About The Product
1. Mini passive stereo mixer is a stereo four-way passive mixer for extended control tuning, mixing instrument, CD player, tape player, computer, mobile phone, tablet and so on. No battery or other power source required. The device can also be used as 1 In 4 Out stereo distributor clockwise to adjust the volume.
2. OUTPUT: is used to connect RCA jack to mixer output or other output devices.
3. IN 1-4: controls the signal level from input 1-4.
4. 4 groups of stereo RCA input and 1 group of stereo RCA output.
5. Four independently regulated 100K ohms potentiometers.

Feature
1. Input impedance: 10K ohms to 47K ohms
2. Output impedance: 2.5K ohms to 10K ohms
3. Gain: -12dB MAX

About The Product
1. The LINEPAUDIO phone preamplifier adds phonograph functionality to any amplifier or receiver with standby auxiliary level input.
2. Prephonograph signal amplifier with AUX input and volume control, and AUX is with no signal amplification function.
3. The Phono preamplifier adds a phonograph function to any amplifier or receiver having standby AUX / CD / DVD audio line level input.
4. It can also be used to drive the disc directly into a mixer or a computer sound card. With its precise RIAA balance and 80 dB S / N ratio, the product can also be used to input the turntable directly into the sound system of the mixer or a computer. In order to switch auxiliary input to replace stereo or computer use, eliminating the need of connect and disconnect of the source signal as well as the sharing connection of the product. The sound quality of the preamplifier is easy to match or exceed the sound quality of the phonograph preamplifier built into a high-quality stereo component.
5. Product configuration switch function selects AUX input instead of stereo or AUX input port occupied on the computer. There is no need to connect or disconnect a shared input signal source of the product.
6. The output level control is very convenient to use the sound card and allows for the elimination of the largest signal difference between the switched signal sources.
