B855 LINEPAUDIO เครื่องขยายสัญญาณโทรศัพท์ก่อนเครื่องบันทึกเสียงพร้อมช่องต่อเสริมและควบคุมเสียง

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.
