The Hafler 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 (specific) 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 Hafler 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.
