MANUAL

On power up the DSP amp will load stored EQ, limiter and output attenuation 
settings. Gain will be at mute. In normal use a user can only use the volume control 
(Gain). By pressing the control encoder for approximately 4 seconds the settings 
menu will be displayed.

The settings menu contains the following submenu’s:

• Gain
• 

EQ Low

• 

EQ Mid

• 

EQ High

• 

LIM TH  (threshold)

• 

LIM ON (Limiter on or off)

• 

ATTENUATE (Output attenuation)

By pressing the encoder again the selected submenu will be entered and settings can 
be live adjusted. After a short press the new setting will be stored and the menu falls 
back into volume control. If the encoder is untouched for approximately 3 minutes, 
the open (sub)menu closes and control falls back into normal volume control. 
Adjusted settings will be stored and active. After a power cycle all stored settings 
will be loaded. 

WARNING!

On shipping and by default the output limiter and output attenuation are 
disabled. Without proper adjustment to the type of headphone used the 
HPH DSP can produce over 100dBA @ +6dBU input level and can cause ear 
damage! Take proper precautions and make proper settings to ensure the 
maximum legally allowed output level is not exceeded. AeroAudio strongly 
advises to adjust limiter and output attenuation to be set at 85dBA maximum 
output level.

AeroAudio can not be held responsible for any type of damage or injuries in 
short- or long-term caused by improper installation or use.
