Thank you for purchasing the Haer PH60B™ phono stage,
one of the best sounding and most versatile phono preamps
ever made. The PH60B will boost the signal from your turn-
table 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 PH60B is designed for a turntable that is equipped
with a moving coil (MC) cartridge, allowing for high quality
playback over balanced or unbalanced outputs. If your turn-
table is equipped with a moving magnet (MM) cartridge, please
consider purchasing the PH50B, which is specically designed
for these types of cartridges.

STYLUS
The Haer PH60B is a combination pre-preamp and RIAA preamp that
both increases the level to accommodate the moving coil, adds in the
RIAA equalization curve and then boosts the signal so that it can be used
by a typical high delity receiver.
ABOUT THE RIAA EQUALIZATION CURVE
The Recording Institute Association of America (RIAA) gured out that in
order to reproduce a vinyl recording effectively, the high frequencies have
to be exaggerated. Upon playback, the reverse lter must then be applied
– resulting in a at and natural sound.
Moving coil cartridges produce a much
lower output than a moving magnet. In
order to bring their gain up to a useable
level, between 60 and 70dB of gain
is required. This in fact is extremely
difcult to do without introducing noise
or artefact. This is why moving coil
preamps are more expensive.

SETTING LOAD FOR YOUR CARTRIDGE
The Haer PH60B is set up to accommodate various types of moving
coil cartridges. This is accomplished with a series of internal jumpers
that can be set for 25Ω, 50Ω and 100Ω plus a custom setting should this
be needed.
The PH60B comes factory set at 100Ω as this will accommodate about
90% of the cartridges used today. Your phono cartridge manufacturer
will suggest the appropriate load for its cartridge for optimal performance
– which should be found in the cartridge’s manual or web site. If your
cartridge requires a different load, simply take the cover off the PH60B
using a standard Phillips screwdriver and a HEX 5/64", carefully pull the
jumper from the 100Ω position and push it back on to the 25Ω or 50Ω
position to suit. Setting the load correctly will assure the most accurate
frequency response.
Some cartridge manufacturers may suggest a unique (specic) load to
optimize their cartridge’s performance. To address this, a fourth ‘custom’
position in the jumper section of the PCB allows a resistor to be soldered
in to suit. Simply have your dealer contact the Haer service depart-
ment with the required load and we will calculate the proper resistor. Your
dealer’s service department can then insert the part at a nominal cost to
accommodate your needs.

Turn off your system and connect the output from your turntable to
your PH60B. Make sure you use high quality coaxial cables with proper
shielding to minimize noise. It is also very important that you ensure the
ground connection from the turntable is properly and securely fastened
to your PH60B.
Using the Unbalanced Outputs
If you are connecting to a HIFI receiver use the RCA outputs on the
PH50B into a pair of line level inputs on the receiver. Do not use inputs
labeled ‘phono’ as these will apply the RIAA equalization curve a sec-
ond time, resulting in distortion and a loss of high frequencies.

Using the Balanced Outputs
The balanced XLR outputs on the PH60B allow you to connect to de-
vices with balanced inputs, including some home stereo receivers, and
pro audio equipment such as recording interfaces or mixing consoles.
This allows you to set up a turntable for playback in a home theater or
recording studio, or to convert your vinyl collection to a digital format
using recording software. Ensure that you are connecting to inputs that
are set for line-level operation. Once connected, should you encounter
buzz or hum from ground loops, simply engage the LIFT switch on the
front of the PH60B to lift the audio ground on the XLR outputs. The bal-
anced outputs on the PH60B can be set between two different outputs
levels using an internal push-switch. The default setting is +4dB with
the switch in the ‘out’ position, and -10dB with the switch pushed in.

The balanced outputs on the PH60B can be set between two different
output levels using an internal push-switch. The default setting is +4dB
with the switch in the ‘out’ position, and -10dB with the switch pushed
in. To access the switch follow the instructions on pg.4 and remove the
necessary screws to open the PH60B.
Most consumer audio devices are set to operate at a -10dB line level,
while pro audio equipment such as mixing consoles and recording in-
terfaces will be set to accept a higher output +4dB level. Check with the
manufacturer of your receiving device to determine whether it operates
at -10 or +4dB.
