CONNECTION CONNECTOR TYPE WHAT IT DOES
AC Power Input IEC Power Connector Powers the 506E. Connect only to the
AC power source marked on the rear
panel.
Headphones 1–6
OUTPUT 3-conductor TRS (tip-ring-sleeve) For connecting to the optional
Symetrix HR-1 Headphone Remote.
The minimum impedance of this
output is 8 ohms (see Calculating the
Maximum Amplifier Load for combin-
ing headphone impedances). Be sure
to include headphones connected to
the corresponding front-panel output
jack in your impedance calculations.
The tip contact is the left channel.
DIRECT INPUT 3-conductor TRS (tip-ring-sleeve) Allows separate access to the inputs
of each of the 6 headphone amplifi-
ers. When an input is not used, it is
normalled to allow signal from the
506E’s program inputs and cue input
to be fed to this headphone amplifier
section. When a TRS 1/4" connector
is plugged into this jack, it breaks the
signal path, allowing the user to
insert a different line-level signal into
this amplifier section only.
For example, vocalists could use the
first 5 headphone outputs to monitor
the full program, and, by patching a
click track into DIRECT INPUT 6, the
drummer could use headphone output
6 to listen to just the click track.
