Douk Audio T14-EQ Phono Preamp MM/MC RIAA with Headphone Out

The Douk Audio T14-EQ is a compact phono preamplifier that converts MM/MC turntable signals to line level with RIAA equalization, tone controls, headphone output, and USB 5V power.

Small but feature-rich, the T14-EQ is designed for vinyl listeners who need an affordable, portable RIAA stage that supports both moving-magnet and moving-coil cartridges. Its metal chassis, low-noise circuitry, and flexible outputs let you feed an amplifier, powered speakers, or headphones without relying on an amplifier’s built-in phono stage. The unit’s USB power option also makes it an easy addition to setups that lack dedicated DC supplies.

How does the T14-EQ handle different cartridge types?

The T14-EQ includes selectable MM and MC input modes to match most common cartridge outputs. Switching between modes adapts input gain and loading so both higher-output MM and lower-output MC cartridges can be used without external step-up transformers. This versatility makes the preamp suitable for upgrade paths or shared rigs with multiple arms.

• Front-panel MM/MC selector for quick switching
• Optimized gain stages for both cartridge types
• Low-noise RIAA equalization designed for accurate vinyl playback
• No external SUT required for typical MC cartridges

What outputs and listening options are available?

The unit provides stereo RCA line outputs to feed an integrated amp or active speakers and a front 3.5mm headphone jack for private listening. The headphone output is capable of driving a wide range of headphones, giving you the choice between loudspeaker or personal monitoring without re-plugging cables in the back. Gold-plated RCA terminals preserve signal integrity when connected to downstream equipment.

• Stereo RCA outputs for amplifiers or powered speakers
• 3.5mm headphone jack supports 16–200Ω headphones
• Simultaneous outputs — use speakers and headphones without swaps
• Gold-plated connectors for lower contact resistance

How can I shape the sound with the T14-EQ?

Two independent tone knobs let you adjust treble and bass by ±5 dB, so you can correct for room acoustics or cartridge tonal bias. These subtle, musical adjustments help reconcile differences between speakers, headphones, or record pressings without resorting to equalizer plugins. Tone controls are simple and tactile, making on-the-fly tweaks easy during listening sessions.

• Independent bass and treble knobs for ±5 dB fine-tuning
• Analog controls for natural-sounding adjustments
• Useful for compensating room or cartridge coloration
• Works live with both speakers and headphones

What about noise, power, and build quality?

The T14-EQ uses a compact aluminum enclosure and high-quality PCB materials to minimize interference and preserve signal clarity. An internal power isolation stage and careful grounding reduce hum and ground-loop artifacts. The preamp runs from a 5V USB source, which makes powering convenient with phone chargers, power banks, or your computer.

• All-aluminum shell reduces electromagnetic interference
• Gold-plated PCB and RCA terminals for reliable signal path
• Built-in power isolation to lower hum and ground loop noise
• USB 5V power compatibility for portable or desktop use

Who is this for? The Douk Audio T14-EQ is aimed at vinyl listeners who want a compact, flexible external phono stage that supports both MM and MC cartridges. It’s ideal for users upgrading a basic receiver without a clean phono input, for desk-based listening with headphones, or for anyone who needs a portable RIAA solution that’s easy to power and integrate into multiple systems. Avoid if you require heavy audiophile-grade power supplies or elaborate parametric EQ — this product focuses on convenience, low noise, and straightforward tonal control.
