Depending on the source it might be necessary to flatten the input signal to receive an accurate
sound signal. This could be necessary especially in cars with basic OE speaker system without
separate tweeters. Some of the OE headunits of those cars are provided with an extreme treble
volume to get more treble sound out of the broadband speaker.
You can adjust the input EQ for each source separately.
You can adjust the Gain from -15 dB to + 15 dB
F0 means the frequency you would like to adjust.
You can choose a frequency from 20 – 20'000 Hz for each band. A popup window appears to
enter the value of the center frequency you want.
The Q factor (Q) determines the effect of the EQ filter (bandwidth) on the frequency band around
the chosen center frequency f0.
Example1: f0 = 1000 Hz
desired bandwidth of EQ filter = 1000 Hz (i.e. 500 Hz – 1500 Hz)
Q = 1
Example2: f0 = 1000 Hz
desired bandwidth of EQ filter = 200 Hz (i.e. 900 Hz – 1100 Hz)
Q = 5
Q factors from 0.3 to 9.9 are possible.
Noise Gate
The "Noise" function is intended to reduce the back ground noise of the head unit. If back
ground noise of the head unit is audible, increase the Noise Gate level by sliding to the left until
the noise disappeared.

Output EQ
You can create your sound according to your settings in the EQ menu. Depending on the grade
of required accuracy, you can adjust up to 31 bands of the parametric equalizer.
In the line „f0" tap on the band you want to adjust. A pop-up window appears to enter the value
of the center frequency you want. Confirm with „Ok". In the line „Q" tap on the band you want to
adjust. A pop-up window appears to enter the value of the Q factor you want. Confirm with „Ok".
Instead you can also touch "-" or "+" to adjust the Q factor in 0.1 steps.
The Q factor (Q) determines the effect of the EQ filter (bandwidth) on the frequency band around
the chosen center frequency f0.
Example1: f0 = 1000 Hz
desired bandwidth of EQ filter = 1000 Hz (i.e. 500 Hz – 1500 Hz)
Q = 1
Example2: f0 = 1000 Hz
desired bandwidth of EQ filter = 200 Hz (i.e. 900 Hz – 1100 Hz)
Q = 5
Q factors from 0.3 to 9.9 are possible.
If required, you can choose independent equalizer preferences for each channel separately or
for all left and right channels together. Simply use the button "Combine" in the upper right and
choose to copy the values from the left channels to the right one or right to left.
To reset all settings to „0", tap the „All Reset" button in the upper right corner. If you just want to
try out the presets and then go back to your personal preferences, exit without saving the app,
and then restart. The app will then load your saved preferences from the amplifier.
The EQ settings also apply to the corresponding preamp outputs.
