Rainbow QPBB Instruction Manual

B/W QUAD PROCESSOR 

INSTRUCTION MANUAL 

Model: QPBB 

This real time, high resolution B/W quad is particularly designed for multi-camera CCTV systems.  The real 

time, high-resolution performance allows you to record all 4 cameras in quad view.  The separate switching 

output allows you to view each camera in full screen, quad, and switching (the unit will switch from camera 

to camera in full screen at 4 second intervals). 

Main Features 

•  Real time display 

•  High resolution 

•  Video gain adjustment for each camera 

•  Quad output (4 cameras on the screen at all times) 

•  Switching output (select each camera full screen or automatically cycle through each camera) 

•  Low power consumption 

Cautions 

•  Keep away from moisture, fire, and vibration. To avoid the risk of electric shock, do not remove the 

cover of the unit. 

•  Keep the temperature between 14° and 122° F (–10° and 50°C), relative humidity less than 85%. 

•  Keep the unit ventilated. Don’t put anything on the top of this processor. Do not expose it to extreme 

moisture.

Installation 

1.  Check that each camera is operating properly by connecting the video directly to the monitor. 

2.  Connect the coax video cable of each camera to the BNC inputs on the rear of the unit. (Item 3) 

3.  Connect the video outputs:  

The output labeled SWITCH connects directly to the monitor to allow switching between the cameras 

and to display the quad view. (Item 1) 

The output labeled QUAD ONLY (Item 2) normally connects to a VCR to record the quad image at 

all times regardless of what is shown on the monitor from the SWITCH output. (Item 1) 

4.  Adjust the gain of each camera if you find the image too dark or bright.  (Item 4)
