1.12V Constant Power Lead (red): This is the main power input for the Vibe 440PSU and must be connected to a (+)12V constant power supply. DO NOT connect this to a switched 12V source 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 quality ground location, preferably the chassis of the head unit, which must itself be properly grounded to the vehicle chassis. It is not recommended that the factory radio ground be used for after-market audio components.
4.High level connection cables: Most aftermarket audio head 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.
