Thank You.
All of us at Burson Audio would like to say thank you, and congratulations for purchasing the Burson
Composer 3XP. We sincerely believe that your Burson Composer 3XPP is an intelligent investment that
will bring you many years of musical enjoyment and satisfaction.
We understand how eager you are to begin listening and we want you to become familiar with the full
capabilities of the Burson Composer 3XPP. However, before powering on the device, we encourage
you to look through the manual.
Team Burson
The less the equipment tampers with the music, the greater the music becomes. This has been the
core design philosophy of Burson Audio since 1996. If the equipment is honest and transparent then
the proper tempo, dynamics and tone will materialize as a natural expression of the music and it
becomes unnecessary to flavor the original sound. We believe that this ideal can never be achieved
through standard circuitry building blocks such as opamps, IC regulators or even standard
transformers. Instead we work towards this ideal through the research and development of
customized solid-state circuitries that are developed specifically to suit our applications. Only then
will each and every component involved be pushed to their performance peak. And only then will the
end result be consistent with our idealism.

XLR to RCA Output:
To achieve an ideal sonic performance, the XLR outputs of the Composer 3XP are direct coupling. ie. It
has no coupling capacitors or transformers on the audio signal path.
However, direct coupling outputs are not compatible with off-the-shelf XLR to RCA adaptors like the
ones showing below. Using such adaptors to connect the C3X to any single-ended amplifier with RCA
inputs will damage the internal opamps of the C3XP.
Therefore, to safely connect the Composer 3XP to any single-ended amplifiers, please use the
transformer type of adapters below.
Unpacking
After carefully unpacking your Burson Composer 3XP, inspect for any shipping damage and call your
dealer immediately if any is found. Do not plug your Burson Composer 3XP into any outlet if you find
shipping damage. Please save all packing materials so the unit can be easily and safely shipped if the
need arises.

Depending on the resolution of the system and the attentiveness of the listener, you may find that
the sound continues to improve over the first several weeks of operation.
Never, connect or disconnect the headphone jack or the RCA cables from the Composer 3XP while
music is Composer 3XPing. This could damage the Composer 3XP. After your listening session, please
disconnect the headphone jack from the Composer 3XP to prolong the working life of its headphone
output socket.
