Pyramid High Low-Level Impedance Adaptor - Car Audio System RCA Line Output Converter Adapter w/ Adjustable Level Control - Works on Vehicle Amplifier, Equalizer, Home Theater Setup - Pyramid NS60

Since most new TVs have an optical audio and analog audio out, the output of both these devices is single level, meaning they are not controlled by the TVs volume control. I needed a way to tap into the TV's speaker outputs to give me a standard line level output that was controllable by the TV and the TV's remote. This device fit the needs perfectly, but only after ordering and installing three different Line Output Converters that had problems with design and application.While some people who reviewed this Line Out Converter (LOC) stated that the quality of the unit is sub-par, I look at the quality of the thought behind the design. Yes, the input wires are pretty thin, and the solder quality is not the best, the overall design of the unit is very good. Other LOC's I've used either had a hiss or hum problem, (even when grounded), or caused a noticeable distortion of the sound.This unit uses good audio isolation transformers to isolate the input from the output. It's somewhat old school, but, it works, and it works better than anything else I've used.The first thing I did was open the unit up and clean up the solder joints. While most were fine, there were a few that needed some attention. They just needed some cleanup from extra wire lengths and two cold solder joints. Then I desoldered the existing input wires, and installed good, solid 22 Ga. stranded wire in their place.I used a 4-pole double throw switch mounted in the back of the TV panel to allow selection of the internal speakers or the audio out converter. Once installed, the LOC worked perfectly, and I adjusted the LOC for the same volume out as the internal speakers.The photo shows the LOCs installation on the back of the TV, as well as the switch for selecting the sound output.If your application is conversion of the speaker output inside your TV to line level outputs for external powered speakers or an amplifier, then this is what you are looking for!

Works great for what I needed it for. I wanted to connect my old (15 years old) CD player to my new 7.1 surround sound system. The CD player only had speaker wire outputs and the surround sound system only accepted digital optical audio, HDMI, or RCA cables. I used this and it worked great with excellent sound quality from the CD player. It is also reasonably small so it stays well hidden even behind my small CD player. For the price, it is well worth trying. I think that it is mostly meant for car audio systems, but it worked great for my needs. I am sure that it would work just as well for record players or other stereo systems to convert the speaker wire to RCA. I don't listen to many CDs anymore, but it is nice to have the option to.

It does what it is advertised to do. It provides a low level (preamp level) output directly from a speaker system. The output is clean and undistorted. No power rating is listed on the item but from the size of the coils, I would guess it is no more than 20 or 30 watts a channel. It works well with 15 to 20 watt tube amps in the Hammond organs where I installed the units.

Theres holes in the casing and plates on the board in the circuit for pontentiometer placement, but theyre absent. Very strange. Super cheap hardware for one simple job, works ok, low quality wiring as to be expected.

I spent many hours trying to eliminate subwoofer hum and level issues in my home 2-channel audio system. I installed two of these (one for each channel due to the distance of my mono-block amplifiers--you only need one if you're dealing with a stereo amp). As others have commented, the fabrication seems very flimsy with thin wires, etc., but they work!

First thing I noticed when I opened it is nothing holds the inlet wires in place. They just flop around and move in and out so I secured them before their flimsy wires could get ripped out. Second thing is one of the channels has it's polarity reversed! I have a mono block amp and after hooking up I had almost zero power coming out after playing with adjustments on LOC I realized I did on both channels as long as both channels weren't turned up at the same time. So I triple check my wiring with multimeter. Channel one positive DC volts with red lead hooked up to solid wire and black to striped wire (which is what is stated on pyramids label) and same results with second channel. So yeah pyramid had 4 wires they needed to solder in the correct position and managed to mess up 2 of them. That's a 50% failure rate. Tried to contact the manufacturer through the website listed on package but website url doesn't work. Their programmers must have mixed up some line of code when setting up the website which isn't surprising seeming they can't get 4 wires in the proper place.
