line splitter distributes RCA output to 4 FX-AUDIO- LS-01J [Black] 4-channel & preamplifier, channels.

The gain can be set in two stages (0dB, +15dB) depending on the input level. Individual gain control is possible for each channel. A meticulously crafted op-amp with a 12V positive/negative power supply. It's easy to add it to your current setup using the familiar RCA connection. AC adapter required (sold separately) DC12V/1A DC jack 5.5mm x 2.1mm (center positive) 4ch LINE SPLITTER LS-01J This incredibly convenient item allows you to split RCA line-level signals into four separate outputs while maintaining signal strength! Each signal line has its own ON/OFF switch and volume control. An essential item for fully enjoying audio! Passive line splitters (RCA splitters) are limited to a maximum of two distributions, and four distributions are impractical due to problems such as deterioration of frequency characteristics due to combined line impedance and degradation of the signal waveform. However, when it comes to dynamic line splitters, the only options are professional equipment designed for balanced signals, making them a high hurdle for general users and not easily accessible. The FX-AUDIO- LS-01J solves all those problems!! With the ability to split the stereo RCA analog output into up to four outputs, you can easily compare the sound quality of multiple amplifiers, or compare and switch between systems based on different sources, without having to constantly reconnect cables! This is an excellent product that allows you to effectively utilize redundant audio resources such as amplifiers and speakers that you are not currently using. [Notes] *This product is a preamplifier. It is not a power amplifier, so a separate power amplifier is required to connect it to passive speakers. *When the output gain is increased using the GAIN setting switch, distortion or noise may occur if it exceeds the input tolerance level of the connected device. Please ensure that the input level does not exceed that of the connected downstream equipment. *Due to compatibility issues, the "NETGEAR AD2025F10" cannot be used as the power supply for this product. https://www.amazon.co.jp/dp/B091PNLN56/ref=myi_title_dp *Please purchase the recommended power supply listed below. *The product warranty period is 6 months from the date of purchase. *This product does not include a power supply.
