User Interface Functions
The Infinity tuning software features the following controls:
EN
1. Connected and Disconnected. With this feature, you
can determine if the amplifier is communicating with your
Windows PC.
2. Low and High. With this feature, you can determine if the
amplifier is set to lo-level input or hi-level input on the amplifier
control panel.
3. Assign speaker locations to channels. With this feature,
you can designate the type of speaker and location in the car
each output channel of the DSP is connected to.
4. Individual channel volume control and muting. You can
raise and lower the relative volume level of each channel
individually to ensure perfect level-matching and output.
5. 0°/180° phase adjustment. You can set the phase of each
channel individually for balanced, dynamic performance.
6. Linking of paired channels. You can link paired channels to
apply volume and tone controls evenly.
7. Clipping indicator. Each channel features a clipping
indicator to let you know if 10% or greater distortion is
present. If it is, lower the volume level of the clipping channel
until the indicator turns off. For best results, measure with a
100Hz and 1kHz @ 0dB sine wave.
8. Time delay. With time delay, you can adjust the focal point of
the sound field to your desired location in the car. The closer
a speaker is to your desired focal-point location, the longer
its delay should be. To adjust, drag the slider to the right to
increase the delay, and to the left to decrease it.
9. Information display. This display shows you the following
statistics:
a. The master volume value
b. The current subwoofer volume level for channel 5 or 6, and
adjustable from -30dB to +6dB when using the remote
bass control.
c. The voltage the amplifier is reading at the power input
d. The amplifier's current operating temperature
e. Your current system configuration.
10. X-OVER. You can adjust the crossover points of the high-
pass and low-pass crossovers for each channel to maximize
the performance efficiency of each speaker connected to
the DSP Amplifier. The selectable crossover slope for each
channel can be set to 0/6/12/18/24/30/36/42/48dB.
11. Speaker location view. This shows which amplifier channels
are in use, and the locations of the corresponding speakers
in the vehicle.
12. Master Volume. You can raise or lower the volume of the
entire system, or mute the entire system. Drag the slider up to
raise the volume, and down to lower it. Click the speaker icon
to mute the audio system.
13. Write/Delete. "Write" lets you save up to 10 preferred audio
settings as presets, which you can apply to the amplifier. Click
"write", then click a preset number to save a preset. Click
"delete", then click a preset number to delete a preset.
14. Input Mixer. The Input Mixer feature lets you assign the audio
signal from an input channel to a specific output channel.
You can also sum the signals of multiple input channels and
apply the resulting signal to a specific output channel, usually
to allow a speaker to play the widest range of frequencies
possible when using speaker-level input signals.

EXAMPLE: If you have connected a tweeter (high-frequency
response only) to input channel 1 and a midrange speaker
(midrange-frequency response only) to channel 2, you can
sum the signals of each of these inputs, and assign the new,
full-range signal to a full-range speaker you have connected
to output channel 1.
15. Save File. This allows you to save saving a preferred audio
system configuration to a folder on your computer for use
later. It also allows you to retrieve a previous configuration
from your computer and apply it to your connected amplifier.
16. Settings. You can control the following options in the
"Settings" menu:
a. Language selection for the software: choose from English,
Spanish, French, Chinese, and Japanese
b. Power settings for delaying the amplifier turn-on/off should
your vehicle require either option
c. Firmware upgrades and resetting the software to original
factory settings
17. Reset Output. This button lets you reset the type of speaker,
and location in the vehicle, of each output channel.
18. EQ Mode. This lets you choose either a 31 band parametric
or graphic EQ to adjust for each channel.
19. Parametric or Graphic EQ. You can apply custom EQ
curves to each channel you have connected. To increase the
level of a given frequency, drag the slider up. To lower it, drag
the slider down.
20. EQ Setup. This EQ setup feature lets you click to select the
channels to which you want to apply EQ curves.
NOTE: The FREQ, GAIN, and Q fields shows the values
of the changes made by moving the EQ sliders. Only Gain
is adjustable when in Graphic EQ Mode. Frequency, Gain,
and Q are all adjustable in Parametric EQ Mode. These
adjustments can be made using the sliders or entering
specific values in the F, G, and Q fields.
21. Bypass EQ and Restore EQ. "Bypass EQ" allow you to
return your EQ settings to flat so you can hear the differences
made during your tuning. "Restore EQ" returns all EQ
adjustments to the previous settings.
22. Reset EQ – This button returns the EQ to factory settings.
