Ultralinear – Triode Switching
Your EVO 300 and 400 poweramplifier affords you the opportunity of switching between Ultralinear and
Triode modes by remote control. You need not turn off the amp to do so; you can switch while the unit is
operating. Although a faint click might be heard through your speakers, it is in no way harmful. Your EVO
300 and 400 poweramplifier always starts in Ultralinear mode when powered up. However, if you switch
off your poweramplifier while being in Triode mode, it will be in Triode mode when switched on again.
Centered on the front panel you find two color LEDs which indicate the mode in which the amp is
functioning: Red—Ultralinear; Green—Triode.
Ultralinear Mode - Triode Mode
The term ultralinear design exerts a tighter grip on the speakers and produces music more likely to be
described as accurate, dynamic, with great inner detail. The top and bottom end take on more “pop” and
excitement. Triode sound is best described as warmer on top and bottom, a little compressed, with the
midband now slightly more pronounced. The sound is more relaxed. In absolute terms it will not play as
loud as maximum power drops by roughly half compared to Ultralinear.
