4.4 Headphone level
Use this control to adjust the overall headphone output level
4.5 Headphone output
Use this output to connect your headphones. Make sure that your headpho-
nes are not below 8Ohm in resistance otherwise you may damage the HP6E.
4.6 Power switch
This switch is used to switch the HP6E ON or OFF. Make sure correct
voltage is selected on the unit before switching the power ON.
5. HP6E Back panel
The back panel has 4 stereo 1/4” (6.5mm) inputs, a MIX input, a power cord connec-
tor and a Voltage selector switch.
5.1 Mix input
Use this input to connect audio signal you may want to mix into every
headphone channel. If you only have a mono signal and want both sides
of the headphone to operate then use the LEFT input.
5.2 Selected signal inputs
Use these inputs to connect an audio signal which individually can be
selected by any one of the 6 headphone output channels. If you only have
a mono signal and want both sides of the headphone to operate then use
the LEFT input.
5.3 Link function
Left/right inputs 1 are mirrored at the LINK output. This allows you to
feed the source signals, daisy-chain style, to additional units, for ex-
panding the system. Set your first HP6E to ‘Master’ and your second
HP6E to ‘Link’. Connect the two HP6Es with one TRS cable.
5.4 Voltage selector and power cord input
Make sure the correct voltage is selected before using or connecting
any power connectors to the HP6E. Failure to do so will cause da-
mage to the unit.
6. APPLICATION
Using the HP6E
Make sure the HP6E is switched OFF and that all the volume levels are set to the
minimum amount before connecting any headphones for the first time. Make sure the
right voltage has been selected in the back of the unit and then power the unit ON.
Connect an audio signal to one of the inputs at the back of the unit and then your
headphones to one of the outputs on the front of the unit. Select the appropriate input
on the front panel corresponding to the input you have used at the back of the unit
and slowly increase the level of the headphones.
