EQUALIZER BACKGROUND  
There are basically three types of equalizers: graphic, parametric and a  
hybrid of these two,often referred to as paragraphic. Additionally, there are  
passive equalizers, which have no gain, active gain preamps, which have a  
gain stage usually with a volume control, and booster equalizers which we  
won,t consider here since they are inferior passive equalizers with  
inexpensive IC amplifiers built-in.  
As in state-of-the-art home audio systems the optimum system requires a  
dedicated preamp with enormous gain to drive the various power amplifiers.  
Since home audio amplifiers do not have adjustable sensitivity, the require a  
high output preamplifier to drive them to maximum levels.  
This unit is the first production preamplifier to incorporate a specific  
bandwidth parametric equalizer with shelving control. With 18dB boost or  
cut on its four bands, it can compensate for acoustic anomalies unique  
to the automotive environment. The Vibe 440PSU easily becomes the  
Control Center of any high-end mobile entertainment system.

1.12V Constant Power Lead (red): This is themain power input for the Vibe 440PSU and must be  
connected to a (+)12V constant power supply. DO NOT connect this to a switched 12Vsource or  
the system may pop when the key is turned off.  
2.Remote Turn-On Input Lead (Blue): This is the input for turning on the Vibe 440PSU and system  
amplifiers. It should be connected to the (+)12V remote turn on output of the system head unit. The  
Vibe 440PSU has a built in turn off delay to prevent turn-off pops. When the remote turn on signal  
from the head unit shuts off, the amplifiers will turn off immediately and the Vibe 440PSU will stay  
on for five seconds before turning off. This feature is designed into the Vibe 440PSU to eliminate  
system turn off pops that can occur when several components turn off at the same time. DO NOT  
connect this to a (+)12V constant power supply.  
3.Ground (black): Connect this terminal to a qualityground location, preferably the chassis of the  
head unit, which must itself be properly grounded tothe vehicle chassis. It is not recommended  
that the factory radio ground be used for after-marketaudio components.  
4. High level connection cables: Most aftermarket audiohead unit have RCA (low-level) outputs.  
Plug the RCA output from the source unit into the RCA input of the Vibe 440PSU. If your  
audio source unit does not have RCA outputs, the Vibe 440PSU has the capability to accept high  
level (speaker level) inputs.  
5.SOURCE Input: These are the pre-amp stereo RCA audio inputs to be connected to the source  
unit's front pre-amp outputs.  
6.AUX Input: These are the pre-amp stereo RCA audio inputs to be connected to secondary source  
unit, or auxiliary device's pre-amp outputs.  
7.Sub Out: These are the pre-amp RCA audio outputs for sending the audio signal to the  
subwoofer amplifier.  
8.Front Output: These are the pre-amp stereo RCA audio outputs for sending the audio signal to the  
front speaker amplifier.  
9.Rear Output: These are the pre-amp stereo RCA audio outputs for sending the audio signal to the rear  
speaker amplifier.

Installation Instructions  
1.Read thismanual carefully andin its entiretybefore installing thisequalizer.  
2.Always disconnectthe battery orremove the fusesfor circuits youwill be workingon.  
3.Check for clearance of any hazards such as wiring harnesses or heater core before  
mounting the equalizerto any panelsin the vehicle.  
4.Mount the equalizer in a location that is easy to access and won't be distracting to  
vehicle operation whilemaking adjustments.  
5.Route all power wires and audio cables away from sharp metal edges that can cause  
shorts to ground and any moving parts that can tangle the wires such as heater controls  
or wiper motors.  
6.Route allpower and signalcables as faras possible fromother vehicle wiringharnesses.  
Loom when appropriate.  
7.It is recommended that the equalizer be grounded directly to the chassis of the head  
unit. The head unit should be grounded at a chassis point (preferably bare or scraped  
sheet metal) otherthan the factoryhead unit groundwire or underdash brackets.  
8.Use only thesupplied machine screws to mount the equalizer ordamage to the circuitry  
could occur.

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 CDGain Selector setting appropriate to the pre-amp voltage ofyour source unit.  
Most source units provide 2V-4V pre-amp power. In this case, setthe 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 CDgain sensitivity to LOW. We recommend you never set the CD  
gain sensitivity to LOWwith a source unit that provides ahigher pre-amp voltage. Thiscan  
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 desiredresponse.  
6.Adjust the Subwoofer Level Control to achieve the desired tonal balance between the front/  
rear speakers andthe subwoofer level.  
7.Adjust the various individual Graphic Equalizer Controls to increase or decrease the output  
level of eachfrequency to achievethe desired responsefor the frontstage and rearfill.
