Stealth SP-1 Input Selector and Phono Preamp
4. Ground lug
Use this lug to connect a ground wire from your turntable to minimize noise and hum.
Note: Not all turntables provide a separate ground lead. If your turntable
provides a separate ground lead it should normally be connected to this lug
for best hum and noise performance.
5. Phono Input
Connect the stereo outputs from your turntable to this input.
Note: The Phono Cartridge Type switches (1.) must be set to the correct
position for the cartridge you have installed in your turntable, and, if you have
a moving coil cartridge, the Cartridge Load switches on the bottom of the
SP-1 should be set to the value recommended by your cartridge manufacturer.
6. Line level Analog Inputs
Connect your line level stereo analog sources to these inputs.
7. IEC AC power inlet
Use this connection to provide AC power to the Stealth SP-1. A high-quality commerical
AC power cord is provided with the SP-1. You may substitute any IEC power cable of
your choice.
Setting The Cartridge Load Switches
If your turntable uses a moving coil cartridge, then you must set the Phono Cartridge
Type switches (1.) both to MC. If you choose the MC (moving coil) setting, you will
also be able to configure the resistive load seen by the cartridge. This setting will
change the way the cartridge sounds, and most manufacturers will offer advice on the
best value to choose. (Feel free to change this value if you prefer a different sound; it
won’t damage your cartridge.) To choose a particular value of resistive load, set the
associated switch to On.
Note: The Cartridge Load switches are located on the BOTTOM of the SP-1.
Note: The switches for both channels should be set the same, and only one
load selector switch per channel should be activated at a time. To choose load
values, set each switch TOWARD THE CENTER (towards the writing that shows
the value).
Note: Load selector switches are only active in MC (moving coil) mode.
