtual
power amp.
CONNECTIONS
