Take a V2-400 and use the sub-woofer amplifier for the center channel. Then add a separate Digital Converter just for the added sub-woofer amplifier and you have the starting of a V5. 1. Next, put all the preamplifiers in the sub-woofer box and make a digital control box to remotely set the preamplifier gain controls. Below are the interconnections for the system.

The control pod and the satellite speakers shown are separate units; all other connections are internal to the subwoofer box. There is not much you can do about repairing the V5. 1 control pod. Klipsch moved all the pre-amplifier circuitry into the sub-woofer box. The control pod is just a remote control head now. A serial data stream from the control pod relays commands to adjust the volume level of the various channels. All the manual inputs are rotary encoders that are monitored by a microcontroller. With the exception of the encoders and a few transistors everything is done by the microcontroller program, which you can`t buy from Klipsch and for which we don`t have any data. Maybe someone can come up with an analog replacement circuit. The following block diagram of the control pods is marked to show basic operation of the pods and the differences between them. Click on the block diagram, or here to get schematic diagrams of the two control pods. The diagram for the V5. 1 DIN plug comes from tracing of the wires by Evan Shultz on his plug. Pins are identified by using the pin numbers on the control pod circuit board connector, J2, then continuing the sequence with the signals from J6 on the standard pod or J1 on the Ultra pod. The V5. 1 I/O board is very busy. The control pod is just that on the V5. 1, a control pod, so all the audio preamplifiers and headphone amplifiers had to be moved into the subwoofer box....
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
