Front panel overview
Front panel description
The front panel of all PMQ amplifiers is identical among all the different models. All models
are including an USB port, LCD display and rotary selection dial.
USB port:
A USB port is provided on the left side of the front panel. This is used for inserting flash drives
with configuration files to load into the amplifier or duplicating system configuration files to
the inserted medium. The inserted flash drive shall support FAT32 filesystem.
Graphical LCD display:
A clear system overview and intuitive user interface is provided on the 2.5” graphical LCD
display. This true colour display provides a clear overview of the amplifiers operation mode
guaranteeing an user friendly experience when browsing through the menu structure.
Rotary selection dial:
Browsing through the menu structure and adjusting parameters is made easy with the rotary
selection dial. This multifunctional rotatable dial allows easy one-hand operation throughout
the entire menu structure. Browsing can be done by turning it while actions will be taken
when pressing it.
Channel selection buttons with indicator LED’s:
Channel selection and monitoring is made easy through a selection button together with four
indicator LED’s for every channel. When pressing the button, the menu structure will call the
settings of the corresponding channel, allowing adjustment of the parameters.
The LED’s give a continuous indication of the operation of the corresponding channel. The
green Signal LED illuminates whenever a signal is present, while the -20dB LED illuminates
when the input signal exceeds the - 20 dBu level. The Clip LED illuminates when the
corresponding channel is working at maximum level. To ensure the best signal-to-noise
ratio, the Clip LED may only illuminate at peak levels.
