Today while browsing, i stumbled upon the service manual for Sony's A82x series walkman. Well being curious, I decided to get the test mode on my NWZ-A818, and guess what it worked!
For those who want to enter into the test mode quickly without reading the PDF, here are the following steps:
Setting method:
1. Turn the power on.
2. Press the [bACK] key for 1.5 seconds or more, the home menu is displayed.
3. Slide the [HOLD] key to set the hold on.
4. While pressing the [OPTION] key, press the key as following order: (up) → (up) → (down) → (down) → (right) → (left) → (up) → (down) → (up) → (down) → (right) → (play)
5. The set reboots when the [HOLD] key is slided to set the hold off, and the color bar is displayed in the liquid crystal display.
6. Enter the test mode when the [bACK] key is pressed in the state of step 5.
Aside from the fact that you can simply test to see if your walkman is working properly, there also seems to be some distinct settings that the user can manipulate. I'm talking about the mode for CLESTE (Clear stereo with and without cable) and DAC (audio gains for bass and treble). As of now, i'm not sure if changing these settings applies to only the player in Test mode, or applies to the player in general when playing music (hopefully for the latter!), or if it only applies to the player when custom EQ is set. We will have to see!
For the CLESTE mode, you can change the settings by pressing up or down, and for W/O cable, you can change it from -83 to -20. Not sure what it will sound at the moment. To confirm and save the settings you will have to push the start button.
Now here's the really interesting part, being the basshead that I am, I'm looking at the Bass gain settings. Not sure what it does, but apparently in this mode, you get set the gains for the following frequencies: 50Hz, 100Hz, 200Hz, and 250Hz. The settings for those frequencies are from -10.5 to 0. From what I'm entering now, it seems that you can only set one "DAC BASS GAIN" to all of the frequencies. I have mine on -9.0 and will see how it will sound later.
For the T-GAIN of the test mode under DAC, you can set the "DAC TREBLE GAIN" only to either 0 or 1.5 and applies to the frequencies of 5khz, 7khz, 10khz, and 15khz. I currently have mine on zero gain.
I would advice everyone who tinkers with this to WRITE DOWN YOUR PLAYER'S ORIGINAL SETTINGS. If you set the player to factory setting, it will not reset the settings under the test mode.
Have fun, let me know what all those gains in frequencies mean, and if you hear any apparent changes in your music, or if it at all works.
