THE DEEPER VIEW 15

Focused means, the high frequencies are the loudest when you listen on the axis of the speakers. The high

frequencies are damped when you listen o-axis. Every speaker has a bit of this focus eect, but guitar

cabinets are really bad. The closer you stand by the cabinet, the more you get of axis and out of the focus,

because your ears are positioned much higher than the axis of the speakers. You will need quite a loud

volume to sit well in the musical mix on stage. Guess who are the victims? Your fellow musicians and your

audience in a small venue, who listen much closer to the axis of your speaker. Again they don’t hear what

you hear. And this might be the reason why guitarists are suspected to play too loud: It’s the focus.

Enough said.

The Proﬁler oers the possibility to run a guitar speaker cabinet, as mentioned. To make it sound perfect,

you have to bypass the virtual cabinet of the proﬁle by engaging “MonitorCabO” in the Master/Output

menu. If you don’t do that, you will run your sound by the virtual and real cabinet in a row, causing the rig

to sound mued and overdone.

If you switch o the cabinet in the STACK section instead, the virtual cabinet will be bypassed for all out-

puts.

The sound you get is not the raw pre amp or power amp sound of the proﬁle. Instead, the impedance

curve of the original cabinet that has been used for the original proﬁle is retained. That means, you can

use a solid state power amp or a digital (class d) power amp to drive your cabinet. It is not necessary, and

would be a bit contradictionary to use a tube power amp, even though you can.

This might require some more explanation: There are two main dierences between tube power amps and

solid state power amps. While solid state amps try to optain a linear frequency response, tube power amps

often create an “artistic” nonlinear frequency response.

Solid state amps oer a low output impedance that dampens the resonances of the speaker. Tube power

amps don’t dampen that well, and let the speaker act out their resonances, thus creating an individual fre-

quency responce in addition to the tube power amps responce. This is sometimes called “interaction of the

amp and the speaker” by whatever reason. But technically spoken a solid state amp interacts to a higher

degree with the speakers by actively dampen the individual resonances of the speaker.

This behaviour makes the sound of solid state amps and digital amps more predictable, since they do not

recolour the sound. It allows the Proﬁler to colour the sound by the original impedance curve of the origi-

nal virtual cabinet, bringing the sound very close to how the original amp used to sound “in the room”.
