Headphone Socket
This
6.35mm (1/4”) stereo (Tip Ring Sleeve) jack socket can be used for
monitoring any of the phones audio sources.
In the settings menu it is possible to adjust the audio level of each of these
sources into the headphone’s mix circuit to suit the way that you want to work.
Headphone volume is adjusted by using the front panel ‘Control Shaft
Encoder’ (see no 6).
The headphone amplifier uses one of our clever designs that allows both high
and low impedance headphones to be connected without any degradation of
signal and even allows mono earpieces to be connected without any damage
to the circuit.
4.
USB Update Socket
This is a micro USB socket.
It is used for updating the devices firmware (the software that runs on the
internal microprocessors and makes it work).
5. Recessed Reset Button
This
button should only ever be used if advised to by Glensound’s technical
support team.
The button itself is recessed about 13mm inside the unit and requires a
straight narrow firm object (such as a straightened paper clip) to operate it.
The head of the button is only about 3mm in diameter so the paper clip must
be inserted level and straight to make contact.
When operated the button only moves about 1mm so if you are advised to
use it please do not press too hard with the paper clip.
6. Control Shaft Encoder
This rotary shaft encoder can be turned and also pushed and used as a
switch. It is illuminated and the colour is used to indicate different operational
states.
In general day to day use the encoder can be turned and used to adjust the
headphone volume.
If in a settings page with an adjustable level control (such as the display
brightness setting or sound settings sounder volume control) then the encoder
can be turned to adjust the settings value.
During normal day to day use the encoder is illuminated red to show that no
call is in progress, it flashes green to show that there is an incoming call and
steady green indicates that a call is in progress.
