3.1 Front Panel Layout
not depressed, the left and right outputs will carry
the left- and right-channel signals, respectively.
Monitor Level. The Monitor Level knob controls
the volume of the rear-panel outputs.
Monitor Mute. The Monitor Mute button mutes
the main rear-panel outputs, which is handy when
you only want to use the front-panel headphone
outputs. This is especially helpful when recording
in front of a computer and studio monitors: you
can simply mute the signal going to the monitors
rather than turn down the Monitor Level.
3.2 Back-Panel Layout
Left/Right Balanced Inputs. These line-level
inputs should only be used for signals from sources
that do not require preamplification, such as CD
and MP3 players, mixers, and audio interfaces.
Left/Right Balanced Outputs (Monitor/Thru). These
are the line-level outputs for the HP4. The Monitor
Level knob on the front of the unit controls their output
level. These outputs can be used as a Monitor Thru
or to connect another HP4 for additional headphone
distribution. (See Section 2.1 for hookup diagrams.)
Power-Supply Connector. This is the
connection for the external power supply.
