VERY IMPORTANT NOTES:
Occasionally with certain congurations, you may experience
excessive hum or buzz. In this case, try connecting the Ground
connection from your turntable directly to your receiver/ampli-
er, thus bypassing the VP530.
If you connect the output of the VP530, either the RCA or head-
phone outs, without connecting a turntable to the input - you
will experience noise. The combination of the VP530 and the
turntable (with its RIAA equalization curve) - complete a crucial
circuit for proper operation.

INTRODUCTION
Thank you for your purchase of the Bellari VP530 Tube Phono Preamp.
The VP530 is designed to amplify an RIAA equalized phono signal to a
Hi-Fi level signal, and is intended for magnetic pickups. Since the unit
utilizes tube circuitry, the resulting output signal is more warm and
musical than solid state preampliers.
INSPECTION
1. Unpack and Inspect the VP530 package
Your VP530 was carefully packed at the factory in a protective carton.
Nonetheless, be sure to examine the unit and the carton for any signs
of damage that may have occurred during shipping. If obvious physical
damage is noticed, contact the carrier immediately to make a damage
claim. We suggest saving the shipping carton and packing materials
for safely transporting the unit in the future.

DESCRIPTION
GROUND CONNECTOR: Connects to the Ground of the phonograph.
INPUT: Stereo RCA jacks for connection to the phonograph.
OUTPUT: Stereo RCA jacks for connection to a stereo system or ampli-
er.
STEREO HEADPHONE/LINE OUTPUT: 1/4" Tip-Ring-Sleeve jack for con-
nection to any standard pair of headphones or earphones.
PWR INPUT: ROLLS PSU115 15V DC 700mA.
RUMBLE FILTER: High pass lter - eliminates frequencies under 20Hz.
MUTE: When pressed in - mutes the RCA outputs. The Headphone Out-
put will still have signal present.
FLAT/RIAA: Switches from an RIAA EQ'ed output to a FLAT output.
OUTPUT LEVEL: Adjusts the amount of signal to the RCA Outputs.
HEADPHONE LEVEL: Adjusts the amount of signal to the Headphone/
Line Output.
USB: USB output for connection to a computer or other usb device
input.
IMPORTANT USB NOTE:
When connecting the USB, your computer should recognize the
connection. We oer no support for using or setting up the USB, or
interfacing with applications. Please contact your dealer regarding
these issues.
CONNECTION/OPERATION
Connect your turntable to the VP530 as shown. The Outputs may be
connected to an amplier, recording device such as a cassette recorder
or computer sound-card, or a tuner Aux input. Only use a Tip-Ring-
Sleeve stereo plug in the Headphone Output. CONNECTING A MONO
PLUG IN THIS JACK MAY RESULT IN DAMAGE TO THE VP530.
Connect the PSU115 to the unit and an AC outlet or power strip.
Play a record on the turntable and adjust the Output Level and Head-
phone Level controls to the desired amounts.
Switch in the Rumble Filter to eliminate very low frequencies if needed.
Press in the Mute switch when you wish to mute the RCA outputs of
the VP530 (the Headphone Output will still be active).
VERY IMPORTANT NOTES:
First of all - turntables and tube equipment have a certain level of
noise. That's why the two technologies are essentially obsolete.
The VP530 is intended for use with Moving Magnet cartridges, not
Moving Coil. While a Moving Coil cartridge will work, you will be re-
quired to turn up the volume of the unit as well as your receiver/ampli-
er causing an increase in noise.
