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.

Break-in, Warm-up and Caring.

The sound of the Burson Composer 3XP improves steadily within minutes after powered-up.

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.
