AP F8.9 bit /
USER’S MANUAL
6. Input Level Setup.
- Play track 1 from the CD provided with AP F8.9 bit.
Remark: if the head unit used is not equipped with a CD player, and only features a USB input, follow the instructions
below.
1) Copy the tracks in Wav format from the CD to the USB storage device.
2) Copy the tracks in mp3 format from the folder in the setup CD to the USB storage device, in case the first
player is not suitable to reproduce Wav formats.
- Set all tone controls to zero (flat).
- Set balance and fader to center.
- Adjust the head unit volume to the maximum undistorted output level.
- If the head unit provides an adjustable equalizer, make sure that the controls are set to zero (flat).
The input level calibration procedure is a delicate operation and must be performed very carefully. If not performed
correctly, it can nullify the final sound results.
Press BACK to return to the previous step.
Press GO to continue with the configuration.
Press CANCEL to exit the procedure.
Press SKIP to skip the level calibration procedure
WARNING: the head unit level must be adjusted to the maximum undistorted level. If the initial head unit distortion level can not
be determined, adjust the volume to approximately 80% of its maximum. If the head unit output level is set too low, the
device may produce ground noise (hissing sound) when playing music tracks.
This is due to the low signal / noise ratio provided by the head unit to the AP F8.9 bit input. If you experience this
problem, after calibrating the amplifiers sensitivity levels, increase the head unit volume and repeat the AP F8.9 bit
calibration procedure as detailed in point 9 of this paragraph.
Head units output level instrument check
The maximum output voltage and maximum undistorted level can be measured using the Audison bit Tune
SOURCE CHECK tool
(see sec. 7.1 bit Tune Advanced Manual).
