INPUT LOADING SWITCHES
To set the input loading, there are two eight-position switches, one for each
channel, located on the rear panel. Refer to your cartridge owner's manual to
determine proper input loading settings. The factory setting for input loading is
47,000 Ohms. The chart below provides a general guide to choosing Resistive
Loading settings appropriate to your cartridge. BOLD settings are listed on the back
panel.
Switch #1 controls capacitive loading, which is often used with moving-magnet
cartridges and has little effect on moving-coil cartridges. When using a moving-coil
cartridge, you can try both capacitive loading positions to determine the effect.
CAPACITIVE LOADING (SWITCH #1): OFF=100pF; ON=200pF.
Switches #2-8 control resistive loading, which is primarily used with lower-output
moving-coil cartridges. Most moving-magnet along with medium and high-output
moving-coil cartridges use approximately 47,000 Ohms. Low-output moving-coil
cartridges typically use 2000 Ohms or less. Check the chart below and select the
closest loading value to the cartridge manufacturer's recommended value. Typically,
a lower resistive setting provides increased focus and tighter bass, while a higher
setting provides more openness. Use a non-metallic object to select the proper
settings, flipping the switch UP to activate the ON setting.
