1. Resistive Load (RL) Jumper
Moving-coil phono cartridges often benefit from a low-value
resistor termination.
• Leave the resistive load jumper CLOSED to place a 200Ω
resistor load on the phono input.
• OPEN the resistive load jumper to place a 47kΩ resistor
load on the phono input.
2. Capacitive Load (CL) Jumper
Low-impedance moving-coil phono cartridges often benefit
from a capacitor termination.
• Leave the capacitive load jumper CLOSED to place a
10nF capacitor load on the phono input.
• OPEN the capacitive load jumper to place no capacitor
load on the phono input.
Note
• When both the capacitive and resistive load jumpers
are OPEN, custom loads are in parallel with the 47KΩ
input resistor. This parallel combination becomes more
significant as custom loads exceed 5KΩ in value. Use
the following formula if an exact termination value is
desired: [RL=1/(1/custom load+1/47KΩ)].
• Contact the phono cartridge manufacturer for specific
capacitive and resistive loading recommendations.
3. Input Gain (G) Jumper
Low-output (<5mV) phono cartridges often benefit from more
input gain. High-output (>5mV) phono cartridges often benefit
from less input gain.
• Leave the input gain jumper CLOSED to place 60dB of
gain on the phono input.
• OPEN the input gain jumper to place 40dB of gain on the
phono input.
4. Custom Load Screw Terminals
• Fasten the desired value resistor and/or capacitor to the screw
terminals to place a custom load on the phono input.
• In some cases, manufacturers recommend resistive loads
other than 200Ω or 47kΩ. The screw terminals accommodate
custom loads below 47kΩ.
