Line-Out Converter Specifications

Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
Maximum Power Input
This is the maximum amount of power (measured in watts) that the unit is designed to handle. Exceeding this amount can void warranties and damage the unit.

I would recommend this product for owners with a factory Bose system. Easy to install. I think it has a better sound after the install.

Well Built and Easy to Use

March 23, 2012

I needed a compact line out converter with balanced inputs and outputs, along with DC blocking. The Scosche OEA4 fit those requirements. It uses electrolytic coupling capacitors to block DC and balanced resistive attenuation circuits to drop the signal level. I measured the minimum attenuation at 13.5dB. From that level, a pot on each channel allows you to drop the level progressively to zero. I needed 20dB of attenuation and that was easy to get by adjusting the pots. The input impedance is around 500 ohms. I did not measure frequency response, but found no degradation of sound. The OEA4 was well built and about the size of a deck of cards (but twice as thick) making it small enough to fit where I needed it to go. The wire leads were pre-stripped and tinned, making soldering easier. The wire colors followed the standard speaker color code.
