-*-WARNING - READ BEFORE CHANGING PREAMP-*-
Always keep volume at middle range (50%) when changing the Preamp, as high Preamp could damage your speakers, headphones, earbuds and/or ears. By default, the Preamp is lowered to -3. Increasing it until +3 is relatively safe but be cautious of increasing it more than that without taking the previous precautions mentioned. High Preamp may also distort sound quality.
-*-The drivers must be reinstalled after every major Windows update.-*-
This is the first posting. Details and screenshots will be added and refined in the future. We will be able to post our own equalizer profiles for best audio settings as well, as we mess with it. The settings are stores in *\EqualizerAPO\config\config.txt.
Basic Device Setup:
1. Make sure the audio device you want to use/modify/test is connected.
2. Download Equalizer APO
a. https://sourceforge.net/projects/equalizerapo/
3. During installation, I set the location to C:\EqualizerAPO because they do not give you desktop shortcuts.
4. After the installation, you will be prompted for which audio devices you wish to use Equalizer APO for. You can choose one, or all. This can be changed later.
5. When you choose the device(s), it may require a restart, and all Windows will disappear.
6. Configuration:
a. To modify the equalizer and Preamp settings, launch C:\EqualizerAPO\Editor.exe
b. To change what devices use Equalizer, launch C:\EqualizerAPO\Configurator.exe
Laptop Speakers (includes headphone jack):
I had some difficulty getting it to change my Helios 300 (G3-571) speakers, but I found out how. Follow below:
1. After Equalizer APO installs, open the Configuration.exe.
2. Highlight Speakers, and check the 'Troubleshooting options' button.
3. Uncheck both 'Use original APO' buttons, and change Install as to 'Install as SFX/EFX (experimental)'
4. Restart and it should work.
5. Feedback is appreciated.
Frequency Table (to help with tweaking the equalizer):
Sub-Bass - 62Hz and lower
Mid-Bass - 62-125Hz
Upper-Bass - 125-250Hz
Lower-Mid - 250-500Hz
Middle-Mid - 500-1kHz
Upper-Mid - 1k-2kHz
Lower-Treble - 2k-4kHz
Middle-Treble - 4k-8kHz
Upper-Treble - 8kHz and higher

EDIT:BB23482 said:I recently purchased a predator PH315-51.
Everything was running good, But yesterday my dolby audio application started showing a message - 'Plug headphones or speakers into the system audio jack to enable Dolby Audio'. I've tried everything to fix it, Restarted my laptop several times, Reinstalled realtech driver many times, Turned dolby on and off from speaker properties, Even used Tweakbit driver updater to update drivers, but nothing seems to work.
Please suggest a solution.
MaxGamer said:Hi,
The same issues are present on my Nitro 5. The fix which works for me flawlessly is:
1. Open task Manager and go to Details.
2. Force closing these two Dolby services and then opening the Dolby App which restores the tray icon and the error also goes away.![]()
I don't know if its same on Predator series, but you can try.
I've had this issue as well today & in the past. An easy fix for me has been to go to windows services manager by typing services.msc in the run box. Then search for Dolby audio service, it's there with the name "Dolby DAX2 API Service", right click & stop it, hit ok. Then simply click on Dolby audio icon from the system tray & voila, it should be active & the service should be running automatically now. This is what worked for me. Give it a shot!!
