Thank you for purchasing the Haer PH50B™ phono stage,

one of the best sounding and most versatile phono preamps

ever made. The PH50B will boost the signal from your turn­table and apply the necessary RIAA curve, allowing you to
connect to a HIFI playback system, a pro audio console input

or a recording interface.

Before making any connections, make sure your audio system
is turned off. This will help avoid loud turn-on and connection

transients that can damage more sensitive components such

as tweeters.

The Haer PH50B is designed for a turntable that is equipped
with a standard moving magnet cartridge, allowing for high
quality playback over balanced or unbalanced outputs. If your
turntable is equipped with a moving coil cartridge, please con­sider purchasing the PH60B, which is specically designed for

these types of cartridges.

ABOUT MOVING MAGNET
CARTRIDGES

Moving magnet (MM) cartridges

tend to produce a lush, mellow

sound. Most MM cartridges have
replaceable styli. Their high voltage

output, variety, and the availability

of stylus replacement make moving
magnet cartridges a great choice for
the beginner and audiophile alike.

The Haer PH50B is specically designed for moving magnet cartridges.
It will boost the signal to produce a -10 dB output while incorporating
a well dened RIAA curve preserve and transmit the original program
material with minimal coloration.

ABOUT THE RIAA EQUALIZATION CURVE

The Recording Institute Association of America (RIAA) gured out that in
order to reproduce the recording effectively, the high frequencies have to
be exaggerated. Upon playback, the reverse lter must then be applied –
resulting in a at or natural sound.
