Controls and Hook-Up
Front Panel
The front panel of the PrimaLuna models is made from machined aluminium, finished to complement
the blue metallic chassis. The following functions are controlled with the 4 silver buttons on the front:
play/pause; stop/open; next/previous; repeat current/repeat all (read further down the manual for
special instructions).
Rear Panel
Looking at the rear panel, you’ll note you have three outputs: one set of stereo analog outputs; two
digital outputs—one coaxial and one optical.

Tube Information
The 12AU7 and 5AR4 tubes will have a life of about 10,000 hours.
Here are some tips on using tubes:
•
Do not use treatments on tube pins or in sockets.
•
If you decide to experiment with other types of tubes, it is critical that you first turn the power off to
the CD player, then turn the volume down completely on your pre-amp AND also switch your
pre-amp to a different source. We recommend you not swap tubes in and out repeatedly because
every time you insert a tube, you increase the chance of loosening the tube sockets. It’s okay to
have fun, and we support that, but don’t go crazy and swap tubes in and out twenty times a day.
•
The ProLogue Premium CD Player has a warm-up time of just a few minutes. Although it is not
wise to leave tube components on 24 hours a day, you may leave this player on if you choose, but
it will result in more frequent tube replacement. Through experimentation, come to a conclusion
that fits comfortably with your lifestyle.
•
Break-in yields improvements. So, when your CD player is new, or when you re-tube it, it may
take a little time to settle in. There is however no fixed “time rule” for break-in.
•
IMPORTANT!
Please note that tubes can vary electrically, and by plugging in the wrong type of
tube you can damage the unit and void your warranty.
Common replacements:
•
12AU7:
ECC82, ECC802S, E82CC, 5814, 6189, CV4003.
•
5AR4:
GZ34, CV1377 are equivalent. 5V4G, 5T4, and 5Y3 will also function fine with small sonic
changes that you may want to experiment with. Do not use other types as damage may occur.
