Inputs, Controls & Remote Function
PrimaLuna's front panels are made from machined aluminum, finished to match the black/blue metallic
chassis. The volume is controlled with the knob on the left, source selection is on the right. Both
volume and source can also be selected by remote control. Your sources are labeled CD, Tuner, Aux 1,
Aux 2 (no functional differences between these) and HT (Pass Thru; volume fixed!!). The heavy metal
remote control that comes with your PrimaLuna ProLogue Premium Integrated Amplifier can be used
for selecting sources and adjusting volume. It also can be used to control functions on PrimaLuna's CD
player. The power switch is located on the left side of the amp, just behind the front plate, the
EL34/KT88 switch on the right side of the amp, just behind the front plate.
Looking at the rear panel, you will note you have four pair of stereo inputs, one pair of HT Pass Thru,
one ground connection (for optional phono) and the pair of speaker terminals. Attach the positive (+)
from your loudspeaker to the 4 or 8 ohm terminal that most closely matches the average impedance of
your loudspeakers according to their manufacturer's specifications. The negative (-) from your
loudspeaker attaches to the 0 Ohm terminal.
Tip: Experiment using the 4 or 8 Ohm positive (+) terminal to find the best match for your speakers. Do
not make any assumptions. Trust your ears.

PTS™ - Premium Tube Selection™
Our "standard" PrimaLuna SilverLabel tubes are pre-selected using our simple 60 out of 100 rule and
assuch, are already "special" when compared to other standard tubes on the market. Out of 100 tubes
which have passed the final quality control from the manufacturer, we are allowed to select and keep
the 60 best pieces. The other 40, which are in no way defective (these just do not belong to the best
60), go back to the manufacturer and are used to supply other clients.
Additionally, we keep an eye on all tubes still manufactured today and if special, high quality tubes
become available, we consider them as candidates for our GoldLabel tubes. Normally these are tubes
which are still in production—we don't want to offer minor quantities of N.O.S. (New Old Stock) tubes
as PrimaLuna GoldLabel tubes.
Currently we have available 12AX7 and 12AU7 GoldLabel tubes but will be expanding our inventory in
the near future. Please feel free to inquire.

EL34/KT88 Switch

The ProLogue Premium Integrated Amplifiers—as well as the Premium Stereo and Mono amplifiers—
come with an EL34/KT88 bias switch. This means that by the flip of a switch you can choose the
optimum bias setting for EL34s or KT88s. No hassle with screwdrivers, no messing around with meters
etc. If you swap tubes, simply flip the switch for optimum bias!
And should you use the "wrong" bias setting for the tubes in use, don't worry. It just means you did not
choose the "optimum" bias setting as decided by the PrimaLuna design team. Some PrimaLuna
owners even like to "play" with this switch to see what is the optimum bias setting for their
circumstances and some go even further and play with this switch while having a mix of EL34 and
KT88 within one channel. All is possible due to the PrimaLuna Adaptive AutoBias Circuit.
