XSP-1
5. Phono Ground
The Phono Ground is typically used to provide a clean solid ground for a turntable (if it
comes with a ground lead), but may also be used to ground the XSP-1 chassis to other
equipment as well.
6. Phono Input
This input is used to connect a turntable using a Moving Coil (MC) or Moving Magnet
cartridge. This input includes the extra gain and RIAA equalization required for a phono
cartridge and cannot be used for line level inputs. Most external phono preamps output a
line level signal, which must be connected to one of the other inputs on the XSP-1. (If in
doubt, please contact Emotiva Tech Support or the makers of your phono preamp.)
7. (MC) Impedance Selector
Allows you to select different load impedances when using a moving coil phono cartridge.
This switch is only active when the Moving Coil input is selected. Consult the maker of your
cartridge for suggestions about choosing the proper setting; or simply choose the one that
sounds best.
8. Moving Coil (MC) / Moving Magnet (MM) Cartridge Selector
Selects the gain appropriate for either a Moving Coil (MC) or Moving Magnet (MM) type
phono cartridge. Moving Coil cartridges usually have much lower output, and require much
higher gain, than Moving Magnet types. (There are, however, some Moving Coil units that
have higher output and are intended to be treated as Moving Magnet cartridges. There are
also passive transformers available , which connect between the cartridge and the preamp,
and which raise the output of a MC cartridge to MM levels.) If in doubt, consult the maker of
your cartridge or transformer for more information.
Note: Connecting a MC cartridge with the switch set to MM will generally result in
very low (insufficient) output and excess noise; connecting a MM cartridge with
the switch set to MC will usually result in overloading and distortion; neither is
recommended.
9. Full Range / High Pass Selector (for Main Outputs)
To make the Main Outputs of the XSP-1 full range (and disable bass management for the
Main Outputs), set this switch to the left (away from the High Pass adjustment screw).
Setting this switch to the right (towards the adjustment screw) enables bass management
for the Main Outputs. When bass management is enabled, the Main Outputs carry only the
high frequency part of the audio spectrum (the crossover point is set using the High Pass
adjustment (10)).
When the HT Bypass (Home Theater Bypass) mode is enabled, bass management is
entirely bypassed, and the Main Outputs carry a buffered copy of the signal being received
at the Home Theater Left and Right Inputs.
