Phono Preamp EIMSOAH Dual Gain Compact Audio

Description

Product Overview

The EIMSOAH Phono Preamp is a compact audio component designed to bridge vintage turntables with contemporary sound systems. Housed in a sturdy 5.51 x 3.94 x 3.15 inch enclosure, it weighs just 10.9 oz, making it easy to place on any shelf or rack. Powered by an included DC 12 V adapter, the unit eliminates the need for external power solutions. Inside, a low‑noise op‑amp delivers up to 2 V (PP) output into 10 kΩ loads, while dual gain switches let you select the optimal amplification for moving‑mag or moving‑coil cartridges. The preamp’s high‑sensitivity circuit faithfully converts the weak phono signal to line level, preserving detail and dynamics.

Usage

Designed for both casual listeners and serious collectors, this preamp fits seamlessly into home audio setups, studio monitoring stations, and portable DJ rigs. Connect the turntable’s RCA outputs to the preamp’s stereo inputs, then route the line‑level outputs to a receiver, powered speakers, or a mixing console. The built‑in ground terminal helps eliminate hum, ensuring clean playback in living rooms, dedicated listening rooms, or on‑the‑go environments.

FAQ

Can I use this preamp with a moving‑coil cartridge?

Yes. The dual gain switch includes a high‑gain setting specifically designed for the lower output of moving‑coil cartridges, providing optimal line‑level conversion.

Do I need an external power source?

No. The preamp comes with a DC 12 V power adapter, so it can operate independently of a receiver’s phono stage.

Is the preamp compatible with both stereo and mono turntables?

The unit accepts standard stereo RCA inputs. For mono turntables, you can connect the single channel to the left input and leave the right input unconnected.

How do I reduce hum in my setup?

Connect the ground terminal on the preamp to the turntable’s grounding screw. This creates a low‑impedance path that eliminates ground loops and hum.

What is the warranty period?

EIMSOAH offers a one‑year limited warranty covering manufacturing defects and component failures.
