Detail 01
61dB maximum gain
Plenty for condensers and most dynamics. Very quiet ribbons on distant sources may run out of headroom.

Universal AudioUA-S610 SOLO/610 Classic Vacuum Tube Microphone Preamp and D.I. Box
1/2
Independent shopping perspective
The Korena take
Single-channel tube mic preamp and DI built on the 610 circuit. For someone recording one source at a time who wants tube coloration on the way in.
Strong match
Who this is for
- Home studios tracking vocals or bass one source at a time
- Adding tube warmth in front of a clean interface preamp
- DI'ing bass or synths straight to the recorder
Consider the trade-offs
When to look elsewhere
- Anyone needing two channels or built-in compression
- Engineers who want transparent, uncolored gain
- Tracking drums or anything needing multiple simultaneous inputs
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Selectable 500 ohm or 2k ohm mic input impedance
Changes how the mic loads. Lower setting usually darkens and thickens; higher opens up the top end.
Detail 03
12AX7 and 6072 tube pair
Two gain stages you can retube later. Tube choice shifts the character more than any knob here.
Detail 04
Selectable 2.2M ohm or 47k ohm Hi-Z input
The 2.2M setting preserves passive pickup top end. 47k loads it down for a rounder bass tone.
Detail 05
20Hz to 20kHz +/-1dB
Flat across the audible band, so the color comes from the tube stage rather than a shaped frequency curve.
Final check
Know before you order
- 01One channel only. Stereo pairs or two-mic setups need a second unit.
- 02No compressor or EQ. Dynamics control happens elsewhere in your chain.
- 03Tubes drift over years and are a consumable replacement cost.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I plug my bass directly into it?
Yes. The front panel 1/4 inch jack is a Hi-Z instrument input with selectable 2.2M ohm or 47k ohm loading, so passive basses and synths both work.
02Does it have phantom power for condenser mics?
It is a mic preamp with a 61dB gain range and selectable mic impedance. Confirm the phantom power switch on the unit before pairing it with a condenser.
03Will this replace my audio interface?
No. It feeds a line-level signal into your interface or converter. You still need something to get audio into the computer.
04How is this different from the 6176?
The 6176 pairs the same style of 610 preamp with an 1176 compressor in one box. This is preamp and DI only.
