VERY IMPORTANT NOTES:
-Occasionally with certain configurations, you may experience exces-
sive hum or buzz. In this case, try connecting the Ground connection
from your turntable directly to your receiver/amplifier, thus bypassing the
VP530.
-If you connect the output of the VP530, either the RCA or headphone
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.

FAQ:
Q:The VP530 has no power switch should I leave it on all the time or only
turn it on when needed?
A: Always turn the unit off when you are not using it. This will help keep
your VP530 sounding like new for a longer time, and saves electricity.
We recommend connecting your setup to a outlet strip so you can turn
on all your phonograph equipment at once.
Q:What is a N.O.S. tube?
A: N.O.S. refers to (new old stock) it is a tube that was manufactured
long ago and never used. These tubes are very sought after. They may
or may not sound any better, but it is generally thought that most N.O.S.
tubes are better in many ways over new foreign manufactured tubes.
Q: What kind of tubes can I use in the VP530?
A: Tubes that can be used in the VP530 are:
12AX7 - The industry standard for preamp tubes.
12AX7A - Same as a 12AX7 but generally has a slightly higher output.
7025 - This is the Military part number for a 12AX7.
ECC83 - This is the same as a 12AX7 it is the European part number.
12AX7WA - This is a 12AX7 with slightly lower output.
5751 - This is a Military part number for a 12AX7WA.
There are many other tubes that can be used, but you get where this is
going they are essentially the same tube with different part numbers do-
ing almost exactly the same thing.
Q: What is the best sounding tube I can get for the VP530?
A: This is an unanswerable question. Everyone has different tastes. It
is up to the individual to decide as all tubes sound slightly different. For
me the best tube I have ever heard in a VP530 was a N.O.S. Telefunken
tube.

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 sig-
nal, and is intended for magnetic pickups. Since the unit utilizes tube circuitry, the
resulting output signal is more warm and musical than solid state preamplifiers.
INSPECTION
1. Unpack and Inspect the VP530 package
Your VP530 was carefully packed at the factory in a protective carton. Nonethe-
less, 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.
2. We recommend registering on-line at www.rolls.com.
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 amplifier.
STEREO HEADPHONE/LINE OUTPUT: 1/4" Tip-Ring-Sleeve jack for connection
to any standard pair of headphones or earphones.
PWR INPUT: 12-15 VDC 300-1000mA.
RUMBLE FILTER: High pass filter - eliminates frequencies under 20Hz.
MUTE: When pressed in - mutes the RCA outputs. The Headphone Output will
still have signal present.
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.
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 required to turn up the volume
of the unit as well as your receiver/amplifier causing an increase in noise.
CONNECTION/OPERATION
-Connect your turntable to the VP530 as shown.
-The Outputs may be connected to an amplifier or recording device such as; a
cassette recorder, computer sound-card input, Headphone amp, ect. Only use a
Tip-Ring-Sleeve stereo plug in the Headphone Output. CONNECTING A MONO
PLUG IN THIS JACK WILLRESULT IN PERMANENT DAMAGE TO THE VP530.
-Connect the AC adaptor to the unit and an AC outlet or power strip.
-Play a record on the turntable and adjust the Output Level and Headphone 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).

FAQ:
Q: Does the tube need time to warm up before use?
A: Yes, it will be usable in about 30 seconds. Longer warm up times are
not needed, there is no benefit to warming the tube up longer than 60
seconds. (warm up) simply means plugging in the power supply.
Q: What is the life expectancy of the vacuum tube in the VP530?
A: 10 to 50 years (or longer if you do not use the unit very often) if you
use it more often it will have a shorter life, like a light bulb. 10 years if
you have the unit on 24/7 every day all the time. 15 years if you use the
unit once a day. 25 years if you use the unit a couple times a week. More
than 40 years if you use the unit a few times a month.
