Review on 🔌 High/Low Impedance Adaptor - Car Audio System RCA Line Output Converter Adapterwith Adjustable Level Control - Ideal for Vehicle Amplifiers, Equalizers, Home Theater Setups - Pyramid NS60 by Tanner Miller

Because most newer TVs have an optical audio output and an analog audio output, the output of these two devices is single-stage, meaning they are not controlled by the TV's volume control. I needed a way to connect to the TV's speaker outputs to get a standard line output that could be controlled by the TV and the TV's remote. This device was optimally tailored to the needs, but only after ordering and installing three different line output converters that had problems with design and application. I look at the quality of thought behind the design. Yes, the input wires are quite thin and the soldering quality isn't the best, the overall design of the device is very good. Other LOCs I've used either had problems with hiss or hum (even when grounded) or caused noticeable sound distortion. This device uses good quality audio isolation transformers to separate the input from the output. It's a bit dated, but it works, and it works better than anything I've used. The first thing I did was open the device and remove the solder joints. While most were fine, there were a few that needed some attention. They just needed some cleaning from the extra lengths of wire and two cold solder joints. I then unsoldered the existing input wires and installed a good solid 22 ga stranded wire in their place. Converter. Once installed the LOC worked great and I set the LOC to the same volume as the internal speakers. The photo shows the LOC setting on the back of the TV, as well as the audio output selector switch. If your application converts your TV's speaker output to a line level output for external powered speakers or an amplifier, then this is what you're looking for!
