8. Configuring the Joplin Joplin Joplin Joplin
The Joplin is a very versatile unit, with plenty of features to tailor its behaviour to the
source being used and the music program being played back. To configure all the features
and parameters, a menu can be accessed from both the front panel controls and the
remote.
The menu has a simple one-level structure in which all the parameters are accessed
sequentially. The following parameters can be set:
• Input gain;
• Input choice;
• Sampling frequency;
• Resolution;
• Equalization curve;
• Display dimming;
• High-pass (anti-rumble) filter;
• Low-pass (anti-hiss) filter;
• MPX filter.
All parameters are stored in a non-volatile memory, so that they are recalled after every
power-on.
8.1. Navigating the menu by the front panel controls
The menu is accessed by pressing the encoder knob once (Figure 1, 2). The first
parameter (Input gain) is displayed along with its current value. Successive pushes on the
encoder knob without rotating it will allow to access other parameter, in the order listed
above.
When the desired parameter is displayed, its value can be changed by simply rotating the
encoder knob. To confirm the new value for the current parameter, press the encoder knob
one last time.
To exit the menu without changing the displayed parameter value after the knob has been
rotated, press the Standby/Exit button once (Figure 1, 1). Anyway, the system resets to the
idle state after some seconds from the last operation on the knob.
8.2. Navigating the menu by the IR remote
The menu is accessed by pressing the Menu/Exit button on the remote once (Figure 3, 2).
The first parameter (Input gain) is displayed along with its current value.
To display other parameters, use the arrow up and arrow down buttons (Figure 3, 3).
