Explanation of terms

MM/MC cartridge

There are two types--MM (Moving Magnet) and MC (Moving Coil)--of
cartridges for turntable. As the output levels for these two types of
cartridges differ, the setting of the phono equalizer that is mounted in this
unit must be switched according to the type of cartridge for your turntable.
The setting can be switched by the cartridge selector knob on the main
unit. (v p. 8)

Speaker impedance

This is an AC resistance value, indicated in Ω (ohms).
Greater power can be obtained when this value is smaller.

Protection circuit

This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
