The HPH DSP TM is a studio quality DSP controlled class AB headphone amplier
with gain control, three-band EQ and limiter.
Three key features make this ampliers outstanding for studio use. The rst feature
is the high slew rate that prevents odd order distortion anomalies.
The second feature is current-on-demand at the output that enables the amplier
to respond quickly and linearly when necessary without risk of output distortion.
When large amounts of output power are suddenly needed, the amplier can
respond extremely quickly without raising the noise oor of the system and
degrading the signal-to-noise ratio.
The third feature is the gain-independent frequency response that allows the full
bandwidth of the amplier to be used over a wide range of gain settings.

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.
