Audio Amplifier Phono Preamp Pre Amp Preamplifier with Level Volume Control RCA Input Output 1/4" TRS Output for Turntable

Product Description

Connect magnetic-cartridge vinyl turntables to modern amplifiers, studio monitors, or desktop sound systems using this low-noise phono preamplifier. Older turntables and newer models without built-in preamps send out a weak phono signal. If you plug them into a regular AUX input, the sound is barely audible and lacks deep bass. This active preamp fixes that. It takes the low-voltage signal from your turntable. Boosts it up to standard line level. At the time it applies the correct RIAA equalization. That means you get full sound, with good dynamic range and solid bass. Just like vinyl was meant to sound.

The preamp is housed in a metal case that helps block noise and interference. It has a built-in rotary volume knob so you can adjust the output level before sending the audio to your speakers or other gear. 

Key Features

Precision RIAA Equalization Circuit: It brings back vinyl sound and keeps the frequencies balanced while it lifts low‑voltage phono cartridge signals up to normal line level.

Variable Output Level Control Dial: The master volume knob allows you to match gain so that the signal does not clip or to raise signals before they reach active speakers or amplifiers.

Dual Output Connectors (Stereo RCA & $1/4\text{"}$ TRS): It gives you both standard left/RCA jacks and a balanced $1/4\text{"}$ ($6.35\text{mm}$) TRS stereo jack for studio monitors and mixing interfaces.

Dedicated Grounding Post Screw: GND terminal connects to turntable ground wires to cut background electrical hum and static noise.

Low‑Noise Operational Amplifiers: Internal low‑noise op‑amps give signal amplification without adding hiss or changing the sound.

Shielded Metal Chassis Construction: Heavy‑metal housing protects audio circuitry from electromagnetic (EMI) and radio‑frequency (RFI) interference.

Advantages

Bridges turntables that don't have a preamplifier with active speakers and home audio equipment that doesn't have a special "phono" input.

Adjustable gain control stops distortion when using high-sensitivity speakers or quiet recordings.

A $1/4\text{"}$ TRS output lets you connect directly to recording interfaces and studio equipment without needing any adapter cables.

A special ground screw helps stop the turntable loop hum for a clear sound.

Easy plug-and-play setup means no special software drivers or setup steps are needed.
