Initial Settings
1.After completing unit installation, wire, and appropriate audio signal connections, power-up 
the source unit, play a familiar track, and set the volume level to approximately 75%. 
2.Set all individual Graphic Equalizer Controls to 0dB. Master Volume Control and Subwoofer 
Level Control should be set to minimum, and fader set to even.
3.Press the Input Selection Switch to accept the input signal from the source unit or auxiliary 
source.
4.Set the CD Gain Selector setting appropriate to the pre-amp voltage of your source unit. 
Most source units provide 2V-4V pre-amp power. In this case, set the CD gain sensitivity to 
MID. If your source unit pre-amp voltage is higher, set the CD gain sensitivity to HI; if the 
voltage is lower, set the CD gain sensitivity to LOW. We recommend you never set the CD 
gain sensitivity to LOW with a source unit that provides a higher pre-amp voltage. This can 
create unwanted levels of distortion and possible damage to your 
Vibe 440PSU
5.Set the Subwoofer Frequency Selector switch to the desired low-pass filter. Generally, the 
low-pass filter is set to 128Hz, and then the subwoofer amplifier's low-pass filter is fine tuned 
for the desired response.
6.Adjust the Subwoofer Level Control to achieve the desired tonal balance between the front/
rear speakers and the subwoofer level.
7.Adjust the various individual Graphic Equalizer Controls to increase or decrease the output 
level of each frequency to achieve the desired response for the front stage and rear fill.
