Thank you for purchasing the HA543. We spent a consider-

able amount of time designing and developing the HA543.

Hundreds of hours listening and improving the design. We

hope you enjoy using the HA543, and that it makes listen-

ing to your vinyl collection rewarding. We sincerely appreci-

ate the opportunity to build a product for you and participate

in your love of quality music and sound. We love what we

do and we’re happy to help. All Bellari products are hand

built in Salt Lake City, Utah by people who care about high

jack or XLR jacks.

2 - Connect the supplied PS27s adapter to the

jack labeled “POWER.” Do not use any other

adapter, or the unit might not be happy and you would need

some repair work done. Reversed polarity adapters will

cause damage.

3 - Optional: Connect the RCA out to

your other equipment (this is also called a pass thru or

preamp out).

4 - Connect your headphones to the jack, marked “head-

phone”. You can use eigther the 1/8” or 1/4” jack or both at

the same time. When using the headphone the RCA “out”

is still active. The “mute” switch will only mute the head-

phones the RCA out is always active.

experince.
