Line Output and Zone 2 Output
The line output is a 2-channel version of the selected input with a fixed output level. Use this output with a headphone
amp or similar device with built-in volume control.
The Zone 2 output, which has an independent volume control, is used in two ways:
• For independent source selection, connect the source using an analog input, optical/ coaxial input or HDMI.
• Note, for AVM 70/90, external amplification is always necessary when adding Zone 2 speakers.
• Note, for MRX 740 and MRX 1140, if you are using all available sets of binding posts for the main zone's speaker
system, external amplification is necessary for Zone 2. Otherwise, some unused channels can be assigned to power
Zone 2 which can be found in the Speaker Setup > Amp Matrixing menu and will be explained further in the Speaker
Setup section.
Analog Inputs
There are five RCA line inputs. On AVM models, the fifth analog input is a dedicated phono input suitable for a
turntable with a moving-magnet (MM) phono cartridge. When using a turntable, connect the ground wire from the
turntable to the screw terminal next to the phono inputs to prevent excessive hum. Note, if you are using a turntable
with a moving-coil (MC) phono cartridge, you will need a separate phono preamp which will connect to the standard
analog inputs because there will not be enough gain on the (MM) input.
