Stereo Home Theater Pass Thru
Your PrimaLuna Tube Preamplifier or Integrated Amplifier might be equipped with a home theater pass
thru that allows you to enjoy your stereo source material and the 2 main channels of your separate home
theater processor. The home theater passes thru completely removes the preamp section from the
signal path.
Connecting Your Surround Sound Component
To avoid damaging your equipment, always make sure everything is turned off and unplugged from the
wall before connecting your components. Connect your stereo sources and speakers as normal.
To integrate your PrimaLuna Tube Preamplifier or Integrated Amplifier into your home theater system,
take the front left & right preamp outputs from your A/V processor or receiver and plug them into the “HT”
input on the back of the PrimaLuna Tube Preamplifier or Integrated Amplifier.
When you want to watch a movie, simply turn the PrimaLuna Tube Integrated Amplifier on, and switch
the input to “HT.”
Attention: double-check if the volume of your home theatre processor is at
minimum!
Now control the volume via your home theater processor as normal.
We recommend you go into the setup menu of your processor to match the levels of the front Left &
Right speakers to match the volume of your center channel. Consult your processor’s manual for more
information.
Ultralinear – Triode Switching
Your EVO 300 and 400 integrated amplifier 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 DiaLogue Premium always starts in Ultralinear mode when powered up. Centered behind the front
panel is a two-color LED which indicates 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.
