SETTINGS
The Settings Menu allows you to control various aspects of the Portable Headphone
Amplifier's performance. You can control the following factors.
Auto Input: When Auto Input is enabled, the amplifier will automatically select the
most recently connected input. The possible options are ON (Auto Input enabled) or
OFF (Auto Input disabled).
DAC Filter: DACs require a reconstruction filter to "convert" the discrete samples
into a continuous analog waveform. Usually this is a low-pass filter (LPF) with the
cutoff frequency being 1/2 the sample frequency with a very sharp roll-off
characteristic. Unfortunately, there is no such thing as a perfect reconstruction filter,
so that is why the AKM DAC and other DACs have selectable filter characteristics.
Your headphones and listening requirements vary, so experiment with the different
slopes to find your sound. The possible options are Normal, Slow 1, and Slow 2.
Reset All?: This function allows you to reset all of the settings to the factory default
values. To reset all settings, momentarily press the INCREASE button to change the
displayed value to ON, then momentarily press the ENTER/INPUT button to perform
the reset.
About...: Momentarily press the INCREASE or DECREASE button to display the
product name and software version.
Perform the following steps to adjust the various settings:
1.
Momentarily press the MENU/BACK button. The Display will show MAIN MENU [1/4]
EQ.
2.
Momentarily press the INCREASE button three times. The Display will show MAIN
MENU [4/4] SETTINGS.
